Cargo tank cleaning - A Continuing Hazard


An explosion off Penang, Malaysia, on board an oil/chemical tanker that killed one and injured five other crew members has been attributed to crew carelessness, manifold piping complexity, and dilatory maintenance.

Due to the incompatibility of the two grades of cargoes being shipped, the port side and starboard side common manifolds were used for discharging nitric acid and acrylonitrile, respectively, in order to follow the segregation requirement.
On 17th April, 2016, the Hong Kong registered 12,395 dwt tanker, the ‘No.3 Heung-A Pioneer’, arrived at Port Kelang and discharged about 6,800 tonnes of nitric acid that had been loaded in six tanks, two on each side of the vessel.
Discharge took place through the port common manifold, with the elbow spools connecting the port tanks to the manifold. The spools remained in place after the cargo had been dispatched. The vessel sailed the same day for Penang, and on the next day unloaded one grade cargo of about 2,000 tonnes of acrylonitrile through the starboard common manifold, with elbow spool pieces used to connect the starboard individual manifolds.
During the unloading operation, the crew discovered that the shut-off valve on the port individual manifold from cargo tank No. 8 was leaking, and they reported it to the Chief Officer.
The tanker sailed in a ballast condition, on route for Singapore. Thirty minutes out, the Chief Officer held a 20 minute cargo oil tank cleaning safety meeting with deck crew.
During the preparation for the tank cleaning operation, an elbow spool piece was wrongly fitted from the port common manifold to the port tank No. 8 individual manifold. As a result, the acrylonitrile residue was able to creep through the leaking manifold shut-off valve of tank No. 8 to mix with the nitric acid residue in the port common manifold.
Around eight minutes after cleaning began, a violent explosion occurred at the port side common manifold at main deck level, injuring six crew members on deck. The tanker returned to Penang and the injured crew members were sent ashore for medical treatment. One of them was certified dead in the hospital on the same day.
Investigation
The investigation, conducted by the Marine Accident Investigation and Shipping Security Policy Branch of the Hong Kong Marine Department, reached the conclusion that the ship management company of the vessel should:-
a)    Inform all Masters, officers and crew of the fleet on the findings of this accident investigation;
b)    Issue safety instructions on handling leaking valves of cargo oil pipelines during operation;
c)     Provide on board familiarisation training to crew of the cargo manifold piping arrangement;
d)   Review the on board procedures for handling incompatible cargoes, taking the following aspects into consideration:
Ø full risk assessment should be conducted for the tank cleaning operation;
Ø particular caution should be highlighted when using the common manifold. The ‘line-up checklist’ should include the use of elbow spool pieces to avoid any violation of the segregation requirement;
Ø procedures should be developed such as
Ø using warning signs, chain lock/seal or barrier on the individual manifolds to prevent them from being wrongly connected to the common manifold which may contain incompatible cargo;
Ø cargo compatibility information should be readily available to all crew members for reference;
Ø crew members involved in the cargo tank cleaning operation should attend all relevant safety and tool box meetings.
Tanker owners and operators will also be sent a Hong Kong Merchant Shipping Information Notice to promulgate the lessons learnt from the accident.

Singapore to ban open loop scrubber discharges


Ships fitted with open loop scrubber systems to meet the 2020 sulphur cap will be banned from discharging wash water in Singapore’s waters the Maritime and Port Authority of Singapore (MPA) has announced.
The ban was revealed at an event in Singapore to promote the Singapore Registry of Ships when retiring MPA CEO, Andrew Tan said in a speech, “To protect the marine environment and ensure that the port waters are clean, the discharge of wash water from open-loop exhaust gas scrubbers in Singapore port waters will be prohibited."
Tan went on to say that ships with open loop scrubbers will be required to switch to compliant fuels while those with hybrid scrubbers must to switch to closed loop operating. He also said that Singapore will be providing facilities for the collection of residues generated from the operation of scrubbers.
The move has come as a surprise to many, but Reuters has reported that The MPA told it that the ban "is already part of our current legislation" but that its enforcement would start from Jan 1, 2020.
In a press release issued today (30 Nov), MPA has said that it has released two technical guidance booklets for Singapore-registered ships and ships calling at the Port of Singapore. The booklets outline the options available for ship operators to comply with the new regulations which include the use of approved abatement technology such as scrubbers, alternative fuels and compliant fuel oil.
Both booklets are now available on the MPA website.
Although all ships with open loop systems will be barred from discharging wash water in Singaporean waters, Singapore-flagged ships will be permitted to have open loop scrubbers installed.
The booklet for Singapore-registered ships contains information on all 2020 compliance options and says “For ship operators that choose open loop scrubbers, they should take notice of the various ports globally that have prohibited the discharge of wash water from open loop scrubbers in their port waters. Plans should be in place for such vessels operating at these ports, such as the use of compliant fuel instead”.

Berthing in Hong Kong Waters


Currently, vessels berthing in Hong Kong waters (excluding the first hour after arrival and the first hour prior to departure) are required to use fuel oils whose sulphur content does not exceed 0.5% by weight, liquefied natural gas or other fuels approved by the Hong Kong authorities. 

However, in accordance with the "Air Pollution Control (Fuel for Vessels) Regulation", not only vessels berthing, but also vessels sailing in Hong Kong waters on or after 1 January 2019 shall be required to use fuel oils whose sulphur content does not exceed 0.5% by weight, liquefied natural gas or other fuels approved by the Hong Kong authorities. In addition, the following must be recorded in the vessel's log book, and this log book, the bunker delivery note and the written procedures for conducting a switching operation must be kept on board the vessel. 1. the date and time when the vessel enters the Hong Kong waters; 2. the date and time when the vessel exits the Hong Kong waters; 3. the date, time and position of the vessel when a fuel switch operation to compliant fuel is completed on the vessel; 4. the volume and sulphur content of the compliant fuel carried on the vessel for operating its specified machinery when a fuel switch operation to compliant fuel is completed on the vessel; 5. the date, time and the position of the vessel when a fuel switch operation to non-compliant fuel commences on the vessel; and 6. the volume and sulphur content of the compliant fuel carried on the vessel for operating its specified machinery when a fuel switch operation to non-compliant fuel commences on the vessel. For further details regarding this regulation, please refer to the attached L.N.135 of 2018 "Air Pollution Control (Fuel for Vessels) Regulation".




Ships forced to discharge waste in Argentine ports


Introduction
Local authorities have increasingly exercised their power to enforce local regulations concerning waste disposal and broadened the responsibility of vessels in this regard. It has become common practice for local authorities to request the compulsory discharge of waste from vessels, even if this action appears to go against commonly accepted international law that is binding in Argentina.
Many shipowners are concerned with the fact that inspectors are boarding vessels at berth and requesting that they discharge waste due to "deficient sanitary conditions" even if the vessels have a "garbage management plan" under Annex V of the International Convention for the Prevention of Pollution from Ships (the MARPOL Convention). This situation is exacerbated by the fact that most of Argentina's up-river port terminals, if not all, have no facilities to receive waste from vessels. Cases have also been reported in which unrequested barges have waited alongside vessels while inspectors were on board to verify their waste storage rooms to put pressure on the master to undertake waste discharge.
MARPOL Convention
Argentina is party to the MARPOL Convention and hence its revised Annex V (as per resolution MEPC.201(62)) should be followed in Argentine ports. In contrast, local authorities have recently invoked a domestic regulation (Regulation 714/2010) to inspect vessels and in most cases, if not all, have required waste discharge.
From a phytosanitary perspective, local authorities other than the Coastguard can inspect ships and check whether they comply with local regulations on organic residues, but they do not have the power to inspect other conventional types of waste (eg, plastics or domestic or hazardous waste). This has caused a conflict of jurisdiction between local authorities – namely, the National Service of Agri-Food Health and Quality (SENASA), as the phytosanitary and zoosanitary authority, and the Coastguard as the primary maritime authority in Argentina.
According to Article 3.13.3 of Regulation 714/2010:
SENASA in its capacity of enforcement authority of the "Plan Nacional de Residuos" (National Garbage Plan) may require the discharge of garbage according to the provisions of this regulation when situations and health reasons so request. If the authority of the vessel or the local agency refuses to comply with the above, a written record must be issued and this shall be informed to the competent authority of the jurisdiction where the vessel is in order to comply with it and carry out the discharge.
Comment
The MARPOL Convention takes precedence over Regulation 714/2010 in the Argentine legal framework. Under the regulation's criterion, local authorities can request the discharge of vessel waste for health reasons. However, this rule is unlikely to be triggered if a vessel has a "garbage management plan" pursuant to the revised Annex V of the MARPOL Convention.
If inspectors request that a vessel discharges its waste, the master may refuse to do so. Under Regulation 714/2010, the master's refusal must be certified and the competent authority must be informed in order to comply with the regulation. In this regard, and although it is not mentioned in Regulation 714/2010, the competent authority is the Coastguard, pursuant to Article 2 of Act 24,089. The Coastguard must check whether the vessel complies with the MARPOL Convention, normally in the context of port state control.
The current regulations are expected to be reviewed and the existing scenarios in this regard could change if the government passes a bill entitling only the Coastguard to inspect ships during inward clearance at anchorage and before berthing.

Is Your Notice of Readiness Valid?


The English High Court recently held that a Master had not tendered the Notice of Readiness (“NOR”) within port limits despite the vessel being anchored in a location directed by the Port Authority.  Accordingly the NOR was invalid.
The consequences of tendering an invalid NOR can mean, in the case of a voyage charter, that the laytime provisions do not kick in. Ultimately this may mean the loss of a considerable amount of demurrage for an owner.

 The Notice of Readiness
The form and content of a NOR will depend on the terms of the charter party. However, it must state that the vessel has arrived at the agreed destination where she may tender the NOR pursuant to the charter party. It must also state that she is ready to load/discharge.
A voyage charter will either be a berth charter or a port charter.  If the charter is a berth charter then, unless there is a clause in the charter party allowing the Master to tender the NOR earlier, the vessel must be securely moored at the berth before she can tender her NOR. If the charter is a port charter then, provided the ship has arrived at the port, she can tender her NOR.  It is not uncommon for berth charters to allow the NOR to be tendered when the vessel arrives at the port if the vessel cannot proceed to the berth, e.g. because the berth is congested.
Most voyage charter parties start the running of laytime after a valid NOR has been tendered. Therefore, if an invalid NOR is given because the vessel is not at the agreed place, then laytime will not start to run.
Is the vessel within port limits?
Unless there is a “WIPON” (“whether in port or not”) clause in the charter party, allowing the NOR to be tendered outside the port (and, thus, meaning the NOR will be valid even if tendered outside port limits), it is extremely important to tender the NOR within the port limits. If the charter is a port charter and there is no WIPON clause then the vessel must be within the port limits to tender a valid NOR.
In the case of The MV Arundel Castle the fixture recap provided that the NOR was to be tendered within the port limits. The load port in question was Krishnapatnam, which was congested at the time. Due to the congestion the vessel was unable to proceed straight to the berth. Therefore, the vessel instead anchored at a location directed by the Port Authority. There the Master tendered the NOR.
The Charterers urged the court to hold that “Port Limits” means the geographical port limits as shown on the admiralty chart. The chart produced by the Charterers showed an area described as “Limit of Port of Krishnapatnam”.  In the instant case, the vessel was anchored outside this area at a distance of 1250 meters.
While the owners accepted that the vessel was outside the port limits by reference to the admiralty chart, they sought to argue either:
A. that the term “Port Limits” in the charter party included any area within which vessels are customarily asked to wait by the authority and over which the Port Authority exercises authority and control over the movement of shipping. On the basis of this definition, because the Port Authority at Krishnapatnam ordered the vessel to wait where she did, the owners argued, the vessel was within port limits; or
B. that by using the definition of “Port” in Laytime Definitions for Charterparties 2013 and The Baltic Code 2014, “Port Limits” includes any area where the vessels load or discharge cargo including berths, wharfs, anchorages, buoys and offshore facilities, as well as places outside the legal, fiscal or administrative area where vessels are ordered to wait for their turn no matter the distance from that area. Again, because this vessel waited where she was ordered to wait by the Port Authority the owners claimed that she was within the port limits when the NOR was tendered.
The court followed the decision in The Joanna Oldendorff [1973] 2 Lloyds Rep 285. This case states that to be an arrived ship or vessel must have reached a position within the port where she is at the immediate and effective disposition of the charterer, with such position usually including the normal waiting place, although that will not always be the case. Relying on conclusions from the judges in The Joanna Oldendorff, the court in the present case held that:
(I) where there is a national or local law that defines the port limits, these are the limits that will apply;
(II) where there is no such law then a good indication of what the port limits are is given by the area of exercise by the Port Authority of its powers to regulate the movement and conduct of ships.
(III) In the present case, however, because the parties did not provide any evidence of local or national laws, or any information showing the area where the Port Authority can exercise its powers of vessel movement, the arbitrators were entitled to reach the conclusion that the vessel was not within the port limits by reference to the admiralty chart. It is interesting to note, however, that had the owners been able to provide evidence to show a national or local law defining the port limits differently, or evidence as to the port authority’s powers in a wider area, then the court may have decided the case differently.
The Golden Rules
1. Know whether or not you are within the port limits.
Just because the Port Authority has directed a vessel to wait for a berth at a particular place, this does not mean it is within the port limits. The Port Authority, agent or admiralty sailing directions may provide this information. If not, or if in any doubt, obtain advice as to whether there are any local or national laws defining the port limits. If there is no such law then obtain information about the area within which the Port Authority can exercise authority and control over the movement of ships.
2. An invalid NOR cannot become valid – keep tendering new NORs “without prejudice”
Once the ship gets to the correct position for the purpose of tendering a NOR then a new NOR must be tendered. If in doubt, or indeed in any event, when there is a change in the vessel’s position tender a new NOR “without prejudice” and keep issuing new NORs “without prejudice” to the earlier NORs. This should mean that, even if the first NOR is not valid, then one of the later ones will be. If no new NOR is given after an invalid NOR then it is likely that laytime will only start to run once the vessel starts loading/discharging.
3. Include a WIPON clause in the charter party
If the vessel is going to go to a port where it is possible it will be ordered to wait outside of the port limits then the owners should seek to include a WIPON clause in the charter party. As noted above, this should mean that the Master can validly tender NOR once at the waiting place even if this is outside the port limits and the NOR will be valid.
Most voyage charterparties make the commencement of laytime conditional on the tender of a valid notice of readiness. If the notice is invalid, then in the absence of a waiver by charterers (on which see below) laytime will not commence at all, even if the charterers knew or ought to have known that the vessel was in all respects ready. The tender of a valid Notice of Readiness and the subsequent commencement of laytime has been a fertile area of debate in the English courts, this past year or so being no exception with the much commented cases of the "PETR SCHMIDT" [1998] and the "AGAMEMNON" [1998] being heard. These have assisted in the development and clarification of this area of the law.
OVERVIEW
General Observations
If a notice is required but none is given then strictly, laytime will not start to run.Arbitrators may however, take a more commercial view and decide on the facts that the charterers were aware or ought to have been aware that the vessel was ready to load and knew that loading was taking place, and that therefore laytime should commence on loading. The burden of proof, however, is on the owners to show that laytime should start to run even though a notice of readiness was not given. This is not satisfactory from the owners point of view as there is no assurance for them that laytime will commence at all.
Where a notice is required then in the absence of an express provision to the contrary, this is required only at the first load port and not at the subsequent load ports or at the discharge port(s).
At common law, the notice may be given orally or in writing.
The notice of readiness is the notice to the charterer, shipper, receiver or other person as may be required under the charterparty that:
(1) The vessel has arrived at the specified destination where the notice of readiness can be given. The question of whether the vessel is an "arrived" one for the purposes of commencement of laytime has been the subject of much discussion and case law which is outside the scope of this article. However, it can be said briefly that the specified destination will depend on the terms of the contract; if the charterparty is a berth charterparty then the specified destination is the nominated berth or, if a berth has not been nominated, it will be the first available berth to which the vessel is ordered and the notice of readiness may be tendered at that place subject to the other conditions being satisfied. If, however, the charterparty is a port charterparty then the notice of readiness must be tendered when the vessel is in berth within the specified port or, if a berth is not available, when the vessel is within the port limits and at the waiting area where vessels usually wait for a berth.
Various clauses in the charterparty may advance the time that the vessel may tender the notice even though she may not be at the specified destination. The most familiar is the WIBON ("whether in berth or not") provision which means that under a berth charterparty, if the berth is not immediately accessible, the notice of readiness may be given when the vessel is in the port in which the berth is situated.
Similarly a WIPON ("whether in port or not") provision will enable the notice in certain circumstances to be tendered even if the vessel has not yet entered the port area.
(2) The vessel is ready to load or discharge the cargo as the case may be. This means that the vessel must be both physically ready in that the holds are ready to receive the cargo and legally ready in that all documentation necessary to enable her to commence loading is in order. If, however, the vessel is ready subject only to a mere formality then the notice may still be able to be tendered. For example, if customs clearance is only obtainable on berthing but the notice can be tendered when the vessel is off berth then this will not affect the vessel
s readiness.
(3) All other requirements under the charterparty concerning the form, timing and the party to whom the notice is to be tendered have been complied with.
Validity of the notice of readiness.
A notice of readiness therefore contains several statements of fact. In order to be a valid notice, those statements must be true. If the statements are incorrect the notice is invalid and a nullity so far as the contract is concerned and ineffective to start laytime. Further, as was made clear in the leading authority of the "MEXICO I" [1990] (described below), if the statements were untrue when they were made, the notice does not subsequently become valid when the circumstances change. If therefore, there is any doubt as to the validity of the notice, it is always advisable for the master to tender a further notice.
The "MEXICO I" [1990] 1 Lloyd’s Rep 191
The owners let their vessel to the charterers for the carriage of a part cargo of maize from Argentina to Angola. Under the charterparty, the owners had a right to complete the vessel with other cargo. On completion of loading, the vessel was also carrying a cargo of beans for the same charterer under another agreement. Both the maize and the beans were overstowed by parts of the completion cargo. On arrival at the discharge port, the vessel tendered notice of readiness (on 25th January). However, at the time of tender neither of the charterers cargo was accessible due to the overstow of the completion cargo. The charterers maize cargo became accessible on 6th February and the beans on 19th February which is when discharge of both cargoes commenced. The owners claimed that laytime commenced when the cargo became fully accessible on 6th February. Charterers on the other hand claimed that time commenced only when discharge actually commenced on 19th February.
The Court of Appeal held that the notice was invalid and a nullity when given and ineffective therefore to commence laytime even if the charterers knew or ought to have known of the vessel
s subsequent readiness. Accordingly, the charterers were entitled to insist on a further notice of readiness in order for laytime to commence unless they had in the meantime waived their right to a further notice or agreed that it would not be necessary. On the particular facts in this case, the Judge found that although the notice was invalid, the charterers had nevertheless accepted it via their agents on the commencement of discharge. As a matter of principle, however, the judge confirmed that an acceptance of an invalid notice in circumstances where the charterers were unaware of the inaccuracy in the notice could not bind the charterers and they were not prevented from subsequently disputing the effect of the notice. What will constitute a waiver of the defect or acceptance of an invalid notice is considered in more detail below.
Unless there is provision to the contrary in the charterparty, the statements in the notice must relate to the time that they are made and when the notice is given. There is a distinction however between an invalid notice and one that is uncontractual in that it has been tendered to the wrong party or at the wrong time of day. A notice that falls within the second category may still be regarded as valid. The law in this area has recently been clarified in the following recent cases.
The "AGAMEMNON" [1998] CLC Rep 106
The "AGAMEMNON" was chartered to load a cargo of steel pipes from Baton Rouge to Brisbane. The charterparty provided that the vessel was at the South West Pass and "ready to proceed to loading port weather permitting". The South West Pass, however, was 170 miles from Baton Rouge and it did not form part of that port. A notice of readiness was tendered at the South West Pass. It was not until two days later however that the vessel arrived at Baton Rouge general anchorage but, due to the designated berth being unavailable, loading did not commence until later the following day.
The charterparty provided that if the berth was not available on the vessels arrival at the port or so near thereto as she may be permitted to approach, the notice could be tendered on arrival and laytime would then commence as if she were in berth and in all respects ready.
The charterers considered that the notice of readiness tendered at the South West Pass was premature, since it was given prior to the vessel
s arrival at a point so near to Baton Rouge as she could approach i.e. the Baton Rouge general anchorage, and as no notice was given when the vessel reached that point later, laytime did not commence until loading started.
The charterers failed to persuade the arbitrators to agree with this view, but on appeal, the Judge found in their favor. In accepting their arguments, the Judge relied on the Court of Appeal decision in the "MEXICO I" [1990] which made clear that when a notice is to be given in order to start laytime running, this must be a valid notice and not an "inchoate" or "delayed action device" seeking to commence laytime automatically on the happening of a certain event. In such cases, a fresh notice must be given. Applying that case to the facts before him, the Judge found that the notice of readiness in this case represented that the vessel was at the place at which it was permissible for the notice to be tendered (the Baton Rouge anchorage). This was clearly not the case and the notice was therefore invalid and could not trigger the commencement of laytime.
The "PETR SCHMIDT" [1998] C.A.
In this case, the charterparty provided that the notice of readiness had to be tendered to the charterer or his agent within 0600 and 1700 hours local time and laytime was to commence six hours from the receipt of that notice or upon the vessels arrival, whichever first occurred. Of the various notices given at the load and discharge ports, one was given at 0100 hours and the other two at 1800 hours. The charterers argued that since the notices were tendered outside the specified period they were non-contractual being in breach of the relevant clause and therefore invalid and of no effect in accordance with the principles in the "MEXICO I".
It was common ground that (a) when the notice of readiness was given the vessel had then arrived at the appropriate place within the port in question (b) the vessel was in fact ready to load or discharge as required by the charterparty and the statement of readiness was therefore correct (c) the vessel continued to be ready and (d) no further notices were given.
In their judgment, the Court of Appeal confirmed the principle decided in the "MEXICO I" namely, that in order to be a valid notice, it must contain accurate statements of existing fact. In the "MEXICO I" the notice stated that the vessel was ready when in fact she was not and the notice was therefore invalid. In the "PETR SCHMIDT", however, the notice was correct in that the vessel was ready and at the required place but was sent to the charterers outside office hours. The Court drew a distinction between the requirement to "tender" a notice of readiness and to "give" or to "receive" one. The Court found in this case that the telex notice was sent out of office hours but was "tendered" at the receivers
office opening at 0600 hours the following morning and that this therefore complied with the charterparty requirement. However, the Court also considered what the position would be if the charterparty required the notices of readiness to be "given" or "received" by charterers within certain periods and they are in fact given or received outside these periods. The Court held that in such cases (provided the notice was otherwise correct) the notice would be non-contractual and therefore wrong but not invalid at the time it was given. The practical effect of a non-contractual notice which is tendered outside the required time is, that while it may not be effective to start the laytime clock running, the defect may be "cured" by, for example, the passage of time and laytime will start at that point. As the Court pointed out, whether the defect can be so "cured" is a question of fact rather than the law and will vary from case to case.
The charterers may choose to accept an otherwise invalid notice. However, this acceptance must be in clear terms and in these circumstances owners will leave themselves open to the argument that this acceptance was induced by an incorrect representation in the notice as happened in the "MEXICO I". In those cases, the charterers would not be precluded from disputing the effect of the invalid notice.
Acceptance/Waiver by charterers.
In other cases the charterers may be regarded as having accepted the invalid notice with full knowledge of the defect, or as having waived the defect such that they are subsequently estopped from relying on it (such as in the "SHACKLEFORD" [1978] 2 Lloyd’s Rep. 154). Whether there has been such an acceptance will depend on the facts of each case. However, as expressed in the "MEXICO I", at the very least it must be shown that there was some kind of bilateral representation and conduct by the parties to provide evidence that the original contractual arrangement as to the commencement of laytime had been replaced by something new.
CONCLUSION
It will be seen from the above that the recent cases have clarified the law. However, there are still some grey areas. In order therefore, to be absolutely certain that time will start to count at the earliest opportunity, if there is any doubt as to the validity of the original notice the master should issue a further notice of readiness.
LAYTIME
"Laytime" is the term used to refer to the time allowed to the charterers to load/discharge cargo in return for payment of freight to the owners. If the charterers are unable to load/discharge cargo within this allowed period, they will be obliged to pay demurrage (liquidated damages for break of contract) or detention (unliquidated damages for breach of contract) to compensate the owners for their loss of use of the vessel. Naturally, most charterparties contain provisions which suspend the running of laytime and/or demurrage in certain circumstances as may have been agreed between the parties. In addition, neither laytime nor demurrage will run if the loss of time is due to a breach on the owners’ part.
It is clearly important to determine when laytime commences since this is the key to the division of responsibility for the time spent at the load and/or discharge port. Most charterparties require the owners to serve a notice of readiness at load or discharge port stating that the vessel is ready in all respects for cargo operations. Whilst the owners are also usually required to serve various approximate and definite notices of expected arrival at load or discharge port to enable the charterers to make all necessary arrangement in time, the notice of readiness constitutes the contractual step which is required to trigger the commencement of laytime. Due to this, charterparties usually contain provisions which stipulate a) when notice of readiness may be contractually served and b) when laytime commences once notice of readiness has been validly served (often a set period after tender of the notice of readiness, although commencement of laytime may be further suspended to make allowance for weekends and other periods when the port is not operative).
Requirements for a valid notice of readiness to be served:
1.     The vessel is an arrived vessel
2.     The vessel is ready to receive or discharge the cargo
3.     The notice of readiness is tendered to and received by the proper person according to the charterparty
4.     The notice of readiness is tendered in a contractual way
5.     The notice of readiness is tendered at a time that is allowed by the charterparty.

a) "Arrived ship"

Notice of readiness cannot be validly served before the vessel qualifies as an "arrived ship". To be an "arrived ship", the vessel must have reached the place within the port where notice of readiness may be served. This place is specified, expressly or impliedly, by the charterparty. Under a port charterparty, the vessel must reach the place where vessels usually wait within the port unless, of course, she is able to proceed directly to the load/discharge berth in which case notice of readiness may be tendered as soon as she enters the port. Under a berth charterparty, the vessel must reach the nominated load/discharge berth. These basic propositions may be varied by the inclusion of specific provisions such as "whether in berth or not" ("WIBON") or "whether in port or not" ("WIPON"), although the meaning of the latter phrase has not yet been determined by the Courts.

b) "WIBON"/"WIPON" provisions

The effect of a "WIBON" provision on the tender of notice of readiness under a berth charterparty was considered by the House of Lords in the "Kyzikos"¹. The Kyzikos had been fixed to carry a cargo of steel and/or steel products from Italy to Houston. The charter was on the Gencon form and provided, inter alia, as follows: "Discharging port or place – 1/2 safe always afloat, always accessible berth(s) each port …. Time lost in waiting for berth to count as laytime …. Wipon/Wibon/Wifpon/ Wccon." The vessel arrived at Houston to discharge. When notice of readiness was tendered, and at all material times thereafter, the berth was available. However, the vessel could not proceed to the berth for three days because fog had closed the pilot station. The owners argued that, by virtue of the "WIBON" provision in the charterparty, a valid notice of readiness could be tendered as soon as the vessel arrived at the customary waiting place within the port of Houston and that the "WIBON" provision effectively converted the charterparty into a port charterparty. The charterers argued that, at most, the phrase had the effect of allowing a valid notice of readiness to be tendered at the customary waiting place if the nominated berth was unavailable due to congestion and not if it was available but could not be reached for some other reason.
The House of Lords conducted an extensive review of the relevant authorities and observed that the argument that a "WIBON" provision converted a port charterparty into a berth charterparty was based upon the following passage from the judgement of Roskill L.J. in the "Joanna Oldendorf" :
"The phrase "whether in berth or not" was designed to convert a berth charterparty into a port charterparty and to ensure that under a berth charterparty Notice of Readiness could be given as soon as the ship had arrived within the commercial area of the port concerned so that laytime would start to run on its expiry. It has no proper place in a port charterparty".
The House of Lords felt, however, that these observations applied only if no berth was available for the vessel on her arrival at the port and not if a berth was available but the vessel was prevented from proceeding to it by bad weather. The long line of authority on the use of the phrase "WIBON" in berth charterparties dealt exclusively with the problem of congestion in ports, and not with bad weather preventing the vessel from proceeding to a vacant berth.
On this basis, The House of Lords held that the phrase had for a long time been treated as shorthand for "whether in berth (a berth being available) or not in berth (a berth not being available).
As indicated above, the "WIPON" provision does not appear to have been tested in the Courts. It seems reasonable to suppose, nevertheless, that this will be interpreted in a similar fashion so as to allow notice of readiness to be tendered as soon as the vessel reaches the customary waiting place for the port in the case of congestion within the port even if this is outside port limits.

c) "Ready in all respects"

Even if the vessel has reached the place within the port which is required by the charterparty, notice of readiness cannot be served unless she is also physically and legally ready in all respects to load or discharge the cargo. It is possible to accelerate the tender of a valid notice of readiness by the inclusion of a "whether customs cleared or not" ("WCCON") or a "whether in free pratique or not" ("WIFPON") provision.

Tender of notice of readiness before the vessel is an arrived ship and/or ready in all respects.

In the "Mexico I"³  , the English Court of Appeal reaffirmed the proposition that a notice of readiness, which is invalid when tendered because the vessel is not an arrived ship and/or ready to load or discharge, does not automatically become valid when these requirements are subsequently satisfied.
The "Mexico I" was chartered to carry a part cargo of 5,000 tonnes of bagged maize to Angola with the owners retaining the right to complete with other cargo. The maize cargo was partially overstowed by the owners’ own cargo and 500 tonnes of alubia beans which they had agreed to carry for the charterers under a separate contract. The ship arrived at the discharge port on 20th January and tendered notice of readiness the following day by telex, although the maize cargo was not totally freed from overstowed cargo until 1025 hours on 6th February. Discharge of the maize cargo did not begin until 1435 hours on 19th February. The owners conceded that the notice of readiness was defective when tendered, but argued that it automatically triggered laytime when the ship subsequently became ready to discharge the maize cargo at 1025 hours on 6th February. The Court of Appeal disagreed, holding that the master should have tendered a fresh, valid notice at that time to start laytime running, and that an invalid notice of readiness could not operate as a delayed-action device to trigger laytime.
The owners also argued that the charterers were bound to acknowledge that the invalid notice of readiness triggered laytime as soon as the ship became ready to discharge, because they had accepted the invalid notice. This argument was based upon the following alternative propositions:
a)     the charterers had expressly or impliedly surrendered their right to enforce the strict terms of the contract (waiver); or
b)    the charterers could not rely on the strict terms of the contract because these terms had been varied by agreement of the parties, as evidenced by a mutual course of dealing (variation of contract); or
c)     the charterers were estopped from enforcing the strict terms of the contract because both parties had acted in reliance upon a mutually shared assumption that their legal relationship operated in a different manner (estoppel by convention).
The Court found that the charterers had initially accepted the invalid notice of readiness only because they had relied upon the master’s implied assurance that the ship was ready to discharge the maize cargo. The Court also found that the charterers had not expressly or impliedly accepted that laytime began once the ship was ready to discharge the maize cargo. Thus, none of the grounds put forward by the owners was established. The Court did not, however, have to decide when laytime commenced because the charterers conceded that it had commenced as soon as discharge commenced. If the charterers had not made this concession, the Court might have decided that, in the absence of a fresh valid notice of readiness being tendered by the owners, laytime had never commenced.
The decision in "The Mexico I" was applied by the English Commercial Court in the "Agamemnon"4. The "Agamemnon" was chartered on the Gencon form for a voyage from one good and safe berth Baton Rouge to one good and safe berth Brisbane. The relevant terms of the charterparty were as follows:
"Time lost in waiting for berth to count as loading or discharging time .…" (clause 8);
"If the loading/discharging berth is not available on vessel’s arrival at or off the port of loading/discharging or so near thereto as she may be permitted to approach, the vessel shall be entitled to give notice of readiness on arrival there with the effect that laytime counts as if she were in berth and in all respects ready for loading/discharging .…" (clause 32) and
"Time to count whether in berth or not, whether notice accepted or not .…" (clause 33)
The master gave notice of readiness at the South West Pass, which was a customary waiting area for vessels wishing to enter the Mississippi river to proceed to one of the up river ports. Baton Rouge has its own anchorage is abut 170 miles from the South West Pass. The Court of Appeal held that a notice of readiness given before the vessel arrived at the Baton Rouge anchorage was not a valid notice and the subsequent arrival of the vessel at the Baton Rouge anchorage could not validate it.

Tender of notice of readiness at a non-contractual time when the vessel is an arrived ship and ready in all respects

As indicated above, voyage charterparties frequently provide that notice of readiness must be tendered within office hours or some other specified period. It is also common for masters to tender notice of readiness on arrival even if this means that the notice of readiness is tendered outside the period specified in the governing charterparty. In the "Petr Schmidt"5 the English Court of Appeal had an opportunity to consider the validity of a notice of readiness tendered outside the hours stipulated by the charter at a time when the vessel was ready in all respects and in the place provided for by the charterparty. The "Petr Schmidt" was chartered on an amended Asbatankvoy form charterparty. Clause 30 provided that "notice of readiness at loading and discharging port is to be tendered within 06.00 and 17.00 hrs. local time". Clause 6 of the charterparty provided, inter alia, that "laytime …. shall commence upon the expiration of six (6) hours after receipt of such notice or upon the vessel’s arrival in berth .… whichever first occurs". The master tendered notice of readiness at the load port and both discharge ports outside the period specified in clause 30. On each occasion, the vessel was an arrived ship and was physically and legally ready to load or discharge.
The Court of Appeal held that a notice of readiness which is tendered at a non-contractual time in respect of a vessel which is an arrived ship and is in all respects ready to load or discharge is valid. However, the Court also ruled that, although valid, such a notice of readiness could only become effective to trigger the commencement of laytime under clause 6 at the earliest moment it could have been contractually tendered under clause 30.

Conflict between notice of readiness provisions and "reachable on arrival" clauses in berth charterparties

In the "Laura Prima"6, the House of Lords considered the meaning of the words "reachable on arrival" in the context of a charterparty on the Exxonvoy 1969 form. The vessel was chartered for a voyage from one safe berth in Libya to two safe ports in Italy. The charterparty provided, inter alia, as follows:
"6. Notice of readiness. Upon arrival at customary anchorage at each port of loading .… the master .… shall give the charterer .… notice .… that the vessel is ready to load .… cargo, berth or no berth, and laytime .… shall commence upon the expiration of 6 hours after receipt of such notice or upon the vessel’s arrival in berth whichever first occurs. However, where delay is caused to vessel getting into berth and after giving notice of readiness for any reason over which charterers has no control, such delay shall not count as used laytime."
and
"9. Safe berthing – shifting. The vessel shall load .… any safe place or wharf, or along side vessels .… reachable on her arrival, which shall be designated and procured by the Charterer .…"
The vessel arrived at her loading place in Libya and tendered notice of readiness but was unable to proceed to a loading berth since all possible berths were occupied by other vessels. This remained the situation for almost two weeks. The charterers sought to rely on clause 6 to prevent the running of laytime on the grounds that the delay in berthing was beyond their control. The owners countered this argument by pointing out that the charterers were in breach of clause 9 as they had not procured a berth which was reachable on arrival of the vessel. The House of Lords held that clause 9 did prevail over clause 6 and that clause 9 therefore required the charterers to nominate a berth which was reachable on the vessel’s arrival. If the vessel was unable to proceed to the berth on arrival charterers were in breach of their obligations under the charterparty and could not rely on the exception to laytime contained in clause 6. In delivering his judgment, Lord Brandon said;
"Reachable on arrival" is a well-known phrase and means precisely what it says. If a berth cannot be reached on arrival, the warranty is broken unless there is some relevant protecting exception … The berth is required to have two characteristics: it has to be safe and it has also to be reachable on arrival."
"The Laura Prima" was later applied in the "Sea Queen"7(berth not reachable due to unavailability of tugs) and the "Fjordaas"8 (berth unavailable due to bad weather). The fact that the principle established by the Laura Prima applies when a berth is not reachable on arrival for any reason and not just congestion was thus affirmed by these two judgments. This was clearly demonstrated by London arbitration No. 16/98 (LMLN ). In this case, the vessel was chartered on an amended Asbatankvoy form charterparty which contained clauses 6 and 9 which were identical to those quoted above from the Laura Prima charterparty. Additional clause 13 also provided as follows:
"Suspension of Running Time Clause: Time shall not count as laytime, or if on demurrage as demurrage, when spent or lost: (a) for and on an inward passage moving from anchorage to first berth, including awaiting tugs, pilot .… until the vessel is securely moored at the berth .…"
When the vessel arrived at the discharge port on 31st December, the berth to which she had been consigned was vacant. On the previous day, another vessel chartered by the same charterers had arrived at the port and they wished her to berth first for commercial reasons. Bad weather initially prevented the other vessel from berthing on 31st December and she was unable to berth as no tugs were available due to holidays until 2nd January. The other vessel berthed on 2nd January and sailed on 3rd January. The first vessel then berthed. The Tribunal was asked to consider if time ran from 31st December or from 2nd January. The charterers contended that a berth had been available upon arrival and that the proximate cause preventing berthing was not congestion (as in the "Laura Prima") but adverse weather and the unavailability of tugs. The Tribunal held that the "Laura Prima" applied not only when congestion meant that the berth was not reachable on arrival but also when the berth was not reachable on arrival for any other reason (as in the "Sea Queen" and the "Fjordaas"). Accordingly, the owners’ claim succeeded in full.
