TSB Canada issued an investigation report on the collision of the bulk carriers Golden Cecilie and Green K-Max 1 in the Plumper Sound, British Columbia, in March 2020. The Golden Cecilie suffered dragging anchor due to heavy winds, the report reveals, stressing that the crew did not follow established procedures to ready the vessel for impending adverse weather conditions.
The incident
On 30
March 2020, the bulk carrier Golden Cecilie was anchored at Anchorage C in
Plumper Sound, British Columbia, with 20 people onboard, when it collided with
the bulk carrier Green K-Max 1 anchored at Anchorage B, after reporting a dragging anchor due to gusting wind.
Following
the collision, both vessels’ anchor chains became entangled. With the direction
of a pilot on each vessel, and the assistance of two tugs, the anchor chains
were disentangled and the two vessels returned under their own power to their
respective anchorages and were secured in place. There were no injuries or
pollution reported, but both vessels sustained damage to their hulls as a
result of the incident.
Key findings
The
Golden Cecilie had an SMS manual that included guidance and recommendations on
how to mitigate the risk of dragging anchor.
The
investigation established that the crew did not collect the daily local weather
forecast for the day of occurrence from the VHF radio, weather fax, medium
frequency-high frequency broadcast, nor did the crew obtain an up-to-date
weather warning from local authorities, such as Environment and Climate Change
Canada (ECCC) or Marine Communication and Traffic Services (MCTS). As a
consequence the crew did not follow established procedures to ready the vessel
and crew for impending adverse weather conditions. As well, factors that impact
dragging an anchor had not been taken into consideration as per the SMS, and
the emergency preparedness to respond to adverse weather was inadequate, ...the
report reads.
Actions taken
Following the occurrence, the Golden Cecilie’s operator took the
following safety action:
- The
anchoring and anchor watch checklist was amended on 01 May 2020
to indicate that the master should be informed immediately if the
barometric pressure drops by 3 mb during watch or if the wind speed
exceeds 21 knots (force 5 on the Beaufort scale). In such
circumstances, the engines are to be placed on standby and the deck watch
is to monitor the anchor position.
- The
checklist was also amended to specifically indicate the engine notice
period as per the master’s instruction. A notice was sent to the vessels
informing them that they should be documenting the engine notice period,
the state of readiness, and the position of the second anchor in the
bridge log book.
- A
“Safety Flash” bulletin was circulated to all vessel crew members
stressing the importance of proper anchor watches and compliance with the
SMS.
- Bridge
resource management refresher training was arranged for bridge watch
officers.
Safety messages
When vessels are at anchor, crews need to:
- collect
weather forecasts from all available sources in a timely manner;
- be
aware of the risk factors that can lead to dragging anchor, in particular
excessive freeboard and inadequate ballasting; and
- ensure
that the main engines, anchors, and deck machinery are ready so that
corrective action can be taken at the first sign of dragging anchor.
Between January
2015 and March 2020, a total of 102 dragging anchor occurrences along the BC
coastline were reported to MCTS.
