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.
