Case Study: Pre-Departure Checks Lead To Maintenance Interval Change
A tanker had finished a discharging operation and crew were carrying out pre-departure checks and preparations while awaiting the pilot.

A bulk carrier was in port. Following recommendations from a surveyor, the holds were to be painted to render them acceptable for grain transport.
The pilot arrived on the bridge and asked for ‘full ahead’. As the ship passed through the port entrance at seven knots the pilot ordered ‘slow ahead’ and a berthing tug was made fast forward.
The vessel while inbound to a port in darkness, responded to the port rudder, the deviation to the left of the planned track increased, activating the off-track alert on the ECDIS. The alarm was acknowledged but the information was not passed on to the other members of the bridge team.
When the OOW saw that he was abreast of the red marker, he moved the autopilot control stick a few ‘clicks’ to port. The AIS signals show that the vessel’s course changed by 6° to port during the final 31 seconds before the grounding.
Shortly after leaving port, the ship encountered strong winds and waves. Rolling heavily, the ship developed a list of about 25° to starboard. After about an hour the list increased to 30°.
A tanker had discharged cargo and was outbound under pilotage in a restricted waterway when an oil mist detector alarm for the main engine sounded, which caused the engine to shut down.
Staff on an up-bound tanker in a river waterway decided to anchor the vessel just below the lock to wait for traffic ahead to clear. While it was anchoring the vessel lost propulsion.
A small coastal trader was underway in darkness and calm seas at a speed of almost 8kt. There was a change of officers on the bridge. At the time, the vessel was on autopilot ‘track mode’ steering.
