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.
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.
A small multi-purpose vessel crewed by a Master, an officer, and two ratings was up-bound in a river system. The OOW tried to make a course alteration to starboard and noticed that the rudder was not responding normally.
