An offshore windfarm Service Operation Vessel (SOV) was positioned at a wind turbine generator (WTG). Waves of 3m and a swell of 2.8m were being experienced but this was deemed acceptable.

Aft mooring lines un-spool from its drum and lost overboard. The investigation revealed that the drum control level had been left slightly in the release direction. The drum had then slowly un-spooled by itself after crew had left the aft mooring station.

The vessels nonetheless collided with a closing speed of approximately 15 knots. The tanker’s bow struck the FTV on the port side at an angle of 45 degrees.

A pipe-laying vessel was at anchor and maintenance was being done on the ‘J-Lay Tower’ (JLT) by a sub-contractor specialised in work at height.

A general cargo vessel was berthed and stevedores were preparing to unload logs from the holds, which had been opened several hours earlier.

A vessel was underway at sea and crew were undertaking normal maintenance. One person, assisted by another, was to replace a limit switch on the provisions crane.

A passenger vessel berthed and the crew was preparing to move the gangway from deck 2 to deck 1 to accommodate the tidal range, which was lower than at the last port.

During a safety walkaround on a vessel it was observed that several type C watertight doors were routinely kept open while underway.
