Tamina's winch

Injuries during mooring operations are often horrific and too commonly fatal. The briefest moment of inattention, uncertainty or confusion can result in tragedy. In the case of an incident aboard m/v Tamina a second officer’s was spared because of the prompt action of crew and the proximity of an ambulance but he lost a leg.

The Swedish Transport Agency report on the 7 July 2010 incident says: “…the bunker vessel Tamina departed from Dalanäs, Gothenburg. The destination was Masthuggskajen about 1.6 nautical miles away where the vessel berthed at the platform below the loading ramps for the high speed craft Stena Carisma.
The crew of the vessel consisted of Master, Chief Officer, second officer and two able seamen. In addition to the regular crew members there were also two cadets on board.

Mooring the vessel was routine work on board and was usually done several times per day. The vessel had mooring winches installed forward and aft of the vessel. The procedures were to make fast the lines ashore, take up the slack with the winches and then secure the lines on the bollards on board.

Before arrival at Masthuggskajen the second officer came out on deck on his time off. He wanted to assist in the mooring work and positioned himself at the winch aft of the forecastle on the starboard side. He had been onboard for one week and had done the mooring at Masthuggskajen a couple of days earlier. This was, however, the first time he used the winch aft of the forecastle.

One of the cadets and an able seaman were standing at the forecastle. As the Master maneuvered the vessel alongside the platform at the ramps the other cadet climbed ashore to receive and make the lines fast. The platform was short and the vessel got a long overhang in the forward making the spring line quite long. The breast line was lead out from the winch were the second officer was standing. It went from the winch via a roller on top of the railing to a bollard aft of the winch. From the bollard the line was lead approximately 10-15 meters aft, in line with the platform, and then ashore.

The breast line was lead in a tight angle between the winch and the bollards on board with the roller in the center. As the line was sent ashore and made fast the second officer was standing at the winch. According to the second officer he heard the Master calling something from the bridge and turned around so his back was facing the railing. He now had the maneuvering handle of the winch in front of him and was not sure whether to slack out or heave on the line. He then started to heave on the line by pulling the handle.

After securing the spring line the cadet on the forecastle was about to go aft to assist with the other lines when he heard a cracking sound. He looked towards the place where the second officer was standing and saw the roller being torn off its fitting. The second officer was hit by the line as it came loose. He fell and instinctively held on to the maneuvering handle. This caused the winch to continue heaving and as a result he was caught with his legs in it before he released the handle.
