Caught in a bight
(Edited from official Australian Transportation Safety Bureau (ATSB) 2014-005
A vessel that had been assisted by a tug was preparing
to let go the tow. In preparation for letting go, seaman 1
ran the messenger line over the drum end of the mooring
winch, while seaman 2 operated the winch to pull about two
5. metres of tow line inboard. The second mate wrapped
the rope stopper around the main tow line while the
messenger line was taken off the drum end and the eye of the
tow line taken off the mooring bitts. The messenger
line was then put around the forward post of the mooring
10. bitts to assist with the controlled lowering of the tow
line.
On board the tug, a crewmember was standing on deck near
the winch ready to guide the tow line onto the winch drum.
Another crewmember was at the remote winch controls inside
15. at the port bridge console. The crewmember controlling the
winch waited until he saw the tow line being lowered before
he started heaving in. As the tow line was retrieved, seaman
2's right leg somehow became entangled in the messenger
line. He was then dragged about four metres across the deck
20. and into the rollers of the fairlead. When his legs entered
the fairlead the messenger line came under tension and it
severed the seaman's right foot.
Both crew on the tug had seen the messenger line go tight
and the crewmember at the winch control stopped heaving. The
25. assisted vessel's second mate ran to the ship's rail and
signalled to slacken the line. Medical assistance from
ashore was quickly requested and the victim was transported
to hospital for treatment.
