The deck team undertook the greasing of the aft mooring winches.
Using a grease gun, an O/S began greasing a winch. The O/S was
holding the hose of the grease gun with his right hand while resting his
left hand on the groove where the winch gear is engaged.
The Bosun, unaware that the OS was resting his left hand on the
groove of the winch engagement, ordered another seaman to turn
the winch slowly to maximize the greasing effect. Suddenly, the OS
using the grease gun shouted ‘Stop, stop, stop’. The winch was stopped
immediately, but not before the gear had seriously wounded his
hand. The victim was treated for deep lacerations in the hospital and
repatriated, being declared unfit for work for 14 days.
