A recent Safety Flash by the International Marine Contractors Association (IMCA), focuses on an incident, in which, during launch testing of a lifeboat, a turnbuckle and shackle weighing 7kg fell 23m from the davit onto the boat, landing within a metre of a worker hooking up the falls at the lifeboat hatch.
T he worker was physically unharmed; there was some cosmetic damage to the lifeboat. 3 Inch Turnbuckle
There was a mechanical failure – the turnbuckle was of a “closed” design that did not allow visual inspection of the thread engagement through the buckle. The threaded end of this turnbuckle was just 13cm and had one thread securing it into the buckle (see location of nut in illustration) on the threaded end. The bottom end was lost at sea.
