We have received information concerning part of the manufacturer’s name plate, weighing 250 g, falling off of an offshore crane on an offshore installation, landing 21 m below on an over-side scaffold at deck level.

There was no-one on the scaffold at the time and no work was ongoing in the immediate vicinity.

The following initial findings were identified:

  • The sign had been installed onto handrails on the crane’s ‘A’ frame since the unit’s construction.
  • Failure of the sign had occurred through the fixing bolt hole, due to metal fatigue which, in turn, was caused by the operational vibration of the handrail.
  • The sign was in poor condition and had a number of cracks throughout its length. A similar sign on the opposite side of the crane appeared to be in good condition.

The company involved has removed similarly installed signs from other cranes.
