NPD Issues Safety Notice Following Gyda Accident

Recently, a person was killed in an accident during a lifting operation on the Gyda Platform located on the Norwegian continental shelf. The accident is still under investigation, but the NPD thinks it is necessary to relate some of the incidents that led to the accident as this may help in preventing similar accidents in the future.

Two chemical pods had been stacked on top of each other. Preparations were being made to move the upper pod onto the deck by means of the crane. During the lifting operation, the pendant, which was not connected to the pod slings, got stuck between the pod's framework and the pod. By lifting the pendant, it snagged the frame causing the pod to slide, and it fell down and hit a person.

Pods of the type shown (see picture) have proven to be unstable when stacked on top of each other. The retaining mechanism (see circle) appears to be insufficient to prevent sliding when a force is applied to the pod.

Special attention should be paid to stacking of equipment. Only equipment specially designed for safe stacking offshore should be stacked. Chains or wire slings should be long enough to be hooked on at deck level.
