Hand injury while using manual torque tool
A deck engineer was torquing Grayloc clamp bolts connecting the gooseneck connector onto the second end of a flexible, using a manual torque wrench with a force multiplier attached. A project engineer was in the moonpool area to verify the torque settings on the wrench, as stipulated in the task plan. The project engineer stepped in to assist the deck engineer and they began torquing the bolts together. During the torquing of the last bolt, the project engineer placed his left hand on the reaction bar of the force multiplier as torque was being applied. His hand slipped and was trapped between the reaction bar and the gooseneck causing a hand injury.
Loss of redundancy in diving bell launch and recovery (LARS) PLC system
During a vessel transit to an offshore field, Dive Technicians on a routine walkaround noticed an alarm from the LARS for the dive bells. Investigation indicated loss of automatic (LARS) PLC redundancy caused by failure of one of the PLC fibre optic processor synchronisation links. This resulted in the loss of normal operation and increased the risk of single point failure of the dive bell Launch and Recovery System (LARS), so the decision was taken to return to port. No-one was injured. The divers in the saturation chambers were not affected by the system fault.
Hand injury in medical airlock
An LST (Life Support Technician) suffered a finger injury whilst operating the medical airlock (“Med-lock”) on a dive chamber. The LST (Life Support Technician) was closing the Med-lock door but was unable to rotate the door to the fully closed position, indicating that the hatch needed to rotate further clockwise. The LST attempted to rotate the hatch counterclockwise in order to be able to open the door and inspect it. The Med-lock was stiff to rotate. For leverage to assist with rotating the Med-lock, the LST placed his hand on the flat bars that brace the operating wheel. The hatch moved suddenly and because his hands were on the brace and not on the wheel itself, his hand got pinched between the brace and the Med-lock door hinge plate, causing an injury.
Painter line snapped and hit crew member in the face
A painter line snapped during towing operations, and the flying end struck a worker in the face. The worker was wearing full PPE (helmet and safety glasses) and had it not been for the helmet and safety glasses there could have been a more serious injury. The safety glasses were destroyed.
