A member of a team of workers dismantling subsea emergency shutdown valves (ESDV) on deck was badly injured when hit by parts of a valve that were ejected with force.
The team had successfully and without any problems already dismantled three (3) valves / ESDV as per the plans for that night. As the last valve was being disconnected, the Grayloc connection between the jumper and valve, along with the gasket inside the line, was ejected with force. The ejected gasket hit one worker on the forehead, resulting in a bleeding wound. The injured person remained conscious throughout and was assisted to the medic for treatment. The worker was treated by the medic and received seventeen stitches to the wound.
