A UK marine aggregate dredger was undertaking routine mooring operations. The injured party (IP) was part of the forward mooring crew, and as he threw the heaving line (a lighter weight rope connected to the ships mooring ropes) to the shore staff on the quayside 7-10 metres away, he lost balance and fell in an uncontrolled manner. This resulted in his upper leg and hip to come into contact with the fairlead reinforcements and the deck.
The IP remained immobile while mooring operations were completed, and medical assistance was requested. The IP was removed by ambulance and taken to hospital, where he was treated for a fracture to his upper leg.
Following the incident, the investigation determined that prior to joining the company six months earlier, the IP had an underlying, but unreported, medical condition (a frozen right shoulder) that resulted in him using his non-dominant left arm to throw the mooring line. Neither the company or captains were made aware of the medical condition, although some members of the crew had noticed that the IP appeared to have restricted movement of his right arm.
At the time, the company did not have a process for formally recording any medical issues/conditions a seafarer may have when joining or during time on ship
