Marine Safety Forum – Safety Flash 13-24
Issued: 18th June 2013 Subject: High Potential Near Miss during Cargo Operations
Whilst engaged in Cargo Operations alongside a Platform within the North Sea, a high potential Near Miss occurred which involved 2 AB’s, who were exposed to a potential crushing injury during back loading operations. Prior to entry into the 500metre zone, appropriate checks had been completed, standard communications during the operation were one AB had direct UHF communication with the Bridge, whilst the 2nd AB had direct VHF communication with the platform and crane driver. The weather was clear with the sea state approximately 2.5metres. Nearing the completion of backload operations, the crane driver had been advised by the Bridge Team to land a cargo unit in Bay 4 on the centreline of the vessel. The crane driver made several attempts to land this cargo unit, the descent and positioning attempts were made in an uncontrolled manner. On third landing, the deck crew approached the unit to unhook as they observed the bridle over the cargo unit, and the hook and wire landed on deck. To approach the unit at this time is normal practice for the deck crew; video footage of this incident clearly shows that this cargo had been on the deck with the bridle over the cargo unit for an adequate time for the deck crew to assume this was landed and safe to approach. The deck crew did not see the swivel moving outboard or then back inboard but were focused on the deck height length of wire which was more or less stationary. As one deck member went for the wire and the other went to unhook, the bridle rapidly ascended and the cargo came off the deck and swung. At this point the deck crew ran forward between back loaded cargo to escape the rising unit and avoid a potentially significant injury.
Although Communications had been established, it was noted during investigation that the deck crew had reported that communications with the crane driver were poor
The option to Stop the Job was not identified, nor was the erratic Crane operations reported
Deck Crew did not attempt to contact the Crane Driver to confirm cargo was safely landed, after 3rd
attempt to land.
Crane Driver did not make any attempt to warn the deck crew by radio communications or sound signalling
The vessel’s movement was slight and the location of the cargo was at frame 60 on the centre line where pitch and roll have very little effect. The vessel was heaving about 1-1.5m which does not account for the rapid ascent of the cargo unit, therefore it is identified that the lift was heaved after the deck crew had approached it.
From Video footage, it is clear that the cargo was landed and had been moved into a suitable position, with adequate time for the deck crew to approach
The crane driver stated that he did not see that the deck crew had approached the cargo unit, and repositioned the cargo unit into Bay 4.
Deck crew were attired in high visibility jackets and hat covers and the deck was well illuminated
Due to cargo operations continuing, the Deck crew did not raise this as a concern or near miss incident to the installation at the time.
Due to the location on the deck, the Bridge did not witness this incident, however had this been witnessed or reported a Time out for Safety would have been called and the Platform informed.
