Mooring near-miss: Lines break during un-docking operation

The Danish safety organisation Seahealth.dk has circulated a near miss incident in which lines parted during undocking operations. A vessel’s mooring lines (double braided synthetic fibre rope 65mm) were used as tug lines (two lines connected to one tug). When the vessel dropped off all the lines from the berth, the tug started pulling the vessel. After about three minutes the two lines parted. There were no crew standing in the area where the tug line was connected. There were no injuries and no damage to the vessel except for the two failed mooring lines.

It will be understood that the potential consequence of this incident could have been a fatality.

Investigation revealed that the mooring ropes bore no sign of damage prior to the incident, and had been in operation since delivery of the vessel in 2005. The same vessel had seven other mooring lines in use of that age.
