The U.Ok. Marine Accident Investigation Department (MAIB) has revealed its report on an August 30, 2021 incident wherein the chief officer of a common cargo ship, managed by V.Ships Ship Administration (India), was fatally injured when he was struck by a tensioned mooring line when it sprang out of an open curler fairlead.

The accident occurred on the Kavkaz anchorage in Russia when the Isle of Man registered open hatch common cargo ship Teal Bay was moored alongside an anchored bulk provider, which was appearing as a grain storage vessel, finishing up ship-to-ship (STS) loading operations.

The mooring association consisted of three head traces, three stern traces, two ahead springs and two aft springs; all traces belonged to Teal Bay, which was loading grain from the bulker and it was being moved ahead by tensioning the aft spring to permit loading to be accomplished.

In the course of the loading operation, Teal Bay’s mooring traces had developed an upward lead as a result of change in freeboard between the 2 vessels and, as the road was tensioned to maneuver Teal Bay, its upward lead angle turned too nice for the open fairlead to include it.

As ever, the complete MAIB report deserves studying, not least as a result of it offers perception into the true life situations beneath which seafarers truly work. Its essential barebones conclusions are:

  • Teal Bay’s C/O was struck on the top and fatally injured by a tensioned mooring line when it sprang out of a curler fairlead and snapped tight.
  • The mooring line sprang free as a result of the fairlead in use was open and the traces had developed a hazardous upward lead throughout STS cargo operations because the distinction between the vessels’ freeboard elevated.
  • Main two traces by way of the identical fairlead restricted the house out there and virtually actually contributed to the lack of spring line 1 containment.
  • The variety of crew assigned to hold out the warping operation was inadequate and virtually actually influenced the C/O’s determination, which went unchallenged, to face in a hazardous space.
  • There was inadequate planning for each the mooring and the warping; this occurred as a result of, for each evolutions, there was a scarcity of time out there to plan and the crew was unfamiliar with STS bulk cargo operations.
  • Regardless of the crew’s efforts and the help of a tug, it took over two hours for the casualty to be seen by a medical skilled. Given the severity of his accidents, it’s unknown whether or not the delays within the C/O receiving medical consideration had any bearing on his demise; nonetheless, the dearth of coordination by the events concerned in organizing the medical response created delays that lessened his probabilities of survival.
  • The investigation discovered that the usage of an open fairlead was inappropriate in the course of the switch of cargo the place a freeboard differential created the hazard of an upward lead on the mooring traces. The chief officer was struck as a result of he was standing in a hazardous space near a tensioned mooring line and the operation to maneuver Teal Bay ahead was tried with inadequate crew and had not been threat assessed.

The MAIB carried out the investigation on behalf of the Isle of Man Ship Registry in accordance with the Memorandum of Understanding between the MAIB and the Pink Ensign Group Class 1 registries of Isle of Man, Cayman Islands, Bermuda and Gibraltar.
