At 1303 local time on December 19, 2020, the no. 3 diesel generator engine aboard the Ocean Intervention suffered a mechanical failure while the offshore supply vessel was anchored off Honolulu, Hawaii. The failure led to the ejection of components from the engine and resulted in a fire in the engine room. The crew isolated the fire before it could spread throughout the vessel. No pollution or injury to the 16 crewmembers on board was reported. Damage to the Ocean Intervention totaled $3,046,624.
We determined that the probable cause of the diesel generator engine failure aboard the offshore supply vessel Ocean Intervention was a cylinder’s connecting rod bearing adhering to the crankshaft, which led to the ejection of the connecting rod and catastrophic damage to the engine.
