Report of Investigation into grounding of MODU Kulluk

The U.S. Coast Guard has released the report of investigation into the circumstances surrounding the grounding of the mobile offshore drilling unit Kulluk on the eastern coast of Sitkalidak Island, Alaska, Dec. 31, 2012.

A series of events contributed to the causal factors that resulted in the grounding of the Kulluk, with the most significant factor being the inadequate assessment and management of risks associated with a complex vessel movement during the winter in the unique and challenging operating environment of Alaska.

Among the safety recommendations issued in the report is the recommendation that the U.S. Coast Guard Commandant partner with the Towing Safety Advisory Committee to establish a working group to draft and accept a task statement addressing, but not limited to, the issues raised by this marine casualty, the towage of mobile offshore drilling units in the arctic marine environment and several other concerns.

The Coast Guard reminds companies that safety and risk management need to be a priority when evaluating maritime evolutions to ensure responsible, safe and efficient operations. Professional mariners have a responsibility to ensure they manage and follow approved procedures for all maritime operations to prevent and mitigate potential incidents.

The report of investigation may be accessed on the U.S. Coast Guard Homeport Marine Casualty Reports website.
