5/20/2014: USCG & BSEE Joint safety alert – Dynamic positioning system failures

The U.S. Coast Guard and the Bureau of Safety and Environmental Enforcement issued a joint safety alert addressing a dynamic positioning incident on a vessel resulting in a loss of position while conducting a critical Outer Continental Shelf activity. An equipment failure, an operational error and multiple failure modes – not identified in the vessel’s Failure Modes and Effects Analysis – combined to produce the loss of position.

Consequences such as personal injury, environmental pollution or catastrophic damage were averted because of the successful actions taken by the crew, who performed an emergency disconnect from the well in accordance with established procedures.

The Coast Guard and BSEE are issuing this joint safety alert because we share jurisdiction over vessels that perform this type of Outer Continental Shelf activity and wish to highlight the interaction between a vessel’s Safety Management System and a leaseholder’s Safety and Environmental Management System.
