DYNAMIC POSITIONING SYSTEM FAILURES ON OFFSHORE SUPPLY VESSELS ENGAGED IN OIL AND GAS OPERATIONS IN THE U.S. OUTER CONTINENTAL SHELF

This Joint Safety Alert addresses a dynamic positioning (DP) incident involving an Offshore Supply Vessel (OSV) which resulted in a loss of position while conducting a critical Outer Continental Shelf (OCS) activity. The OSV was attached to a wellhead, lost position and severed the wellhead tree causing a lubricant release on the platform deck and to the environment. Immediately prior to the position loss, the OSV had multiple DP system alarms and failures, including loss of bow thruster and engine control. No attempt was made to identify or correct the causes of these failures and the operations continued.
