Summary
Investigation of Endurance’s loss of station keeping during wireline operations at Eugene Island 355A. Vessel movement severed the production tree through connected rigid pipework, causing an oil spill and deck damage without reported injuries. Suspected communications-tower interference and absent emergency disconnection are examined, alongside equipment-separation measures and proposed vessel evaluation procedures.
