LIKELY CAUSE OF GULF ACCIDENT PINPOINTED
A compressor on a subcontractor work boat probably ignited a mixture of natural gas and liquid hydrocarbons expelled when an 18 in. riser pipe was purposely cut last year in the Gulf of Mexico. The resulting explosion killed seven persons and destroyed ARCO Oil & Gas Co.'s Platform B on South Pass Block 60. Those are the findings of a Minerals Management Service, U.S. Coast Guard, and Office of Pipe Line Safety investigation of the incident.
