There are no doubt scores of 15 to 20-year-old 180-ft. supply boats that still have years of useful life… if renovated by skillful and creative marine engineers. That is what ENSCO Marine Company, Broussard, La. has done with a six-pack of vintage supply boats whose day rates and utilization had slipped due to age and limited carrying capacity for their size. ENSCO Marine is a division of ENSCO International, a Dallas, Texas-based drilling contractor who owns and operates 56 drilling rigs in the Gulf of Mexico, the North Sea, Asia Pacific and South America. ENSCO Marine operates 23 offshore supply boats and five anchor handling tugs.
