The 9,280 hp Ocean Relience is the first of two tugs built by Marinette Marine Corp. for Vessel Management Services (VMS), a Crowley Maritime Co. The vessel is intended to operate as a tug/barge unit in conjunction with the 155,000-barrel tank barge 550-3. Construction engineering for the barge was also accomplished by Schuller & Allan LLC. The connection device is an Intercon Coupling system. Earlier this year, Vessel Management Services, Inc. christened the first of four Articulated Tug-Barge (ATB) tank vessels that the company took in 2002, the 9,280 hp-tug Sea Reliance and 155,000-barrel barge 550-1, built by Halter Marine. The barge 550-1 was built at Halter's Port Bienville shipyard in Pearlington, Miss., and the Sea Reliance at its Moss Point Marine shipyard, in Escatawpa, Miss.
