ATB Delivered by Alabama Shipyard

Alabama Shipyard, Inc. delivered Nicole Leigh Reinauer and RTC 135, an articulated tug/barge (ATB) unit, built for Reinauer Transportation Companies of New York. Alabama Shipyard designed the 135,000 barrel, 460-ft. double-hulled barge in compliance with OPA 90 regulations. Bob Hill of Ocean Tug and Barge Engineering designed the 7,200 hp twin-screw 124 ft. tug, built by Alabama Shipyard's sister company, Atlantic Marine. The ocean-going tug/barge unit features a patented Intercon tug/barge coupler system designed and built by Intercontinental Engineering and Manufacturing Corporation of Kansas City. The system consists of two independently mounted gear-driven ram assemblies which connect the tug and barge. The connection is transversely rigid and mechanically locked, resulting in a vessel that handles like a commercial ship. The tug pushes the barge, resulting in speed advantages of 35 percent or more, compared to traditionally towed barges. The double-hulled barge design mated to a tug with redundant propulsion provides safeguards for the marine environment. Additionally, the ABS-classed vessels can be engaged and disengaged without crew on deck. Vessel Specifications Tug Nicole Leigh Reinauer Length: 124 ft. Beam: 40 ft. Hull Depth: 22 ft.
