VESSEL REVIEW | Green Wave – Plimsoll Marine’s heavy duty pusher tug built for Mississippi River sailings
TUG AND SALVAGE WEEK
Shipbuilder Blakeley BoatWorks of Mobile, Alabama, has delivered a new inland pusher tug to the Cooper Group of Companies. Named Green Wave, the vessel will be owned by Cooper subsidiary Plimsoll Marine and will be operated primarily on the Lower Mississippi River.
Designed by Farrell and Norton Naval Architects in compliance to US Coast Guard Subchapter M requirements, the new tug has a length of 70 feet (21.3 metres), a beam of 28 feet (8.5 metres), and two Caterpillar C32 diesel engines that each produce 800 hp (596 kW). The EPA Tier III main engines drive a pair of Southeastern Propeller four-blade, stainless steel propellers via Twin Disc MGX5222 gearboxes. Hydra Force meanwhile supplied the steering system for the two main and four flanking rudders as well as a pair of Quincy reciprocating air compressors
Electrical power is drawn from two Caterpillar C4.4 EPA Tier III generator sets. Ventilation fans were provided by Donovan Marine while Schuyler Maritime supplied varying sizes of rubber fendering around the perimeter of the vessel and push knees.
Stone Construction provided a Mitsubishi split-duct HVAC system in all interior spaces with Blakeley BoatWorks providing all custom woodwork and interior finishes. Bozant supplied rubber-framed windows and Donovan Marine supplied a pair of Patterson Manufacturing deck winches. Blakeley BoatWorks installed all electronics, communications, and an alarm system.
Green Wave has capacities of 22,000 gallons (83,279 litres) of fuel and 5,200 gallons (19,684 litres) of fresh water. The vessel is outfitted with four staterooms housing seven crewmen as well as three baths and a full galley arrangement.
