In early November, the 93′ Patriot was tied up at Washburn & Doughty Associates in East Boothbay, Maine. Once sea trials were completed, a December delivery was expected to Marine Towingof Tampa LLC.
After building three 92’×32′ Z-drive tugs for the Tampa, Fla., tug operator — the Independent, the Freedom and the Liberty — this is the first 93’×38′ tug built for the company. Both the 92′ and the 93′ designs are from Washburn & Doughty.
Though the Patriot will be used primarily for ship assist services at the Port of Tampa and Port Manatee, the 93-footer’s additional beam and length give the tug ship-escorting capabilities.
Marine Towing’s 92′ tugs have limited firefighting systems, whereas the Patriot has a FiFi 1 rating with two FFS 1200 long-barrel monitors, each capable of putting out 5,284 gpm from a FFS model SFP 300×400 pump that’s powered by a 1,300-hp Caterpillar C32 engine. The hull’s exterior is protected by a deluge system.
“If there’s a project requiring a large firefighting system, they have it,” said Washburn & Doughty’s Bruce Washburn.
Another difference between the Patriot and Marine Towing’s 92-footers is the towing capability of the new tug with a JonRie 512 hydraulic towing winch on the stern with 2,100′ of soft line.
Up forward is a JonRie 220 double-drum hydraulic hawser winch with automatic recovery on each drum. Both drums carry 450′ of soft line.
A pair of 2,575-hp Caterpillar 3516B engines power Rolls-Royce US 205 Z-drives with 94″ stainless-steel propellers.
The Patriot has accommodations for six crewmen in four staterooms. Each stateroom has its own air-conditioning system. In the galley, “They went with high-end domestic appliances, primarily in the stove,” said Washburn.
The Patriot is Washburn & Doughty’s fourth 93-footer. Three more are under construction with another under contract. Three of the tugs are for Moran Towing Corp., and one is for McAllister Towing and Transportation.
Looking ahead, Washburn said he has gotten inquiries for a hybrid-powered design, and potential customers have also been asking about tugs powered with LNG. “We are at least at the sketchpad level of several different projects,” Washburn said.
