Thoma-Sea Building Cummins-Powered Z-Drive

Cummins Marine's recently introduced QSK60 engines are finding a ready market in the 2000 HP plus range in both Europe and North America. This spring the sale of two more QSK60s was announced for a Z-drive tug building at Thoma-Sea Boatbuilders in Houma Louisiana. Designed by well-know Louisiana-based naval architect Frank Basile's Entech and Associates Inc., the 104 by 36-foot boat will have a 17-foot moulded depth. Tankage provides for over 90,000 gallons of fuel, 10,000 gallons of potable water and 500 gallons of lube oil.

The twin Cummins KTA60 main engines.

The two Cummins QSK60 main engines will each produce 2200 continuous-duty horsepower at 1800 RPM. The engines will drive Rolls-Royce US 205 Z-drives. The drives have 2150 m/m propellers in nozzles. Ship power will be provided by two Cummins 6BT5.9 powered 75 kW generator sets. The Markey bow winch will handle 500 feet of 8-inch Spectra line. "We have gone with an electric winch on this boat," says Harley Marine representative Gregg Nelson, "As we understand that it has better auto-render recovery capabilities."

The crew who did the high quality woodwork and finishing of the vessel's interiors. From left to right; Jimmy Verret, Daryl Billot and Arnis Verret. All of these men learned their woodworking skills with the Cajun shipwrights along the Louisiana Bayous.

Accommodation will be provided for six crew members. Design speed for the vessel is 11 knots. When delivered in August of 2003 the boat will take up duties on the West Coast, where she will join other tractor and ship assist tugs in the Harley Marine Services subsidiary companies, Millennium and Starlight Marine. Company president Harley Franco explains that she will be assigned to one of several ports as required. Harley Marine Services, currently operates vessels in ship assist, tanker escort and ocean towing along the Pacific Coast from Long Beach California to Dutch Harbor Alaska.
