Bisso Towboat orders tug

Bisso Towboat Co., Inc., New Orleans, has signed an agreement with Main Iron Works, Inc., Houma, La. to begin construction on a new 4,300 HP reverse z-drive ship-assist tug.

The tug will measure 100 ft x 38 ft x 13.5 ft and will be powered by a pair of EMD 16-645E6 (EPA Compliantnt) main engines, producing 2,150 hp each at 900 RPM, driving Ulstein-Aquamaster US2001 z-drives. The z-drives will feature 2,300 mm diameter stainless steel propellers inside Kort Nozzles. Estimated bollard pull for the vessel will be 59 tons and the vessel will carry an ABS International Loadline.

Electrical service will be provided by a pair of 100 kW generators powered by John Deere engines.

Deck equipment includes a Markey DYSF-42 hydraulic bow winch, carrying 500 ft of 8 in circumference Plasma line, and a Washington Chain and Supply 100 ton quick-release tow hook.

Other features will include Engine Monitor Inc. USCG-approved engine and fire/smoke alarm systems, complete electronics package including Simrad GPS/Autopilot and Foruno Radar and AIS units, Heli-Sep USCG-approved Oil/Water Separator, Owens Kleen Tank sewerage treatment plant and 1000 gpm fire-fighting capability.

Tankage includes capacity for 43,000 gallons of diesel, 1,800 gallons of lube and hydraulic oil, 11,000 gallons of potable water and 1,500 gallons of dirty/waste oil.

Construction is scheduled to commence in January 2005 with an estimated construction time of twelve months.

Bisso Towboat says the tug, to be named Alma S., "will be an almost exact carbon copy of our Cecilia B. Slatte," a 4,300 HP reverse z-drive ship-assist tug also constructed by Main Iron Works in 1999 that was the first reverse z-drive ship-assist tug on the Mississippi River. The new tug will feature a few minor modifications, primarily in the areas of increased crew comfort and improved operational capabilities.

The new tug will join Bisso Towboat's fleet of 12 ship-assist tugs on the Lower Mississippi River, primarily servicing the large bulk carriers and tankers that call in the River
