The ABS-classed tugs will feature two MTU Detroit Diesel 16 cylinder series 4000 Marine Engines with M70 Rating, Lufkin Model MV1600S, with 2:1 ratio reduction gears, Rolls Royce model US 255 FP Z-drives, for a minimum thrust ahead of 80 tons at bollard condition.

The aft deck will be outfitted with an H-bitt fabricated from 16-in. Schedule 120 steel pipe. These tugs will be constructed in Washburn & Doughty’s new shipyard, which is scheduled for completion in June 2009. The new building measures 225’ x 155’ and features two construction bays, each equipped with two, twenty-ton cranes.
