(FREELAND, Wash.) — The third of four ASD-90 tugs for Foss Maritime, Leisa Florence, was launched at Nichols Brothers Boat Builders (NBBB) on Nov. 18.

The ASD-90 tugs are designed by Jensen Maritime Consultants of Seattle. The 100-by-40-foot z-drive tractor tugs are built to U.S. Coast Guard Subchapter M regulatory standards, with ABS load line certification and UWILD notation.

Leisa Florence is equipped with two MTU series 4000 main engines, meeting Tier 4 emission standards, coupled to Kongsberg US255 azimuth thrusters. The propulsion package will produce over 90 tons of bollard pull. The vessel is outfitted with Mackay Marine electronics and Markey winches forward for ship assist and aft for barge towing.

Foss welcomed Jamie Ann and Sarah Avrick into its fleet in April and September, respectively. Leisa Florence will join the fleet in December after final outfitting and trials are completed at NBBB.

“The launch of every vessel is a special moment in its construction, bringing the boat into it’s natural environment,” said NBBB CEO Gavin Higgins. “We are very proud of the opportunity Foss has given us with this series of tugs. The team have worked very hard to complete all three vessels in these difficult and challenging times, with the fourth vessel coming shortly.”

“We are excited to see Leisa Florence launched in these difficult times,” said Will Roberts, chief operating officer at Foss Maritime. “We look forward to seeing Leisa at work for our customers.”
