Master Boat building pair of rater tugs, first in US, for Seabulk

摘要

A pair of rotor tugs for Seabulk Towing, Trident and Triton, sue being constructed at Master Boat Builders in Bayou La Batre, Ala. Both 98-by-43-foot boats are scheduled for delivery in early 2017. They are the first Robert Allan-designed Advanced Rotortugs (ARTs) to be built and operated in the U.S. Damen has built two in Europe and three are being built at ASL Shipyard in Singapore. A rotor has three z-drive propulsion units configured in a triangle, as opposed to two stern-mounted z-drive units on an ASD tug.
