Seattle-based naval architecture and marine engineering firm Jensen Maritime today announced the delivery of the Hawaii, the first of two 120’x35’x19’ Jensen-designed ABS machinery class ocean-going tugboats, to Hyak Maritime, a marine equipment and vessel owner based in Dover, Del. The Hawaii was built by JT Marine of Vancouver, Wash. Hyak’s second tug, the Washington, is scheduled to be delivered by the end of 2013.
The Hawaii and Washington are based on the Titan class tugboats, which Jensen developed alongside Western Towboat, a Seattle-based tug and barge company. Powered by twin GE 8L250 EPA Tier II engines, each rated at 2679 HP/1999 KW at 900 RPM, the ABS Maltese Cross A1, towing service, machinery-classed Hawaii and Washington measure 497 international tons and 91 regulatory tons. The tugs are qualified to sail in all U.S and worldwide waters with the smallest possible crew. They are fitted with a pair of Schottel 1515 Z-drive units for superior maneuverability of tows in port and in close quarters. Living spaces are acoustically-dampened and fireproofed using the NORAC and Danacoustic systems.
