Seattle-based naval architecture and marine engineer- ing ? rm, Jensen Maritime, has announced the delivery of the Hawaii, the ? rst of two 120 x 35 x 19 Jensen- designed ABS machinery class ocean-going tugboats, to Hyak Maritime, a marine equipment and vessel owner based in Dover, Delaware. The Hawaii was built by JT Marine of Vancouver, Wash. Hyaks second tug, the Wash- ington, is scheduled to be delivered by the end of 2013. The Hawaii and Washington are based on the successful Titan class tugboats, which Jensen developed alongside Western Towboat, a Seattle-based tug and barge company. Western Towboat is currently constructing its seventh, Jensen-designed, Titan class tugboat. 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 ser- vice, machinery classed Hawaii and Washington consume signi? cantly less fuel and enjoy much lower maintenance costs than other equivalently powered oceangoing tug- boats. Measuring 497 international tons and 91 regulatory tons, the tugs are quali? ed to sail in all U.S and world- wide waters with the smallest possible crew. They are ? t- ted with a pair of Schottel 1515 Z-drive units for superior maneuverability of tows in port and in close quarters. Liv- ing spaces are acoustically-dampened and ? reproofed us- ing the NORAC and Danacoustic systems, ensuring crew comfort and safety. Bollinger Shipyards have delivered the DP 2 classed Ocean Sky, the fourth of four Ocean Class tugs for Crow- ley Maritime Corporation. The ? rst two Ocean Class ves- sels, the Ocean Wave and Ocean Wind, classed as DP1 were delivered in Q4 2012. Ocean Sky sister vessel to the Ocean Sun was delivered back in May. At 156 feet in length, the Ocean Sky and Ocean Sun are 10 feet longer than the ? rst two vessels and are rated at 10,880 HP. The vessels are out? tted for long-range, high-capacity ocean towing, rig moves, platform and ? oating production, stor- age and of? oading (FPSO) unit tows, emergency response and ? re? ghting. All four vessels were built at Bollinger Marine Fabricators, LLC in Amelia, La.
