Kvichak Marine Industries recently delivered the second 44.5? Response Boat Medium ? C (RB-M C) to the New York City Police Harbor Unit. The  rst hull, P.O. Edward Byrne, has been in service since April 2010 providing maritime security and law enforcement along with search and rescue in the New York metropolitan area. A third vessel is currently under construction at Kvichak with delivery scheduled for late October 2012. These all- aluminum vessels are designed by Camarc Design, UK and powered by tier II compliant twin Detroit Diesel 60 series engines rated for 825 BHP each coupled to Twin Disc MG5114SC marine gears. Rolls Royce Kamewa FF375S waterjets are the chosen propulsion. The new vessels will be named at a special dedication ceremony to be held in New York. Additional vessel features include: Signal International, Inc., has landed a $94 million contract from Great Lakes Dredge & Dock Corporation, (GLDD) to build an Articulated Tug & Barge (?ATB?) Trailing Suction Hopper Dredge. The 15,000-cubic-yard- capacity Dual Trailing Arm Suction Hopper Dredge with a 14,000-horsepower tug is believed to be the  rst fully integrated ATB Dredge and the largest hopper dredge in the United States. The dredge barge dimensions are 410 ft x 92 ft x 36 ft (124.97m x 15.85 x 10.97m) with the tug measuring 150 ft x 52 ft x 36 ft (45.72m x 15.85 x 10.97m). The dredge will feature two 36-inch suction pipes and dredge at depths of up to 125 feet. The barge will have two electrically driven 800 horsepower tunnel thrusters. The tug will be classed ABS with A1, AMS, ACC, towing vessel unlimited notations. This ATB unit will be built to the USCG speci cation for Dual Mode ITB under NVIC 2-81. Both the tug and barge will be out tted with an Articouple FRC 90 connection system. The ATB will be equipped with a direct high power pump-ashore system, a hybrid power sharing con guration between the tug and barge, dynamic positioning and tracking, EPA Tier III compliant engines, and additional proprietary features designed to minimize the impact of its dredging process on the environment. GLDD partnered with Ocean Tug and Barge Engineering Corp. for the design and engineering of the tug and with Bay Engineering of Sturgeon Bay, Wisconsin for the dredge.
