The Brazilian Navy is to buy three Offshore Patrol Vessels from BAE SYSTEMS, UK, two for delivery in 2012 and the third in 2013. The contract includes supply of ancillary support services and a technology transfer agreement allowing licensed production of further vessels in Brazil. The LOA is 295 ft (90 m) and displacement is 1,800 tons. A conventional propulsion layout uses twin high speed MAN 16V28/33D diesels rated at 7,350 kW at 1,000 rpm driving Wärtsilä propellers. During sea trials, the ship achieved a speed of 25.4 kn, range is 5,500 miles and endurance 35 days. [More]

At the recent Ft Lauderdale Boat Show, Northern Lights Inc, manufacturers of generators and Lugger brand diesels announced a hybrid propulsion system. It combines their long standing expertise in marine generator design with BAE Systems’ HybriDrive technology, used with considerable success in commercial motor vehicles in several countries. Currently in service in over 3,500 applications worldwide, the HybriDrive system uses a Propulsion Control System (PCS) to direct power produced from the generator(s) for immediate use, or hold it in an Energy Storage System (ESS) - a special battery pack, to later provide emission free and silent power from the electric propulsion motor. The system is applicable to sailing yachts as well as motor yachts. The electric propulsion motor can also operate as a generator to charge the ESS by harnessing the energy of a “windmilling” propeller. [More]
