A diesel electric propulsion system from a fairly new company based in Bergen, Norwegian Electric Systems (NES), is to be installed in the self-elevating work and accommodation barge ‘GMS Enterprise’ now under construction in the Middle East by Gulf Marine Services (GMS). The propulsion system for the DP2 rig is NES’s proprietary Quadro Drive® VFD, which gives an exceptional level of safety redundancy with its Black Out Safety System (dubbed B.O.S.S.).Quadro Drive® The Quadro Drive®, explains the manufacturers, is specially designed for ship installation and meant to set the standard of next generation propulsion converters; there is no need for a large transformer, as there is just one unit to install, making installation much easier and less expensive. Quadro Drive® typology: Rendering courtesy of NES A modular-based system is the cornerstone of the Quadro Drive® which gives possibilities for interchangeable parts, and an option of derating the d...

The ARC 100 HD increases ice management and pollution control capability As a result of the increased tanker traffic in the Gulf of Finland and an innovation campaign Aker Arctic has developed a revolutionary new type of vessel, an asymmetric ice-breaker. This oblique icebreaker takes further the already well known "double acting" stern working icebreaking method by being able to break an ice channel of 50 m width by proceeding with the side ahead. In addition to icebreaking, the vessel is excellent also during the ice season in oil spill combat operations, in escort and emergency towing, fire fighting and ecological monitoring. Thus the vessel by its performance replaces several traditional vessels in a compact, cost-efficient high performance unit.The vessel is a compact size icebreaking vessel provided with diesel-electric propulsion with three azimuthing thruster propellers. The propulsion solution and the special hull form allow the vessel to operate efficiently ahead, astern and ... [More]

Disney Dream, Disney Cruises latest Caribbean cruise ship of 128,000 GT and 4,000 passenger capacity was delivered by German builders Meyer Werft on 15, December 2010 and is scheduled to make the transatlantic crossing for a maiden cruise departure on 26, January 2011 from home base Port Canaveral, Florida.  A Disney publicity department staffer described the cruise liner as offering guests, "A perfect blend of elegant Art Deco style and fun-filled Disney whimsy to create one of the most spectacular ships afloat." Yet apart from the hype, which is forgivable considering competition in the growing cruise marketplace, there has been little mention of the state-of-the-art construction of this huge liner, the biggest ever built in Germany, and of its hi-tech propulsion.Laser and 'Lego' Shipbuilding Disney Dream first began taking shape early 2009 using 'Lego' building principles in a totally enclosed weather-proof building hall enclosing the dry dock at Meyer Werft's shipyard at Pap...
