 One of the first ships in the world to use a DC bus system for the main electrical installation recently entered service – the Abis Dover a 6000 dwt twin screw, diesel-electric powered, multipurpose special cargo vessel. M/V Abis Dover: Photo credit Alewijnse Marine Systems Built in the Shipkits shipyard in a project that included Vuyk Engineering Groningen, Alewijnse Marine Systems, all based in The Netherlands, and Finland’s Vacon, the ship’s upper cargo hold is a remarkable 80 m (262.5 ft) in length, almost 75% of the LOA of 107m (351ft), achieved by avoiding space-consuming propellor shafts and going for the diesel-electric propulsion option. Propulsion power comes from six Scania gensets, tucked away in space otherwise wasted, to drive steerable Z-drive thrusters. Not content with that, the design team set themselves the task of  overcoming the main disadvantage of conventional AC power, namely that all the generators have to run synchronously ... [More]
