GE’s power conversion division has won a series of orders from South Korea-based Daewoo Shipbuilding and Marine Engineering (DSME) and Hyundai Heavy Industries (HHI) to provide propulsion systems to 23 new LNG carriers.
The systems are to be delivered by GE’s facilities in France and represent a total power of 1,105 MW.
Under the deal, GE will provide MV7000 converters, induction motors, transformers, generators, main and cargo switchboards and propulsion control systems.
GE’s rotating machines facility in Nancy, France will be responsible for the production of all propulsion motors, while the engineering works will be carried out at the GE French merchant marine centre in Belfort.
GE said that its motors and converters were designed for easy maintenance, high efficiency, availability and layout flexibility.
According to GE, the induction motors will have a compact design and be powered by press-pack IGBT pulse wide modulation (PWM) converters to offer reliability.
The company said that the dual-fuel engines combined with electric propulsion would offer up to 30% improved efficiency compared with traditional LNG tanker propulsion using boil-off boilers and steam turbines, as well as increasing cargo capacity by 3%-5%.
In 2011, HHI secured a $400m order from BW Maritime to build two LNG carriers and a $600m order from Dynagas to build two 155,000m3 LNG carriers.
