It is understood that these LNG vessels will be used by major Asian shipping companies including China Shipping (Group) Corporation and Sinopec Kanton Holdings Co., Ltd., mainly for transporting LNG from Australia to China. Ship delivery period is from April 2016 to November 2017.
At present, the use of steam turbine or two-stroke engine technology is commonly used on LNG ships. Therefore, the dual-fuel engine electric propulsion system is used for the new LNG ship, which is a milestone for the development of China's large-scale ship propulsion system. Electric propulsion technology is more efficient, consumes less fuel, and reduces environmental impact. At the same time, the compact electric propulsion system also increases the cargo load of the ship. GE will equip each ship with two propulsion systems, including engine, main switchboard and cargo switchboard, MV7000 transformer, motor and remote controller. It is also responsible for the design, manufacture, commissioning and personnel training of related equipment and provides sea. Try to support.
GE's induction motors with pulse width modulation propulsion technology are powered by high-efficiency dual-fuel engines that use natural gas, marine diesel or heavy oil. At present, the dual-fuel engine uses the evaporative gas from the cargo tank on board, combined with GE's electronic variable speed drive equipment, is becoming a mature solution commonly used by LNG carriers.
Paul English, head of the ship's business at GE's Power Conversion Division, said that GE's design combines inductive technology with pulse-width-modulated converters to provide power stability with cost-effective stability. solution. GE will provide technical support to Hudong Zhonghua during the system design phase and leverage its expertise in the field of electric propulsion solutions.
The relevant person in charge of Hudong Zhonghua said: "This signing has opened a new chapter in our cooperation with GE Power Conversion Division. We look forward to establishing a mutually beneficial and high-level cooperation relationship with GE."
Paul Ingrich also pointed out: "The signing of the relevant contract with Hudong Zhonghua is a major initiative of GE Power Conversion Division to continuously support the development of China's shipbuilding industry."
