Cooperation between Guangzhou Diesel Engine Factory Co. Ltd (GDEF), located in South China and the Norwegian maritime research institute Marintek based in Trondheim has led to the development of a new LNG ship engine. The Guangzhou Diesel/Marintek LNG motor is now ready to be certified by DNV, and will be available in the Chinese market this year. It is reported by Norway’s government website on China that while maritime transport is an energy effective mode of transport it still accounts for considerable CO2 emissions, estimated at half of that of all the cars in the world. LNG eliminates sulphur emissions, significantly reduces NOX emissions and cuts CO2 emissions by at least 20 % over comparable diesel engines.

Based on a test model of a LNG (liquefied natural gas) ship engine created in Marintek’s research institute, the GDEF/Marintek engine is expected to become popular in China for several reasons:

  • The Norwegian-Chinese 6230SG LNG engine will perform as well as a diesel motor.
  • The 6230SG LNG engine meets the new IMO emission standards that will come into effect already in 2016. These entail, among other things, that NOx emissions cannot be larger than 2 gram per kw/h.
  • Even though a LNG fueled engine is more expensive than a conventional engine, LNG is less expensive than diesel, making LNG engines an investment which pays back over time.

“As a significant shipping nation with a clear position on climate change, Norway has made reduction of CO2 emissions from maritime transport a priority. The co-operation between Marintek and Guangzhou Diesel makes for a concrete contribution to this aim. It also illustrates the potential in Sino-Norwegian co-operation in the maritime sector”, says Consul General Tormod C. Endresen.
