Japan’s LNG carrier market enhances its gas fuelled merchant fleet with 61 engines from Wartsila.
A total of 16 new gas carrier ships powered by Wärtsilä dual-fuel engines are built in Japan. These engines are modelled in such a way that they are capable of running dually on liquefied natural gas (LNG) or conventional diesel fuels. Wärtsilä acclaims depth of experience and technological capabilities in gas fuelled propulsion solutions being a global leader in complete lifecycle power solutions for the marine and energy markets. This expert knowledge widened its market from the second half of 2014 and December 2015.
The current orders of wartsila include
- 20 nine-cylinder
- 25 six-cylinder
- 16 eight-cylinder Wärtsilä 50DF dual-fuel engines
This total of 61 engines that will be running primarily on LNG. These will be the first Wärtsilä 50DF engines delivered for Japan’s LNG carrier, of which 16 vessels have a gas cargo capacity of between 155,000 and 180,000 cubic metres, that will be used to deliver shale gas from the USA to Japan.
Highlights of 50DF dual-fuel engine:
- It has superior propulsion efficiency.
- The engine proves clear environmental advantages.
- The emission of nitrogen oxide (NOx) measures 85% IMO specification.
- CO2 is emitted 25% less than those of a conventional marine engine running on diesel fuel.
- The sulphur oxide (SOx) and particle emissions are negligible at almost zero percent.
- Both the gas admission and pilot fuel injection are electronically controlled.
- The engine functions are controlled by an advanced automation system that allows optimal running conditions to be set, independent of the ambient conditions or fuel type.
