Mitsui Engineering and Shipbuilding is scheduled to make equipment that reduces nitrogen oxide in the exhaust fume of ships by 76% practicable in 2016. The equipment is combined with the engine and installable inside the machine room. It will be installed in the bulk freighter introduced by NYK Line in 2015 and undergo demonstration experiment for several thousand hours to examine durability. It successfully reduced nitrogen oxide about 25% in the experiment conducted on land. NGK Insulators developed a technology to eliminate soot completely by applying the technology it developed for vehicles. The purification equipment developed by the company is based on the ceramic technology it has accumulated. All soot in the exhaust fume of a marine diesel engine is completely eliminated by the ceramic filter when it goes through the equipment.
Regulation on exhaust fume of ships is behind that of vehicles, but it will grow stringent worldwide beginning in 2016 because International Maritime Organization asked ships to be built after 2016 to reduce nitrogen oxide emissions by 80% from the level of 2010. In the future, regulation on soot is expected to be introduced.
