Technology:
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.
Mitsui Engineeering and Shipbuilding is
very active in robotics, too
NGK Insulators means ceramics
