Fuji Electric Co., Ltd. (headquartered in Tokyo, Japan; led by President Michihiro Kitazawa) is pleased to announce the launch of a laser gas analyzer for EGCS to strengthen the ship systems business.
In the aim of reducing emissions of sulfur oxides (SOx), a substance responsible for air pollution, the International Maritime Organization (IMO) has set an upper limit of 0.5% on the sulfur content of ship fuel oil in all sea areas except designated sea areas*1 to be achieved by 2020 (current limit: 3.5%). This regulation will apply to all ships, existing and newly constructed ones. Once this regulation is strengthened, ship owners will have to switch to fuels with lower sulfur content or install exhaust gas purifiers (SOx scrubbers).*2 In addition, ships equipped with SOx scrubbers will be required to continuously monitor the ratio of sulfur dioxide (SO2) to carbon dioxide (CO2) gas content as an indicator of the exhaust gas purification performance.
Recently, Fuji Electric launched the world's smallest “laser gas analyzer for EGCS” as such an exhaust gas monitoring system. It also launched an Exhaust Gas Cleaning System (EGCS) for ships in 2018. The company will further strengthen its ship systems business by applying this product to its own EGCS and by expanding sales of this analyzer to other scrubber manufacturers.
*1 The seas of North America, the Caribbean, the North Sea, the Baltic Sea and others. Regulated at 0.1% from 2015.
*2 Equipment that mixes exhaust gas with seawater and reduces the sulfur oxides content of the gas.
3． Main Applications
Bulkers, tankers, container-ships, car carriers, etc.
