MITSUI E&S received orders for two units of “WT-3” high-pressure BOG compressor from Mitsubishi Shipbuilding. The WT-3 BOG compressors will be delivered as one of LNG fuel supply systems of dual fuel engines to be equipped on 210,000 DWT LNG-fueled bulk carriers to be built by Imabari Shipbuilding Group.
Since 1961, MITSUI E&S has manufactured 3,900 units (incl. a subsidiary company) of reciprocating compressors for various industries, including petroleum refining and petrochemicals that pressurize and deliver gas through its reciprocating motion of pistons. On the basis of accumulated experience as a reciprocating compressor manufacturer in various industries for decades, we have been developing high-pressure BOG compressors for marine-use in collaboration with KAJI TECHNOLOGY CORPORATION, a subsidiary of MITSUI E&S.
WT-3 BOG compressor has been developed as a dedicated product for high-pressure LNG dual fuel engines, which boosts the pressure of surplus BOG naturally generated from LNG fuel tanks of LNG-fueled vessels up to 31.5 MPaG and supply it to the engines as fuel. Surplus BOG generated from fuel tanks used to be burned and disposed, however it can be utilized effectively as fuel for LNG-fueled vessels with the compressor. WT-3 BOG compressor provides easy installation by its compact design and contributes to the reduction of fuel consumption, which leads to lower operating costs and CO2 emissions of LNG-fueled vessels.
MITSUI E&S has manufactured the largest number of two stroke LNG dual fuel (ME-GI) engines in Japan and for LNG fuel supply systems, we have already added high-pressure pumps, “MHP-3” to our own product portfolio. Now we can provide main equipment for LNG-fueled vessels by ourselves not only for dual fuel engines, ME-GI and high-pressure pumps, MHP-3 but also high-pressure BOG compressors, WT-3.
As a leading supplier of marine propulsion systems, MITSUI E&S will contribute continuously to de-carbonization of vessels for the realization of a sustainable society.
