“Seawing” kite system to be installed on Corona Citrus, for Electric Power Development Co. Ltd

Press Release: Kawasaki Kisen Kaisha, Ltd. (“K” LINE) and Electric Power Development Co., Ltd. (J-POWER)  have decided to install the “Seawing”*, an automated kite system using wind power, on CORONA  CITRUS, an 88,000 DWT-type special coal carrier for J-POWER.


Completed on September 11th, 2019, CORONA CITRUS is equipped with a ballast water  treatment system for protecting marine ecosystems. The coal carrier also comes with a SOx  scrubber, which eliminates sulfur oxides in exhaust gas from its engine, so as to comply with the  regulations on SOx emissions that came into effect globally in January 2020. 


The newly installed “Seawing” is expected to reduce CO2 emissions from the ship by at least  20%. Thus, it is one of main “K” LINE’s initiatives to achieve its GHG reduction target.
