Segment TOPIC

Efforts towards realizing a sustainable marine business
In August of this year, Seika Daiya Engine Co., Ltd. (SDE), which develops marine engine business, and Maruha Nichiro Group agreed to cooperate on “reducing CO2 emissions at aquaculture farms” as part of the Maruha Nichiro Group’s efforts to address climate change. SDE leased an electric propulsion vessel (EV vessel) that it has developed to Maruha Nichiro AQUA Co., Ltd., a Maruha Nichiro Group company, and begun demonstration operations.
In addition to identifying issues related to the operation of EV vessels in aquaculture farms, SDE will install AI CAPTAIN®, an autonomous navigation system developed by Eight Knot Inc. (with whom SDE entered into a capital and business alliance last year) on the vessels in order to solve issues facing the marine business, such as safety and the shortage of crew members, that are expected to become even more serious in the future. SDE will continue its efforts to realize its vision of “decarbonization, manpower saving, and labor saving.”
