Japan Offshore Marine (JOM), a joint venture between DEME Group and Penta-Ocean Construction Co., Ltd., has secured a contract for the Oga-Katagami-Akita Offshore Wind Project in Japan.
JOM will be responsible for the engineering and offshore installation of 21 Vestas V236-15 MW wind turbines. The project will introduce this turbine class to Japan for the first time.
The offshore installation scope will be carried out by the jack-up transport and installation vessel Sea Challenger, which will operate under the Japanese flag when offshore works begin in 2027.
The contract combines DEME Group’s international offshore wind expertise with Penta-Ocean Construction Co., Ltd.’s local execution capabilities. Through JOM, the partners will support further offshore wind development in Japan and help build domestic capabilities.
