Penta-Ocean Construction Co Ltd. and Belgian offshore marine engineering firm DEME Offshore plan to work together on the construction of offshore wind parks in Japan. The two companies have signed a memorandum of understanding (MoU) regarding their comprehensive cooperation in this field, they said on Tuesday. The announcement comes after Japan's recent introduction of regulations to promote offshore wind generation in the general sea areas, as well as in port and harbour areas. The first step of the new partnership will be to launch advanced technologies that are considered to be useful and beneficial to the local market.
