Penta-Ocean and DEME Offshore sign memorandum of understanding to collaborate on construction of offshore wind projects in Japan
Tokyo, Japan – Mar. 24, 2020 –Penta-Ocean Construction Co., Ltd., Japan’s leading marine contractor, and DEME Offshore, Belgium’s leading offshore marine engineering company, have concluded a memorandum of understanding (MOU) regarding comprehensive cooperation for the construction of offshore wind farms in Japan.
In light of recent regulations*1 which promote offshore wind power generation in the general sea areas, as well as in port and harbour areas, the development of offshore wind projects has gained considerable momentum throughout Japan.
However, offshore wind projects can face very complex subsoils due to mixed sandy and rocky, sometimes soft grounds, together with severe metocean conditions like typhoons, bomb cyclones, etc. In addition, seismic forces need to be considered.
By combining DEME Offshore’s extensive experience and technological know-how in Europe with those of Penta-Ocean in Japan, we will be able to provide comprehensive solutions to these challenges. We believe that our collaboration will make a significant contribution to the further expansion of Japan’s offshore wind industry, through the realisation of safe and highly efficient construction methods.
As a first step, we will start with the introduction and development of advanced technologies that are deemed useful and beneficial to the Japanese market, leading to joint execution of offshore wind farm projects in Japan.
