In light of recent regulations 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, the company will be able to provide comprehensive solutions to these challenges. DEME Group believes that its 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.
The first step is to introduce and develop advanced technologies that are deemed useful and beneficial to the Japanese market, leading to joint execution of offshore wind farm projects in Japan.
DEME Offshore is a subsidiary of the DEME Group, a world-wide solutions provider in the highly specialised fields of dredging, offshore energy, environmental and infra marine works. The company recently achieved a record with more than 2,200 offshore wind turbines successfully installed. Its expertise includes the transport and installation of foundations and turbines, specialised technology for XL drilled monopiles, the installation of subsea power cables, and the Operations & Maintenance activities necessary beyond commissioning.
The company owns a comprehensive fleet of installation vessels, including seven Self-elevating platform (SEP) vessels equipped with cranes that have lifting capacities up to 1,500t, the revolutionary floating heavy lift vessel ‘Orion’ with a 5,000t crane, and other specialised vessels for cable installation, wind farm maintenance and offshore services.
Penta-Ocean has an extensive track record and knowledge in marine civil engineering works in the maritime areas surrounding Japan. The company has a track record in the design, construction and removal of a demonstration offshore wind power facility in the Hibikinada District of Kitakyushu Port (Fukuoka Prefecture). It owns the first Japanese offshore installation vessel, ‘CP-8001’, which is equipped with an 800t crane, and is currently building a second new vessel with a 1,600t crane.
