SEP Vessel Responding to Installation and Construction of Wind Turbines

“Self-Elevating Platform” is also called “Wind Turbine Installation Vessels.” It is equipped with supporting legs which can rest on the seabed and move up and down. The vessel installs offshore wind power turbines safely by moving its own cranes and platform up to the sea surface with a crane. By raising and maintaining a level higher than the waves, the installation can be done even in rough sea. It can be used not only to install offshore wind turbines but also to support maintenance work on offshore oil and gas rigs. MOL holds shares in Cadeler, a leading Danish SEP ship owner that owns one of the world's largest SEP fleets. The SEPs owned by Cadeler are engaged in the construction and maintenance of offshore wind turbines around the world.

Power Cable Laying Vessel Business Responding to Growing Demand 

It is necessary to strengthen the nation's power system to transmit electricity from Hokkaido and the coast of the Sea of Japan, which are suitable for offshore wind power generation, to areas with great demand for electricity, so long-distance transmission methods using ocean routes are considered promising.
Cable Laying Ships adopt “Dynamic Positioning Systems“ to lay submarine cables with safety and precision, and MOL group have accumulated technology and expertise to automatically maintain the ship position under various environmental and weather conditions. We aim to utilize our know-how in power cable laying work for offshore wind power generation facilities.

The MOL Group has been responsible for ship management and the operation of four cable-laying ship in total, owned by KDDI Cable ship Co.,Ltd., (wholly owned by KDDI, hereinafter called KCS”) for over 50 years. In order to respond to the demand for power cable-laying ship that are expected to grow, MOL signed a memorandum of agreement for cooperati on in power cable installation with KCS in September 2021 and promotes the commercialization of the power cable-laying ship business. In addition, we will take on the role for the development of cable laying support vessels as the project selected by NEDO in June 2023.

Asia's first SOV business

Service Operation Vessel (SOV) has accommodations for wind farm service and maintenance technicians, allowing them to stay on-site for extended periods. SOVs are equipped with a dynamic positioning system (DPS) to constantly maintain a safe distance between the vessel and the offshore wind farm, as well as a special gangway with a motion compensation function (absorbing hull movement due to wind and wave action and so on), allowing safe and easy access between the vessel and the offshore wind turbines.

Ta San Shang Marine which is a JV established between MOL and Ta Tong Marine, our key business partner in Taiwan, started the operation of the first newbuild SOV in Asia "TSS PIONEER" in 2022.  TSS PIONEER has been engaged in O&M support for the Greater Changhua Offshore Wind Farm under a Time Charter contract with Ørsted, the world’s largest offshore wind developer.
Furthermore, in November 2023, Ta San Shang Marine signed a shipbuilding contract with the Dutch Shipbuilding Company, Damen Group for the 2nd SOV “TSS CRUISER”. This vessel is being built at a shipyard in Vietnam and is scheduled for completion by the end of 2025. After delivery, “TSS CRUISER” is planned to be engaged in support operations for offshore wind farms in Taiwan.

Ownership, Management, and Operation of CTV

Crew Transfer Vessel (CTV) is a transportation vessel that delivers wind farm technicians to offshore wind turbines with a relatively short distance from the port. (Passenger capacity 12-24 people) The fender attached to the bow is pushed on the offshore wind farm facility to transfer technicians from CTV in safe. Standard vessel type is aluminum catamaran.
In order to provide safe, secure CTV services, MOL has been engaged in the research and development of hull forms optimized for the inclement weather and nautical conditions of Japan. Performing verification tests in a water tank and simulations of wave motion characteristics when sailing and entering ports, MOL develops the best hull form for Japanese waters. 

From June 2023, MOL group put three crew transfer vessels into the offshore windfarm at Ishikari Bay New Port to support the construction and operation of the project. In addition, one of the CTVs, The KAZEHAYA owned by MOL, is the first CTV in Japan managed and operated under International Safety Management (ISM) Code, which is the international standard of the ship safety management system, certified by Nippon Kaiji Kyokai (Class NK) .

Enhancing the sophistication and quality of supply chain services
by participating in the power generation business

In order to anticipate the standards and needs of the offshore wind industry, we believe that our involvement in the power generation business itself, which is the core of this industry, will enable us to enhance the sophistication and quality of our supply chain services, which is one of the strengths of our Group. By combining and packing these supply chain services, we will provide comprehensive services and one-stop services that can only be offered by our Group. 
For example, fixed-bottom offshore wind farms are currently the mainstream, but floating offshore wind power projects are highly promising. We are the only company in Asia with experience of owning and operating FSRUs, and the floating offshore wind power businesses is an area where we can utilize our knowledge and expertise in offshore businesses and offshore structure operation. As the floating offshore wind turbines are installed at a longer distance from the coast, their supply chains are also expected to be longer and larger. We are positive that our strength can be utilized throughout the entire process, including towing, installation, mooring, maintenance, and operation of wind turbine components and foundations (floating structures).
