Global offshore wind leader Ørsted announces the signing of a 15-year contract with Ta San Shang Marine Co. Ltd., a joint venture of Taiwan's Ta Tong Marine Group (TTM) and Japan's Mitsui O.S.K. Lines (MOL), chartering the shipping company to build the world's first-ever Taiwan-flagged service operation vessel (SOV) for the operation and maintenance (O&M) of Ørsted's Greater Changhua offshore wind farms, the company said in its release.
Mock-up of the Service Operations Vessel to be deployed on Ørsted’s Greater Changhua offshore wind farms. The detailed design of the vessel is yet to be finalized.
This charter contract represents the first-ever bespoke SOV in Taiwan and in Asia Pacific. It signifies that Ørsted continues to invest significantly in the Taiwan market, both financially and by transferring its world-leading O&M expertise.
Scheduled for delivery in early 2022, the SOV will use the Port of Taichung as its base port, where Ørsted's future O&M facilities will be located, due to its proximity to the sites, water depths for accommodating deep draft vessels, and navigational access. The SOV will be utilized to provide top-quality O&M services for the Greater Changhua offshore wind farms, which will be located 35 to 60 kilometers off the Changhua coastline.
Andreas Munk-Janson, Head of Operations of Ørsted Asia-Pacific, notes that this new SOV will ensure ultimate workability and efficiency of the daily O&M performance offshore, and, thus, the reliability and availability of the wind turbines. It also seeks to provide a very high standard of comfort and safety for offshore technicians and vessel crew.
The SOV is the first to be built to fit the complicated and harsh environment in the Taiwan Strait. It will house up to 60 technicians plus the crew and will only need to return to shore once a month. The smaller crew transfer vessels (CTVs), also used to facilitate O&M activities, can only carry a maximum of 24 people and have to return to shore on a daily basis.
Safety is a guiding principle for Ørsted, and so the newly built SOV will be equipped with advanced technologies, such as a motion-compensated gangway to enable technicians to 'walk to work'. This will not only save time for technicians when travelling with and climbing onto the wind turbines from the CTV, it will also significantly improve their safety.
The SOV will also use a dynamic positioning system to automatically maintain its position and a 3D motion-compensated crane to mitigate wind induced motions on the loads to further ensure that technicians can carry out maintenance in a safe environment.
Equally important is the well-being of the O&M technicians. As their 'home away from home', the SOV will feature comfortable cabins, a recreational lounge area, fitness facilities, and a variety of healthy catering.
In addition, the vessel will have a design of environmentally improved capabilities. It will be prepared for fossil fuel-free operation and have an optimized hull design and a battery-hybrid setup to help reduce fuel consumption and decrease carbon footprint.
These high specifications, which are drawn from Ørsted's state-of-the-art SOV fleet deployed in Europe, well demonstrate the company's extensive and unparalleled expertise across the entire offshore wind industry value chain.
About Ørsted in Taiwan
The Greater Changhua 1 & 2a offshore wind farms will be located 35-60 kilometers off the coast of Changhua County and have a capacity of approx. 900MW, enough to supply around 1 million Taiwanese households with green power. The construction of the offshore wind farms will be finalized between 2021 and 2022.
In June 2018, Ørsted was awarded the right to build another 920MW offshore wind in Taiwan through its Greater Changhua 2b & 4 sites. Changhua 2b & 4 are to be built in 2025, subject to Ørsted taking final investment decision on the projects in 2023.
Ørsted is also the co-owner of Taiwan's first commercial-scale offshore wind project, Formosa 1, which was extended from a capacity of 8MW to 128MW in 2019.
As the world leader in offshore wind, Ørsted operates more than 1,450 offshore wind turbines. Ørsted has installed approx. 6.8GW offshore wind capacity and has a further 3GW under construction, including Changhua 1 & 2a. In addition, Ørsted has secured the rights to build approx. 2.9GW offshore wind in the US by 2024, approx. 1.1GW in Germany by 2025, and approx. 0.9GW in Taiwan by 2025. It is Ørsted's ambition to have installed a total of 15GW offshore wind capacity world-wide by 2025.
