Danish offshore wind farm developer Ørsted has signed a 15-year contract with Ta San Shang Marine, 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.

Ta San Shang Marine is a joint venture of Taiwan's Ta Tong Marine Group (TTM) and Japan's Mitsui O.S.K. Lines (MOL),

"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," the wind farm developer said.

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.

Christy Wang, Taiwan General Manager, Ørsted Asia Pacific, says: "Ørsted develops, constructs and operates offshore wind farms around the world and is pioneering and driving offshore wind development in Taiwan. Not only are we building the O&M base in the Port of Taichung, we're also setting an unprecedented industry practice in Taiwan and the region by deploying the bespoke service operation vessel for the Greater Changhua offshore wind farms. More importantly, this SOV contract has given the Taiwanese vessel supplier a unique opportunity to tap into state-of-the-art technology in the offshore wind industry."

According to Ørsted, 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.

Also, the SOV will be equipped with a motion-compensated gangway to enable technicians to 'walk to work'. 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," the Danish firm said.

"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," Ørsted added.
