Seaway 7, the Renewables business unit of Subsea 7, has been active in the offshore Renewables Energy industry since 2009, when we installed our first Wind Turbine Generator (WTG) monopile foundation offshore in the UK, and has since built an industry-leading track record in installing WTG foundations, substations and inner array cables for many of the key offshore wind developers in Europe, Taiwan and the US.
Today Seaway 7 has installed 645 WTG foundations (totaling 3GW capacity), 30 substations and 1500km of inner array cables. Fast forward to today and we have multiple projects under ongoing execution for an additional 375 WTG foundations (equaling 4 GW) and 1900km of inner array cables.
GW Installation Involved
Seaway 7 successfully completed the Beatrice Project (EPCI) in 2019. Beatrice, once fully operational, will be one of Scotland’s largest offshore wind farms, located approximately 13km from the Caithness coast. All Seaway 7 vessels contributed to deliver the design, fabrication and installation of 84 jacket foundations, weighing over 120,000Te, along with 165km of Inter-Array Cables.
In 2018 Seaway 7 was awarded the contract for the turnkey engineering, procurement, installation and commissioning (EPIC) works related to the inner array grid and export cable system of the Yunlin Offshore Wind Farm project. The offshore wind farm Yunlin is located approx. 8 km off the coast of Yunlin County within the Taiwan Strait on the west coast of Taiwan.
