Seaway 7 offers a substantial range of technical services as well as contract models depending on client and project needs, principally focused around two products: (one) WTG foundations and (two) offshore cables.

Our services

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.
