Seaway Ventus installs its first WTGs

Last week marked a significant milestone for Seaway7 as the new build installation vessel Seaway Ventus successfully installed its first Wind Turbine Generators (WTGs).

The first turbine was completed on Tuesday afternoon on Ørsted’s Gode Wind 3 project, in cooperation with the WTG manufacturer Siemens Gamesa who provides installation crew and equipment onboard.

Situated 32 kilometres from the coast in the German North Sea, the turbine stands tall in 30 meters water depth, with the hub height measuring 126 meters and the rotor blades spanning 97 meters each.

Camilla V.P. Klejs, turbine installation delivery manager for Seaway7 said: “The delivery of the fully mobilised vessel to our client, and the installation of the first wind turbines is the result of more than three and a half years of careful consideration and design optimisations from a very dedicated team in the newbuild phase, as well as more than two years of planning from our project team”.

For Seaway7, renowned for its expertise in foundations and cable laying, this latest development heralds an exciting chapter as they expand their capabilities to encompass wind turbine installation. 

The jack-up installation vessel recently arrived in North Europe and is amongst the most capable jack-ups in the current market. It is capable of lifting components up to 207 meters above sea level and can operate in water depths up to 65 meters. For this project, the vessel is carrying components for four complete 11MW WTGs on each trip. 

The Seaway Ventus will continue installing turbines on the Gode Wind 3 project before transitioning to Borkum Riffgrund 3, which Orsted is building concurrently. Contracted for a fixed period, Seaway Ventus is working alongside Cadeler’s newly upgraded vessel Wind Osprey to install the 106 Siemens Gamesa’s SG 11.0-200 DD wind turbines.

Maria Eidesvik, VP Europe and US for Seaway7 said:“As we celebrate this milestone, Seaway7 reaffirms its position as a leading tier one contractor in offshore wind – now offering the complete value chain in the construction of offshore wind farms. This achievement underscores the collective expertise of our dedicated colleagues in Seaway7 and the good collaboration we have with our client Ørsted and with the turbine manufacturer Siemens Gamesa. We look forward to continuing this strong partnership to ensure the safe and efficient completion of the projects.”
