Seaway7 provides fully integrated Transport and Installation (T&I) services for offshore wind turbine generators (WTGs) utilising the company’s next generation jack-up installation vessel Seaway Ventus.
As a leading contractor in the offshore wind sector Seaway7, through its combination with OHT ASA, has made significant investments in next generation installation vessels and is committed to continuing the development of the fleet.
With a dedicated operational and commercial base for WTG installation in Vejle, Denmark, Seaway7 employs some of the offshore wind industry’s most respected and capable people. Between them they have worked on over 65 offshore wind projects across the globe. Our industry knowledge and highly competent team bring the very best in project management, project engineering and operational expertise, sitting alongside our well established and highly valued marine engineers and logistical experts.
With the organisation, people, vessels and systems in place, and a strong track record – Seaway7 are the ideal partner for the installation of offshore windfarms.
Responding to market and client demand for capable vessel capacity in the offshore wind market, Seaway7 has contracted China Merchants Heavy Industry (CMHI) to construct a self-propelled jack-up installation vessel with options for 3 further vessels. The GustoMSC NG-14000XL-G design vessel, due to arrive in 2023, is designed specifically to transport and install the next generation of wind turbines.
Seaway Ventus will be amongst the largest self-propelled jack-up installation vessels in the world. Designed specifically to transport and install the next generations of offshore wind turbines, to the highest environmental standards. The vessels will be capable of installing wind turbine components in water depths of >65m, to a height of up to 182m above the sea and will feature a telescopic leg-encircling crane with a maximum lifting capacity of 2,500t in retracted mode and 1,600t in extended mode.
The vessel will be equipped with well-balanced DP2 capability and VSD driven jacking systems, providing a controlled ramp-up / ramp-down, speed & torque control, for frequent, fast, and secure jacking operations. Special emphasis has been placed on providing a class leading environmental footprint by way of energy and heat recovery, battery hybrid solutions as well as a sophisticated electrical and control system, reducing CO2 emissions by 20% compared to similar units. The vessels have been future proofed for fuel cells powered by hydrogen to be installed to cut emissions even further when such technology becomes available.
