Wind Turbine Generator Foundations
WTG Foundations
Seaway 7 offers installation services for WTG foundations through its Heavy Lift Vessels (HLV), Seaway Strashnov, Seaway Yudin and its new custom built foundation installation vessel, Seaway Alfa Lift.
In the last 12 years Seaway 7 has built up an extensive track record in installing a wide range of foundation types, ranging from monopiles and suction bucket jackets to tripod and pre-piled jackets using a pile installation frame.
For installation, we are using an impact hammer and/or vibratory hammer depending environmental and soil conditions. To minimise the environmental impact, Seaway 7 will provide pile driving noise mitigation measures based on the latest available technology.
Following a multi-year innovation program, we have developed and successfully tested a method whereby monopiles can be installed on dynamic positioning. To date, installing monopile foundations on anchors rather than using dynamic positioning has been the norm. This specialised solution allows us not only to reduce our installation cycle times but the overall project duration and the associated cost. Any limitations with regards to impacting the seabed or local infrastructure have all but been removed.
Seaway Alfa Lift
In 2022, Seaway 7 will welcome heavy lift crane installation vessel, Seaway Alfa Lift, a custom-built vessel for installing offshore wind foundations. The vessel is designed specifically to install XXL monopiles and jacket foundations with maximum efficiency, designed around Seaway 7’s innovative approach to installation with a fully automated foundation handling system.
