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.
In 2022, Seaway 7 will welcome heavy lift crane installation vessel, Alfa Lift, a custom-built vessel for the installing of 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.
