Single-lift Solution Selected for TenneT’s Ambitious 2GW Offshore Wind Project
Allseas’ superior single-lift technology has been selected to install supersized offshore wind converter stations for TenneT’s ambitious 2GW Program and play a key role in Europe’s energy transition.
Topsides and jackets for wind projects in the North Sea
The companies signed a multi-year framework agreement for the transportation and installation (T&I) of topsides and jackets for at least 8 Dutch and 6 German 2 gigawatt (GW) offshore wind projects in the North Sea.
Continuation of collaboration between TenneT and Allseas
Allseas has been awarded 15 “slots” for T&I of a supporting jacket or high voltage direct current (HVDC) converter topsides for the transmission of wind-generated power to shore. Allseas will deploy its revolutionary single-lift vessel Pioneering Spirit for the works.
The agreement continues the strong collaboration between TenneT and Allseas, following earlier offshore wind installation awards for transformer stations (700 MW) in the Dutch North Sea.
Safe installation and high workability
Pieter Heerema, Allseas’ President, said: “Pioneering Spirit’s unique transport and installation capability has been used to great effect to deliver critical assets for offshore energy and wind developments across Europe. Pioneering Spirit’s large lift capacity and high workability ensure that the installations can be safely performed all year round, creating maximum flexibility in the vast and complex building schedules.”
Advancing plans for offshore grid systems
Nine European countries including the Netherlands have pledged to boost their combined North Sea offshore wind capacity by at least 120 GW by 2030. To meet these ambitious goals, operators are advancing plans for next generation offshore grid systems supported by 2 GW converter stations.
Industry leading capabilities
“The next generation converter stations are substantial structures, similar in size to a football pitch and weighing up to 30,000 tonnes, housing complex and delicate HVDC technology that makes them a good match for our industry-leading installation capabilities,” said Pieter Heerema.
