Dutch TSO TenneT has recently awarded contracts related to its 2GW program. Energy and marine consultancy ABL has been awarded a contract to provide marine warranty survey services for the installation of three 2GW Export Cable systems whilst NextGeosolutions (NextGeo), specialist in marine geosciences and offshore construction support, won the contract for extensive geophysical and geotechnical survey activities, both offshore and nearshore.
ABL’s scope is for the IJmuiden Ver Beta, IJmuiden Ver Gamma and Nederwiek 2 grid connections. They are part of the 2GW program whereby TenneT will develop a total of seven 2GW offshore wind grid connections by 2030/2031. Combined, the 525 kV cables for the three projects are over 500 kilometres in length and will export 6 GW of electricity to the grid, enough to power up the equivalent of six million homes.
ABL’s scope of work includes the technical review and approval of all documentation, procedures and drawings related to the warranted activities, as well as suitability surveys. ABL’s German operation will also resource on-site attendances at both fabrication and loadout sites, as well as offshore, to review and approve warranted transportation and installation operations.
ABL’s Germany branch, based in Hamburg, will manage the project. The project will run until 2029. ABL has not disclosed the value of the contract.
Geophysical and geotechnical survey activities by Nextgeo Solutions
NextGeo’s contract, with a value of approximately €43 million, involves extensive geophysical and geotechnical survey activities, both offshore and nearshore, in the Dutch Exclusive Economic Zone.
Operational activities, scheduled to take place between the end of Q1 and Q4 2025, will include the execution of a “Marine Route Survey”, a critical investigation required for the proper design of the cable connections that will enable the Doordewind wind area to deliver renewable energy generated at sea to the onshore grid. Specifically, NextGeo will perform geophysical investigations and geotechnical sampling using advanced technical solutions, covering an area exceeding 21,000 hectares. Source: NextGeo and ABL
