Next Geosolutions has signed an eight-year framework agreement with 50Hertz to deliver geotechnical seabed survey services for offshore substations in the North Sea and Baltic Sea.
The multi-million-euro deal will see NextGeo act as primary provider of survey support to the German transmission system operator, which is part of Elia Group.
Survey work will be carried out using the company’s offshore fleet, including the geotechnical drilling vessel NG Driller, supported by advanced technology to ensure safe and efficient delivery.
NextGeo said the agreement highlights its growing position as a reference partner in Europe’s offshore renewable markets, dedicated to advancing the energy transition.
Valentina De Rienzo, chief commercial officer of NextGeo, said: “This signing with 50Hertz is the result of a great commitment to building long-term relationships with our clients. It highlights the strength of our commercial strategy and confirms NextGeo’s role as a trusted partner in supporting the development of European offshore energy infrastructure.”
Frank Koopman, offshore wind strategy director at NextGeo, added: “We are proud to have gained the trust of 50Hertz in our specialised people and technologies to provide them with the data that will be fundamental for the safe and efficient design of their offshore substations in Germany.”
