Heerema to Build New Float-Over Barge for TenneT’s 2GW Program Offshore Platforms

Heerema Marine Contractors is pleased to announce the signing of a contract with TenneT for the delivery of a new float-over barge, tailored to install the more than 30,000 mT 2GW Offshore Substations (OSS) crucial for the expansion of the Dutch and German electricity grids.

At Heerema, we are proud to play a key role in accelerating the energy transition. Our new float-over barge will be a vital asset in the installation of ultra heavy topsides, such as TenneT’s 2GW topsides, supporting the expansion of renewable energy capacity and reinforcing our commitment to innovation and sustainability in the maritime and energy sectors.

Arno Schroor, Project Director at Heerema: “To ensure the best installation methods for our clients, Heerema is committed to ingenuity. This project perfectly aligns with our commitment to innovation and supports TenneT's efforts to expand the North Sea electricity grid for renewable energy. It represents a significant advancement in sustainable energy, and we are proud to add this exceptional asset to our portfolio.”

This significant project is part of TenneT's ambitious investment strategy aimed at enhancing the energy infrastructure in the North Sea. Dick Lagerweij, Dick Lagerweij, responsible for the 2GW Transport and Installation contracts at TenneT: “The Dutch and German governments, on the basis of European climate goals and the desire to become more independent from fossil fuel, have tasked TenneT to expand the national power grids in support of offshore wind energy. TenneT’s 2GW program is based on standardisation and long-term agreements which allow contractors to invest in time to support and de-risks the program. Vital part of the 2GW grid connections are the DC (Direct Current) offshore power Converters, of which TenneT is planning to install more than 14 in the North Sea. We welcome the investments of Heerema in barges in support of Transport and Installation of these DC Converters.”
