Offshore wind farm cable technology

Sustainable Portfolio

The demand for (green) energy is growing in connection with the ongoing electrification, which means wind parks are getting larger and the demand for connectivity solutions is rising. As part of TKH’s strategic program Accelerate 2025 TKH has built a new (second) Subsea factory, in Eemshaven, the Netherlands. The new building is gas-free and 500 solar panels have been installed, which will later be expanded with even more solar panels.

With this production expansion, TKF focuses specifically on the production of inter-array Subsea cables, which connect the wind turbines and offshore wind farms with the substations. The innovative cable concept is easy to install compared to commonly used yarn-bitumen cables, and provides the customer with installation efficiency, cost savings, and a reduction in risks during cable installation. Our innovative cable specifications are composed of durable materials. A high carbon footprint reduction is achieved based on increased recyclability (in and out) and fossil free powered production. With the construction of this new factory, TKF is also getting ready for developments towards 132 kV and floating wind farms including new innovations such as optical strain monitoring. From the moment the factory is in operation, 1,200 kilometers of Subsea cable can be produced per year.

In 2023, TKH and Vattenfall established multi-year framework agreement for the supply of inter-array cables for offshore wind farms in Europe. This agreement covers the supply of 66 kV inter-array cables and will apply to all bottom-fixed European wind farms developed by Vattenfall in the coming years. The first projects to be called off will be for the German Nordlicht cluster. The contract is initially signed for three years and can be extended by five more years.
