Since more than 2 decades we advise our clients on major subsea power cable projects, contributing to the greenification of the world's energy supplies. We offer a unique combination of academic knowledge and a long history of field experience to provide smart solutions.

As trustful advisors we provide confidence from boardroom to backdeck level in new or existing subsea infrastructure projects, ensuring your interests are protected by balancing cost, risks and technology over the lifetime of the assets.

We are passionately guiding our clients on technical, contractual & commercial matters related to interconnectors, export systems, offshore wind farms, new technologies like hydrogen, CO2 pipelines, floating wind, offshore solar and other smart developments beyond the horizon.

We propose a comprehensive offering. This enables us to carry out complex projects holistically. But, of course, we would like to help you in any respect, also with the smallest task!
