Covering all aspects of offshore engineering studies and concepts
From FEED to procurement, construction, installation and O&M
Experienced in-house engineering teams
From the onshore substation to and including the offshore substation and wind farm, our expertise covers every aspect involved in transmitting electricity from offshore turbines to the onshore grid. Thus, we can offer a full scope of engineering services, ranging from front-end engineering and design (FEED) to procurement, construction, installation, operation and maintenance.
With more than 30 years of experience working in the offshore energy sector, we understand the challenges involved in operating in a harsh offshore environment. Moreover, when you are a long way from shore, you need reliable solutions you can count on.
Based on the vast in-house knowledge and experience of our engineering teams and external partners we can offer as an example the following key topics as part of a FEED:
