Wind farm design

Pelagian's consultants have played an active role in the design of offshore wind farms, creating a detailed layout plan of the wind turbine positions, array cables and export cables.

Our consultants are highly experienced cable professionals, surveyors, geologists, engineers and oceanographers with a deep understanding of the marine environment and the related risks to offshore construction.

Pelagian uses the industry standard MakaiPlan GIS software for engineering the cable routes, computing cable quantities and managing the survey and installation of the wind farm export and array cables. The same process is used for subsea power interconnector and telecommunications cables.

Experienced personnel

Pelagian has contributed to high profile projects in the renewable energy sector during the last eight years. Our representatives have been an integral part in the design, survey, installation and ongoing maintenance of many of Europe's wind farm projects.

Pelagian provides multidisciplinary consultants to advise the customer on all aspects of marine operations, from cable manufacture and testing to marine survey and installation, through to system commissioning and ongoing operations and maintenance. Whether embedding seamlessly into a client's office or operating in the most challenging and austere of site locations as customer representatives, our team provide unparalleled expertise to keep the project on track and on budget.

Pelagian also specialise in crew and specialised staff for offshore operations. Offshore renewables (wind, wave & tide), telecommunications, power interconnectors or security cleared staff for military cables - we can provide site and vessel personnel for any cable project.
