Broad and comprehensive offshore design experience

Ramboll’s vast track record within offshore platform design is founded on four decades of offshore oil and gas experience and more than a decade designing offshore wind turbine foundations. Based on this solid background, our specialised engineers work internationally with the development and complete design of offshore substations.

Over recent years, we have carried out the detailed design of the offshore substation topsides and substructure for several of Northern Europe's largest offshore wind farms. 

Multidisciplinary design team

Ramboll’s multidisciplinary engineering team handles the entire design process from conceptualisation to detailed design – installation and commissioning.

We design substructures/jackets and develop topsides layouts with consideration to safety, mechanical handling, commissioning, operation and maintenance. The design includes implementation of electrical equipment such as transformers, reactors, GIS switchgear, MV/LV-switchgear, UPS system and SCADA/control systems and specification of all auxiliary equipment such as cranes, emergency diesel systems, workshops, fire-fighting systems and drain systems.
