Sea and Land Project Engineering Engineering Design and Consultancy Services for Renewable Energy Industries

Sea and Land Project Engineering is a London-based Design House providing structural design and consultancy services to the offshore renewables industry. Our experience in the design of Offshore structures spans back over 27 years to the oil and gas industry, where valuable experience was gained delivering a range of topsides and foundation structures.

Our renewables division was established in 2010 with our first design project – the design of Thanet substation and wind turbine generator (WTG) foundations. We have since designed a number of offshore windfarm substations and WTG foundations for the renewables industry, including several in European waters. The company also has considerable experience in European Codes and regulatory framework requirements.

Our team of experienced engineers and designers deliver lightweight and innovative designs using the latest software and design techniques. Experience in fabrication, transportation and installation ensures we deliver designs that are fabrication and T&I friendly and right first time.

We are an agile organisation that responds quickly to our clients’ needs so that we can provide thorough and expeditious support throughout the project lifecycle.

Sea and Land Project Engineering has designed offshore renewables structures with a total constructed capacity of 2,839MW.
