At the start of the year, Ocergy returned to MARIN for the third time to test the 15+MW design of its OCG-Wind™ Float—a floating wind platform designed with cost-efficiency and scalability in mind. Central to this evolution is an optimised assembly process using prefabricated steel sub-assemblies, aimed at reducing costs and accelerating deployment.

Ocergy is currently advancing two high-profile demonstrator projects that are turning heads in the floating wind industry:

In the Culzean Wind Project, which has been selected by TotalEnergies for the Culzean field in the North Sea, the OCG-Wind™ platform construction is completed and will support a 3 MW wind turbine. It will be connected to an offshore gas platform as part of the Scottish Crown Estate’s INTOG initiative, which focuses on decarbonising offshore oil and gas operations.
The RECORD15 (short for REduced COmmercial Risks with Demo of 15+ MW) Joint Industry Project is an ambitious initiative for which these model tests were performed. This project will culminate in the installation of a 15 MW+ turbine on an OCG-Wind™ floater by 2028.

A COMPLEX PROJECT PUSHING THE LIMITS

Over the past decade, offshore wind turbine sizes have shattered expectations, and floating wind technology is unlocking access to deeper waters with more consistent energy yields. The latest OCG-Wind™ design is engineered to meet the demands of these larger turbines, featuring tower frequency tuning that extends above the blade rotational frequency; the so-called stiff-stiff configuration.
