AiP for floating offshore wind foundation

Odfjell Oceanwind has been granted Approval in Principle (AiP) by DNV for its Deepsea SemiTM floating wind foundation design. The design, suitable for turbines generating up to 15 MW, has been developed for low cost mass production and is intended both for floating wind farms and off-grid applications including temporary electrification of oil and gas installations in harsh environments, the classification society explained.

The design is suitable for water depths from 60m to 1,300m and is optimised for Siemens Gamesa’s SG 11.0-200DD and SG 14.0-222DD turbines. The class approval process has therefore involved both Odfjell Oceanwind and Siemens Gamesa.

Per Lund, Odfjell Oceanwind CEO, commented: “The AiP marks an important milestone for us. Building on the long-term relationship with DNV, we have chosen to work closely with them from day one in our development and will continue to do so for the class approval and certification of our fleet of mobile offshore wind units. The mindset from shipping that we share with DNV has proven very valuable for us in creating a product and service for floating wind power that scales much faster than what we have seen in the industry before.”

The Deepsea Semi design will be used for mobile offshore wind units (MOWUs) due to be ordered by Odfjell Oceanwind later this year. The MOWUs, operated as one fleet by the company, are scheduled to start operating in 2024.
