SCALEWIND

The Deepsea Star™ is a column-stabilized semisubmersible steel foundation for floating offshore wind.

It is designed based on the Odfjell Groups learnings from operating similar technologies in offshore drilling, with particular emphasis on lifecycle structural integrity, operational- and cost-efficiency in mind. The Deepsea Star™ technology is developed for 15MW+ WTGs in both harsh and benign environments in accordance with DNVs standards for floating offshore wind units.
Odfjell Oceanwind is a Norwegian floating offshore wind specialist that combines Odfjell’s 50 years of maritime legacy and experience in designing, building and operating floating units in harsh environments with 20 years of experience in developing floating offshore wind solutions. OOW provides floating wind designs, EPCI management services, and develops own wind park projects based on its technologies. In Norway, OOW is part of the GoliatVIND and UtsiraVIND projects. The company has offices in Bergen, Stavanger and Oslo. The largest shareholders in addition to Odfjell are the two Japanese companies Mitsui M.O.L. Lines and Kansai Electric Power.

Odfjell Oceanwind (OOW) has secured a slot with 24MW capacity grid connection at the Marine Energy Test Centre (METCentre), with the ambition of installing one full-scale floating offshore wind turbine in 2028. The project, named SCALEWIND, will demonstrate all components involved in a utility scale wind park including an extra large WTG, the Deepsea Star™ semisubmersible steel foundation, a mooring system, dynamic cables, as well as a subsea infrastructure for collecting and delivering the power to the onshore grid. OOW will also work closely with MetCentre in order to mature and develop the engineering, procurement, installation and commissioning of the seabed infrastructure which will be shared between the SCALEWIND project and potential other future demonstrators at the METCentre.
“Demonstrators like the SCALEWIND project are essential to de-risk floating offshore wind prior to scaling to larger projects like Utsira Nord, INTOG, Scotwind and others. The world has still not seen the technology that is required for developing these multi-turbine and multibillion-dollar projects. The largest floating offshore turbine deployed so far is 9.5MW, whilst the Utsira Nord and other utility scale projects are expected to use turbines with more than twice that capacity”, says CEO Per Lund in Odfjell Oceanwind.
“By deploying a single unit with relevant technology early we will demonstrate to key stakeholders like developers, investors, banks, insurance companies, certification agencies and authorities that the technology is timely reliable and available before much wider commitments are needed for the larger projects to come. This project will also offer valuable learnings for the supply chain and demonstrate many aspects of industrialization, before scaling to larger commercial projects. This reduces risk, time and cost for everyone involved, and will represent a much-needed step towards making floating offshore wind relevant in the energy mix.”
The SCALEWIND project will be organized as an alliance and aim to work with forward leaning industry players with a strategic interest in enabling utility scale floating offshore wind. Relevant industry players will be invited to participate in the project, and interested parties are also encouraged to reach out to OOW in order to learn more about the project and explore potential strategic fit.
