Welcome to Seawind Ocean Technology

A leading turnkey supplier of floating & bottom fixed offshore wind assets

Seawind is developing  innovative floating offshore wind solutions to support global decarbonisation.

Based on original research and development work by NASA and Hamilton Standard (today United Technologies), our Seawind 6 and Seawind 12 floating offshore wind turbines and integrated concrete floating foundations are patented and achieved Technology Readiness Level 5, certified by DNV. 

Innovative design
  • Twin-bladed rotors with teetering hinge and yaw control inspired by helicopter technology
  • No blade pitching, only yawing to deal with wind direction and speed
  • Design achieves lower torque and lighter drivetrain for higher rotation speeds, achieves low fatigue and longer life due to the teetering hinge
  • Only one mechanism to deal with wind direction and speed
Lowest green energy cost
  • 25-35% LCOE cost advantage* compared to state of the art 3-blade technologies
  • Optimised costs for manufacturing, operation and maintenance
  • Seawind technology is highly competitive against fossil fuel and renewable energy technologies
  • Reduced cost as the turbine and the support structure are designed as one system

Straightforward deployment
  • Macro components delivered and assembled by blue-chip supply chain partners
  • Towed out to sea for installation, without requiring cranes or heavy vessels 
  • 25% lighter nacelle weight* compared to 3-blade technologies
  • Less parts due to no blade pitching and lightweight turbine head

Unlocking green hydrogen
  • Supports energy transition global agenda
  • Stable and cost-effective electricity source for green hydrogen production
  • Lower intermittent power supply
Safe maintenance
  • Safe access by helicopter through helideck
  • Additional safe access by sea
  • Spacious nacelle for all O&M operations
Environmental responsibility
  • Less materials, reduced carbon footprint
  • No rare-earth metals 
  • No harmful pile driving at sea
Solutions for every need

Offshore wind solutions meeting the needs of large and smaller installations to globally support decarbonisation

Large wind farms

Our 12MW turbine solution is a cost-effective alternative for the development of large wind farms. Its unique design, and its assembly and installation methods should potentially result in a LCOE of €40/MWh by 2040

Smaller ‘higher wind speed’ wind farms

Seawind 6 MW turbine solution is perfect for small islands and coastal communities wishing to generate their own supply of low carbon renewable energy. Our solution can tolerate wind speeds upto 325km/h, making it also an ideal solution for cyclonic regions.

Energy transition – including green hydrogen

Seawind is dedicated to helping major power consumers decarbonise. Seawind is working on  future new green hydrogen production solutions that should offset or replace their carbon footprint.

Wind market challenges

Thanks to reduced green energy cost solutions, Seawind will unlock new untapped markets

The offshore wind’s contribution to the wider energy mix will increase as we get closer to 2050, reaching aout 40% of total wind production with a significant scaling of global installed offshore wind capacity, from 29 GW in 2019 to 1,748 GW in 2050. Floating offshore wind is anticipated to generate 15% of all offshore wind energy, contributing 264 GW by 2050 versus only 0.1 GW in 2021. (Source: ‘DNV – Floating Offshore Wind: the next five years ‘. February 2022)

Offshore wind will grow from a small base to account for more than 60% of ocean energy capex in 2050. Over the same timeframe, the Oil & Gas industry will shrink from 80% of total ocean energy capex to just 25%. By 2050, offshore wind will provide about as much energy as offshore oil, the production of which would shrink by 50% compared with 2019 levels. In 2018, the total ocean energy operating expenses amounted to $333 billion (with offshore wind operating expenses share just under 2%) and they may rise to $370 billion in 2050 with an estimated offshore wind operating expenses share at 21%.

Ocean Offshore Coalition for Energy and Nature (OCEaN) Member

OCEaN is a coalition of NGOs, wind industry and TSOs, joining forces to cooperate on the sustainable deployment of offshore wind energy. Seawind has ecology in its DNA; we design, build and operate so that the energy produced by our floating offshore units has no impact on marine habitats. For this reason we have been invited to the Offshore Coalition for Energy and Nature. Seawind is member since 2020. https://offshore-coalition.eu/

Solar Impulse Efficient Solution Label

Seawind’s floating wind turbine tech is recognised as one of the 1000+ clean and profitable solutions by Bertrand Piccard’s Solar Impulse Foundation. In this context, Seawind’s Offshore Floating Wind Turbine system has been awarded the “Solar Impulse Efficient Solution” Label by the Solar Impulse Foundation in September 2020. https://solarimpulse.com/label
