The mission is to raise awareness of the oceans’ potential, pioneer marine project development and collaborate with partners to build a sustainable blue economy and communities. Simply Blue Group has a portfolio of floating wind power projects of more than 10GW.

What is an offshore wind farm?

An offshore wind farm is a collection of wind turbines. Each wind turbine is either fixed directly to the seabed or is attached to a floating foundation on the surface, which is then anchored in position. Wind forces cause the turbine blades to rotate creating large amounts of electricity which is then transferred to shore via a subsea cable.

What are the advantages of offshore wind?

Wind conditions offshore are much more favourable than on land with a stronger and more consistent wind resource. In addition, taller turbines can be used offshore allowing a single turbine to generate as much energy as three or even four onshore turbines.

What is floating offshore wind? (FOW/FLOW)

Floating offshore wind projects involve developing an array of offshore turbines supported on floating substructures that are moored and anchored to the seabed. The turbines generate electricity which is typically fed back to shore via an export cable.

What are the advantages of FOW/FLOW?

Floating offshore wind technology allows turbines to be located farther from shore, in waters too deep to make fixed bottom alternatives economically viable, further minimising visual impacts.

Technology

How are floating wind turbines fixed in place?

Foating wind turbines can be deployed in varying water depths due to the flexible design that can utilise a keel or spar arrangement depending on the water depths or sea condition requirements. There are currently several types of different floating turbine technologies (see below). The floating units are secured to the seabed via a mooring arrangement connected to several anchor points. The mooring and anchor system is designed to resist the wave loading that the structure experiences from the surrounding environment.

What impact will extreme weather events have on turbines?

Comprehensive studies are undertaken during the design of offshore energy installations to understand historic and future weather patterns. Offshore wind farms are designed, constructed, and operated in consideration of extreme weather events and operational ranges of the devices.

How will the floating wind farms be connected to the mainland?

Floating wind farms will be connected to the mainland electricity grid via underwater cables.

Skidbladner

What is the proposed scale of the Skidbladner floating wind project?

The proposed size of Skidbladner is 111 floating wind turbines just over 20 km north of the island Gotska Sandön.

What is the timeline for the Skidbladner floating wind project?

In 2021 and 2022 the project conducted its preliminary studies. In the spring of 2023, public consultations were carried out. Subsequently, surveys, investigations, environmental impact assessment and the permit application will be completed. Another critical factor is the ability to connect to the electricity grid. Once operational, the wind farm is expected to have a life expectancy of approximately 35 years.

How large are the wind turbines for Skidbladner floating wind and how many will there be?

The floating wind turbines will be a maximum height of 360 meters and there will be 111 in total.

What survey activity will be carried out for the Skidbladner floating wind project and what is the survey timeline?

Extensive survey works are carried out during the environmental impact assessment, it includes but is not limited to geophysical, geotechnical, marine and environmental investigations. These investigations will be summarized and evaluated in the EIA report which is due to be completed in 2024. The aim of this is to minimise and prevent environmental impact.

Herkules

Wellamo

What is the proposed scale of the Wellamo floating wind project?

The proposed size of Wellamo Floating Wind is 100 floating wind turbines.

What is the timeline for the Wellamo floating wind project?

Wellamo's preliminary investigations began in 2022. These included project area mapping and an evaluation of area suitability. Subsequently, in 2023 the project began its environmental impact assessment (EIA) which will continue until 2024.The Wellamo project will be installed in the first half of the 2030s and first power is aimed at 2035. Once operational, the wind farm is expected to have a life expectancy of approximately 35 years.
