Shell and Innogy agree investment on €18m floating wind project

Energy giants Shell and Innogy have teamed up with Stiesdal Offshore Technologies (SOT) to invest in an €18m demonstration project they hope could slash the costs of installing floating wind turbines.

The trio yesterday announced the final investment decision on the TetraSpar floating wind project, firing the starter gun on work to install a turbine with a floating foundation off the Norwegian coast.

The plan is to create a turbine foundation featuring a modular structure, which would be constructed from tubular steel and incorporate a suspended keel. The companies said that because the design can be assembled on land and towed fully constructed out to sea, it should deliver significant cost savings compared to current designs for floating turbines.

Innogy now expects the turbine to enter its testing period by 2020. The firm has a 33 per cent stake in the project, while Shell has increased its share from 33 per cent to 66 per cent and SOT holds the remaining one per cent stake.
