Ilmatar hires OWC for conceptual design of Aland offshore wind project

Ilmatar Offshore, a subsidiary of Finnish independent power producer Ilmatar Energy Oy, today said it has engaged UK-based consultancy OWC to develop a conceptual design for two sites north of Aland, Finland.

Ilmatar carried out seabed surveys in relation to its Stormskar and Vaderskar areas in the autumn of 2022. The sites cover about 570 sq km in total and according to a previous announcement could host a roughly 2.1-GW offshore wind project.

The geophysical surveys showed very different depth conditions and a mix of hard and soft bottom sediments, the company said. OWC's study will involve potential locations for the turbines, suitable foundations, as well as other factors influencing the wind farm’s layout such as wind conditions, ice conditions, turbine size selection and hub height.

“Environmental conditions such as icing and soil of this far north region of the Baltic Sea make this project particularly challenging,” noted Christian Apeah, OWC’s head of independent engineering.

OWC, part of Oslo-listed ABL Group ASA, will be ready with its report before the summer. It will inform further studies in the environmental assessment process.
