Ilmatar Offshore contracts OWC for conceptual design of Finnish projects

Ilmatar Offshore has contracted OWC to conduct a conceptual, technical design for two offshore wind projects north of Åland, Finland.

During autumn 2022, seabed surveys were performed on Ilmatar Offshore's project areas Stormskär and Väderskär, north of the Åland Islands, totalling approximately 570 km2. The geophysical surveys saw the areas have highly variable depth conditions and a mix of hard and soft bottom sediments.

UK-based OWC is now tasked to develop a conceptual design for the Stormskär and Väderskär sites. Based on the data from the surveys, OWC will investigate where the turbines can be placed and what types of foundations are suitable in which locations.

The study also includes a variety of other criteria that influence the final layout of the wind farm, including wind conditions, ice conditions, turbine size selection and hub height. Possible cable routes inside and outside the project area are identified, as well as criteria for port operations, potential ports and logistics solutions for the different stages of the wind farms, such as the construction and operational phases.

Stefan Husa, Head of Maritime Spatial Planning at Ilmatar Offshore, said: “OWC has extensive experience in successfully completing offshore wind projects in Europe, the Americas, and Asia. They have a strong team of specialists and all the expertise required to produce the technical base for our environmental impact assessment.”

Christian Apeah, OWC's Head of Independent Engineering, said: “We are delighted to support Ilmatar in its activities growing offshore wind in Åland. As the region is picking up speed on the offshore wind sector, it is also beneficial for us to be among the first movers.”

Regarding the environmental conditions, Apeah continues: “Environmental conditions such as icing and soil of this far north region of the Baltic Sea make this project particularly challenging. We have mobilised our most experienced engineers and consultants to fully support Ilmatar in developing this project.”

OWC's final report will be delivered before the summer and form the basis for further studies in the environmental impact assessment process.
