Orlen Group has completed preliminary seabed surveys for its Baltic East offshore wind farm in the Polish Baltic Sea.
The company said the four-month campaign was conducted by a consortium of Polish firms – Orlen Petrobaltic, Geofizyka Torun and MEWO – covering more than 1000km of seismic lines along with soundings and boreholes.
Orlen Neptun president Janusz Bil said: “Seabed investigations are one of the key stages in developing our offshore wind farm project.”
He added: “The work in the Baltic was carried out by a consortium of three Polish companies, which shows the growing readiness of the Polish supply chain to provide high-quality services to the offshore wind energy sector.”
Bil said: “The offshore surveys were conducted to the highest standards and best practices, keeping environmental impact to a minimum. The results will allow us to move efficiently into the next stages of project delivery.”
Orlen said the surveys began in late June and lasted more than 15 weeks using three specialist vessels operating across the full project area.
Geofizyka Torun performed multichannel 2D seismic surveys, while MEWO conducted unexploded ordnance searches identifying dozens of magnetic anomalies to ensure safe drilling.
Orlen Petrobaltic completed over 1200 metres of geotechnical boreholes and soundings, reaching depths of up to 80 metres below the seabed. Laboratory analysis of soil samples is now under way alongside interpretation of seismic results.
The company said the data will support design work, geological modelling, and future development planning for the Baltic East project, which has preliminary grid connection conditions and key construction permits in place.
Orlen said Baltic East has potential for close to 1GW of capacity, capable of supplying about 1.25 million homes, and will follow the 1.2GW Baltic Power project due online in 2026.
Together with four additional Baltic licences, ORLEN said its offshore wind portfolio totals around 6.4GW, contributing to its goal of 12.8GW of renewable capacity by 2035.
