Polenergia, Equinor Tap DeepOcean for Geophysical Surveys Offshore Poland

January 30, 2025, by Adnan Memija

Norway-headquartered DeepOcean has been awarded a subsea survey contract for the Bałtyk 2 and Bałtyk 3 offshore wind projects in Poland, which are jointly developed by Equinor and Polenergia.

Under the contract, DeepOcean will carry out geophysical seabed surveys of the export and inter-array cable corridors, utilising a dedicated survey remotely operated vehicle (SROV).

The work scope also includes surveys to map the seabed for potential unexploded ordinances (UXO).

DeepOcean’s survey vessel Edda Flora will be mobilised for the main scope, while Poland’s MEWO will serve as a subcontractor for UXO surveys, utilising the vessel Amber Cecilia.

“A dedicated survey ROV will have significant efficiency gains when compared with the alternative of using slower work class ROVs configured with a survey sensor payload. We look forward to supporting Equinor and Polenergia on these important offshore wind projects,” says Øyvind Mikaelsen, CEO of DeepOcean.

The Bałtyk 2 and Bałtyk 3 offshore wind farms are set to be built in the Polish sector of the Baltic Sea, approximately 37 and 22 kilometres from the coastline near Ustka and Łeba.

The projects will feature 100 SG 14-236 DD wind turbines, which will be installed by Cadeler. The export and inter-array cables for the two wind farms will be supplied by Greece’s Hellenic Cables.

Regarding the onshore cables, Poland’s Tele-Fonika Kable recently delivered the first batches to Equinor and Polenergia.

According to the developers, the two projects will generate a combined capacity of 1,440 MW, enough to power over two million households with renewable energy.
