Bladt Industries and Semco Maritime are awarded EPCI Contract for the Baltic Power OSS project

The Baltic Power offshore wind farm project, a joint venture of ORLEN Group and Northland Power Inc., has awarded the EPCI contract to Bladt Industries and Semco Maritime for the two offshore substations for the Baltic Power project after naming the consortium a Preferred Supplier back in September 2022.

12 October 2023

A primary sub-contractor, ISC Consulting Engineers, has already successfully completed much of the engineering scope, both for the substations as well as for the monopiles and transition pieces, which will also be supplied by Bladt Industries.

The two substations will be constructed and established in the coming years, with final commissioning planned for early 2026, as key components of the electrical infrastructure for the Baltic Power offshore wind farm consisting of 76 wind turbine generators, each with a generating capacity of 15 MW.

Each substation will be a 2.5 thousand-tonne steel structure standing on foundations and rising about 20 meters above the sea level.

Following the EPCI contract signing, the consortium of Semco Maritime and Bladt Industries, supported by ISC Consulting Engineers, now initiates the execution of the project by proceeding with the detailed design, procurement, construction and commissioning of the two offshore substations.

The Baltic Power wind farm will be erected approx. 23 kilometres off the shore, near Łeba and Choczewo. When completed, the Baltic Power offshore wind farm will be able to supply more than 1.5 million households with clean power.
