Baltic Offshore

Baltic Offshore is a Swedish private submarine cable contractor headquartered in Kalmar, formed as an independent company in 2006 but rooted in a sea cable heritage dating back to 1853, when the Kongl. Elecktriska Telegraf-Werket began building national telegraph infrastructure. Its activities build on the former Televerket sea cable unit, which from the early 1960s expanded telecom networks along the Swedish coast and internationally and later contributed to power interconnectors and early offshore wind-related installations. The company operates the cable ship CS Pleijel, refined over time into an advanced DP II-class vessel with systems for the simultaneous installation of multiple cables, supported by a fleet of specialized work boats, rafts and mobile equipment. In 2017 Seaworks Kabel AS, a long-standing Norwegian submarine cable service provider with more than 1,000 offshore and inshore telecom and power cable installations and two dedicated vessels, Nordkabel and Fjordkabel, joined the Baltic Offshore group, extending its operating area and capabilities. Baltic Offshore’s core business covers installation, maintenance, repair and protection of submarine power and telecom cables, including turnkey delivery. Reference projects include fibre optic links between Germany, Bornholm and Sweden, between Gotland, Öland and Bornholm, and between Malmö and Copenhagen; turnkey cable supply and installation for the Kårehamn offshore wind farm; HVAC and HVDC connections and reinforcements such as a 420 kV cable installation and protection between Beckomberga and Bredäng, 245 kV circuits in Edsviken, the 80 kV HVDC Åland–Finland and 70 kV HVAC Iceland–Westman Islands connections; and multiple 24–110 kV distribution cables for Swedish and Norwegian utilities. In Estonia, the company has been contracted for 110 kV AC submarine cables across the Väike Väin and Suur Väin straits, involving pre-trenching, float-out installation in very shallow waters, and trenching and protection works. Baltic Offshore also participates in projects related to offshore wind farm infrastructure and biodiversity and engages in initiatives to strengthen energy security and grid reliability in the Baltic Sea region.
