Stockholms Reparationsvarv AB, which trades as Stockholm Repairyard, works from the island of Beckholmen in central Stockholm. Ship repair has gone on there since the seventeenth century, and the island is named after the pitch works that once stood on it. The Gustav V dry dock was built more than a century ago for the Swedish Navy, which kept a presence on Beckholmen until the 1960s, when its docking moved to the Musko base. The present company took the facility over and restored it at the start of the 1990s and has run it since 1992. About a hundred vessels a year are handled.
This is a repair, maintenance, modification and life-extension business rather than a builder. Work runs from routine dockings and emergency repairs to rebuilds, navigation system upgrades, environmental compliance work and energy efficiency measures. Coating systems are chosen for year-round service in Lake Malaren, the Saltsjon and the Baltic, steelwork runs from anode renewal to major renovation and damage repair, and there are mechanical and electrical teams of the yard's own. Sonihull ultrasonic antifouling systems, which need no docking, are installed across the Nordic region.
Two graving docks are in use. The Gustav V dock takes vessels of up to 170 metres; its original gate, close to a century old, has been replaced by a new one built by the Dutch yard Ravestein and towed from Rotterdam over nine days. Ostra dockan is the smaller of the two. Berths alongside have 5 to 12 metres of water.
Two further businesses run from the same site. Mobile Ship Service sends equipped vehicles and teams to the vessel for electrical, mechanical, steel and painting work, on board or ashore, anywhere between Gavle and Oxelosund, and a chandlery supplies spare parts, paint, tools, provisions and safety equipment in the Stockholm area. Recent work includes the modification of HMS Trosso and the life extension of HMS Loke, both in 2022, repairs aboard Viking Line ships alongside and under way, renewal of the bottom plating of the 120-year-old steamer S/S Norrtelje, and a technical upgrade of the Swedish Transport Administration ferry Neptunus covering energy efficiency and preparation for future autonomous operation. In December 2025 the yard signed a letter of intent with Navantia, together with Oresund Drydocks, for through-life support of Sweden's planned Lulea-class frigates.
