Petersen & Sørensen Motorværksted A/S is a Danish maritime service provider and shipyard known for its extensive technical capabilities in ship repair, engine maintenance, and mechanical engineering. Established in the early 1940s, the company has evolved from a local machine shop into a comprehensive maritime hub located in Svendborg on the island of Funen. Its strategic position near the Baltic Sea allows it to serve a diverse range of vessels, from commercial cargo ships and ferries to specialized offshore units.
The company operates from substantial facilities on Frederiksø, where it combines the functions of a modern shipyard with those of a high-precision machine workshop. Its infrastructure includes dry-docking and floating dock capacities that accommodate vessels of significant size for inspections, hull repairs, and class surveys. Beyond standard docking, the yard handles complex steel construction, offering welding and fabrication services that meet rigorous classification society standards. This enables the execution of major structural repairs, modifications, and new installations for both marine and heavy industrial applications.
A central pillar of the company’s identity is its deep expertise in propulsion and power generation. The workshops are equipped to handle the complete overhaul and renovation of marine engines, ranging from auxiliary units to large main propulsion systems. Technicians perform precision tasks such as cylinder liner honing, engine block grinding, and crankshaft alignment using advanced laser technology. The company acts as an authorized service partner for several major engine manufacturers, providing factory-standard maintenance and genuine spare parts. This technical proficiency extends to the refurbishment of propellers, shafts, and turbochargers, ensuring that vessels can return to operation with restored efficiency.
In addition to its maritime activities, Petersen & Sørensen Motorværksted A/S supports the land-based industrial sector by supplying and servicing backup power systems and generators. The workforce, comprised of skilled shipbuilders, blacksmiths, and marine mechanics, operates with a focus on flexibility, offering round-the-clock support to minimize downtime for clients. Through decades of adaptation and expansion, the company has maintained its status as a key technical partner in the Scandinavian maritime industry, recognized for its ability to manage complex mechanical projects and essential vessel maintenance.
