Fiellberg Oy

Fiellberg Oy is a specialized engineering and manufacturing company based in Finland, recognized for its expertise in high-performance hydraulic solutions for the marine, offshore, and heavy industrial sectors. Headquartered in Vantaa, the firm represents a direct continuation of the region’s extensive mechanical engineering heritage. By integrating the technical archives and retaining the experienced workforce of predecessor operations, Fiellberg Oy has secured a position as a knowledgeable supplier with roots extending back over sixty years in the Finnish hydraulic industry. The company’s core identity revolves around the design and production of heavy-duty hydraulic cylinders, which serve as critical actuation components in the maritime field. Fiellberg Oy engineers systems specifically built to endure the harsh, corrosive conditions of open-sea environments. Their products are frequently utilized to drive massive cargo access equipment, including heavy hatch covers on bulk carriers, complex stern ramps on Roll-on/Roll-off (RoRo) vessels, and bow visor systems. The company provides the mechanical force necessary to operate watertight doors and other essential movable ship structures. Beyond standard commercial vessels, the company extends its operations into the offshore energy and dredging markets. Their manufacturing scope includes robust cylinders for deck cranes, compensation systems, and harbor machinery where failure is not an option. Fiellberg Oy distinguishes itself by offering both a standardized marine cylinder series and fully customized solutions tailored to the specific architectural requirements of a ship or rig. To support the global shipbuilding market, the company employs a strategic operational model. While high-level engineering, product development, and quality management are centralized in Finland, Fiellberg Oy owns and operates a manufacturing subsidiary in Dalian, China. This facility enables efficient logistics for Asian shipyards while strictly adhering to the manufacturing standards set by European engineering teams. The company oversees the entire production lifecycle, from precision machining and welding to final pressure testing, ensuring compliance with major international maritime classification societies. Through this blend of Nordic engineering precision and global manufacturing capacity, Fiellberg Oy maintains a vital role in the marine equipment supply chain.
