Based in Sweden, UW-Tech AB is a specialized contractor dedicated to underwater inspection, construction, and maintenance. The company operates as a technical partner for the maritime, energy, and civil infrastructure sectors, providing solutions for environments that are hazardous or inaccessible to standard crews. Their core identity revolves around the integration of traditional commercial diving with advanced robotic technologies, allowing them to execute complex subsea tasks ranging from structural repairs to high-definition data capture.
A significant portion of the company’s operations supports the maritime logistics industry, specifically through the maintenance of port infrastructure. Working with major transit hubs such as the Port of Gothenburg and the Port of Stockholm, UW-Tech AB conducts critical integrity assessments of quays, piers, and underwater foundations. To execute these inspections, the company employs a fleet of Remotely Operated Vehicles (ROVs) equipped with sonar and video capabilities. These robotic systems enable the team to inspect confined spaces or deep-water structures, providing asset owners with detailed visual evidence and structural data without the need for dewatering or dry-docking.
The company distinguishes itself through advanced hydrographic surveying and digitization capabilities. Using multi-beam sonar and underwater photogrammetry, they create precise 3D models of seabeds, ship hulls, and submerged tunnels. This technology facilitates accurate mapping for navigation safety and construction planning. Beyond inspection, their commercial diving division performs heavy underwater construction, including cutting, welding, and concrete repair, directly supporting the longevity of marine assets.
Environmental remediation represents another key operational pillar. The company utilizes specialized suction dredging techniques designed to minimize sediment dispersion and turbidity, which is crucial when working in contaminated harbors or sensitive waterways. Their approach often involves pumping dredged material into geotextile containment bags, ensuring safe disposal and compliance with strict environmental regulations. While their headquarters in Falun anchors them in the Swedish market, their technical proficiency supports a broad client base, including hydropower operators and municipal authorities requiring management of water-filled assets. By combining human expertise with autonomous systems, the company ensures the operational continuity of essential underwater infrastructure.
