Based in the Cromarty Firth area of Scotland, Caldive functions as a specialized marine contractor and commercial diving provider. The company, headquartered in Invergordon, has developed an operational profile centered on subsea intervention, marine civil engineering, and offshore support services. Rather than functioning solely as a labor supplier, the organization manages comprehensive marine projects that require the integration of surface logistics with underwater technical tasks. The firm serves a diverse client base that spans the energy transition, infrastructure, and utility sectors, reflecting the changing demands of the modern maritime economy.
A significant portion of the company’s activity is dedicated to the inspection, repair, and maintenance of submerged structures. This work often involves deploying diving teams to assess the integrity of harbor piling, bridge foundations, and subsea cabling. In the renewable energy sector, the company supports offshore wind developments, providing essential services during both the construction and operational maintenance phases of wind farm lifecycles. Similarly, the firm retains a presence in the oil and gas industry, offering diving support for platform maintenance and pipeline inspection. Beyond energy, the organization undertakes complex civil engineering tasks, such as underwater concreting, cutting, and welding, often in challenging environmental conditions characterized by strong tides or poor visibility.
To facilitate these operations, Caldive maintains and operates a fleet of specialized vessels. These marine assets range from workboats and multi-cats to dedicated dive support vessels equipped to sustain diving teams for extended durations. The fleet acts as the primary platform for survey operations and logistical transport, ensuring that equipment and personnel can reach remote or difficult-to-access marine sites. The company also provides safety boat services, ensuring the protection of personnel working over or near water on large-scale construction projects. Operational procedures are structured around established maritime safety standards, with the organization adhering to rigorous guidelines for commercial diving and vessel management. Through its combination of vessel management and subsea expertise, Caldive acts as a critical support link in the UK and European maritime supply chain, enabling the continued operation of essential coastal and offshore infrastructure.
