This is a fundamental process for assessing the state of conservation and functionality of submerged components of maritime infrastructure. This service includes the inspection of piles, fenders, docks, moorings, pontoons, vessel hulls, and metal structures exposed to the effects of saltwater and ocean currents.

Professional divers, equipped with cameras, high-intensity lights, and measuring tools, visually record structural conditions and detect signs of corrosion, erosion, cracks, detachments, or the presence of marine organisms that could compromise the integrity of the material. The results obtained are documented in detailed technical reports, which allow for the planning of preventive or corrective maintenance interventions, extend the useful life of the facilities, and ensure the safety of maritime and port operations.
