What Sea E Mar Servicos Tecnicos Subaquaticos does

Sea & Mar Serviços Técnicos Subaquáticos is a privately held Brazilian underwater technical services company founded in 1988 and headquartered in Serra, Espírito Santo. The company provides specialized underwater maintenance, inspection, and construction services for vessels, ports, and industrial maritime infrastructure, operating across six Brazilian coastal ports: Vitória, Tubarão, Praia Mole, Ponta do Ubu, Jurong (Aracruz), and Açu (RJ).

Its service portfolio spans three core lines: ship maintenance (hull cleaning, propeller polishing, rudder servicing, submerged welding and cutting, and underwater inspections with photographic reports); port services (channel and drainage works, reservoir surveys, rock-channel and pipe inspections, underwater power-line maintenance, explosive cold and hot dismantling, non-destructive testing, computerized bathymetry, and Bade-Wirth foundations); and specialized services (waterproofing, cathodic protection, blasting, epoxy application, submerged concrete, search and rescue, dredging, and thickness measurement). The underlying technology is conventional commercial diving equipment paired with inspection tooling (jet-probe, bathymetry, photographic reporting).

The business operates on a B2B professional-services model, generating revenue through project-based and recurring maintenance contracts sold directly to enterprise clients. Pricing is not publicly disclosed and quotes are issued per project based on scope, depth, and duration. Sea & Mar has no disclosed external funding, operates with approximately 6 employees, and relies on direct sales and long-standing industry reputation as its primary go-to-market, with no formal marketing channels beyond its company website.
