What Belov does

Belov (legal name Belov Engenharia S.A.) is a privately held Brazilian marine and offshore engineering group founded in 1981 by Aleixo Belov and headquartered in Salvador, Bahia. The company provides an integrated stack of services across port engineering, underwater civil works, naval shipbuilding, hydrographic and geophysical survey, diving and ROV operations, vessel chartering, and offshore engineering for the oil and gas industry. Operations are anchored by an owned shipyard in Simões Filho (Baía de Aratu) with dry-docking, manufacturing, and decommissioning capabilities, supported by bases in Macaé and Guapimirim in Rio de Janeiro state.

The company's core technical assets include DP-2 rated diving support vessels (Belov Humaitá, Belov Amaralina, Belov Cidade Ouro Preto), an OTSV (Belov Mares), the Belov Piatã dredge, and surveying equipment such as multibeam and single-beam bathymetry, side scan sonar, sub-bottom profilers, and pipe locator/GPR systems. Belov holds exclusive Class A underwater welding certification in Brazil, IMCA membership covering diving and ROV services, RINA classification society approvals for newbuilds, and Centro de Hidrografia da Marinha registration. Vessels built at the Belov shipyard have won three international awards (2020 and 2023).

Belov operates a B2B enterprise field-sales model, selling directly to oil and gas majors (Petrobras, Shell, Chevron, Equinor, Modec, SBM Offshore, BW Energy), port authorities (Codeba, Tecon Salvador), shipping and logistics firms (Transpetro, SAAM Towage Brasil, Hidrovias do Brasil), mining and commodity logistics players (Vale, ADM, COFCO INTL), and the Marinha do Brasil. Revenue is generated through professional services contracts, hardware sales (vessel construction, chartering of owned fleet), and consortium arrangements for large infrastructure projects, with quote-based pricing on custom engineering work. The company is founder-controlled, with no disclosed external institutional investors, and is currently executing an R$70 million+ shipyard expansion via Fundo da Marinha Mercante that will double production capacity to 11,000+ tons/year.
