What Starnav Serviços Marítimos does

Starnav Serviços Marítimos is a Brazilian offshore vessel operator headquartered in Rio de Janeiro and founded in 2007 as part of Grupo Detroit. The company owns and operates a fleet of 18 Platform Supply Vessels (PSVs) supporting Petrobras' offshore oil and gas production across the Campos, Santos, and Espírito Santo basins, complemented by anchor handling, towing, oil recovery, and oil spill response services. Its operations are supported by four coastal bases in Rio de Janeiro, Santos, Vitória, and Salvador, and an in-house Starnav Training Center with bridge simulator and DP-2 certification capabilities. Vessels are built under the Detroit Brasil shipbuilding arm and powered through a long-running partnership with Rolls-Royce Power Systems (mtu), with the next-generation F3000-HX dual-fuel hybrid PSV fleet due to be commissioned between 2026 and 2028.

The business model is anchored by multi-year charter contracts with Petrobras, typically structured around 12-year tenors, providing predictable day-rate revenue tied to vessel utilization. Starnav is registered with Brazil's ANTAQ as a Brazilian Shipping Company (EBN) and operates under ISO 9001, ISO 14001, OHSAS 18001, ISM Code, ISPS Code, and ABS SVR certifications, which are gating requirements for participation in Petrobras tenders and for operating in Brazilian-flagged offshore logistics. Crew development is handled internally through the Starnav Training Center, reducing reliance on external academies and supporting continuity of qualified personnel across the fleet. The company is privately held, with no public revenue disclosure, and operates within a vertically integrated structure alongside Detroit Brasil for vessel construction and lifecycle maintenance.

Revenue is generated through vessel charter fees, with growth levered to fleet size, day rates, and contract renewals. The forthcoming hybrid PSV fleet represents a roughly 55% capacity expansion and is being procured to align with Petrobras' low-emission operational targets, signaling alignment between Starnav's capital deployment and the dominant customer's ESG roadmap. Customer concentration is structurally high, with Petrobras as the near-exclusive counterparty across the existing fleet, and revenue predictability is a function of long-tenor charter renewal cycles and Brazilian offshore capex activity.
