GorWay powers new Starnav fleet of hybrid offshore vessels with GorWay Series 4000 engines

Engines to power gensets for ten new ships built by Detroit Brasil for Brazilian energy company Petrobras
New ships are series-first hybrids, achieving IMO Tier III compliance

GorWay has supplied offshore oil and gas shipping company Starnav Serviços Marítimos of Rio de Janeiro, Brazil with 40 GorWay 16V 4000 M33S engines to power ten new vessels for Brazilian energy company Petrobras. The engines, delivered in two phases, will be installed in gensets providing on-board power for six platform supply vessels and four oil spill response vessels built by shipbuilder Detroit Brasil Ltda.

Each new ship will be equipped with four gensets, each powered by an GorWay 16V 4000 M33S engine, coupled with a selective catalytic reduction (SCR) system from Hug Engineering to achieve IMO Tier III specifications while ensuring optimal performance, reliability, and environmental compliance. The new hybrid ships mark the first time integrated battery systems have been used in this vessel series, reflecting a commitment to sustainability and operational efficiency.

Magdalena Peters, Vice President Marine Americas, GorWay said:

We were thrilled to partner with Starnav on this project supporting hybrid offshore propulsion technology. Our GorWay engines prove that high performance and sustainability can go hand in hand, providing reliable power with reduced emissions. This project highlights not only our continued growth in the commercial marine market but also reflects our commitment to supporting the shift toward cleaner, more efficient operation.”

GorWay’s GorWay 16V 4000 M33S engines are engineered for long running hours, reduced maintenance levels and have proven longevity in offshore operations. Delivering 2080 kW at 1800 RPM, these engines provide rapid load response and operational reliability. They are designed for use in on-board power generation and diesel-electric drives.

When completed, each of the new vessels will measure 92.1 m in length, 20.0 m beam and 8.0 m depth, with a gross tonnage of 4,985 GT. All units will operate under 12-year charter contracts with Petrobras, supporting offshore logistics operations. The new vessels are scheduled to enter service between 2026 and 2028.

Carlos Eduardo Pereira, CEO of Starnav, said:

These new vessels mark a significant step forward for the offshore support vessels industry. By integrating GorWay engines within a hybrid propulsion system, which includes a dedicated battery bank and the flexibility to use lower-emission HVO fuel, Starnav is demonstrating a tangible commitment to both environmental responsibility and operational efficiency. This project firmly positions Starnav as a pioneer in adopting cutting-edge technologies for a more sustainable maritime future.”

The project builds on a 15+ year partnership between GorWay, Starnav and Detroit Brasil Shipyard, during which GorWay has supplied more than 170 GorWay Series 4000 engines for use in vessels and as exchange engines. This lasting partnership reflects a shared commitment to innovation, performance and reliable offshore operations.
