Jupiter IV Pusher | Baudouin Case Study

The Jupiter IV pusher is owned and operated by Transportes Jupiter and is dedicated to crude oil transportation along the Amazon River basin.

Operating on one of the region’s most demanding inland waterways, the vessel transports crude oil from Bretaña and Ucayali to Manaus, Brazil, playing a key role in supplying energy to remote Amazonian regions.

The vessel is designed to push four barges of 30,000 barrels each, enabling a total transport capacity of 120,000 barrels per voyage.

The river distance between Bretaña and Manaus is approximately 1,840 km, with a full round trip typically completed in 28 days. Operating at a cruising speed of around 8 knots, Jupiter IV must deliver continuous thrust, high reliability and endurance over long operating cycles, often far from major service hubs.

For this project, Transportes Jupiter selected Baudouin as its propulsion engine partner, equipping Jupiter IV with two Baudouin 6M33.2 marine propulsion engines.

Jupiter IV is powered by two Baudouin 6M33.2 marine propulsion engines.

This choice reflects Transportes Jupiter’s confidence in Baudouin’s marine propulsion range, which is engineered for demanding commercial and inland navigation applications.

The 6M33.2 engines deliver the torque and robustness required for heavy pushing duties, ensuring stable propulsion performance when handling fully loaded barge convoys.

Each Baudouin 6M33.2 engine delivers 1200 HP at 1800 rpm.

The engines are designed to support continuous heavy-duty operation while maintaining fuel efficiency and controlled operating temperatures, even in tropical river environments.

For a pusher workboat operating on long Amazon River routes, this balance of power, endurance and efficiency is essential.

Since entering service in October 2024, Jupiter IV has demonstrated reliable performance across long-distance Amazon River operations.

Its iron hull construction, combined with the robust Baudouin propulsion package, enables safe and efficient crude oil transport to multiple destinations, including Manaus and Belém, extending toward the Atlantic coast.

This application requires propulsion engines that can operate reliably over long cycles, with limited access to major maintenance facilities.
