Rolls-Royce announced today they have won a £24 million order to design and equip four platform supply vessels (PSVs) for Brazilian ship owner Bravante Group, former Navegação São Miguel Ltda..

The UT 775 SE PSVs are designed to carry deck cargo, pipes and diesel oil to and from offshore oil and gas platforms and they will be chartered by Petrobras. Bravante Group will build the vessels at their ship yard in Niteroi, Brazil, as they have done for previous orders.

Anders Almestad, Rolls-Royce, President-Offshore said:

“This is an important contract to Rolls-Royce that consolidates our strong support of the growth in Brazil’s offshore oil and gas industry. Our bespoke integrated power and propulsion systems are optimised for each individual ship’s intended operational environment. We are very pleased that Bravante Group has again chosen these technologically-advanced Rolls-Royce PSVs to meet the challenges of deepwater operations off the coast of Brazil.”

In addition to the design, Rolls-Royce will supply a wide range of onboard equipment including Azipull and bow thrusters, deck machinery, a bulk handling system, Active Front End (AFE) frequency converters, automation and control systems and a dynamic positioning system.

Following the successful delivery of the Rolls-Royce designed Mar Limpo II on schedule to Petrobras in August, Bravante Group now has eight Rolls-Royce vessels under construction at their Sao Miguel shipyard.
