UK-based power systems developer Rolls-Royce has signed a contract worth £11m to design and deliver equipment to two offshore vessels for Brazilian ship owner, Asgaard Navegação.

The two type UT 535 E oil spill response vessels (OSRV) will be built at the Brazilian shipyard Aliança Industria Naval e Empresa de Navegacao, which is a subsidiary of Fischer Group.

Under the contract, Rolls-Royce will deliver design and equipment packages, including propulsion systems, thrusters, DP systems, power electrical systems, automation and control systems, deck machinery, and MTU engines.

The two vessels, which are capable of transferring extracted oil for proper onshore disposal, feature systems designed to prevent damage from oil spills.

The two vessels for Asgaard are expected to be delivered in 2015, with an option to build two more.

Rolls-Royce offshore president, Anders Almestad, said that working closely together with Asgaard during the construction of the advanced vessels will be vital.

"The two vessels for Asgaard are expected to be delivered in 2015, with an option to build two more."

"This order also marks the continuation of a long cooperation between Rolls-Royce and Aliança, and underscores our strength and capabilities in the Brazilian market," Almestad added.

The Aliança shipyard, which is owned by Companhia Brasileira de Offshore (CBO), has built ten Rolls-Royce vessels earlier for CBO’s own fleet.

In December 2012, Rolls-Royce received an order worth £100m from Atlântico Sul to deliver integrated power and propulsion systems for seven offshore drilling vessels to Petrobras.

To be built at the Atlântico Sul Shipyard in Brazil, each of the seven vessels will be equipped with six large thrusters and six Bergen diesel generator sets.
