Northrop Grumman Corporation’s (NYSE: NOC) Sperry Marine business unit has been awarded contracts to supply bridge navigation systems for four new offshore supply vessels to be built in Brazil.

The four multipurpose platform supply vessels, designed by Rolls-Royce, will be built at the Estaleiro Aliança shipyard near Rio de Janeiro for Companhia Brasileira de Offshore (CBO). They will be placed on long-term charter with Petrobras, the Brazilian state oil company, to provide support services for offshore oil platforms.

The scope of supply includes radars, autopilot, speed and heading sensors and other navigation systems. Sperry Marine’s sales and service representative in Brazil, Vision Marine Ltda, will be responsible for installation, commissioning and servicing the equipment on the vessels.

Last year, Sperry Marine received orders to supply the same navigation packages for four similar vessels at the same shipyard.

J. Nolasco DaCunha, vice president of Northrop Grumman Sperry Marine, said, “These new orders for four additional ships build on our excellent working relationship with Rolls-Royce and CBO and validate our position as a preferred supplier of navigation technology for platform supply vessels in Brazil’s rapidly growing offshore oil sector.”

Created in 1978, CBO is part of Fischer Group, a Brazilian conglomerate that operates in several industrial segments and countries. The Estaleiro Aliança shipyard, acquired by CBO in 2004, specializes in construction of support vessels for the offshore oil industry.
