Norwegian seabed-to-surface engineering contractor Subsea 7 S.A. (SUBC.OS) Thursday said it has inked a $1 billion deal with Petroleo Brasileiro SA (PBR), known as Petrobras, for deepwater development offshore Brazil.

The project includes engineering, procurement, installation and pre-commissioning of four decoupled riser systems.

Development is for the Pre-Salt deepwater Guara and Lula North East Areas located in the Santos Basin, offshore Brazil, in water depths of approximately 2,200 meters.

Project management work is to start immediately and offshore installation is scheduled to commence during the second half of 2012, the firm said.

Subsea 7 shares closed at NOK143.30 Wednesday.
