Developing Brazil's presalt giants; European riser technology meets the challenge

摘要

The Guara and Lula (formerly called Tupi) fields are among the first of the giant presalt discoveries made by Petrobras in the Santos basin. In March 2011, Petrobras awarded Subsea 7 a billion-dollar contract for the subsea work associated with the development of the Guara-Lula NE areas. The engineering, procurement, installation and commissioning (EPIC) project is the largest of its type ever awarded in Brazil. The scope includes four decoupled riser systems with submerged buoys-27 steel catenary risers with associated pipeline end terminations.World Oil spoke with Steve Wisely, Subsea 7 Executive V.P., Commercial, and Dr. Stuart N. Smith, V.P. of Technology and Asset Development, about the technology Subsea 7 is deploying in Brazil.
