Girassol Angola Block 17– Critical Future Upgrade of an FPSO

• Satellite reserves Jasmin, Rosa, Lirio, Cravo could

equal the initial Girassol field development.

• Foresight in FPSO location, deck layout, and initial riser configuration to accommodate

some future expansion. Jasmim tieback straightforward.

• Scale of offshore upgrade to accommodate Rosa tie back is unprecedented

• 5500te additional equipment, liquids capacity increased from 300mbd to 500+ mbd

• Phase 1 Rosa Risers 4P+2WI+2GL, Optional Phase 2 Lirio/Cravo 2P+2WI+2GL
