Total awarded Daewoo Shipbuilding and Marine Engineering (DSME) the engineering, procurement, and construction contract for the vessel’s moorings, hull, and topsides. In turn, Daewoo awarded KBR, the contract to provide topsides engineering, procurement and interface design services for the FPSO.

Pazflor uses a purpose-built FPSO with a topside weight of 35,494t. It is designed with a processing capacity of 200,000bpd of oil, 150mmcf/d of gas, and a storage capacity of about 1.9 million barrels of crude.

DSME constructed the vessel at its fabrication yard in South Korea. Facilities planned for a 20-year design life, and quarters are provided for 220 operation and maintenance personnel.

Total awarded a $1.1bn contract for subsea work to a consortium led by Technip with Acergy. Technip was responsible for engineering, procurement, fabrication and installation of more than 80km (50 miles) of production and water injection rigid flowlines, flexible risers and integrated production bundle risers, plus engineering, procurement and fabrication of 60km (37 miles) of umbilicals.

Installation took place in 2010 using Technip’s Deep Blue and Deep Pioneer.

Acergy was responsible for engineering, procurement, fabrication, and installation of 55km (34 miles) of water injection, gas injection, and gas export lines, umbilicals, and 20 rigid jumpers, plus installation of all manifolds, three subsea separation units with umbilicals and FPSO mooring lines.
