BOULOGNE-BILLANCOURT, France – Vallourec is to provide a range of connection devices for Total’s CLOV deepwater oil and gas development offshore Angola.
CLOV comprises the oil and gas fields Cravo, Lirio, Orquidea, and Violeta in block 17, in water depths ranging from 1,100-1,400 m (3,609-4,593 ft). Production is due to start in 2Q 2014.
Vallourec will equip the 34 subsea wells with around 15,000 tons of OCTG products featuring VAM premium connections. Two of the rigs drilling CLOV’s development wells are also using Vallourec drillstrings and connections.
The subsea wells will be tied back to the new CLOV FPSO, which arrived at the Paenal Yard in Porto Amboim, Angola, last week.
To secure transportation of hydrocarbons to the FPSO, Vallourec has delivered 28,500 tons of coated seamless line pipe and bends to installation contractor Subsea 7. The company supplied an additional 2,400 tons of seamless pipe for construction of the riser towers.
Vallourec is also supplying around 150 km (93 mi) of anticorrosion coating on the pipes and roughly 700 hot induction bends. The production flowlines, which include a pipe-in-pipe solution, will be assembled in Angola.
Serimax, Vallourec’s welding specialist, operated its Saturnax 09 welding equipment during seven months onboard Subsea 7’s pipelay vessel Seven Borealis. It delivered around 5,500 welds on pipes, including corrosion- and fatigue-sensitive sections.
