Brazilian state oil company Petroleos Brasileiros SA (Petrobras) has awarded Coflexip Stena Offshore (CSO), Paris, and Premier March� Brazilian entity Flexibr�the Roncador contract to design and install 566 km of flexible risers, flowlines and umbilicals, to tie-back 21 satellite subsea wells to the P-36 platform.
Roncador field is in the Campos basin, 125 km off the Rio de Janeiro coast in Brazil, at 4,600-6,200 ft water depth, the deepest development in the world to date.
This contract includes work on 374 km of flexible risers and flowlines as well as nearly 192 km of umbilicals to connect 21 subsea wells and a gas lift manifold to the P-36 semisubmersible platform located in 4,500 ft of water.
Production began last May. Five wells were producing to date 21 are planned by 2003. With its 180,000 b/d production capacity, P-36 is the largest production platform in the world.
The conttract is expected to be completed 30 months, with installation in three different campaigns concluding at the end of the first quarter of 2003.
Flexible lines will be manufactured by both CSO�s plants in Vit�ria, Brazil, and Le Trait, France. CSO units will engineer, manufacture and supply the 111 km of flexible risers and flowlines for the first installation phase in the second and third quarters of 2001. Timetables for the other phases will be set later.
After completion of the contract, Roncador field will be operated through 26 wells. Coflexip Stena Offshore installed the production lines on two of the other five wells on Roncador in April and June 2000, when world depth records were set for flexible pipe in 6,036 ft and 6,178 ft respectively.
