RIO DE JANEIRO –The 2014-2018 Petrobras Business Plan foresees the allocation of $10 billion in the oil and gas sector, including projects related to subsea pipelines for gas transportation from the presalt area, such as Rota 3. Tenaris has been awarded the supply in this project, and will provide, starting in 1H 2015, 373 km (232 mi) of welded pipes. The gas pipeline will have the capacity to transport 21 MMcm/d (742 MMcf/d).
The scope of the project foresees 22-in. pipes for the onshore section between Maricá and Itaboraí, 24-in. pipes in the shallow offshore stretch, and 20-in. pipes in the stretch located in water depths from 1,500 to 2,300 m (4,920 to 7,544 ft). The pipes will be produced by Tenaris inBrazil. Tenaris says the new U-O forming presses produce pipes of greater thicknesses and higher steel grades, capable of withstanding the hostile environments in the exploration of ultra-deep waters, which include high pressures.
Expected to be in operation by 2016-2017, Rota 3 will link the areas of Franco (SP) and Maricá (RJ), assuring the increase of oil production from the presalt layer, and guaranteeing the transportation of natural gas extracted from the presalt to Comperj (RJ Petrochemical Complex) in Itaboraí.
