The objective of this paper is to present the main features and challenges of a major project at Petrobras, currently at the design stage, which consists of the revitalization of a large offshore oil field. This includes the installation of a new Floating, Production, Storage and Offloading (FPSO) vessel that will replace 4 existing oil platforms. To achieve this, it will be necessary to develop a new Subsea Production System, through the reorganization of existing subsea equipment and pipeline and the installation of new ones.
The major issues and challenges about this project are described: a) the complexity of the reservoir, as it combines both post-salt and pre-salt oil; b) the largest number of wells and the largest length of pipelines in a Petrobras project in history, which includes both existing and new wells and pipelines; c) the challenge during the removal of existing pipelines, due to the need to avoid coral reefs; d) the need to install several new manifolds, considering the long manifold tiebacks; e) the largest subsea pumping systems already installed by the company, which demands a high amount of electrical power from the FPSO; f) the large amount of risers, which requires a new design for the Riser Balcony of the FPSO.
