Petrobras has christened, at the Brasfels shipyard, in Angra dos Reis (RJ), the P-57 vessel platform, which will operate in the Jubarte field, in the Espírito Santo portion of the Campos Basin, 80 km off the Espírito Santo coast. This unit opens the way for a new generation of platforms, designed and built based on an engineering concept that focuses on streamlining projects and standardizing equipment. This is a model that will be a reference for future Petrobras platforms, such as the P-58 and P-62, and for units that will operate in the Santos Basin pre-salt cluster.
The P-57's production system is equipped with a new technology to collect 4D seismic data, permanently installed on the seabed. This solution will afford greater flexibility in obtaining seismic data while improving reservoir interpretation quality, and, thus, optimize production. The unit will also adopt an innovative method to lift the oil that is in the reservoir up to the platform. The approach consists of a centrifugal subsea submersible pump (BCSS) installed in a special compartment on the seabed, separated from the producing wells. This design will allow for cost reductions in the event of equipment repair.
The engineering, procurement, and construction contract for the P-57 was signed in February 2008 with Single Buoy Moorings Inc. (SBM). The platform's hull was converted from the Island Accord oil tanker at the Keppel Shipyard, in Singapore, between October 2008 and March 2010. Simultaneously, the oil and gas processing modules were built in Brazil, at the UTC Engenharia construction site, in Niterói (RJ), and at the Brasfels shipyard, in Angra dos Reis (RJ). The hull arrived at the Brasfels shipyard last April, when module installation was completed, all systems were interconnected, and the unit's final tests ran.
Simplification and efficiency
The knowledge gained from building the P-57 will serve as a model both for the design of the P-58, P-62, and P-63 platforms, and for the "replicant FPSOs" intended for use in the Santos Basin pre-salt area (state of São Paulo). The new unit's design was simplified and its equipment standardized pursuant to the highest operating safety standards. This strategy ensured greater efficiency both in project management and in the progress of the procurement, construction, assembly and testing stages. The result was the strict compliance with contractual terms, the maintenance of the initial planned cost, and the assurance of the quality demanded under the contract. Additionally, the new strategy resulted in a lighter, easier-to-maintain platform, a significant gain, therefore, from the economic, managerial, and technical standpoints.
