The purpose of this paper is to present an overview of the fifth module of Búzios Field Development, its features, and main achievements. It combines innovative concepts and technologies aiming to deal with challenges faced during the execution of Búzios 1 to 4 Projects, producing since 2018.
A robust concept of Subsea, Umbilicals, Risers, and Flowlines (SURF) was implemented associated with an execution strategy designed to reduce the risk of unpreparedness. The strategy integrates critical path analysis, schedule monitoring, and controlling mechanisms to mitigate risks of lack of readiness, streamlining well connections for FPSO (Floating Production Storage and Offloading) ramp-up. Besides that, rigid jumper metrology was taken out of the critical path through the application of indirect metrology between the PLET (Pipeline End Termination) Hub and the Xmas Tree.
The subsea scope was effectively divided into two primary components: an EPCI (Engineering Procurement Construction and Installation) contract for rigid pipe delivery and the utilization of Petrobras’ chartered PLSVs (Pipe Laying Support Vessel) for flexible installation. This approach optimized the installation schedule, ensuring efficient vessel allocation through integrated time, scope, and space monitoring.
The project introduced novel technologies through its FPSO, enhancing H2S removal from the gas export stream using an environmentally friendly solution—a selective membrane system. This innovation promises reduced solid bed consumption, leading to decreased waste disposal throughout the unit's lifecycle.
The methodologies presented help to enhance future offshore endeavors. It outlines a robust SURF concept and execution strategy, minimizing readiness risks and hastening FPSO ramp-up. The integration of critical path analysis, monitoring, and time-scope-space tools offers a distinct approach to concurrent operations. Innovative metrology and H2S removal advancements enhance efficiency and environmental sustainability, respectively.
The first oil of the Project was on May 31st, 2023, and the maximum capacity of the FPSO (150,000 bpd) was achieved just 146 days after that on October 24th, 2023, a Petrobras’ record. The achievement of these milestones is in line with the sound development plan of Búzios Field, which will reach a production of about 1.8 million bpd by 2028, when there will be eleven FPSOs in operation at the area.
