Lloyd’s Register has granted Petrobras Approval in Principle (AiP) for the conceptual design of the proposed REVIT I TUPI floating production, storage and offloading unit. Announced on November 5, the approval supports plans to revitalise the Tupi field offshore Brazil.

Based on the P-68 Design

The proposed FPSO draws on the design of P-68, which operates in Brazil’s Santos Basin. Petrobras plans targeted modifications to processes and systems to meet the requirements of the Tupi development.

Using an established design allows the operator to build on operating experience while seeking to reduce engineering complexity, development risks and project delivery times.

Scope of the LR Review

LR’s assessment of the preliminary documentation identified no conceptual issues against applicable industry reference requirements. It concluded that the concept could be developed into a safe and viable design through subsequent engineering stages.

The review covered process flow diagrams, piping and instrumentation diagrams, equipment specifications and supporting technical studies.

LR also examined Petrobras’ methodology for managing design changes, including how modifications to the original P-68 configuration would be identified, assessed and implemented throughout the project lifecycle.

Further Engineering Ahead

The AiP represents an early milestone for REVIT I TUPI. Further engineering will be needed to develop the concept and refine the technical solutions for the proposed unit.
