Búzios is a large deepwater oil field located within the Cessão Onerosa region of the pre-salt Santos Basin in Brazil. The offshore field covers an area of 416km² and is situated approximately 200km off the coast of Rio de Janeiro at water depths ranging between 1,600m and 2,100m.
Mechartes conducted pulsation analysis for suction and discharge piping networks, considering operational scenarios with the pump and standby pumps working. Peak-to-peak pressure variations were assessed to predict liquid hammer conditions, adhering to Design Approach-2 API-674 3rd edition guidelines. Vibration and harmonic loads throughout the pipeline length were evaluated using PULS software.
Mechanical vibration analysis in Bentley AutoPIPE ensured that the pipeline’s natural frequencies did not coincide with pump frequencies. Harmonic loads identified by Bentley PULS were then simulated in AutoPIPE to assess stress and deflection. Based on these analyses, Mechartes recommended design modifications such as adjusting pulsation dampener volumes, orifice plates, and pipe supports to optimize pipeline performance and reliability.
Additionally, pipe stress analysis was performed on the connected piping network to determine suitable support types and locations.
