Andrew (AAD) Rewheel Gas Compression Study*

Client: BP

  • Field (Type): Andrew (Oil & Associated Gas; Offshore UK)

  • Objectives:

    • The client wanted to investigate existing operational, reliability and control issues of the compression train and desired recommendations to resolve them

    • The client required support to develop a new compressor rewheel design to resolve reliability issues

    • The client required support to size new rebundled compressor to handle future integration of satellite fields arising from wider field developments and expansions

  • Challenge: The driver for the study was existing reliability issues of the compression train and the unit not being fit for purpose for planned tie-in of satellite fields 

  • Our Engagement*: We were engaged as Engineering Consultants because of our unique gas compression expertise and understanding of the client’s asset portfolio.

  • Approach: In-service performance analyses and benchmarking of gas compression train. Machinery and process modelling and simulation. Centrifugal compressor redesign and sizing.

  • Stake: Inability to get more value from the asset due to the compression train failing to accommodate additional hydrocarbons from planned tie-ins.

  • Results:

    • The efficiency of the compression train was demonstrated to have improved

    • The new design improved performance and integrity of the compression system

    • The process gas centrifugal compressors were successfully redesigned to handle tiebacks to Kinnoull, Arundel, LC and Mabel fields.

* NB: Some projects may have been performed by consultant in previous roles.
