LNG FPSO mechanical equipment

  • Pressure vessels, Heat Exchangers, Pumps, Compressors are designed according to same requirements and specifications as on standard FPSOs; e.g ASME VIII, TEMA, API 674, API 617.
  • Most of the equipment will see the same operation conditions as on a standard FPSO.
  • LNG FPSO equipment novelties:
  • Braced Aluminium Heat Exchangers

: Proven on large LNG carriers

: Larger but within vendor experience range.

: Not operation sensitive to motion or liquid distribution

: Enclosed BAHX – no new material exposed to the marine environment

: Long experience for much more complex versions onshore

: Design according to ALPEMA standard

  • Cryogenic Expanders

: Not new to the marine environment

: Proven on the large LNG carriers

: Well within proven design capacity

  • Boil Off Gas Compressors

: Not new to the marine environment and LNG-tankers
