Flow Assurance and Process Engineering

The following are among the flow assurance capabilities:

  • Fluid property calculations using PVTSIM
  • Steady State analysis using PIPESIM (including pipeline sizing optimisation, pressure and temperature profiles, turndown, erosion velocity ratio, slugging etc.)
  • Hydrate and Wax management strategy
  • Insulation selection (U-value optimisation)
  • Liquid management and slug catcher optimisation
  • Transient analysis using OLGA (including Pipeline cool-down, restarts, ramp-up, packing, blowdown analysis)
  • HIPPS response time evaluation
  • Pigging simulation and optimisation


The following are among the subsea process capabilities:

  • Subsea Process drawing development e.g. P&ID, PFD, C&E diagrams
  • Design pressure & temperature philosophy
  • Choke valve sizing
  • Start-up and Shutdown operating guidelines
  • Hydrate remediation strategy
  • HIPPS system operational test procedures
  • HAZID & HAZOP, LOPA participation
  • Equipment duty specification/datasheet
  • Technical evaluation of vendor proposals
