RISER DESIGN

  • Detailed design and analysis of Riser systems including shallow and deep water configurations.
  • Review and re-analyse technical report of third party.
  • Manage and provide technical support to naval architects/interns.
  • Research and development of new mooring design systems.
    • Semi-sub and drillship drilling risers (shallow and deep water)
    • Drilling risers on jack-up rigs
    • Platform drilling risers
    • Specialist high-pressure risers
    • Production risers
    • Platform conductors
    • Pipeline risers
    • Flexible risers
    • Steel catenary risers
    • Umbilicals
    • Subsea cables

TYPES OF RISER ANALYSIS

  • Strength and stability (stress, “Baur & Stahl” buckling assessment, overbending)
  • Vortex induced vibration (modal analysis)
  • Wave induced fatigue
  • Tension optimisation
  • Thermal expansion
  • Installation/deployment
  • WSD and LRFD (limit state) methods
  • API, DNV, and IP codes/standards/guidelines
  • Elastic and plastic material models
