Production & Export

Production & Export

2H’s riser engineering expertise and experience covers the full range of riser configurations used in the production and export of offshore hydrocarbons. Our core capability is our strength in analysis and engineering of dynamic structures coupled with a wealth of experience in mechanical and material engineering.

We have been at the forefront of riser technology for over 20 years, identifying and developing configurations to meet evolving industry demands, particularly due to increasing design pressures and water depths. The breadth of our experience allows us to quickly identify and develop riser systems to suit often complex and inter-related project requirements. We have had key responsibility on many cutting edge projects working with a wide range of operators and installation contractors.

Our expertise in production system risers includes most combinations of vessel type, geographical location and riser that have been implemented to date:

  • Steel catenary risers (SCRs) – simple, lazy wave
  • Top tensioned risers (TTRs) – single, multistring, production and drilling
  • Freestanding/hybrid risers – single pipe, pipe-in-pipe and bundle (FSHR, SLOR, COR)
  • Flexible risers (bonded, unbonded)
  • Subsea umbilicals
  • Riser base and subsea well jumpers
  • Composite risers
  • Semi-submersible, TLP, Spar, FPSO, FDPSO, and jack-up vessels

Our project involvement begins with riser concept evaluation, feasibility assessment and selection and runs through FEED, detailed engineering, procurement and installation support and management to in-service integrity management.

Being independent of any manufacturing or installation company, we can engineer production system risers as the main contractor, sub-contractor, part of an integrated project team or in the capacity of a certification and verification agent (CVA).
