Project Timeline:



Oil and Gas

rhi was engaged by the client to provide decommissioning estimates for their two gas condensate fields, including production platforms and subsea infrastructure assets located in the Nam Con Son Basin.

  • Utilise rhiDEMS offshore facilities modelling tool to develop decommissioning estimates for Client’s production platform, subsea wells and associated subsea infrastructure.
  • Deliver 3rd Party cost estimate as verification of decommissioning liabilities in support of clients Vietnam ARO submission​
  • Develop decommissioning estimates for the production platform with 4-subsea tie-backs including export pipeline infrastructure.​
  • Produce variance analysis report with commentary and recommendations.​
  • Produce overall decommissioning schedule.​
Value-added by rhi
  • Access to rhi’s pool of experienced practitioners to prepare verifiable man-hour, cost and vessel estimates directly from established in-house tools.​
  • Ability to produce cost estimates for a variety of scenarios directly from the toolset without the need for time-consuming, detailed re-estimating. ​
  • Access to wider rhi knowledge base of global metrics and regional market rates.​
  • Access to Wood’s team technical experts and expertise to guide, develop, quantify and assess the range of feasible alternative removal strategies together with their impact on cost & schedule.​
  • Ability to work with the Client’s team and respond to new challenges as they evolved based on a joint analysis of model outputs and identification of the key strategic levers. ​
