Scope

rhi was engaged by the client to deliver a decommissioning cost estimate as part of the client's re-development and PS-3 Life Extension Pre-FEED study. The decommissioning estimating scope was part of a feasibility study to relocate the MM new processing complex to a greenfield location away from the existing Production Station (PS), replace all the existing flowlines and facilitate smooth switchover from the old PS to the new PS at the greenfield location.

Services
  • Develop decommissioning estimates for PS-3 platforms, interconnecting bridges and pipeline infrastructure.
  • Produce Basis of Estimate document and cost estimate report including associated benchmarking charts.
  • Produce overall decommissioning schedule.
  • Prepare Class 3 decommissioning cost estimates for alternative decommissioning strategies as part of Comparative Analysis studies.
  • Provide Basis of Estimate document detailing assumptions underpinning the rhiDEMS cost estimates.
  • Prepare and present suitable benchmarks for topside and jacket removal costs.
  • Produce associated removal schedule.
​Value-added by rhi
  • Access to industry leading in-house decommissioning cost estimating and scenario modelling tool rhiDEMS.
  • 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.
  • Access to Wood’s global market intelligence and regional capabilities.
  • Ability to work with the clients team and respond to new challenges as they evolved based on a joint analysis of model outputs and identification of the key strategic levers.
