Problem Statement  

IOC challenged to accelerate project first oil and reduce overall project CAPEX. Unclear if mothballed 500t platform deck and 300t jacket could be used instead of a new asset.

Aims

  • Allow the reuse of a mothballed asset to avoid costly procurement and increased schedule.

Method

  • Performed structural analysis and asset inspection.
  • Compared asset health against company spec. Created mitigation plan

Impact

  • Mothballed asset recommended fit for proposed use. Customer was able to purchase asset
  • Reduced cycle time to procure, install and commission jacket/ platform deck by 60%
  • Cost improvement estimated at 65% versus new structure
  • Environmental advantages gained from re-using existing infrastructure
