Decommissioning

With over 10 years experience, Jee is an expert in the decommissioning of oil and gas assets. Complemented by our integrity management and lifetime extension capabilities and expertise, we provide a suite of decommissioning services to support our clients through all stages of a decommissioning project, from initial feasibility studies and cost estimations, through detailed engineering and offshore activities, to project completion and close-out. This includes:

  • Identification of optimum decommissioning strategy through technical assessments and cost modelling;
  • Decommissioning cost estimation and independent review of ABEX estimates
  • Assessment of decommissioning methods for structures, pipelines and risers through onshore studies. This includes performance of both screening level and full comparative assessments;
  • Development and writing of decommissioning programmes and procedures;
  • Determination of cleaning approaches and management / technical assurance of offshore activities;
  • Review of structural and pipeline inspection requirements at various stages in the decommissioning process, accounting for changes in the risk profile;
  • Project management and support of decommissioning programme execution and close-out, including liaison with the regulatory bodies;
  • Definition, management and assessment of overtrawling surveys following completion of decommissioning works;
  • Management of disused pipelines following cessation of production and of pipelines decommissioned in-situ.

We have practical experience in decommissioning project engineering, including well abandonment, pipeline decommissioning, topsides removal and jacket removal (or derogation). From this experience, we have developed an in-depth understanding of:

  • The issues involved;
  • Equipment available for decommissioning at present and emerging technologies;
  • The associated vessel rates and typical timeframes for the decommissioning of certain components;
  • Scheduling and sequencing efficiencies to be gained in the decommissioning of hubs;
  • The recycling / disposal routes and associated costs.
