Subsea Life Extension Asset & Decommissioning Course Preview

As an asset reaches its initial design age or decommissioning age, a life extension study (LES) can be conducted to assess its condition and fatigue. This provides a cost-efficient option for safely extending the life of existing assets. LES are flexible and adaptable to the needs of individual clients and assets, but must be considered in advance in terms of inspection planning and timeline. Life extension studies are a flexible, fit-for-purpose service. Projects are unique to each client and unit, and begin with regular exchanges between a client and technical experts to define the project scope and timeframe. The study primarily consists of an onboard inspection to assess the unit’s current status and a structural analysis to determine its capacity to operate beyond its design life.

Subsea decommissioning activities include vessel preparation for desired end-state (remove, trench, rock-dump), sea fastening and transportation. Infrastructure includes pipelines, umbilicals, subsea christmas trees, manifolds, subsea isolation valves and electrical cables. Prior to any removals, the facilities on the platform and pipelines used to recover and transport the hydrocarbons must be de-energised. Pipeline cleaning programmes are designed to ensure the hydrocarbon content and any deposits within the pipeline are dealt with, considering the future Decommissioning Programme.
