Many of the key issues integral to CAPCIS' business manifest themselves in the subsea systems of oil and gas developments. It is here that the impact of production chemistry is most prominent; where the current condition of infrastructure is most uncertain, where the cost implications of material selection are highest, where the importance of inhibition to manage residual risk is most prominent and where the impact of intervention is most severe.

CAPCIS services pervade all aspects of subsea design and operations as outlined below:

• Understanding production chemistry and its impact on material performance in subsea operating environments throughout field life.
• Material selection and the management of residual risk through the development of effective inhibition and operational management strategies.
• Independent inhibitor performance assessment and inhibitor selection.
• Material endurance testing (fatigue testing) in aggressive environments, for example the testing of flexible risers and their component materials for deepwater applications at the boundaries of industry experience.
• Pipeline Commissioning Strategies.
• Corrosion Risk Assessment for existing infrastructure addressing the inherent uncertainty resulting from lack of operational, monitoring and inspection data.
• Inhibitor Optimisation during late field life and pipeline risk assessment to determine risk associated with extended life.

Our role is to provide operators with an assessment of the condition of subsea infrastructure and the impact of current operational strategies; the inherent uncertainty of the assessment and ways to improve confidence in its results; the residual risks associated with future operations and the effect of alternative mitigation strategies on asset integrity and remaining asset life.
