Subsea Pipeline Risk-based Integrity Assessment

The first objective of this internship is testing and validation of recently customised RISKWISE software for subsea pipeline application using a case study. Second objective is to develop a user manual for the software for future reference. Testing and validation of the software would help provide reliability and confidence in the tool usage that will help in decision making regarding optimal inspection and maintenance planning for risk mitigation. Also, this study assesses the overall risk to pipeline operation based on observed damage mechanisms and recommends mitigating actions to be carried out to minimise risk over life cycle. The proposed research and development would aid in pipeline risk mitigation through optimal inspection and maintenance planning. Probabilistic models for damage mechanisms and consequences reduces data uncertainty and hence, operational risk to pipeline life. Furthermore, the study would identify limitations of the tool and potential areas for improvement. Having such a tool will be a benefit for offshore oil and gas operators.

This research project was undertaken and completed with a grant from and the financial assistance of Petroleum Research Newfoundland & Labrador.
