- Course Overview
- Comprehensive exploration of subsea asset integrity management focusing on the unique environmental challenges of deepwater and ultra-deepwater production environments.
- Detailed analysis of the Risk-Based Inspection (RBI) methodology as defined by international standards like API 580 and API 581, specifically adapted for subsea hardware.
- Evaluation of subsea degradation mechanisms including internal and external corrosion, erosion, and fatigue in dynamic subsea components such as risers and umbilicals.
- Examination of the Probability of Failure (PoF) calculation processes, incorporating historical data, operating conditions, and material properties of subsea structures.
- In-depth study of Consequence of Failure (CoF) assessments, weighing the environmental, safety, and economic impacts of subsea equipment leaks or structural collapses.
- Introduction to Subsea, Umbilicals, Risers, and Flowlines (SURF) inspection strategies, focusing on how to prioritize maintenance for high-risk system nodes.
- Strategies for moving from prescriptive, time-based inspection intervals to optimized, risk-driven schedules that maximize vessel and ROV utilization.
- Case studies on life extension projects for aging subsea fields, demonstrating how RBI can safely justify operations beyond the original design life.
- Understanding the data integration pipeline, from raw sensor outputs and ROV footage to actionable integrity reports within an Asset Integrity Management (AIM) system.
- Focus on regulatory compliance for major offshore jurisdictions, ensuring that RBI plans meet the rigorous safety requirements of global energy authorities.
- Assessment of cathodic protection (CP) monitoring and its role in the long-term integrity of subsea manifolds, trees, and wellheads.
- Review of emergency response planning linked to RBI outcomes, ensuring that high-risk assets have robust contingency measures in place.
- Requirements / Prerequisites
- A foundational understanding of offshore oil and gas production systems and general subsea field architecture.
- Basic knowledge of mechanical engineering principles, particularly regarding pressure vessels, piping, and materials science.
- Familiarity with corrosion science and common metallic degradation processes in marine environments is highly recommended.
- Prior exposure to Asset Integrity Management (AIM) or general maintenance planning concepts in an industrial setting.
- An undergraduate degree in Engineering (Mechanical, Petroleum, or Marine) or a related technical discipline is preferred but not mandatory.
- Working knowledge of Microsoft Excel for basic data manipulation and risk matrix plotting exercises during the course.
- Skills Covered / Tools Used
