Lifetime Extension of Rigid Pipelines and Flexibles

Comprehensive Overview of Pipeline Lifetime Extension

This course delivers an extensive insight into the Lifetime Extension (LTE) process for rigid pipelines and flexibles, commencing with an introduction to LTE, encompassing failure modes, inspection methodologies, and operational integrity management. Progressing to discussions on internal and external inspections, design reviews, and risk assessment methods, the programme culminates with a comprehensive analysis of remnant life assessments, focusing on corrosion, fatigue, and degradation mechanisms. It concludes with strategies for late-life integrity management, imparting essential knowledge and skills for effective pipeline management.

Mastering Pipeline LTE: Jee’s Industry-Pioneering Course

As the conveners of the working group for ISO TS 12747, Jee stands at the forefront of defining methodologies for Lifetime Extension (LTE) of rigid pipelines. This positions our course as an exceptional opportunity for delegates seeking the latest, industry-leading expertise. By choosing our programme, delegates gain unparalleled insights directly from the architects of key industry standards. This not only enriches their knowledge with cutting-edge practices but also provides them with a competitive edge in their professional landscape, ensuring they stay ahead in the ever-evolving world of pipeline integrity.

Module Highlights

Day 1 - Foundations of LTE for Rigid Pipelines and Flexibles

Day one of our course offers a foundational understanding of the Lifetime Extension (LTE) process for rigid pipelines and flexibles. Delegates are introduced to the critical need for LTE, relevant codes and standards, and the challenges associated with data management. The day proceeds with an analysis of common failure modes in pipeline and riser threats, both onshore and offshore, coupled with industry guidance. Additionally, we explore flexible pipe threats, delving into failure modes, industry guidance, and inspection methods. The day concludes with insights into operational integrity management, encompassing Pipeline Integrity Management Systems (PIMS), flow assurance, leak detection, and monitoring and testing techniques.

Day 2 – In-Depth Inspection and Risk Assessment

The second day centres on internal and external inspection and assessments, guiding delegates through the array of available technologies, the tool selection process, and special considerations for flexibles and risers. The day also addresses external inspection and assessment, including inspection criteria, global techniques, and specific requirements for flexible risers. Further, delegates engage in a comprehensive design review, examining aspects such as wall thickness, stability, line pipe specifications, and safety systems. The day culminates with an in-depth look into risk assessment, exploring failure statistics, measuring consequences, and the risk assessment process itself.

Day 3 – Advanced Remnant Life Assessment and Integrity Management

Day three is dedicated to advanced topics in remnant life assessment and late-life integrity management. The focus is on assessing internal and external corrosion, with discussions on corrosion rate evidence, industry norms, and remnant life calculation. We also explore fatigue damage principles, operational and riser fatigue, and the role of Joint Industry Projects (JIPs) in addressing flexible degradation mechanisms. The day concludes with a comprehensive look at late-life integrity management, covering inspection regimes, Risk-Based Inspection (RBI), stakeholder management, obsolescence challenges, and decommissioning strategies.
