Mastering Corrosion Management Through Practical Exercises

Embark on a comprehensive exploration of our course content, culminating in a pivotal hands-on exercise tailored for delegates. This exercise offers an opportunity for participants to apply acquired skills and knowledge in the critical assessment of a corrosion defect within a multi-phase pipeline system. Beyond being a mere assessment, this exercise serves as a strategic platform for delegates to refine their problem-solving proficiencies and concretise the practical implications of the course material. Opting for our programme signifies a commitment to not just theoretical understanding but active engagement in exercises designed to prepare delegates for the intricate challenges of real-world corrosion management.

Module Highlights

Day 1 - Exploration of Corrosion Management - Types, Control Measures, and Fitness-for-Service Assessment

Participants will immerse themselves in the intricacies of corrosion types, defect categorisation, and the effectiveness of corrosion control measures. The day also includes in-depth insights into corrosion monitoring and inspection techniques through practical case studies. The subsequent sessions focus on fitness-for-service assessment, addressing the classification of corrosion defects, corrosion rate modelling, defect interaction, and different assessment approaches. Attendees will gain knowledge about the limitations and applicability of assessments, the determination of fitness-for-service, and ongoing management strategies.

Day 2 – Mastery of Industry Standards - ASME B31G and DNVGL-RP-F101 Approaches

Participants will focus on mastering industry standards, with a detailed exploration of the ASME B31G approach. This includes an examination of the differences between the original and modified approach, understanding various levels of assessment, and delving into defect acceptance criteria and measurement uncertainty. Practical learning is reinforced with a defect assessment worked example, specifically addressing challenges posed by long defects and deep pits. The day progresses to an in-depth study of DNVGL-RP-F101, differentiating between Part A and Part B approaches, examining levels of assessment, and understanding defect acceptance criteria and measurement uncertainty. Participants will engage in another defect assessment worked example, this time dealing with longitudinal and circumferential defects and exploring the validity limits, supplemented by the application of the Kastner approach.

Day 3 –Advanced Pipeline Integrity Assessment: FEA and ECA Techniques

This day starts with guidelines on transitioning to a Finite Element Analysis (FEA)-based approach, including inspection data requirements and the application of API579 for corrosion defect modelling. The course then addresses Engineering Critical Assessment (ECA), discussing defects requiring ECA, applicable codes and standards (DNVGL-RP-F108 and BS7910), and includes a worked example. An exercise is included where participants assess the acceptability of a corrosion defect in a pipeline system using recent Inline Inspection (ILI) data.
