Inspection and Maintenance of Subsea Pipelines and Offshore

Introduction

This intensive 5-day foundation level course covers the principal aspects of design, construction, and operations of offshore pipeline systems. The course focuses on pipeline mechanical, strength, and stability design, and construction. Special challenges, such as shoreline crossings, foreign pipeline crossings, repair methods, flow assurance, corrosion control, and cathodic protection are an integral part of this course. Participants will acquire the essential knowledge and skills to design, construct, and operate pipelines. Design problems and team projects are part of this course. This comprehensive course on Subsea Inspection, Maintenance, and Repairs (IMR) provides participants with the knowledge and skills required to ensure the integrity and operational reliability of subsea systems. The course explores the criticality of subsea equipment, the complexities of corrosion management, and strategies to assess and mitigate risks effectively. Attendees will learn to identify and address common subsea anomalies and execute repair and maintenance strategies, guided by real-world examples and case studies.

Objectives

By the end of this training course, delegates will learn to:

• Apply mechanical, strength, and physical principles to pipeline design, material selection, construction, and operation
• Describe the key construction methods
• Define the importance of environmental conditions, construction methods, and pipeline system hydraulics in design, installation, and operations of offshore pipeline systems
• Identify special design and construction challenges of offshore pipeline systems
• Incorporate construction methods into the design of a pipeline system
• Identify the principal interfaces of pipeline facilities, such as platforms, floating production systems, subsea wellheads, and SPMs on design, construction, and operations of offshore pipeline systems
• Develop a thorough understanding of subsea systems’ critical components, operational challenges, and failure modes.
• Gain proficiency in applying risk-based inspection methodologies and fitness-for-service assessments to ensure asset reliability.
• Learn advanced techniques for anomaly detection, logging, and evaluation specific to pipelines and subsea structures.
• Master the planning and execution of subsea maintenance and repair strategies, including innovative technologies and cost-effective solutions.
• Analyze real-world case studies to understand practical applications, challenges, and lessons learned in subsea IMR.
• Identify offshore safety and environmental practices and their effect on design, construction, and operations

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
