Overview
Offshore pipelines and subsea systems connect wells, platforms, floating facilities and onshore terminals, and they are essential to the production of oil and gas from offshore fields. They must withstand high external pressure, seabed movement, currents, corrosion and third-party damage, while often operating for decades in locations that are difficult and expensive to reach. Failures can cause major production losses, environmental pollution and complex repair operations. Understanding how subsea systems are designed, installed, operated and maintained is therefore vital for engineers and managers working in offshore developments.
This course provides a practical overview of offshore pipelines and subsea production systems. Participants learn subsea field architecture, including wells, trees, manifolds, jumpers, flowlines, risers and umbilicals, and the factors that drive concept selection. The course covers pipeline design for pressure, stability, free spans and expansion, material and coating selection, and cathodic protection. It also explains installation methods such as S-lay, J-lay and reel-lay, trenching and burial, pre-commissioning, flow assurance challenges including hydrates and wax, subsea control systems, inspection with ROVs and intelligent pigs, integrity management, and subsea intervention and repair techniques.
Objectives
- Describe subsea field architecture and its main components
- Explain the key design factors for offshore pipelines and risers
- Select materials, coatings and cathodic protection for subsea service
- Compare pipeline installation, trenching and burial methods
- Identify flow assurance challenges and their mitigation in subsea systems
- Understand subsea control systems, umbilicals and production monitoring
- Apply inspection, integrity management and repair methods offshore
Who should attend
Pipeline, subsea and offshore engineers, project and integrity engineers, operations staff and managers involved in offshore field developments.
Training methodology
The course combines explanation of subsea technology with field layouts, design examples, installation videos and inspection reports from real offshore projects. Participants review subsea field concepts, carry out simple wall thickness and on-bottom stability checks, compare installation methods and evaluate flow assurance risks for given fluids and conditions. ROV and intelligent pig inspection results are interpreted to identify integrity threats. Case studies of pipeline failures and subsea repairs are analysed in groups. Each day ends with a short quiz and discussion of subsea challenges in participants' own projects and operations.
