Subsea Pipelines

About the Course

The Subsea Pipelines course is an immersive training programme designed to provide subsea engineers with a foundational understanding of pipeline systems used in the offshore oil and gas industry. This course comprehensively covers the technical and practical aspects of subsea pipelines from conception through to decommissioning, offering delegates a broad perspective on the complexities involved in their design, installation, and maintenance.

At the heart of the course is the study of pipeline systems, focusing on the intricacies of field layouts and the use of pipelines and cables in subsea settings. Delegates will explore various subsea equipment and understand how platforms and floating production systems are integrated with pipeline infrastructure. The content further delves into riser configurations, providing insight into the engineering challenges and solutions associated with connecting subsea systems to surface facilities.

Route selection and the accompanying surveys are critical components of the course. Delegates will learn about the different types of surveys needed for effective route selection, including geophysical and hydrographic surveys, and the techniques employed to gather necessary data. This knowledge is crucial for ensuring the safe and efficient routing of pipelines along the seabed.

Another significant aspect of the course covers the manufacturing processes of pipes, including both rigid steel pipes and flexible pipes, and the selection of materials based on strength and corrosion resistance. The course details the differences between clad and lined pipelines, helping delegates make informed decisions regarding material and design to enhance the durability and functionality of subsea pipeline systems.

Pipeline design principles form a core module of the training, where delegates are taught to calculate pressures, size diameters, and determine wall thicknesses for various conditions such as bursting, hydrostatic collapse, and local buckling. Understanding global buckling, external coatings, and external corrosion and protection through methods like cathodic protection are also included to give a thorough grounding in the design and safeguarding of subsea pipelines.
Installation methods are a key focus, with detailed discussions on S-lay, J-lay, and Reel-lay techniques, alongside less conventional methods such as bundles and towed installations. The course also addresses the construction and pre-commissioning stages of pipeline projects, including welding, non-destructive testing (NDT), trenching, and burial.

Operationally, the course covers pipeline integrity and maintenance, including flow assurance, operational controls, and the use of additives and pigging to maintain pipeline efficiency and safety. Delegates will engage with real-world case studies to identify best practices and learn from past incidents, providing a practical perspective on managing pipeline systems.

In addition to technical skills, the course emphasises the importance of pipeline integrity management systems (PIMS) and risk-based inspection plans. It concludes with an exploration of pipeline decommissioning and the regulatory frameworks that govern subsea operations, ensuring delegates are well-versed in the lifecycle management of subsea pipelines.

Overall, this course is designed not just to impart technical knowledge, but to cultivate a comprehensive understanding of subsea pipeline engineering, preparing delegates to contribute effectively to the industry and advance their careers in subsea engineering. Through a blend of theoretical learning and practical application, the Subsea Pipelines course is an essential stepping stone for any subsea engineer looking to enhance their expertise in this critical field.
