Module Highlights

Day 1 - Foundations of Subsea Systems

The course begins with a comprehensive introduction to subsea systems, exploring the motivations and primary components involved in subsea operations. It delves into the architecture and design of these systems, covering aspects such as host facilities, export routes, subsea flowlines, risers, and enhanced recovery techniques. The day also addresses flow assurance, chemical injection, subsea pigging, challenges related to water depth, and strategies for Inspection, Maintenance, and Repair (IMR), providing a robust foundation in subsea systems​.

Day 2 – Drilling Subsea Wells

Focusing on drilling subsea wells, day two introduces various drill rig types and their operations. It details the drilling sequence and the essential hardware used in these operations, including subsea wellhead systems, Blowout Preventers (BOP), and drilling risers. This session is crucial for understanding the technical complexities and logistical challenges involved in drilling operations beneath the sea, highlighting the practical aspects of subsea drilling.

Day 3 – Completion and Subsea Trees

Day three progresses into the completion phase of subsea wells. It covers critical processes like well logging, testing, and the sequence of completion, along with necessary hardware components such as tubing, down-hole safety valves, and chemical injection systems. The day also provides an in-depth look at subsea trees, examining different types like dual-bore vertical, horizontal, and mono-bore vertical trees, focusing on their selection, valve functions, instrumentation, and components that can be retrieved for maintenance or replacement.

Day 4 – Subsea Processing and IRM

The final day of the course covers subsea processing technologies, including multiphase flowmeters, pumps, compressors, and methods for separation and water reinjection. It also delves into the installation and commissioning processes for subsea systems, discussing installation issues, methods, and videos to aid understanding. Additionally, this day emphasizes subsea inspection and repair management (IRM), exploring subsea vulnerabilities, diving, Remotely Operated Vehicle (ROV) operations, Autonomous Underwater Vehicles (AUVs), and various techniques for inspection, repair, and integrity testing of subsea wells.
