Fundamentals of Deepwater Riser Engineering

Introduction

This training course is an introduction to the world of deepwater subsea products. There are many components in the field architecture of offshore and subsea projects, varying from Xmas Trees, manifolds, controls systems, and risers with their variety from drilling to completion to production and injection risers.

This 5-Day training course will provide the basics of riser engineering by identifying the various riser types, their main components, the fundamental design methodologies used to identify the appropriate design for each project as well as running through the product life cycle and detailing the testing requirements for risers and their components and moving on to the main installation techniques and finally addressing the integrity management and life of field operation of deepwater risers.

This training course will highlight:

• Overview of offshore and subsea projects
• Fundamentals of offshore and subsea intervention
• Introduction to riser types
• Design requirements and selection of risers
• Drilling and completion risers
• Rigid risers (top tension risers, steel catenary risers)
• Hybrid flexible risers
• Risers integrity management
• Risers IRM (Inspection, Repair, and Maintenance) requirements

Objectives

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

• Develop a global understanding of offshore and subsea architecture considerations
• Understand the environmental parameters affecting the design of Deepwater risers
• Determine the different types of risers and their equivalent applications from drilling, completion and production/injection
• Learn about the installation process for the various types of Deepwater risers
• Determine the integrity requirements for Deepwater riser systems as well as understand the aspects covered in inspection and maintenance programs offshore
• Address the technical aspects of Deepwater risers on a day to day basis and apply the learning from the course in a real-life setup

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.
