Day 1 - Reel-lay Process and Market Overview

Day one introduces the reel-lay process, covering system configuration, spooling, installation, and lay down. It also explores the history and development of reeling, including current market trends, reel-lay ships, and companies around the world. The day concludes with case studies on both failures and successes in reel-lay projects.

Day 2 – Technical Aspects and Forces

On the second day, participants delve deeper into the technical aspects of reel-lay engineering. This includes a thorough analysis of strain concentration, exploring the critical role of material qualification in the process. The day also focuses on identifying and addressing weld defects, understanding ovalisation, and comprehensively examining the reeling forces. The session covers the nuances of forces required for reeling-on pipelines, stresses encountered once reeled-on, and the complexities of straightening methods.

Day 3 – Advanced Topics in Ovalisation, Welding, and ECA

The third day focuses on ovalisation and its recovery, delving into the calculation of collapse pressure and addressing combined loading challenges. Participants will also explore welding methods, procedures, and inspection techniques, which are crucial for ensuring pipeline integrity. The day proceeds with an in-depth look at Engineering Critical Assessment (ECA), discussing applicable codes, standards, and methodologies from DNVGL and BSI. Additional case studies are presented, offering insights into optimised reeled pipe design, cost-effective reeling strategies, and innovative approaches for deep water pipeline and riser installation.
