Pipeline reel-lay

About the course

Detailing the engineering behind reel-lay installation, this is an advanced course that demystifies this complex field. Ideal for reeling companies and anyone involved in the design and installation of pipelines, this course explains the fundamentals of reel-lay.

The tutor will explain key design aspects such as the implications of cumulative plastic strain, ovalisation and weld defects using worked examples and exercises. You will receive guidance on codes and patents and review lessons learned from past successes and failures, developing your skills for installation projects.

Learning outcomes

  • Describe some of the latest developments, including SENT (single-edge notch tensile) test assessments, the use of lined pipe and partially pressurised lines
  • Consider key design aspects such as the implications of cumulative plastic strain, ovalisation and weld defects
  • Assess a vessel’s capability in reel-laying
  • Apply lessons learned from case studies to projects
