Course overview

Subsea pipelines have made a tremendous impact as a safe and effective hydrocarbons transport system. To date there have been substantive examples of global subsea pipeline projects where the boundaries of materials requirements, construction and installation techniques, inspection and maintenance programmes have all been established and improved upon over the decades.  Similarly, breaching deeper and deeper water depths, has seen even further improvements and technical innovation in these and other key areas.

This course has been specifically developed to fulfil industry’s ongoing need for skilled and competent pipeline engineering individuals.

The course will provide a comprehensive insight into the methodologies employed to execute subsea pipelines mechanical engineering design, together with requirements for pipeline routing, permits and authorisations, materials selection, pipelines construction and installation, offshore and vessel requirements, pipeline protection systems, pre-commissioning and commissioning practices, pipeline integrity management practices. In addition, delegates will also gain an appreciation of the support tasks and activities required for subsea pipelines design such as compilation of data sheets, drawings, materials take-off documentation, philosophies and specifications.

Pipeline related case studies and workshops will also be conducted to allow delegates an opportunity to test their pipelines knowledge and practical working examples of pipelines design will be presented.

The course is designed for

  • Subsea pipeline engineers
  • Construction & installation engineers / managers
  • Materials and Corrosion Engineers
  • Integrity engineers
  • Facilities engineers
  • Operations engineers and managers
  • Project Managers
  • Graduate engineers
