About the course

This course provides learners with an opportunity to improve their knowledge of offshore pipeline installation techniques. It also allows them to enhance their appreciation of the capabilities of the latest pipe-lay vessels and equipment and gain confidence in identifying the best technical solutions for the projects.

Explaining a variety of pipe-lay and pipeline protection methods for rigid and flexible risers, this course will develop learners’ ability and confidence to select the most suitable method for different scenarios. Associated activities including surveying, diving and also pre-commissioning are discussed in this course. This course also covers the construction process for risers, spools, stalk-ons, pipeline end manifolds (PLEMs) and terminations (PLETs) and alternative installation methods, such as mechanical connectors.
