Installation calculations for subsea pipelines

About the course

Anyone involved in the installation analysis of rigid pipelines and modules will benefit from this course’s detailed explanation of installation calculations. This course will give you the opportunity to practice hand calculations with tutor support.

Assessing a selection of wire sizing for pull-in of pipelines and lowering of modules, this hands-on experience is the perfect platform to boost understanding of industry standards and codes. Giving you the confidence to independently assess and verify calculations, the tutor will guide you through a variety of worked examples and exercises, explaining how they are applied to real life scenarios.
