OLGA Flow Assurance

During this five-day course, you will learn how OLGA dynamic multiphase flow simulator is used to understand and solve typical flow assurance challenges.

This interactive and practical course includes step-by-step instructions to build and run simple transient simulation models. Key operational procedures are covered, like shutdown, start-up and pigging. Best practices and workflows are also presented for liquid and hydrate management, slugging recognition and mitigation, and fluid handling in OLGA.

The last two days are focused on advanced OLGA workflows to model separators, controllers, and how to model thermal interactions between pipes and surroundings.

All the main features of the OLGA GUI are covered, allowing you to easily build, edit and run models, create parametric studies, and view the results.
