One of the most common practices during the operation of pipelines is “pigging”. Buildup of solids or liquids in flowlines can result in plugging, cracks, or flaws in the line, all of which could cause severe damage to the line. Pigging operations may be designed with objectives that include cleaning, inspecting of flowlines, or other…

A common flow assurance study objective is calculating the time required to reach hydrate conditions during a shutdown (typically from steady state). This is often referred to as ‘Cooldown’. The ability for an operator to understand the amount of time that is available to safely complete various tasks during a shutdown, or how close to…

The discussion starts with the question of why OLGA performs nearly the same on two different CPUs (an Intel Core i7 processer running at 3.4 GHz and Intel Core i5 processor also running at 3.4 GHz). This result is surprising…
