Most design and operating companies now acknowledge that the majority of problems are caused when plants and pipelines are started, shutdown or when flow and operational changes are made. Collectively, these operations can be termed ‘Dynamic’ to differentiate them from the less problematic steady operations.
Dynamic Simulation technology has the capability to accurately study all of these operations at design stage or when the system is operating, to identify any problems and thereby study remedial measures (such as surge suppression or design modifications).
So dynamic simulation is frequently incorporated into design stage work to identify any problems that could occur during normal start-up, shutdown and emergency situations. Or to establish if the proposed control system is stable and effective. Dynamic simulation is non-intrusive so can be used to study even the most severe emergency scenarios.
Simulation studies offer a cost-effective method of reducing risk, demonstrating system safety and optimising equipment specification and selection.
In operating systems, simulation provides the only effective way of investigating problems without interfering with the operation of the system and plant.
Statistically, high pressures cause more frequent problems on pipelines. But Start-up and shutdown can also cause low pressures (down to the vapour pressure of the fluid being transported) and this can also cause structural problems and can collapse some pipes.
Standards
Simulation is mentioned, recommended and stipulated by most pipeline codes of practice and oil industry standards. It is also stipulated in most design guides through the major Oil Companies, Consultants and Contractors.
