Hence PVTSIM is also necessarily to be purchased sinceit is used for creating fluid properties for both OLGA multiphase calculation as well as compositionaltracking. To obtain such properties another commercially availablepackage called PVTSIM is mandatory since the fluid properties are estimated first with PVTSIM &Īre then exported as a table file to OLGA. It must be noted that OLGA is only a solver & does not provide fluid properties as part of its package.For example, HYSYS has an inbuilt fluid property package estimator providing EOS (PR, SRK),Īctivity models, ASME Steam Tables, etc. Can be used for Multiphase flow modelling.Ģ. A sprinkler module is available to simulate fire protection systems.ġ.

Piping elements such as nozzles, orifice plates, dampers, control valves, filters etc are availableĩ. Pipe fittings data are readily available providing loss coefficient to predict losses across bends, tee'setc. Flow problems involving hydrate, wax deposition, etc cannot be solved.Ĩ. These are used to simulatesituations such as valve operations such as on-off, quick opening, etc.ħ. Pre-built functions such as Step, Ramp, Impulse functions are available. These are used forcalculating speed of sound in pipelines during transient operations such as ESD failure, pumpfailure, etc.Ħ. Piping schedules & mechanical properties such as Young's Modulus, etc are provided for commonlyknown standards such as ANSI & ASME as a built-in feature of the software. Pump modelling using pump curves areavailable & play an important role in transient calculations to calculate shut-off pressure.ĥ. For pump calculations, the inertia of both pump rotor &driver rotor are taken into account during calculations. These problems are transient & are generally part ofengineering work in oil & water pipeline jobs. Surge Analysis is a feature for estimating surge pressures & necessary surge equipment for liquidlines during liquid hammer situations. Pipe sizing using Pipenet can be applied only to single phase lines.Ĥ.

Current version of PIPENET used at Snamprogetti,Fano office is V. Although transient analysis requires a dedicatedlicense to access transient operation features. Both Transient & Steady State Runs can be made.
