Pipeline Studio™ (gas)’s transientanalysis capability enables Planners andOperators to analyse potential gasacquisitions. By defining the dynamicthroughput capacity and demand, theuser is able to make decisions on productpurchases. This enables system planningand forecasting, both of which have adirect impact on contracted deliveries.Changing system demand facilitates thescheduling of compressor operations andalso assists in the development of a betteroperating strategy for significant fuelsavings and overall cost reductions.Pipeline Studio™ (gas) can be used ateach stage of the planning cycle toexplore alternatives and make economiccomparisons.

Pipeline Studio™ (gas) allows you tointeract with your simulation. DuringA transient simulation you can changeset-points and constraints and see theimmediate effect on hydraulic profiles.This functionality provides unique insightinto often complex pipeline dynamics.

With both steady-state and transientanalysis capability, Pipeline Studio™combines a design, engineering andplanning tool into one package.

Applications Overview

Pipeline Studio™ (gas) has proven itselfto be an extremely valuable addition tothe analysis capabilities of EnergySolution’s portfolio of off-line pipelinesimulation products.

Pipeline Studio™ (gas) is used in designapplications for pipeline and equipmentsizing, specifying equipment locations,deliverability analysis and in analysingstart-ups and shut-downs. In operationalapplications Pipeline Studio™ (gas)facilitates improvements in planning, fueluse, equipment scheduling, peak dayanalysis, leak evaluation, upset analysisand in Operator training.

Problem solving under Pipeline Studio™(gas) normally takes the form of CaseStudies, where a User runs severalsimulations and compares the results. Forexample, the base case for an existingsystem would be a simulation undernormal steady-state operating conditionstogether with a simulation of any normallyoccurring time-varying phenomena. Bysimulating changes in pipeline operationresulting from design modifications (orfrom dynamic conditions, depending onwhich is being analysed) and comparingthe results to the base case, a User candetermine the most effective designchange or modification to operationalprocedures.

Typical Pipeline Studio™ (gas)Applications include:

Determining Maximum PipelineThroughput – Pipeline Studio™ (gas)allows a user to evaluate the optimalconditions for product delivery, taking allpipeline constraints into account. Theuser compares and evaluates differentoperational scenarios in order todetermine what increase in flow may bepossible without violating the minimumcontract pressure at specific points ofdelivery.

Economic Comparisons – By evaluatingthe cost-effectiveness of, for example,adding parallel loops or installingadditional compressors, PipelineStudio™ (gas) can determine the costimpact of defined alternatives of flow,pressure and other variables along apipeline system through a set ofcomparisons.

Computing System Survival Time –Survival Time is the interval between thetime an upset condition first occurs andthe time when some critical operatingconstraint has been violated. By trackingpressure and flow throughout a system,Pipeline Studio™ (gas) identifies whenand where constraints are being violated.Case Studies then determine whichcorrective actions will most effectivelyextend survival time.

Improving System-wide Fuel Economies –Shutting down compressors and shiftingthe load enables compressor horsepowerto be optimised, thus conserving fuel. Bysimulating demand and supply factors,Pipeline Studio™ (gas) determineseconomic compressor unit selections, andprovides a detailed simulation of eachcompressor unit and its associated driver,including the transient effects ofwithdrawing compressor fuel from thepipeline.

Improving Delivery – Simulating themanipulation of delivery set-points in theevent of loss of supply to a networkassists the User in maintaining criticalpressures within a pipeline system.

Simulation of Pipeline Leaks and Studiesof Transient Response – PipelineStudio™ (gas) leak simulation enablessimulation of hypothetical leaks in orderto determine the volume of gas lostbetween rupture and detection, thetransient response to a corrective actionand the total volume of gas lost duringthe event. A study will identify thefeasibility of installing a leak detectionsystem.

Predicting the Environmental Impact ofLeaks – Total leak volume calculations byPipeline Studio™ (gas) as part of a studycan be used in subsequent atmosphericdispersion calculations to determineground level contamination.

Surge Simulation – Leaks, valve closures,compressor start-up and shutdown can allcause potentially damaging pressuresurges in a pipeline. Simulating withPipeline Studio™ (gas) enables a User todetermine whether pressure surges willexceed design criteria at any point in anetwork and evaluate methods ofsuppression.

Analysis of Start-up and ShutdownProcedures – Comparison of differentstart-up and shutdown procedures willhelp to determine those procedures thatmost effectively accomplish the objectivesof the pipeline system. Compressors,regulators and other modelled equipmentcan be scheduled in any time-varyingcycle so that the effects on the networkcan be studied.


Heating Value Delivery – By tracking fluidcomposition or fluid qualities throughoutthe pipeline over time, a user can studyhow various fluid combinations will affectthe heating value for each delivery point,and thus ensure that contractrequirements are met.

Analysis of Pipeline Delivery Capabilities –This can include the determination ofwhether a pipeline will meet futuredemand with existing equipment levels,and also the investigation of producttransfer strategies and compressorscheduling requirements.

Operator Training – Functioning as an off-line system simulator in tandem with areal-time pipeline system, PipelineStudio™ (gas) enables new users tofamiliarise themselves with normalpipeline operation and to be trained in themanagement of transient operatingproblems without affecting real-timesystem performance.

Increased Profitability Through ReducedCosts –− Optimisation of compressor

schedules can minimise fuel costs.− Fuel usage evaluations can enable

optimisation of operational modes.− Simulation of anticipated operating

scenarios facilitates faster reactiontimes to system upset conditions,more accurate evaluation of gasacquisition and custody transferopportunities.
