Pipeline Optimizer

Pipeline Optimizer

Pipeline Optimizer is an off-line software package used for pipeline engineering and planning purposes. Pipeline Optimizer employs fundamental fluid flow theory and applies standard engineering equations to simulate the complicated flow phenomena that occur on pipelines transporting crude oils, refined products, and natural gas liquids. Pipeline Optimizer performs accurate pipeline simulations to analyze the effect of various pipeline routes, pump station locations, pump unit selections and configuration, and pipe properties using a succession of steady-state model that accurately describe pipeline physics in non-transient situations. A comprehensive set of pipeline data can be configured for multiple pipelines using the graphical user interface.

Use PipelineOptimizer to:

•model and study capacity, DRA usage, operating costs, power contract usage, fuel usage, and downtime. •study realistic operational schedules and perform “what-if” scenarios •choose optimal pump combinations and DRA injection rates during a run.

Pipeline Optimizer’s wide range of pipeline modeling capabilities includes the following functions:

•User-adjustable tuning parameters to facilitate matching of historical data with Pipeline Optimizer results.
•Detailed modeling of batch liquid operations, including:
•Batch origination and pumping at the pipeline inlet.
•Batch origination and pumping at mid-line locations.
•Full stream delivery at mid-line locations or the pipeline terminus.
•Constant-percentage and fixed-rate strips or injections at mid-line locations.
•Multiple operations at the same location for a single batch.
•Specification of a fixed volume to bypass a terminal before initiating a strip or injection, between successive activities in the same batch, or after the end of the last activity.
•“Automatic” strips and injections. These strips and injections occur at the slowest possible rate that the requested volume is delivered without violating any flow limits or slowing down the main-line flow.
•Simultaneous full-line delivery of one batch and pumping of another batch. Pipeline Optimizer synchronizes the two activities to end at the same time.
•Rule-based routing of batches based on origin, destination, and product in complex pipeline networks.
•Extensive set of controls triggered by a specific time or a specific event (e.g., a batch arrival, or a certain product type being present at a certain location), including:
•Pump status controls (including both on/off and pump availability for selection by automatic pump selection routines).
•Station pressure set points.
•Line shutdown controls.
•DRA injection rate controls.
•Flow rate minimum/maximum limit controls.
•Automatic bottleneck analysis, including:
•Finding bottlenecks due to pipe yield strength or inadequate head at a station.
•Finding bottlenecks due to stations that cannot produce additional head because they would violate user-specified power consumption limits
•Recording the bottleneck for each step as well as at what fraction of the run each bottleneck condition was active.
•Modeling the effects of DRA, including: •Use of DRA rules, including amount of type of DRA injected at each station, for particular batches, or at particular times
•User specified DRA degradation through equipment, DRA suppression for laminar flow and partially for transition flow. Specification can be a factor or percentage per mile.
•Wide assortment of engineering reports, including: •AWP Profile Report showing the computed allowable working pressure at each elevation profile point, including the effects of pipe yield stress, user-defined pressure restrictions, and historical hydrostatic tests.
•Pump Combination Usage Report showing which pump combinations were used how often at each station
•Pump Detail Report showing the flow rate, generated head, pump speed, hydraulic, brake, and electric power used by each active pump at each model step.
•Pump Average Report showing averages of these quantities.
•Station Detail Report showing flow rate, power used, power costs, DRA costs, inlet, outlet, and case pressures, throttling, and line loss downstream for each station at each time step.
