Bottleneck Analysis

Bottleneck Analysis

Where transmission or distribution companies see an opportunity to increase the system’s capacity, Bottleneck Analysis module can be used together to provide the best feasible solution for the expansion project, be it construction of a loop pipeline, compressor station(s), or a pipeline interconnection.

  • Identify and calculate bottleneck in sections of the Pipeline
  • Calculate different alternatives for the expansion
  • Economic and cost index comparison
  • Report all different alternatives

System Availability

System Availability

A powerful and flexible module for an availability study that performs Monte Carlo simulations. Compressor unit failures, their frequency and scenarios, are identified and each scenario is thermoshydraulically simulated and its capacity under failure is quantified. The frequency of failures versus capacity under failure will allow the evaluation of the compressor-system availability, and also support decisions on the provision of an adequate level of redundancy (stand-by units) for gas pipelines.

  • Failure and availability analysis for the Gas Compression System
  • Statistical methods and Monte Carlo Simulation
  • Define economic level of redundancy for the Pipeline project
  • Optimize installation of standby Compression Units at the Compressor Stations
  • Realtime on-screen graph partial results calculation

FineTuning and Failure Analysis

FineTuning & Failure Analysis

This module of GasPipelineExpansion is very helpful to incorporate to the pipeline model the actual compressor stations locations as their mileposts are confirmed or changed from field surveys. The user can easily configure and run thermohydraulic simulation for failure analysis setting compressor units’ status to ON, OFF and Standby.

  • Analise and run failure scenarios
  • Show the impact on the Gas Compression System capacity as you turn on/off different Compressor Units

Compressor Station Optimization

Compressor Station Optimization

This module does compressor station optimization and defines the optimum arrangement of compressor units based on the criteria selected by the user be it maximum line pack or lowest fuel demand. It is of key importance for evaluating proposals from equipment vendors and checking the best fit for the station. Reports are easily issued from this module.

  • Models compressor performance curves and drivers
  • Build a compressor station with different compression units
  • Select best arrangement of Compressor Units to be allocated with a required capacity

Capacity RampUp Analysis

Capacity Ramp Up Analysis

New gas pipeline projects generally do not start operation with full capacity and it is necessary to determine the best configuration for compressor stations and compressor units to cope with the capacity ramp-up through the first years of operation, along with the schedule for installation of compressor stations and compressor units. The GasPipelineExpansion approach optimises CAPEX cash flow and makes the project more competitive.

  • Identify optimum installation schedule for the Compressor Station and Compression Units
  • Define transportation capacity curve for the project
  • Optimize Compressor Station CAPEX schedule
