Pipeline Management Solutions

 

1. European Network Model – Gas Flow Modelling

Year: 2006

Customer: Confidential: European Energy Company

Benefits: European Gas transmission network model across 5 countries

 

Issue:

To understand how gas moves across Europe and what identify what physical bottlenecks could affect the potential flows of gas under different supply/demand/storage scenarios

 

Methodology & Results:

The SynerGEE network modelling tool was successfully used to develop an integrated model of 5 European countries gas networks using proprietary and public domain data.

 

Benefits:

Several scenarios were investigated by the client with the intention of using the network model in conjunction with in-house economic modelling tools to support strategic decision making. The model allowed the user to assess whether capacity existed for transit of gas across Europe and whether there were any physical barriers to gas transportation. This information when added to commercial pricing information allowed the client to develop a deeper insight into third party transportation, storage and shipper statements.

 

1. Hydraulic Study of the Master Gas System Expansion

Date: 2007

Customer: Saudi Aramco

Savings: Increase Capacity of the Master Gas Pipeline System

 

Issue:

GL conducted a hydraulic analysis study on the expanded Master Gas pipeline System (MGS). The expanded MGS should deliver the increased contracted flow rates of sales gas to Saudi Aramco customers in Business Plan 2007- 2013. In addition, the MGS must sustain delivery pressures and flow rates for 8 hours of survival time, after the shutdown of Hawiyah Gas Plant (HGP).

 

Methodology & Results:

Stoner Pipeline Simulator (SPS) was used to perform the hydraulic and transient analysis. The study identified bottle necks, added mainline pipes, upgraded control valves, and sized metering and filtration equipments to increase the capacity of the pipeline system. Transient analysis was conducted for survival time calculations. Temperature sensitivity cases were conducted for 70 ºF (winter), 90 ºF, and 100 ºF.

 

Savings:

The hydraulic analysis identified the optimum pipelines sizes, and added pipeline loops to avoid bottlenecks. The study provided the optimum control equipment size, and provided basis for filtration and metering stations design.

 

Questions:

1. What is the issue of European Network Model – Gas Flow Modelling?
2. What is the methodology used to resolve the issue of European Network Model – Gas Flow Modelling?
3. What is the issue of hydraulic study of the Master Gas System Expansion?
4. What is the methodology used to resolve the issue of Hydraulic Study of the Master Gas System Expansion?
5. What are the benefits of SynerGEE network modelling tool?
