Completing the Oil and Gas Supply Chain with Certified Integration
With more than 500 oil and gas companies around the world relying on the SAP® for Oil & Gas (SAP for O&G) solution portfolio, Energy Solutions International, Inc. (ESI) sought to create a standard interface between its market leading PipelineTransporter® Gas (PLTG ) scheduling software and the SAP ERP application. In Q4 2008, the SAP Integration and Certification Center certified the interface between PLTG 4.0 and SAP ERP. PLTG also achieved "SAP Solution Manager Ready" status.

An Example of Business and Operational Integration for a Gas Pipeline
Pipeline Simulation Interest Group 2006
Transpetro faced the need to expand its vision in defining processes and systems due to changing market conditions which required the ability to respond to operational and business events in a real-time manner. Transpetro needed to marry SCADA systems with gas business systems to provide reliable operational and business integration. This paper describes the successful implementation of an integrated pipeline enterprise system for Transpetro.

Improved Capacity Utilization by Integrating Real-time Sea Bottom Temperature Data
Pipeline Simulation Interest Group 2006
Integration of up-to-date ambient temperatures enable Gassco, and other pipeline operators, to improve the usage of the available network capacity and will allow for better planning of the day-to-day capacity that can be offered for sale. This paper presents how up-to-date sea bottom temperatures were integrated in Gassco’s Pipeline Modeling System. The increased modeling accuracy enabled Gassco to commit an additional 7 million Sm3/d gas for any particular cold day.

Gas Transmission Development Strategy – a Modeling Approach
Pipeline Simulation Interest Group 2006
Sui Northern Gas Pipelines Limited (SNGPL) is the largest integrated gas company in Pakistan serving more than 2.5 million consumers covering 142 main towns in North Central Pakistan. In view of a newly discovered gas field, cross-border import options and displacement of fuel oil in the mid country power generation, Sui Northern needed a medium to long-term infrastructure expansion planning tool to effectively cater to the projected gas demand. This paper analyzes various ways in which Sui Northern used a supply-demand model along with a pipeline hydraulic simulator to update their future development strategy.

Improving Gas Load Forecast Accuracy – A Practical Approach
Pipeline Simulation Interest Group 2006
This paper examines various ways in which the data quality and utilization can be improved to more accurately predict gas demand at one of the largest gas systems in Europe. Fluxys incorporates this methodology as an integral part of the forecasting system to reduce supply risk and to drive operational efficiencies by significantly reducing forecast unavailability.

GasLoadForecaster®: Improving Forecast Accuracy to More Than 95 percent
Fluxys (Belgium) needed a forecasting tool to effectively anticipate the requirements of gas demands on its network. By reducing forecast development time and improving accuracy, Fluxys operational staff can now react more quickly to demand fluctuations or transport constraints as well as to additional shipper capacity requests.

A Case Study of How Transient Analysis Facilitates Asset Optimisation
Pipeline Simulation Interest Group 2005
Natural gas transmission networks tend to be dynamic in nature and the majority in Europe do not normally operate on a simple steady-state basis. This paper discusses how PipelineStudion was used to develop a transient model of Dublin City and how the model was subsequently and successfully used to identify additional capacity within the system.

Training tools to evaluate pipeline operator performance and to validate pipeline operational procedures
Pipeline Simulation Interest Group 2005
At installations like the OCP (Oleoducto de Crudos Pesados – Heavy Crude Oil Pipeline) in Ecuador, where the pipeline crosses high sensitivity areas, including the Amazon Jungle and the Andean mountains, the pipeline operators are subject to extreme pressure by environmental and government agencies to guarantee safe operation of the line. For OCP, being a brand new pipeline, the implementation of a training program was a very special and highly demanding project.

Expert Alarm System
Pipeline Simulation Interest Group 2005
Florida Gas Transmission (FGT) has created an Expert Alarm System (EAS)by combining SCADA data, model data, and model logic to produce integrated Gas Control alarms for the gas controllers. The EAS was implemented to provide suggestions/alarms to the gas controller as to how the system could be run more efficiently and how to avoid certain potentially undesirable situations on the pipeline.

Real Time Commercial Supervision at Petrobras
Pipeline Simulation Interest Group 2004
As part of a comprehensive upgrade of their gas shipping system, Petrobras has implemented a real-time model on several of their pipelines, integrating SCADA and model data with a new TransactionManager shipper system from EnergySolutions. The shipper system provides Petrobras with the capability to schedule, consolidate, allocate, and provide detailed energy and volume information for invoice generation.

Crude Scheduling Package For an Indian Cross-Country Crude Pipeline
Pipeline Simulation Interest Group 2003
Recently Indian Oil Corporation Ltd (IOCL - one of the majorIndian oil companies), under its ambitious Supply Chain Management (SCM) project, has taken up a project to develop and customize crude pipeline scheduling. This development takes advantage of the synergy between IOCL's vast experience in pipeline operations and EnergySolutions' software application capability. The combined package generates a feasible batch plan which meets refinery demand while using line-balancing and terminal tanks to simultaneously satisfy several optimization goals: minimizing tanker detention, minimizing in-line batch mixing, minimizing operating cost, and maximizing direct pumping (as opposed to floating operation) at the line-balancing tanks.

Optimizing Natural Gas Transportation at Transportadora Brasiliera Gasoduto Bolivia-Brasil (TBG)
Transportadora Brasiliera Gasoduto Bolivia-Brasil owns and operates the Brazilian portion of the Bolivia-Brazil pipeline. With the South American market maturing, competition is heating up. See how TBG used PipelineManager and PipelineTransporter to ensure regulatory compliance, improve service levels and maximize profitability.

Improving Pipeline Profitability at Iroquois Pipeline Operating Company
Iroquois plays an important role in connecting Canadian gas supply with Northeastern U.S. gas demand. And that’s a tough market to serve. But Iroquois uses PipelineManager and PipeLineStudio to reduce planning time by 95 percent while maximizing throughput, saving fuel and improving competitiveness.

Raising Forecast Accuracy to Greater Than 95 Percent at Dominion East Ohio
At Dominion East Ohio, one of the largest energy producers in America’s Mid-West, Mid-Atlantic and Northeast regions, EnergySolutions' GasloadForecaster enabled them to react more quickly to demand fluctuations, improving customer satisfaction and profitability.

Advanced Applications that Enhance Business and Operational Processes in the Gas Pipeline Industry
Using advanced applications, Florida Gas Transmission has been able to increase sustainable deliveries by 4% and did this without any additional compression power or pipeline installation. At the same time, they were able to reduce operational costs, representing important additional revenue and savings to the company.

Finding Success with Leak Detection Systems in a Transient Thermal Environment at the Louisiana Offshore Oil Port
Eighteen miles off of the Louisiana coast sits a terminal for the Louisiana Offshore Oil Port, a facility that unloads supertankers and transports their crude inland. A number of thermal factors exist, but the EnergySolutions leak detection system used advanced modeling to maximize the facility’s detection of expensive, dangerous leaks.

SembCorp Gas is the first commercial importer, transporter and retailer of natural gas in Singapore. EnergySolutions provided them a comprehensive combination of software solutions to fulfill the pipeline’s legal, commercial and operational objectives—integrating real-time modeling to end-user client applications to give Sembgas the tools it needed for successful global competition.

Testing the Real Time Modeling of a Gas Transmission Pipeline
Change is the only constant in a natural gas pipeline. Flows fluctuate. Compressors start and stop. Ambient conditions change. So what’s the best pipeline flow model to employ when trying to make sense of it all: Transient or Succession-of-Steady-States? EnergySolutions Ph.D.’s set out to find an answer.
