..., control room and commercial functions. In each of these traditionally siloed spaces, simulation solutions are employed that fulfill the engineering, operational and business requirements for existing natural gas pipeline infrastructure. As we navigate the global trend toward a more carbon neutral energy...

... to simulate the impact that evaporation and condensation have on the behavior of pipelines. It also discusses the results of two case studies that were performed to test the accuracy and efficiency of the new method. In one of the case studies, the new method was used to simulate the behavior of a commercial...

..., are not similar. Training that uses the modeling software display while controllers normally work with SCADA displays could lead to confusion, delayed response times, and additional training to learn the unfamiliar interface. The effectiveness of the training simulation would thereby be limited. Features...

... Abstract Fast turnaround on individual gas and liquid simulations can be crucial for critical operational or planning decisions, however complex transient simulations for large systems can be slow. Surge analysis studies can be slow too, due to the necessarily small time steps and knot spacing...

... in a straight pipe with 1-inch (25.4 mm) ID or its passage over a Tee junction is investigated. Through CFD simulations, multiphase flow characteristics such as the water distribution around the pig are examined. Afterward, based on the water concentration, the phase-wetting condition would be identified which...

... this is very high. The transient surge pressures created in these cases can become extreme to the point of exceeding the maximum operating pressures of the pipe. When performing transient simulations, it is important to consider the fluid with higher viscosities that have been kept in the pipes...

Alongside the technical challenge of these studies; a key factor was generating justifiable rationalisation of all permutations of operating scenarios into a manageable quantity of worst-case simulations for a multi-tank and multi-jetty site. Combined...

.... We will talk about our experience of creating a tool that assists control room dispatchers in quick reaction to changing transport situation. This tool we call Net Schedule Management (or NSM in short) and it consists of two modules - one that archives a gas day simulation and cleans bad SCADA data...

... controllers or check valves is often assumed. However, these simplifications can lead to inapplicable solutions. The aim of this article is to optimize the transition between two steady states using a sufficiently realistic simulation, with a complete optimization lasting no more than 30 min. It means to get...

The Mexican National Center for Natural Gas Control, CENAGAS, required a mechanism to include the new agreements in pipeline simulations. This paper explains the pipeline simulation techniques...

... knowledge of risk calculations, pipeline simulations and assumptions are a prerequisite to be able to evaluate whether a change is significant with regards to risk level. The pipeline risk assessment must be well known by the operator to ensure solid risk management for a pipeline in operation. This implies...

This paper explores the multiphase model and computation algorithms used to simulate multiphase flow with sand particles through a subsea pipeline to predict the pressure gradient, transport velocity, and sand deposition. Being able to predict sand accumulation and understanding real-time sand velocity...

During the front-end engineering and design (FEED) phase of a recent project, dynamic multiphase pipeline simulation showed that the oil pipeline would experience slugging across a wide range of operating conditions when fuel gas is spiked into the oil export pipeline. To mitigate slugging...
