We are glad to announce that the BOSfluids course has been updated. The course has been restructured and expanded to provide insights on the latest version of the BOSfluids program.

The basis for reliable fiberglass piping systems are the specifications that lay out the requirements to the system regarding material quality, engineering, installation and inspection and test plans.

Cooling water installations are designed to cool an installation in the event of a nearby fire. This can be necessary if the contents of a tank or pressure vessel are likely to expand with heat. We can use BOSfluids to perform hydraulic calculations of steady state flows in a cooling water system that includes many deluge nozzles (sprinklers).

The latest BOSfluids release brings a new, low-cost license option that is aimed at users who are primarily interested in performing steady state analyses.

Dynaflow Research Group has recently performed several level 1 and 3 assessments resulting in either extended service lifetimes or recommendation of component replacement.

The new BOSfluids release brings many small and large improvements to its user interface that make it even more efficient and versatile.

Dynaflow proudly presents a new online training course: “Pipe Stress Analysis”.

A gas compressor station, comprising five similar compressor units connected by an inlet and outlet header, is planned for offshore construction in Mexico. Each unit features three compressor stages that elevate the gas pressure from ambient levels to 95 bar. This substantial pressure increase is accompanied by a significant temperature

Dynaflow Research Group (DRG) conducted comprehensive pipe stress analyses for a large oil and gas extraction facility. This facility comprises three onshore flow stations, one offshore flow station, and a gas export compressor station. Crude oil and gas are transported from the wells to the flow stations, where the crude

A steel pipeline was under construction for offloading naphtha from ships arriving at a jetty. A surge analysis was conducted to evaluate the pipeline’s capability under various transient upset scenarios. Following this, a dynamic stress and flexibility study was performed based on the calculated pressure surges. Analysis A transient one-dimensional

A comprehensive stress and surge analysis was performed for the firewater piping system of an LNG plant located in South America.

Introduction In this case study, we explored the pulsation and vibration phenomena at a gas compression station equipped with four centrifugal compressors. These compressors generate flow pulsations due to the action of the impellors, which can excite the system’s acoustic and mechanical natural frequencies. To understand and evaluate the system’s

Introduction During the start-up and normal operation phases of a Gasoil Hydrofiner system, significant vibrations were observed in its piping. These vibrations, described as “large amplitude,” were particularly concerning. The unit’s piping was divided across four separate pipelines. Analysis Upon examining the system under various process conditions, it was determined

Pressure surges ocurr in piping systems whenever there are sudden changes in flow resistance from steady operation. Surges can cause significant damage, also at locations far removed from where they are initiated. For large or complex piping systems, this can make their impact challenging to predict without specialist analysis. Dynaflow
