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.

At an oil refinery plant in Saudi Arabia, a fiberglass-reinforced plastic (FRP) pipe fire water system has been installed, predominantly buried underground. Since its installation, the system has experienced several failures. DRG was tasked with conducting a comprehensive pipe stress analysis to assess the system’s integrity. This analysis focused on
In a new industrial process, an existing floating head heat exchanger is being repurposed. The operational conditions involve cyclic loading, which were not originally considered during its design phase. To evaluate the impact of these cyclic loads on the heat exchanger, Dynaflow Research Group conducted a comprehensive fatigue analysis. 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. The system, constructed using Glassfiber Reinforced Epoxy (GRE) pipes, underwent a dynamic response analysis to account for the largest and most critical unbalanced forces. Surge Analysis The existing firewater
This case study examines the detailed fatigue stress analysis conducted on a heat exchanger used to heat Polyol before it entered a refinery reactor. The complex 8-pass, U-tube configuration with a flanged stationary tube sheet required thorough investigation to ensure operational integrity and longevity. Analysis Methodology Engineers identified and analyzed
A fuel jetty terminal operator expressed concerns about potential two-phase flow issues during off-loading operations. The client indicated that trapped nitrogen used for purging lines could mix with the liquid being off-loaded when empty ship tanks were flushed with inert nitrogen. This scenario raised the possibility of slug flow development,
In this case study, a number of critical sections in an already installed fire water system were selected for review. At the time of the analysis, earlier on-site interventions had already been made, motivated by pipe failures. The analysis aimed to determine if additional interventions were necessary. Analysis Based on
This case study describes the stress analysis performed on a firewater piping system located in the Middle East. The system was constructed using Glassfier Reinforced Epoxy (GRE) pipes. Most of the piping was buried underground and included several connections to above-ground steel piping, fire hydrants, and similar equipment. Analysis The
Introduction At a Flow Station in Nigeria, vibration issues were observed in the suction and discharge headers, as well as the pump recirculation line. To address these concerns and identify potential underlying issues, DRG conducted a comprehensive pulsation analysis combined with a mechanical response assessment. Analysis A stress model was
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
Introduction In this case study, we encountered undesirable vibrations in the downstream line of an angle control valve within a wash oil line. Initially, the upstream wash oil boasted a pressure of 150 bar and a temperature of 400°C. However, downstream of the valve, there was a significant pressure drop
Introduction A surge analysis and static stress analysis were necessitated for an FRP ballast water system following a prior incident to prevent its recurrence. The ballast system’s function was to redistribute water among compartments to balance oil storage. Analysis Surge Analysis One of the main objectives of the surge analysis
Introduction In the North Sea, three monopiles were equipped with a deluge fire-fighting system. To ensure its effectiveness, a water hammer calculation was carried out. This system comprised a two-ring fire water setup, with four sprinkler lines linked to the lower ring. Additionally, considerations were made for potential future scenarios
Introduction In the context of a gas facility, the addition of new units necessitated the enhancement of the existing firewater system. This system was designed to ensure a reliable source of firewater storage, make-up, and distribution capacity to effectively address the plant’s fire safety requirements. Analysis The objectives of the
Introduction In this case study, the focal point was addressing the high vibration levels observed in the process piping extending from a heat exchanger to a separator. Concerns were raised regarding the potential for dynamic stress to induce fatigue failures in the equipment nozzles over time. The flow within the
Introduction In this case study, we addressed a notable vibration issue observed in the main 16” line at a chemical plant, which was suspected to stem from slug flow. Specifically, the concern centered around the 16” pipe connection linking a low-temperature separator and a heat exchanger. Dynaflow Research Group was
Introduction This case involved fulfilling a client’s request to perform a surge analysis and static and dynamic stress analysis about the cooling water lines and associated supporting steel on a dredger. Analysis The objective of the surge analysis was to define the cooling water flow rates during a steady state
