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.

Recently, fatigue cracks were discovered in the first-stage discharge line’s small-bore instrumentation branches of a hydrogen compressor. Initial investigations pointed to excessive out-of-plane vibrations as the primary driver of these failures. While the system was originally installed in 1995 with a pulsation study, and further axial supporting was added in
In industrial effluent systems, piping integrity is often threatened by the geotechnical behavior of the surrounding soil. This case study examines the peer review of a stress analysis for effluent pipelines situated between valve chambers.

This case study presents the fatigue assessment of the 28L oil separator (Atlas part number 1625481501), performed to verify the vessel’s durability under cyclical internal pressure in accordance with the AD2000 S2 standard. The separator is subject to a cyclic pressure loading from atmospheric pressure up to 15 barg, which
This project examines the root cause of increased vibrations observed in the control valve 670FC005-VC at Shell Pernis following its replacement with a new valve from a different manufacturer. The resulting vibrations led to a critical mechanical failure at the connection between the valve stem and the actuator. The objectives
At BP Geel, a new extension of the fire protection system experienced operational failures during start-up due to surge effects. A similar incident with line AFW-023025 had previously prompted a surge analysis, leading to the current study focused on the adjacent foam system, line AFW-023024. The foam line, running nearly
At the BP Geel facility, a previous failure of the fire protection system during start-up prompted a detailed investigation into surge effects within the network. The incident occurred on line AFW-023025, and subsequent studies identified hydraulic transients as the primary cause. Given the similar configuration and operating principle of the
The ONE GUYANA Floating Production Storage and Offloading (FPSO) unit has been designed to operate in deepwater conditions with a production capacity of 250,000 barrels of oil per day. The FPSO is designed for a 20-year operational life, handling complex processes including water and gas injection. Previous projects highlighted the
During this project the optimal wearplate thickness for pipe supports on the FPSO Maria Quiteria was investigated, aligning with the Yinson project specifications.

On the Goliat Floating Production Storage and Offloading (FPSO) unit, significant vibration and cavitation phenomena were observed downstream of control valve 71PV1103 on the minimum flow line of pump B during maximum flow conditions. Additionally, pressure surges were reported during system start-up through this minimum flow line. Such issues posed
The Petrojarl I Floating Production, Storage, and Offloading (FPSO) facility, in operation since 1986 in the North Sea, underwent critical modifications to prepare for deployment at the Atlanta oil field offshore Brazil.
