Case studies and project highlights from our consulting work.
Vibration Enhancement In An Oil Wash Line
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
Preventive Analysis Of A Fiberglass Ballast System On A Vessel
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
A Deluge Fire Fighting System
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
GRP Fire Fighting System
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
Assessment of potential internal explosion in H2-generation systems
Hydrogen generation equipment has an inherent risk for internal explosions, posing an issue to safety. The hydrogen piping and equipment are required to withstand internal explosions by limiting the damage to deformation. Although this disqualifies the component for future use, safety is not compromised. The objective was to find a
Engineering District Cooling and Heating Systems
A District Cooling System (DCS) fits the sustainability challenges that our society is challenged with. It provides cooling capacity from a central facility; chilled water is distributed from this central facility to multiple buildings through a network of underground pipelines. The central cooling facility works more power efficient and it
Development of a Biodiesel facility Rotterdam
Shell is building a biofuels facility at the Shell Energy and Chemicals Park Rotterdam, the Netherlands (Pernis Refinery) that will have an annual production capacity of 820,000 tonnes of biofuel. The biofuels facility is expected to start production in 2024. The project is ranked at position 7 in the top
Pipeline Filling
Why Pay Attention to a Line Filling Process? During a start-up/line filling process a wave front of fluid progresses it’s way through the empty* parts of the line. However, when this front is required to change direction through bends the change in momentum generates an unbalanced force, this unbalanced force
Structural Displacements due to Hogging and Sagging
What is Hogging and Sagging and what are the effects on piping? When waves pass over the length of a ship, the ships profile rises and bows following the peaks and troughs of said wave due to the changes in bouyancy along the length. This effect is known as hogging
Cooling Water System Improvement at Ammonia Plant Australia
For an ammonia plant in Western Australia, cooling water is supplied by a Sea Cooling water (SCW) as well as a Fresh Cooling Water (FCW) system. Both piping systems were constructed out of fiberglass material with pipe diameters of up to 72”. Heat exchangers acts as the interface between the
Root-cause Failure Analysis
Dynaflow Research Group has performed a root-cause analysis for a cooling water system that had 3 recent leakages. The failures were in 10” pipe and 18” pipe made of fiberglass material. Dynaflow Research Group reviewed the material data, engineering analyses and failure info and determined the root-causes of the failures.
Review and Risk-Assessment of Abandoned Coolwater System
Dynaflow Research Group provided consultancy services to finalize the construction of cooling water (CW) system of a chemical plant in the Texas, USA. The construction was interrupted for a period of 2 years. The CW system was constructed out of fiberglass material. A full design review was performed for the
CO2 Capture and Storage Design Project
Air Liquide and BASF want to capture and store the CO2 of five factories at the BASF site in Antwerp. Dynaflow was requested to perform a feasibility of the CO2 transport line that takes the CO2 from the five factories at the BASF site and transports it outside the BASF
Geothermal Energy Production Support
The geothermal installation Trias Westaland, with presently 2 geothermal doublets, produces 40MW of sustainable thermal energy that is supplying heat to 54 greenhouses and several hundreds of households. Geothermal wells typically produce gas along with the hot saline water that is pumped up from large depths. Therefore, most geothermal production

CFD analysis of the two-phase flow in slug catcher finger
Introduction The two-phase flow in the finger pipe of a finger-type slug catcher is analyzed using CFD techniques. When the fluid flow in the inlet header manifold is evenly distributed among the different fingers, it is necessary to obtain stratified flow to promote liquid separation. Analysis The two-phase flow in
CFD analysis of a finger-type slug catcher header
Introduction The flow in the header of a finger-type slug catcher is analyzed using CFD techniques. In order to design a high-performance finger-type slug catcher, it is necessary that the fluid flow in the inlet header manifold is evenly distributed among the different fingers. Analysis A detailed flow analysis by
