Floating Production Storage and Offloading (FPSO) units play a crucial role in offshore oil and gas production. A critical component of these systems is the compressor skid, which compresses natural gas for processing or export. This case study focuses on the pulsation and vibration analysis of a three-stage reciprocating compressor
This case study examines a reciprocating compressor system operated by a leading energy company, used for compressing natural gas. The system consists of three identical compressor units, each with two stages (suction and discharge pulsation suppression devices and connected piping), supplying gas to a common header. This system had been
This case study examines the cooling water and foam systems located in two jetties (Jetty A and Jetty B) of a major industrial facility. These systems, critical for fire protection, have experienced significant issues related to water hammer effects and structural integrity. The primary objectives of this study are to
The client is operating multiple ammonia plants with similar cooling water systems made of GRE. Last year, failures were discovered in buried GRE components—specifically, an elbow and a tee—at one of the older plants. A surge analysis conducted by Dynaflow Research Group revealed that these failures were due to an
A new firewater (FW) system is being designed for a Green Hydrogen Elements facility. The plant spans a large area of approx. 2 x 1.5 km and contains multiple critical areas. The piping material is Fiber Reinforced Plastic (FRP). The main firewater ring is of DN250 and DN300 piping. The
A client designed a foam piping system that covers the three tanks in a tank pit in the harbor. The firewater system is directly connected to the general water supply. The main pipeline passes through the foam house where the water is mixed with foam. A manifold divides the mixture
A manufacturer of pulsation dampers requested Dynaflow Research Group to verify the performance of one of its discharge silencer designs in combination with a double rotary lobe gas blower by means of a pulsation study. The scope of the study consisted of a connecting straight pipe spool and the silencer
A fatigue analysis has been done for a reactor feed pressurization drum. The vessel operates under cyclic pressure ranging from 25 psig to 200 psig (1.7 – 13.8 bar), with a design life of more than 5 million cycles. Additionally, it is subjected to 200 full-range cycles from atmospheric pressure
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
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

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
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
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
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
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
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.
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
