Surge & Water Hammer Analysis Case Studies
Extension Of A Fiberglass Cooling Water System Of A Power Plant
In the process of extending an existing power plant, the addition of a new power plant was deemed necessary. This new facility was designed around a Combined Cycle Unit (CCU), which integrated both a Gas Turbine and a Steam System.
Cooling Water Piping On A Dredger
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.
GRP Fire Fighting System
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.
A Deluge Fire Fighting System
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.
GRP Sea Water System
DRG performed a surge analysis on a seawater system classified as a Class A system under the Service Limit State (SLS) standards, following the ISO 14692 code for fiberglass systems.
Preventive Analysis Of A Fiberglass Ballast System On A Vessel
A surge analysis and static stress analysis were necessitated for an FRP ballast water system following a prior incident to prevent its recurrence.
Analysis of a 1.6 km Long Jetty Pipeline
During the construction of a 1.6 km long steel pipeline intended for the offloading of naphtha from ships at a jetty, a thorough surge analysis was undertaken.
Dynamic Stress Analysis of an Unloading Line for Pressure Surge Events
An unloading line was being commissioned for use with cyclohexane. This line featured two ship loading arms located at the end of a jetty, and from these loading arms, the unloading line ran through to two storage tanks.
Two-Phase Flow Analysis of Fuel Jetty Terminal
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.
Predicting the Flow Split Between Cooling Towers
During the construction of a 1.6 km long steel pipeline intended for the offloading of naphtha from ships at a jetty, a thorough surge analysis was undertaken.
Fire Water System on an LNG Plant: Stress and Surge Analysis
An unloading line was being commissioned for use with cyclohexane. This line featured two ship loading arms located at the end of a jetty, and from these loading arms, the unloading line ran through to two storage tanks.
Assessment of a Jetty Pipeline: Pressure Surge and Dynamic Stress Analysis
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.
Cokes Gas Network Surge Analysis
A planned modification to a cokes gas piping involves the installation of a new pipeline to a gas user and the decommissioning of an existing compressor. These changes will integrate two separate systems into one, necessitating an assessment of their impact on system stability.
LNG Bunkering System: Surge Analysis
Surge analysis in LNG bunkering systems is essential to ensure safe and efficient operations, particularly when fueling ferry ships. This analysis involves evaluating several worst-case scenarios to understand surge phenomena in a 600-meter long LNG bunkering line.
Jetty Surge Analysis for Ammonia Storage Plant
A new off-loading system is under consideration for an ammonia storage plant, designed to transfer ammonia (NH3) from a jetty to three storage tanks.
Fiberglass Replacement Pipe: Surge Analysis Case Study
In a large industrial plant located in the southern Netherlands, a complex pipeline network traverses multiple sections separated by two major highways. This network, known as the water network, incorporates both steel pipes and glass-reinforced epoxy (GRE) pipes.
