![]() Usually located at the end of the jetty, the ERC valve is designed to close quickly and disconnect the hose that leads to the ship. Another valve, the Emergency Relief Coupling (ERC) valve, operates when the system needs to be shut down in an emergency such as a storm. The normal shut-off valve (NSV) operates on a daily basis, closing when the tanker is full. Loading systems normally have two valves, which can be the source of problems. ![]() Carrying Lube Oil, the maximum pressure permitted was 15 barg. This study was conducted for a Korean engineering company, who needed to design a 6 km steel pipeline from a refinery out along a jetty to a tanker ship. The use of GRE (glass reinforced epoxy) pipes, which are less elastic than steel and use adhesives which potentially lead to weaker joints, can further increase the need for careful analysis. Furthermore, as such systems are usually located near the sea, a leak of hydrocarbon material could potentially lead to an environmental disaster. ![]() Loading systems are often susceptible to suffer from pressure-surge problems. ![]() PIPENET ® Leading the Way in Fluid Flow Analysis Application Bulletin – Process Industry PIPENET ® Transient Module Case Study JETTY LOADING SYSTEM BACKGROUND The modelling of loading systems is a major application for PIPENET VISION Transient Module.
