Paper presented at the SPE Project and Facilities Challenges Conference at METS, February 13–16, 2011
Paper Number: SPE-141174-MS
... Abstract Emergency Shutdown (ESD) valves play a vital role in meeting production and safety requirements in a process plant. On headers of a Gathering Center (GC), ESD valve assemblies are installed to protect the downstream processing equipment from over pressure, high level and other...

Paper presented at the PSIG Annual Meeting, May 3–7, 2021
Paper Number: PSIG-2107
... may decrease due to friction or to effects related to compressibility. These surges can be problematic for automatic emergency shutdown (ESD) valves. ESD valves are configured to close automatically during a pipeline rupture to minimize spillage. These valves can also trigger on the pressure surge...

Paper presented at the ISRM European Rock Mechanics Symposium - EUROCK 2018, May 22–26, 2018
Paper Number: ISRM-EUROCK-2018-066
... ABSTRACT This article presents the basics of Empirical-Static-Dynamic (ESD) methodology for extrapolation of parameters in Rock Mechanics. The prerequisite for its successful application is to have enough data for reliable rock mass classification; to have enough testing data for deformability...

... range from very narrow margin between pore (or collapse) and fracture pressure. The density of drilling fluid is often affected by HTHP, the careful research on the drilling fluids density at HTHP is very important for precisely predicting ESD as well as controlling the downhole pressure. A utility...

Paper presented at the SPE Latin American and Caribbean Petroleum Engineering Conference, March 25–28, 2001
Paper Number: SPE-69418-MS
.... The pressure surge and thermal stresses caused by transient multiphase flow during emergency shut down (ESD) are critical design criteria for pipeline systems. Numerical methods have been developed to simulate the subsea HIPPS/ESD shut down and the ensuing system transient behaviors. These methods are able...

Paper Number: ISOPE-I-21-4164
... Abstract In this study the effect of energy saving devices (ESDs) on the forces, motions and flow field around the stern of KRISO Very Large Crude-oil Carrier2 (KVLCC2) was investigated by using Experimental Fluid Dynamics (EFD) method in regular head waves of λ/L=0.6, 0.85, 1.1, 1.35 and 1.6...
