Study on Pigging Process Analyses and Control Methods for Moisture Gathering Lines: Study in Puguang Gas Field, China
Publisher: ASCE
Abstract: The moisture gathering line of the Puguang Gas Field in China renders it prone to accumulating liquid at certain points due to topographic differences. Under operational conditions of pigging, liquid slug volumes, end ...
Simulation and Replication of High-Pressure Hydrocarbon Pipeline Commissioning under Large-Drop Undulating Environments
Publisher: American Society of Civil Engineers
Abstract: The BoZi (BZ) hydrocarbon pipeline is a large descending pipeline that transports a mixture of condensate and light hydrocarbons. It is prone to evaporation during transportation, posing safety risks during commissioning. ...
Predicting Wall Deflections for Deep Excavations with Servo Struts in Soft Clay
Publisher: ASCE
Abstract: Axial forces can be artificially adjusted in deep excavations braced with servo struts to reduce excavation-induced deformations. The interactions among the servo strut, retaining wall, and retained soil must be considered ...
Laboratory Investigation of Plough Sole Reformation in a Simulated Paddy Field
Publisher: American Society of Civil Engineers
Abstract: The study aimed to determine the number of cultivation cycles required to reform the plough sole once it has been destroyed or removed from the paddy. An ad hoc infiltration column experiment, which is a cylinder of
Low Cloud–SST Feedback over the Subtropical Northeast Pacific and the Remote Effect on ENSO Variability
Publisher: American Meteorological Society
Abstract: Low clouds frequent the subtropical northeastern Pacific Ocean (NEP) and interact with the local sea surface temperature (SST) to form positive feedback. Wind fluctuations drive SST variability through wind–evaporation–SST ...
Numerical Investigation of the Effect of Stratum Hydraulic Conductivity on Performance of Deep Excavations in an Aquifer–Aquitard System
Publisher: ASCE
Abstract: Engineering practices indicate that stratum hydraulic conductivity (SHC) has a significant influence on deep excavations. However, this influence has been ignored in previous studies with undrained analyses. In this study, ...
