Data-driven Modeling of Ship Motion Prediction Based on Support Vector Regression
Kawan, Bikram; Wang, Hao; Li, Guoyuan; Chhantyal, Khim (Journal article; Peer reviewed, 2017)This paper presents a flexible system structure to analyze and model for the potential use of huge ship sensor data to generate efficient ship motion prediction model. The noisy raw data is cleaned using noise reduction, ... -
Online Drilling Fluid Flowmetering in Open Channels with Ultrasonic Level Sensors using Critical Depths
Chhantyal, Khim; Viumdal, Håkon; Mylvaganam, Saba (Journal article; Peer reviewed, 2017)In drilling operations, non-Newtonian drilling fluid is continuously circulated in a closed loop. One of the ways to monitor and regulate drilling operations is by accurately measuring the flow rate of circulating drilling ... -
Sensor Data Fusion based Modelling of Drilling Fluid Return Flow through Open Channels
Chhantyal, Khim (Doctoral dissertations at the University of South-Eastern Norway;10, Doctoral thesis, 2018-09-20)In drilling oil & gas wells, pressure control is essential for several reasons, but pri-marily for safety. The wellbore pressure should be maintained within the pressure window to avoid the kick and fluid loss while drilling. ... -
