A modelling methodology for the assessment of preventive maintenance on a compressor drive system
Zhang, Yun; Barros, Anne; Rauzy, Antoine; Lunde, Erling (Chapter, 2018)Huge rotary machines are commonly used in oil and gas processing plants for separation, compression and boosting. Their reliability is of high importance to avoid operation downtime and production loss. In this paper, we ... -
Adaptive detection and prediction of performance degradation in off-shore turbomachinery
Zagorowska, Marta; Schulze Spüntrup, Frederik; Ditlefsen, Arne-Marius; Imsland, Lars Struen; Lunde, Erling; Thornhill, Nina F. (Peer reviewed; Journal article, 2020)Performance-based maintenance of machinery relies on detection and prediction of performance degradation. Degradation indicators calculated from process measurements need to be approximated with degradation models that ... -
Condition Monitoring: Based on "black-box"- and First Principal Models
Borgan, Tom-Rune (Master thesis, 2011)Summary and conclusionsThis master thesis investigates Principal Component Analysis (PCA) methods used in the field of Early Fault and Disturbance Detection (EFDD). Statoil and ABB have in collaboration developed an ... -
Degradation Modelling for Predictive Maintenance - An Application to High Voltage Rotary Machines
Islam, Abu Md Ariful (Master thesis, 2017)Large high voltage rotary machines are commonly utilized in gas processing plants for operations such as dewatering and compression. The availability of these machines are very critical as the operation down times are ...
