1. 1. Component State Prediction Based on Field Data : Master Thesis in Energy System Engineering

   University essay from

   Author : Linnea Johansson; [2017]
   Keywords : Gas Turbine; Prediction Model; Failure model; Field data; Environmental attributes; Weibull Distribution; Bayesian Statistics;

   Abstract : This master thesis is part of a big project at Siemens Industrial Turbomachinery (SIT) in Finspång aimed to use the operation experience available at SIT to predict the state of the gas turbines in general and some mechanical components in particular. The objective of the thesis is to continue the development of a prediction model based on experience data for estimations of a components lifetime. READ MORE

3. 2. Survival analysis of gas turbine components

   University essay from Linköpings universitet/Statistik

   Author : Alessandro Olivi; [2016]
   Keywords : Bayesian Weibull regression; failure modes; optimal replacement time; reliability; survival analysis;

   Abstract : Survival analysis is applied on mechanical components installed in gas turbines. We use field experience data collected from repair inspection reports. These data are highly censored since the exact time-to-event is unknown. We only know that it lies before or after the repair inspection time. READ MORE
