    • Failure intensity of offshore power plants under varying maintenance policies 

      Perera, Lokukaluge Prasad; Machado, Mario M.; Valland, Anders; Manguinho, Diego A.P. (Journal article; Peer reviewed; Tidsskriftartikkel, 2019-01-06)
      System reliability of an offshore power plant with several gas turbine engines is analyzed in this study to understand the failure intensity of a selected gas turbine engines under varying maintenance activities. A set of event data of a selected gas turbine engine is considered to identify system failure intensity levels, where unknown maintenance actions were implemented (i.e. various repairs ...
    • Ship Performance and Navigation Data Compression and Communication under Autoencoder System Architecture 

      Perera, Lokukaluge Prasad; Mo, Brage (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-21)
      Modern vessels are designed to collect, store and communicate large quantities of ship performance and navigation information through complex onboard data handling processes. That data should be transferred to shore based data centers for further analysis and storage. However, the associated transfer cost in large-scale data sets is a major challenge for the shipping industry, today. The same cost ...
    • Ship speed power performance under relative wind profiles in relation to sensor fault detection 

      Perera, Lokukaluge Prasad; Mo, Brage (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-11-19)
      Statistical Data analysis and visualization approaches to identify ship speed power performance under relative wind (i.e. apparent wind) profiles are considered in this study. Ship performance and navigation data of a selected vessel are analyzed, where various data anomalies, i.e. sensor related erroneous data conditions, are identified. Those erroneous data conditions are investigated and several ...
