Data-Driven Approaches to Diagnostics and State of Health Monitoring of Maritime Battery Systems
Vanem, Erik; Liang, Qin; Ferreira, Carla; Agrell, Christian; Karandikar, Nikita; Wang, Shuai; bruch, maximilian; Bertinelli Salucci, Clara; Grindheim, Christian; Kejvalova, Anna; Alnes, Øystein Åsheim; Thorbjørnsen, Kristian; Bakdi, Azzeddine; Kandepu, Rambabu (Chapter, 2023)Battery systems are increasingly being used for powering ocean going ships, and the number of fully electric or hybrid ships relying on battery power for propulsion and maneuvering is growing. In order to ensure the safety ... -
Data-Driven Prediction of Ship Propulsion Power Using Spark Parallel Random Forest on Comprehensive Ship Operation Data
Liang, Qin; Vanem, Erik; Knutsen, Knut Erik; Zhang, Houxiang (Chapter, 2022)This paper aims to propose an efficient machine learning framework for maritime big data and use it to train a random forest model to estimate ships’ propulsion power based on ship operation data. The comprehensive data ...
