Fault detection and diagnosis of a blade pitch system in a floating wind turbine based on Kalman filters and artificial neural networks
Cho, Seongpil; Choi, Minjoo; Gao, Zhen; Moan, Torgeir (Peer reviewed; Journal article, 2021)This paper describes the development of a fault detection and diagnosis method to automatically identify different fault conditions of a hydraulic blade pitch system in a spar-type floating wind turbine. For fault detection, ... -
Modular Adaptable Ship Design for Handling Uncertainty in the Future Operating Context
Choi, Minjoo (Doctoral theses at NTNU;2018:264, Doctoral thesis, 2018)A ship's value is dependent on its context as well as its design features. Ship designers therefore need to consider future operating context scenarios for designing a value-robust ship. The context of a ship comprises a ... -
