WebAug 13, 2024 · Dynamic Positioning System (DPS) is a critical component of marine vessels and floating platforms that are used in offshore operations. It is a computer-controlled system that automatically maintains a ship’s position and heading using thrusters fitted to the ship. Reliability assessment of DPS can be analyzed through conventional … WebFirst, the dynamic fault tree analysis (DFTA) method was used to establish a DFT characterizing the dynamic interaction for the DPCSNR. Then, the dynamic Bayesian network (DBN) method was used to transform the DFT into the initial DBN (IDBN) model characterizing the dynamic interaction and time dependence for the DPCSNR.
WebThe Emergency Diesel Generator (EDG) is a critical and essential part of the Nuclear Power Plant (NPP). Due to past catastrophic disasters, critical systems of NPP like EDG are designed to meet high dependability requirements. Therefore, we propose a framework for WebFTA analysis involves five steps: Define the undesired event to study. Definition of the undesired event can be very hard to uncover, although some of the...
