      abstract = {Nowadays, marine vessels constitute safety-critical assets  facilitating the transport of millions of passengers and  tons of cargo worldwide. As such, they require a large  number of heterogeneous sensors dispersed in the various  on-board machinery for operational and condition monitoring  of their vital systems, such as the propulsion system.  Despite the vast availability of data from on-board  sensors, there is hardly any collaboration between the  spatially distributed sensor devices to boost vessel  performance. Up to this day, physical redundancy has been  mostly discussed in maritime literature. The use of virtual  sensors (software-based) has not been properly investigated  yet for maritime applications, despite their successful  application in other fields like aircraft control and  process control. This paper proposes a novel switching  mechanism to alternate between physical and virtual sensors  used in the primary propulsion control layer of marine  vessels aiming to compensate for the effects of sensor  faults. The switching mechanism focuses on ensuring the  safe performance of the propulsion grid after the sensor  faults occur. The software sensors are constructed using  mathematical models describing the nonlinear dynamics of  the propulsion system and the input and sensor output data.  Simulation results are used to illustrate the switching  mechanism’s performance in the case of a hybrid propulsion  system, where the different subsystems are controlled in a  distributed configuration.},
