In this paper a new adaptive GLR (generalized likelihood ratio) detector which is able to detect the stable periods of the operation of a vessel has been presented. To assess the performance of a vessel, the stable periods of navigation can be used only. Therefore, having only sensor measurements from the stable periods as the inputs to the system is crucial for proper functioning of an auto logged vessel performance monitoring system. Removing the 'contaminated' signals by ship maneuvering, changes in the weather condition or vessel speed would lead to an increase of the reliability of the system. The results from two VLCCs (Very Large Crude Carrier) with high and low frequency data will be shown. © 2018 IEEE.
