Abstract

 

The article describes issues related to the ship motion parameters estimation in storm conditions as available onboard the ship (at the bridge), demonstrating the necessity of taking into account the actual wave spectrum and registration of pitching at the actual loading conditions of the ship and outlining the method that allows to obtain the actual wave spectrum based on wave field image processing on the screen of the radar station. Furthermore, the article shows the possibility of automated image processing of the radar image based of the pattern recognition software, describing the combination of hardware and software tools for the registration of pitching and obtaining natural periods of pitching by pitching time-series record processing. The procedure is proposed to support intelligent navigation decisions in storm conditions according to the data obtained from the records of pitching and pitching natural periods. Finally, the proposals for improvement of the normative framework in terms of radars and obtaining information on the transfer function of pitching at typical load conditions are made.

 

Keywords: actual wave spectrum, radar image of the wave field, record of vessel pitching, transfer function of pitching.
