Propeller ventilation is one of the main reasons for the widespread mechanical failures of thrusters, with costly repairs and increased vessel down-time. Most of existing ventilation detection methods have been designed based on the dynamics/control modelling of water and the propeller, and they generally require information or accurate estimates of vessel specific parameters. The main challenges...
Marine operations face the major challenge of increased complexity. Much more data are being collected for diagnostic and monitoring purposes with sensors on board a vessel. However, due to the lack of easy data presentation and interaction, the crew members are overwhelmed by the large volume of information and alert messages, causing serious information overload problems. In this paper, we explore...
Complexity and specificity of monitoring sensor data from marine operations brought a majority of challenges of how to evaluate the visualizations of such sensor data. It's urgently needed to develop and implement new evaluation methods to assess the visualization of maritime data. In this paper, we explore both quantitative and qualitative evaluation approaches to define evaluative metrics of our...
