This invention relates to a computer-model-based automatic safety assessment method and system for ships, belonging to the field of ship control system technology. The safety assessment method and system of this invention establish a full-ship model, including models of each system, equipment, pipeline, and cable on board, as well as the logical dependencies between the functions of each piece of equipment and system. Then, in the event of an accident, based on this full-ship model, especially its logical relationships, it calculates the direct damage caused by the accident and the functional status of each ship system. Based on this, it issues damage control and recovery operation suggestions. Furthermore, it can determine in real time whether the ship meets the technical specifications for safe return to port based on the results of damage control and recovery operations, issuing judgment results information as a reference for formulating the ship's subsequent navigation plan. This avoids situations where accurate judgments cannot be made in complex circumstances, ensuring the navigational safety of ships through efficient and accurate automatic safety assessment.

This invention relates to the field of ship safety, specifically to a multimodal perception and UAV-assisted ship damage control and firefighting system. The system includes an intelligent perception network subsystem; a multimodal perception data stream acquisition subsystem; a central intelligent decision-making subsystem; a decision-making scheme generation and dynamic adjustment subsystem; a UAV-assisted firefighting subsystem; and a collaborative execution and data feedback system for fire response. This invention utilizes a data fusion engine to perform layered fusion of multi-dimensional perception data, integrating environmental parameters, images, videos, vibration signals, and other information. Combined with a digital twin baseline model of the ship's entire lifecycle, it can accurately determine the type, severity, core location of the fire source, and spread trend, clarify the protection priority and avoidance areas for critical equipment, and provide comprehensive and multi-dimensional data support for decision-making.

The application provides a ship surface intelligent cleaning robot based on a YOLOv8 architecture, and belongs to the technical field of ship maintenance equipment, and comprises a visual perception module, a composite adsorption module, a motion execution module, a cleaning operation module, a control hub module and a machine body bearing module for carrying each module, wherein the composite adsorption module is composed of an adjustable U-shaped permanent magnet and a propeller negative pressure adsorption structure, the cleaning operation module comprises a telescopic mechanical arm, a cavitation jet nozzle, an ultraviolet decontamination device and a protective cover arranged at the front end of the integrated bearing module. The control hub module is signal connected with each module, and controls the collaborative operation of each module. The application takes the cavitation jet technology as a cornerstone, and further combines the ultraviolet radiation technology, so that the biological adhesion layer stripping and micro-damage control are realized by optimizing the jet parameters (pressure, frequency), 99% of biological adhesion can be removed, the decontamination rate can be as high as 95%, and the decontamination rate is improved by about 35.7% compared with the prior art.
