A system for detecting and verifying an environmental anomaly within a shipping container (transported on a transit vehicle having an external transceiver) has wireless sensor-based ID nodes at different locations within the container and multiple command nodes mounted to the container. A first command node is programmatically configured to be operative to detect the sensor data broadcasted from the ID nodes; responsively identify the anomaly based upon the sensor data detected by that command node; and transmit a validation request to another command node. The other command node is configured to be operative to also detect the sensor data broadcasted from the ID nodes; receive the validation request from the first command node; verify the anomaly in response to the validation request and based upon the sensor data detected by the second command node; and broadcast a verification message based upon whether the anomaly for the shipping container is verified.

An access facilitation conduit or deck box is mountable on a barrier such as a bulkhead or a container vessel. The deck box allows for the insertion of the firefighting accessory such as a nozzle to a pre-established aperture in the deck box. The deck box is ordinarily sealed in the aperture a rupturable membrane or disc. The insertion of the firefighting accessory through the deck box ruptures the rupturable membrane. The deck box further allows for the provision of sensors as well as a feed of electronic data out through the deck box to a ship wide control and monitoring system. Sensors can detect fire, explosion, humidity, temperature, and the like. A firefighting accessory is for use with the deck box, as well as penetration assistance mechanisms for facilitating the penetration of the rupturable membrane.

A personal watercraft includes: a watercraft body; a seat provided in an upper portion of the watercraft body; a storage provided in a front portion of the watercraft body; an equipment case provided at a peripheral position of the storage in the watercraft body to allow equipment equipped in the watercraft body to be stored; and a hatch provided in front of the seat to openably and closably cover the storage and the equipment case.

Disclosed is a fire prevention and control system for a rechargeable battery cabin of a ship, including a detection apparatus, a fire suppression apparatus, and a control apparatus. The detection apparatus includes a first detection apparatus and a second detection apparatus, the control apparatus includes a first control apparatus and a second control apparatus, the first control apparatus is connected to the first detection apparatus, the second control apparatus is connected to the second detection apparatus, and the first control apparatus and/or the second control apparatus is configured to control whether the fire suppression apparatus releases a fire extinguishing agent. Beneficial effects: This application provides a fire prevention and control system for a rechargeable battery cabin of a ship. Detection apparatuses and control apparatuses are redundantly disposed, to provide high reliability of detection and high reliability of control, and implement a dual-path monitoring-control process of detection apparatus-control apparatus-fire suppression apparatus.

An intelligent safety supervision system applied to a ship is provided. An image acquisition module acquires high-definition images in real time. An automatic recognition module obtains ship dynamic and static data. A ship server performs feature recognition on the ship dynamic and static data to obtain a data processing result, transmits the ship dynamic and static data and the data processing result, and receives alarm indication information. An alarm module outputs an alarm. A ship client displays the data processing result, and determines whether to transmit the alarm indication information according to the data processing result. A communication module receives and transmits the ship dynamic and static data and the data processing result. A shore-side supervision system includes a ship safety supervision big data analysis platform for performing secondary feature recognition on the ship dynamic and static data, so as to obtain a secondary data processing result.
