  • Publication number: 20240179214
    Abstract: A crew support system includes a communication terminal to collect information about a device on a watercraft and transmit the information, a server to receive the information from the communication terminal, and a client terminal to communicate with the server. The communication terminal includes a periodic transmission mode to transmit the information to the server in a periodic transmission cycle, and a high-speed transmission mode to transmit the information in a cycle shorter than the periodic transmission cycle. The server determines a status of the watercraft, and transmits information about measures to address the status, to the client terminal, based on the result of the determination. The client terminal provides the information received from the server to a user. The server determines whether or not a recovery operation by the crew is possible, and transmits information about the result of the determination regarding the recovery operation to the client terminal.

  • Patent number: 11243539
    Abstract: An imaging system for a ship includes cameras mounted on the ship and spaced apart at a predetermined interval, and a controller that combines peripheral images of the ship captured by the respective cameras to create a simulated bird's eye image. Adjacent ones of the cameras are located at positions and angles so that the peripheral images include a common portion of the ship. The controller performs a calibration process to adjust areas of the peripheral images to be used for the bird's eye image based on a calibration index located at a portion of the ship and included in the common peripheral images.

  • Patent number: 10794708
    Abstract: A server system includes a communicator, a storage, and a controller. The controller is configured or programmed to receive positional information of a watercraft that a user of a wireless communication terminal is aboard and propulsion device information from the wireless communication terminal through the communicator. The propulsion device information indicates a type of a propulsion device on the watercraft. The controller creates cruise trajectory information and stores the created cruise trajectory information in the storage based on the positional information of the watercraft in association with the type of the propulsion device on the watercraft. The controller determines a frequency at which cruise trajectories of the watercraft match the cruise trajectories based on the cruise trajectory information in the storage. The controller creates cruise route information in association with the type of the propulsion device on the watercraft.
