The present invention provides an auxiliary berthing method and system for a vessel. In the berthing method, by a solar blind ultraviolet imaging method, a position and an attitude of a vessel relative to a shoreline of a port berth during berthing are calculated by at least two solar blind ultraviolet imaging modules according to light signals received by a solar blind ultraviolet light source array arranged in advance on the shore. Further, when more than three solar blind ultraviolet imaging modules are used, in the method and device of the present invention, a normalized correlation algorithm and a data fusion algorithm are used to improve the accuracy of the position and attitude data of the vessel.

Artificial-intelligence-based river information system. In an embodiment, a first training dataset is used to train a travel time prediction model to predict a travel time along the waterway for a given trip. In addition, a second training dataset is used to train a river level prediction model to predict a river level along the waterway for a given time. For each of a plurality of trips, a request is received that specifies the trip and a time of the trip, and, in response to the request, the travel time prediction model is used to predict a travel time for the trip, and the river level prediction model is used to predict a river level of the waterway at one or more points along the trip. Then, a voyage plan is generated based on one or both of the predicted travel time and the predicted river level.

A navigation information device is provided with a position acquisition unit for acquiring a position information of its own ship, a memory for storing display settings corresponding to a waypoint that is a via point on a planned route, and a display processing unit for performing generation processing for generating a screen in which the position information is superimposed on a chart, and performing change processing for changing display settings to display settings corresponding to the waypoint based on a positional relationship between the position information and the waypoint.

The purpose is to provide an image generating device which generates a synthesized image from which one is able to intuitively grasp a relation between an image and a traveling position of a water-surface movable body. The image generating device includes processing circuitry. The processing circuitry acquires attitude information indicative of an attitude of a camera or a ship where the camera is installed. The processing circuitry acquires a traveling route of the ship based on a detection result of at least one of a position and a direction of the ship. The processing circuitry generates traveling route display data based on the attitude information and the traveling route. The processing circuitry generates a synthesized image in which the traveling route display data is synthesized with an image outputted from the camera.

A Very Large Bag (VLB) suitable for containing and transporting various liquids is disclosed that includes solar arrays to generate electric power.

Such features include navigational and positioning devices, powered by solar arrays that include perovskite materials with efficiencies that exceed silicon based solar arrays. Aspects of embodiments of the present invention further include features useful for purifying or preserving the purity of the fluid being transported.

A water surface system for mitigation of tropical storms or hurricanes/typhoons/cyclones, the water surface system comprising one or more floating objects capable of minimizing water temperature increase due to sun irradiation and water evaporation and one or more boom-like structures capable of containing the floating objects in a designated area. For effective mitigation, the designated areas are the origins and paths historically most often occurred of storms/hurricanes/typhoons/cyclones.

Systems and methods for conveniently providing anchoring assistance onboard a watercraft are provided herein. An example system includes a display and a processor in communication with a marine system. The processor is configured to receive marine data from the marine system and/or one or more user inputs and cause the display to show one or more anchoring locations with visual indications of the anchorage quality index based on at least the marine data and/or user inputs. The one or more anchoring locations may be shown as a heat map overlaid on a map. The system may use real-time marine data, environmental data, weather data, tide data, etc. to dynamically adjust the anchoring locations and anchorage quality index. The system may enable convenient and helpful suggestions and notifications to the user when anchoring a watercraft. Some examples provide automatic deployment of an anchoring system and monitoring of a current anchoring.

A watercraft steering system includes a reverse reduction transmission and an obstacle detector. The reverse reduction transmission is configured to convert power from a main engine into an output for causing a watercraft to make forward travel, neutral, or reverse travel, so as to control navigation of the watercraft. The obstacle detector is disposed at a hull of the watercraft and is configured to detect an obstacle. The watercraft steering system is configured to, based on a location of the obstacle with respect to the hull, a travel direction of the watercraft, a travel speed of the watercraft, and a distance between the hull and the obstacle, select from among the forward travel, the neutral, and the reverse travel, and maintain the travel speed or change the travel speed.

A non-transitory computer-readable recording medium stores therein a generation program that causes a computer to execute a process. The process includes acquiring positional information including positions of a plurality of ships at a plurality of timings; acquiring, or generating from the positional information of the plurality of ships, sailing route information; and generating closest distance information for each sea area corresponding to positions of closest approach of two ships, from the positional information and the sailing route information, the closest distance information including a statistical quantity of a distance of closest approach between the two ships, the statistical quantity of a distance of closest approach being calculated based on encountering relationship for directions of the two ships and whether or not ship tracks of the two ships are along a sailing route in the sea area.
