The present invention relates to a maritime distress signal transmission device which transmits a distress signal to an arbitrary rescue station to rescue a person in distress by transmitting a distress signal of the person in distress at sea wearing a life jacket and precise location information based on the Global Positioning System (GPS) to the rescue station as audible sound, and the maritime distress signal transmission device includes a holder-cradle which is coupled to the life jacket of the person in distress by a clip and a main body which is coupled to the holder-cradle and transmits the rescue signal to an arbitrary receiver using a preset frequency band.

The present disclosure provides a ship monitoring system capable of improving legibility of an OZT. The ship monitoring system includes a first data generator, a second data generator, and processing circuitry. The first data generator generates first ship data indicative of a position and a velocity of a first ship. The second data generator generates second ship data indicative of a position and a velocity of a second ship. The processing circuitry calculates a risk value indicative of a risk of a collision between the first ship and the second ship based on the first ship data and the second ship data, for each point on an estimated course of the second ship, when the first ship is assumed to change a course and reach the point. The processing circuitry specifies a range where two or more continuous points have the risk values above a threshold. The processing circuitry displays a risk range including the range where the two or more continuous points have the risk values above the threshold.

A ship monitoring system has a first data generator that generates first ship data indicative of a position and a velocity of a first ship. The second data generator generates second ship data indicative of a position and a velocity of a second ship. The processing circuitry specifies a risk range where a ship area occupied by the first ship or a watch area set around the first ship overlaps with a ship area occupied by the second ship or a watch area set around the second ship, among an estimated course of the second ship, based on a position of the first ship and a position of the second ship at each timing, that are estimated from the first ship data and the second ship data, when assuming that the first ship changes a course to an arbitrary direction and crosses the estimated course of the second ship.

A Ship Movement-Sharing Navigation Support System is provided based on IoT or AI by using inexpensive and easy-to-carry user terminals such as smartphones or tablets. A method for navigating a ship comprises receiving a position information transmitted from a user terminal used in a user terminal-equipped ship via a mobile telephone network; receiving a position information via an AIS system transmitted via a VHF radio from an AIS device-equipped ship; and displaying icons of the user terminal-equipped ship and the AIS device-equipped ship on a nautical chart or radar display of the user terminal. In addition, the method comprises calculating a predicted moving route of the user terminal-equipped ship and the AIS device-equipped ship based on the information received from the user terminal and the AIS device and preventing a collision by displaying a caution or warning alert in a case there is a possibility of collision.

A method, system, and apparatus for collecting waste. In one embodiment, an autonomous plastic collecting robot (APCR) device for collecting waste may include a net structure that picks up micro plastic particles dispersed in water; a tube that transports the micro plastics collected by the net structure into a main internal container; an artificial tongue for collecting larger plastics, the artificial tongue comprised of a rolling staircase with fork-like structures in placed of the stairs; a plastic degrading medium contained in the main internal container; a no-joint tail structure which acts as the primary power source for the APCR, the no-joint tail structure housing dielectric elastomer materials and a rotation shaft located between at least two electric generators.

A hull cleaning system is disclosed that comprises a below-waterline hull cleaning head arranged to clean an underwater portion of a hull in-situ, a location determining system arranged to produce location information indicative of the location of the hull cleaning head relative to the hull, and a hub facility remotely located relative to the hull cleaning head. The hub facility is arranged to store the location information, and the system is arranged to send the location information to the hub facility for storage at the hub facility so as to thereby provide a record at the hub facility of clean portions of the hull that have been cleaned by the hull cleaning head and fouled portions of the hull that have not yet been cleaned by the hull cleaning head. The system is also arranged to provide on-line access to the location information stored at the hub facility so as to thereby enable cleaning to continue at a subsequent time using the stored location information.
