Abstract: Provided are a system and method for supporting a return home mode of a drone used on a ship. A drone control device receives GPS reception signal strength information at a first GPS receiver, drone takeoff feasibility information is displayed on a display unit of the drone control device if the GPS reception signal strength is greater than or equal to a set strength, a drone drive motor is controlled by generating a drone drive motor control signal based on ship position information received from the drone control device and drone position information received from a second GPS receiver when a control unit installed in the drone receives return home information from the drone control device after the drone takes off, and the control unit stops the drone drive motor when the difference between the drone position and the ship position is less than or equal to a set distance.

Abstract: Disclosed is an apparatus and method for estimating tidal fronts. The method for estimating tidal fronts includes obtaining past observation data of a sea area to be estimated, substituting and calculating the obtained past observation data into a preset whole water depth mixing discriminant for a plurality of points in the sea area to be estimated, and as a result of the calculation, regarding an area of points where a calculated value is less than or equal to a preset reference value as a whole water depth mixing sea area, regarding an area of points where the calculated value exceeds the preset reference value as a stratified sea area, and estimating a boundary between the regarded whole water depth mixing sea area and stratified sea area as a tidal front.

Abstract: Proposed is a system and method for simulations of marine pollution dispersion using a numerical tracer technique, wherein modeling is faster than conventional diffusion modeling methods by reducing computational volume and load and thereby a simulation of marine pollution dispersion with respect to the long-term continuous discharge may be performed through the numerical tracer technique by configuring to simulate the marine dispersion of suspended sediments (SS) and COD using the Quick Dispersion (Q-DISP) model, which is a diffusion model using the Monte Carlo method, in order to solve the problems of conventional marine pollution dispersion modeling systems and methods using numerical tracer techniques which have the disadvantage of requiring a high-performance computer and a large amount of memory due to the increased computation.

Abstract: A cold pool detection method and system is proposed. The cold pool detection method is characterized by including collecting and generating sea surface temperature data in a target area, partitioning the target area and generating partitioned areas, setting up clusters of each partitioned area, and sorting out cold pool candidate groups and detecting a cold pool. Here, the setting up of the clusters of each partitioned area is characterized by including setting clustering values for setting the clusters of each partitioned area, and setting the number of the clusters of each partitioned area. The cold pool detection method and system is capable of partitioning a target area, clustering partitioned areas to establish clusters, and using a standard deviation to determine a cold pool.

Abstract: An upright tank-based propulsion assistance rotor sail system is proposed. The system may include an upright tank fixed to a hull of a ship, and a rotor sail in a form of a cylindrical shape having a length and diameter greater than or equal to the upright tank, and installed to surround part or all of an outer circumferential surface of the upright tank. The rotor sail may be rotatably installed while surrounding the upright tank concentrically with the upright tank, and may be movable along a height direction of the outer circumferential surface of the upright tank depending on situations to maintain a predetermined height. In addition, a vessel equipped with the upright tank-based propulsion assistance rotor sail system is proposed, The fuel tank may be installed to stand upright on the vessel so that the rotor sail is installed to be movable in the vertical direction.
