An inundation prevention system for ship is provided. The inundation prevention system for ship includes a fire-extinction gas ejection part configured to eject a fire extinction gas to an installation area prepared in a hull, an airbag part of 3D shape disposed in the installation area, and an airbag actuation part configured to supply the fire extinction gas to the airbag part, if inundation occurs in the installation are, and to inflate the airbag in the installation for compulsory buoyancy.

System for preventing inundation and ship having the same

By mooring or slowly moving the catamaran in a current through which a garage patch formed of disused plastic particles over than 90% is drifting, a heap of the marine debris flows into the bow of the catamaran and then is smashed. While the disused plastic particles that have been smashed at the bow of the catamaran is moving from the bow toward the stern by way of the tunnel between hulls of the catamaran, the plastic particles are first classified by differences of densities. These first classified plastic particles are collected and then transferred into a narrow and long inside of the catamaran, being finally classified by a triboelectrostatic action. Thereafter, these finally classified plastic particles are made to be pallets which are to be transported to a land facility for recycling or abandoning them.

Low energy consuming garbage patch gathering and classifying equipment and method using catamaran

A radar reflector operating device for indicating an emergency position, capable of permitting a victim to indicate his location by means of a radar reflector even when he is dropped into seawater without a life jacket, easily actuating the radar reflector by pulling or pressing a switch even when low seawater temperature dulls a victim's consciousness and senses of fingers, arms, etc., maintaining an operation of the radar reflector due to safety means even without sustenance of power by a victim that applies power in a predetermined level to operate the radar reflector, allowing an appropriate reflection section and distant recognition by preventing the radar reflector with hydrodynamic wings from being lowered due to wind, etc., and securing a victim, who cannot swim, against dangerous environments by rendering him to use the radar reflector as a life buoy, holding the wings by hands to float on the sea.

A modular RCS (Radar Cross Section) and IR (Infra-Red) signal generation device includes: a plastic bag which is normally stored in a folded state, and inflated when gas is introduced into the bag as desired; a radar reflector received in the plastic bag, the radar reflector being configured in a multi-hedral reflector structure having a reflection characteristic similar to that of a naval vessel to be protected; hot air tubes formed through the plastic bag, hot air being capable of generating IR signals by flowing through the hot air tubes; and connection patches positioned on one of the surfaces of the plastic bag at the points where the ends of the hot air tubes intersect with the surfaces, respectively, the connection patches being adapted to be attached to those of adjacent modular RCS and IR signal generation devices, respectively, so as to interconnect the hot air tubes with those of the adjacent modular RCS and IR signal generation devices.
