Embodiments of the present invention provide systems and methods for using nonwoven materials for evacuation slides, life rafts, life vests, and other life-saving inflatable devices. The nonwoven materials have a substrate layer with continuous filaments formed in various directions.

A portable marine anchoring device maximizes holding capacity while anchored into the ground. The device is fabricated from lightweight aluminum.

In a membrane type heat insulation system for a cryogenic liquefied gas carrier cargo tank and a liquefied gas fuel container, a secondary heat insulation layer comprises a plurality of panels which are stacked in multiple layers while each pair of upper and lower panels is arranged to intersect each other, whereby heat loss which may occur in the gap between the panels can be minimized and deformation due to a temperature difference can be minimized.

The present invention provides an eco-friendly underwater buoy and a manufacturing method therefor, the underwater buoy comprising: a liner main body of which the inside is hollow; a winding member which is melt welded on the outer surface of the liner main body by winding, and which absorbs external shock; and buoy couplers embedded in both ends of the liner main body so as to couple adjacent underwater buoys to each other. The present invention winds, through filament winding, a wire, in which a glass fiber, a resin and the like are mixed, around the outside of a liner structure so as to manufacture an underwater buoy, and thus, since the underwater buoy is made of a composite material, the appearance of the buoy structure can be stably maintained for a long time without damage caused by various underwater shocks, so that underwater environmental pollution caused by buoy structure damage can be minimized, thereby maximizing the eco-friendliness of the underwater buoy.

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.

An elastic structure anti-impact frame body for use in ships, automobiles, aircraft, trains, railcars and other moving vehicles, said frame body being a wholly or partially elastic frame, the bearing components constituting the frame body forming an arc-shape or a wave-shaped curve, and the frame body being made of an elastic material. The whole or part of the structure of the elastic structure anti-impact frame body has an elastic deformation function; on the premise that the elastic structure does not affect normal driving or bearing capacity, under the force of an impact on said frame, the frame body will elastically deform within a corresponding safe range, and can cushion and absorb the energy of the impact; the frame body, when releasing the energy of the impact, returns to the original shape, greatly improving the anti-impact security factor.

A fiberglass pontoon boat, having raised and integrated fiberglass side rails, a flat floor, and a side entry level with the flat floor. Integrated seats are molded in fiberglass. The hull and deck join together by flexing the hull to compensate for opposing draft angles of the hull and deck at the side entry. The deck has a floor and at least one other interior component, and terminates in a deck trim flange. The hull has at least two hollow pontoons and at least two side rails that extend from an outer edge of the pontoons, and the hull terminates in a hull trim flange. When assembled, the hull trim flange operatively engages beneath the deck trim flange to form a unified pontoon boat having a space between the deck and hull and wherein the side rails are integrated as structural parts of the interior component.

A modular catamaran is a small body catamaran capable of being easily disassembled. The catamaran has approximate dimensions of ten feet-four inches (10′-4″) long and ninety-five and a half inches (95½″) wide having a pair of foam filled fiberglass pontoons. The top of the catamaran is fabricated with a welded aluminum frame that may be provided complete with seats and an engine.

A portable marine anchoring device maximizes holding capacity while anchored into the ground. The device is fabricated from lightweight aluminum.

A system for mounting equipment to a vessel's hull is disclosed. The system comprises a first stringer and a second stringer, where each stringer is attachable to the inside of the vessel's hull. The system also includes a layer of adhesive attaching both stringers to the inside of the vessels hull. Both stringers have a top cap for attaching equipment. Additionally, each stringer has a first vertical side wall connected to a first end of the top cap, a second vertical side wall connected to a second end of the top cap, and two flanged portions. A first flanged portion connects to a lower end of the first vertical side wall, and a second flanged portion connects to a lower end of the second vertical side wall. The system has an open side portion at the bottom end of both stringers.
