A pneumatic fender monitoring system is provided. Image data captured by using at least one of a front view imaging device that successively images an external shape in a front view of a pneumatic fender used disposed between a vessel and a vessel or a side view imaging device that successively images the external shape in a side view of the pneumatic fender is successively input into a control unit and successively displayed on a monitor, and the control unit determines, on the basis of the image data, whether an amount of deformation of the external shape of the pneumatic fender is within a preset tolerance range or outside of a preset tolerance range.

A sponson attachment for an airboat allows the airboat to increase its safety and stability very quickly. A method for attaching a sponson to an airboat hull includes attaching first and second flexible tethers to a side of the sponson. The method also includes removably securing the first flexible tether to an exterior of the airboat hull adjacent a gunnel, and removably securing the second flexible tether below the first flexible tether on the exterior of the hull.

Fender arrangement for docking a marine vessel (1) with a boat landing (2) of a marine offshore structure (3) such as a wind power plant, including at least one fender unit (12, 13) composed of elastically deformable material and provided with a receiving recess (18) for a docking rail (5) of said boat landing (2). The fender arrangement is especially characterized in that fender unit (12, 13) exhibits an internal deformation control cavity (20) positioned at a distance from the receiving recess (18) within the fender unit (12, 13) and extending at least along the width of said receiving recess (18), controlling deformation of the fender unit (12, 13) into forming a gripping hold of a docking rail (5) by compression of the internal deformation control cavity (20) when the fender unit (12, 13) is pressed against the docking rail (5).

A plurality of modules are arranged on the broadside of a ship, each module includes a housing, and the housing is provided with a composite gas supply assembly, a composite airbag assembly, an intelligent control assembly, and a mechanical transmission assembly; the intelligent control assembly is configured for predicting the impact energy and a collision angle of a collision object, sending an inflation instruction to the composite gas supply assembly, inflating a large airbag to a proper air pressure, inflating a small airbag to a rated air pressure, and sending an angle adjustment instruction to the mechanical transmission assembly to adjust the collision angle of the small airbag; the large airbag is matched with the small airbag to fully absorb a collision force vertically acting on the surface of a hull.

The present invention relates to a fender comprising a textile envelop surrounding an inflatable chamber, a valve for inflating/deflating said chamber. According to the invention, said textile envelop comprises a central part for receiving said valve and two longitudinal side parts, said side parts being linked together on at least one portion of their length by a junction zone.

In a pneumatic fender, reinforcing layers of a body portion and reinforcing layers of a predetermined range in the longitudinal direction of a fender near a boundary between each hemispherical portion and the body portion are formed by aligning cords of reinforcing layers of the body portion and that of the predetermined range in parallel, and in a neutral state without expansion, the cords of the reinforcing layers of the body portion meet each other and the cords of the reinforcing layers of the predetermined range meet each other, and cord angles A and B are each set to from 15 to 45 with respect to the longitudinal direction of the fender. When the interior of the fender is set to a specified internal pressure, the cord angles A and B increase to extent of a static angle, and the body portion and the predetermined range expand.

An external airbag safety system is provided. The airbag safety system embodied in the present invention is adapted to inflate externally around a vehicle or structure to lessen the impact of a collision. Each external airbag may be urged from a deflated stowed condition to an inflated deployed condition immediately prior the collision sensed by one or more of the sensors. In the stowed condition, the boundaries of the external airbags are mutually inclusive of the boundary of the associated vehicle or structure, while in the deployed condition the inflated airbag forms a shock-absorbing shape protruding operatively beyond the boundary of the associated vehicle or structure, thereby lessening the total destruction wrought from the imminent collision.

Disclosed is a shut-off valve installed in an accommodation chamber regulating entry/exit of air. The shut-off valve includes: a body removably disposed in the accommodation chamber and having multiple air passage holes; a valve stem adapted to be moved vertically along a valve stem insertion hole formed in the body; a disc mounted on a disc engagement portion formed at a lower end of the valve stem to open/close at least one of the multiple air passage holes; a rotor disposed on an upper side of the body to vertically move the valve stem, the rotor being provided with an opening/closing indicator to check opening/closing of the shut-off valve outside the accommodation chamber, wherein the accommodation chamber has an upper wall, a lower wall, and a side wall, the body disposed passing through the upper wall and lower wall of the accommodation chamber, and the disc is located outside the accommodation chamber.

An inflatable boat fender that has an internal DC powered reversible air pump. The reversible pump shall have a battery compartment wherein standard DC batteries can, be placed to power the reversible air pump. The inflatable boat fender can either be cylindrical or tear drop shaped. The air pump can be controlled manually or wirelessly. The air pump shall have an air pressure gauge that will alarm a user when the pressure is below a desired pressure.
