Abstract:
An arrangement of fenders nested together for compact storage, the fenders including two or more cylindrical bodies having a cavity accessed through the fender top, the fenders being similar shape but graduated in size such that the cavity of a larger fender tensionally receives the next smaller sized fender, the outer diameter of the smaller fender equal to the inner diameter of the larger fender cavity. A fender has a rigid inner core surrounded by a compressible shell made of foam or similar material. The inner core has attachment points for a rope or line. The smallest nesting fender in the set has a cavity diameter sized to fit a commercially-available, off-the-shelf fender. The fenders may be separated and deployed at individual locations on a vessel, or kept together and deployed as a single fender capable of absorbing a greater impact than any of the fenders individually would absorb.

Abstract:
Dampers for mounting on a dock to control landing a boat. The dampers may be used individually or in damper systems made up of a plurality of dampers. Each damper has a flexible body with one or more sidewalls defining an inner chambers, and orifices are provided in one of the sidewalls to allow the chamber to be filled with water when the damper is in an at-rest state. When the boat approaches the dock and contacts the damper or the outer set of dampers in a damper assembly/system, the collision or impact force applied by the boat against the outer surfaces of the damper(s) causes the damper body to be compressed, which causes the sidewalls of the chamber to collapse so as to expel water out of the inner chamber via the orifices so as to reduce the speed of the boat at a desired rate of deceleration.
Abstract:
A modular inflatable protection system for protecting an item is provided. The system includes a plurality of inflatable modules, each of the modules having an inflatable body; a gas valve configured to receive a gas to inflate the inflatable body; a first connection portion; and a second connection portion. The first connection portion is configured to removably connect a first one of the modules to the second connection portion of a second one of the modules, the first connection portion can be reused to connect the first one of the modules to the second connection portion of a third one of the modules, and the system is configured to provide a barrier to protect the item from damaging contact by a potentially damaging element.
Abstract:
A pneumatic fender and a mouth piece metal for a pneumatic fender with an open/close valve fixed at a position in which a through hole formed in a dividing wall constituting a receiving chamber, where the valve is closed by closed position fixing members. A safety valve is isolated from a cavity of a fender bladder by a receiving chamber, the safety valve being able to be detached and attached while the pneumatic fender is in use. A confirmation test of a valve opening pressure of the safety valve is performed by opening a receiving chamber open/close valve and raising an internal pressure of a cavity of the receiving chamber to a pressure threshold via a receiving chamber communication passage. The open/close valve is fixed at a position in which the through hole is open by open position fixing member.
Abstract:
This invention relates to a new marine fender, and relates to a method of assembly a fender. The fender is comprised of four quadrant sections that are conjoined at mating surfaces with tapered wedges inserted into tapered mortises formed at interrelated surfaces. This method of assembly enables an articulated cam action joint which dynamically interacts with kinetic impact energy. Preferably, the components are made from resilient material that is suitable for compression molding, and are approved for use in the marine environment. One preferred embodiment of the invention encircles a single piling. The fender can be positioned to float with changing water levels, and rotate upon impact. The marine fender can be installed on existing isolated and independent marine structures, such as monopiles and dolphins, with little or no modification of the structure.
Abstract:
A fastening device including a first tube defining a first major axis, a distal portion, a proximal portion, and a through hole, the proximal portion of the first tube including an attachment element. A second tube is disposed within the through hole of the first tube, the second tube defining a second major axis that is substantially orthogonal to the first major axis. The attachment means may be one or more notches, a flange, a socket, a wedge and a clamp, or an arm. The first tube may have a bend, and the bend may be between approximately 25° and approximately 30°. Further, the second tube may define a second tube length, and may include a first component and a second component that screw together to provide an adjustable second tube length. The first tube and second tube may be pivotally coupled.
Abstract:
An apparatus for inhibiting damage from impact between a marine structure and an adjacent watercraft, and a related method, are described. The apparatus includes a cushion body forming a mounting surface and a watercraft-engaging surface substantially opposing the mounting surface, at least one rigid support member, the rigid support member defined by or configured for contact with the mounting surface of the cushion body and disposed, during use, between the cushion body and the portion of the marine structure, and attachment means for detachably attaching the cushion body to the portion of the marine structure. The cushion body, when attached to the portion of the marine structure, is sized and configured to prevent destructive contact between the marine structure and a watercraft when the watercraft-engaging surface is contacted by the watercraft.
Abstract:
The present technology provides a system for detecting the tensile force of a guy rope in a pneumatic fender capable of preventing the breakage of the guy rope, and a pneumatic fender. Tensile force data detected by a tensile force sensor detecting the tensile force of a guy rope is transmitted by a wireless transmitter, and is inputted to a computation device through a receiver. An alerting device issues an alert when the tensile data is at least equivalent to reference data previously inputted to the computation device.
Abstract:
An impact relieving device includes an impact portion and a fixed portion. The impact relieving device has an integral structure that is formed by one-step extrusion molding. The impact portion includes an inner layer and an outer layer. The inner layer and the outer layer are separated by a separation rib to form a cavity. The outer layer of the impact portion is arc-shaped, and an arc surface protrudes outwards. The impact relieving device has low manufacturing cost, is easy to manufacture and install, has a simple structure, and can effectively relieve an impact force.
