Deployable and Inflatable Fendering Apparatus and Method
Abstract
Fendering systems are used to absorb the kinetic energy of watercraft during berthing operations and to provide a safe minimum standoff distance between moored vessels and other marine structures such as docks, piers, and the like. The principal function of tendering systems is to prevent damage caused by direct contact of the watercraft's hull to other watercraft, docks, piers, and the like. In particular, berthing forces can result in impact and abrasion damage to a watercraft's hull or other marine structures. A deployable and inflatable/deflatable tendering apparatus capable of providing protection for watercrafts and docks is presented. The apparatus has an inflatable cylindrical body, an outer collar body, and a water reservoir with an inflating and deflating means. The collar body circumferentially surrounds the cylindrical body, and is made of abrasion resistant materials and protects the cylindrical body from punctures, tearing and abuse. The collar body may be inflatable or filled with foam-like material. The reservoir comprises a one-way valve, a series of ballasts and is attached to the cylindrical body and is expandable to provide stabilization of the tendering apparatus. The tendering apparatus can be deflated for storage.
