EVALUATION OF A HYDRO-PNEUMATIC FLOATING FENDER OR CAMEL

Abstract

This work is part of an effort to develop a family of camels (floating fenders) which will be lower in combined first cost and maintenance costs than existing fenders and will reduce damage to ship-hulls or to pier fender systems. The performance in Port Hueneme (California) Harbor of a pair of 50-foot-long hydropneumatic camels has been studied over a four-month period. This type of amel employs a floating bulkhead, fronted by two each 40 x 60 in. pneumatic- and hydro-rubber ship-fenders. The hydro-fenders exert their greatest resistance during high-rise time impact loads whilethe pneumatic fenders are capable of absorbing more energy when the impact is of small magnitude and long duration. The rubber cushion units of each camel have a total minimum energy absorbing capacity of 20 foot-tons with a maximum of 86 ft-tons. The capacity depends on the initial air pressure (from 6 to 24 psig) in the pneumatic fenders and the impact characteristics of the ship for the hydro fenders.
