PARAVANE ROLL STABILIZATION
The United States Navy is developing new vessels which will spend a large percentage of their time at low or zero speed and ship stabilization is required to permit the crew to function effectively. Paravane stabilizers are an inexpensive and effective method for low speed ship stabilization. Because these devices had been used only on small vessels, and because there were no existing numerical design methods, the Navy undertook a program which consisted of a theoretical study, development of a design methodology, and practical application to two intermediate size of ships (170 tons and 1000 tons) leading to the final application to a 2000 ton ship. The first use of the methodology to design an experimental rig for the 170 ton vessel is given. The conclusions drawn from the test of this vessel are presented. Briefly, the methodology works and reductions of rms roll amplitude of more than 60 percent can be easily achieved. Although much work remains to be done before we have a complete understanding of the action of paravanes or a truly complete design method, the present rudimentary method produces satisfactory stabilizing systems.
