Abstract
There is disclosed a marine vessel which is particularly suited for mine hunting operations or the like because of improved survivability characteristics in the presence of multi-directed underwater transmitted excessive shock or vibration forces, such as are generated by a nearby exploding mine or the like. The ship is of the propeller driven type having a propeller shaft driving engine and gearbox unit mounted inboard of the vessel hull upon a rigid sled-like platform which in turn is resiliently supported relative to rigid structure of the vessel by spring means sandwiched therebetween. The spring means are of such nature as to resiliently yield in response to excessive compression, tension, shear or roll forces encountered from any direction. The spring means comprises an array of spaced apart spring devices, and back-up blocks of non-resilient compression-deformable material are provided in association therewith.
