Abstract
Apparatus for compensating ship motion for sea-state conditions in order to protect oceanographic instrumentation which would normally be subjected to loss due to high shock loads in the instrumentation cable by which it is supported. The apparatus utilizes large power springs attached to a compensator cable and sheave through which the instrumentation cable is reeved. The spring reduces the suspension frequency of the instrumentation cable below the ship excitation frequency so that the motion from the ship can be isolated from the instrumentation cable. These springs may be in the form of spirally-wound flat strips of high-tensile alloy which, when wound, exert a torque to the compensator cable reel such that the tension on the instrumentation cable can be maintained fairly uniform.
