Evaluation of Mk-12 Surface-Supported Diving System (SSDS) Modified Helmet Locking Devices.

Abstract

Modified helmet locking devices to secure the MK-12 SSDS Helmet to the Neck Breech Ring were tested by the Navy Experimental Diving Unit (NEDU) to determine whether a new method could be incorporated into the equipment to prevent the helmet from accidentally separating from the breech ring. Test results demonstrated that a modified arrangement consisting of a new helmet locking device and safety pin will greatly reduce the possibility of the helmet and neck ring accidentally separating. It is recommended that the present MK-12 helmet locking device be replaced as an interim measure, with the modified configuration. For a permanent solution to the problem, a helmet locking device similar to that used on the MK-11 Dry Hat should be investigated. (Author)
