EXPLOSIVE ANCHORS FOR SHIP MOORING

A 50,000-pound nominal capacity (XM-50) explosive embedment anchor and a 200,000-pound nominal capacity (XM-200) explosive embedment anchor have been designed and tested by the Army for application in ship mooring. Tests include determinations of anchor penetration, ultimate holding capacity, and short-term creep in most sub-bottom sediments except rock. Full-scale mooring tests of a T-5 tanker and a Navy LST ship have been successfully accomplished. Test results have been incorporated in optimizing the anchor's physical configuration and installing procedure. It is concluded that the two sizes of explosive anchors offer installing and operational advantages for ship mooring compared to conventional fluked anchors. Testing to date indicates that the explosive anchors will perform satisfactorily for ship mooring provided that they are properly installed.
