Propellant-Embedded Anchors: Prediction of Holding Capacity in Coral and Rock Seafloors

Abstract

Propellant-embedded anchors have become an important asset in the Navy's mooring equipment inventory. They offer potential for anchoring in coral and rock seafloors where conventional anchors will not work or present logistic problems. Most operational installations of propellant-embedded anchors have been in coral seafloors and these anchors have usually been proof-loaded to their design capacity. The ultimate capacities of these installations have not been determined, hence the full potential of propellant-embedded anchors in coral has not been determined. This report presents the results of a program of model and full-scale propellant-embedded anchor tests in coral and rock. The significance of the results and analysis of the data are presented. A promising equation for predicting holding capacity in coral is developed from the data. It is concluded that the data base of tests in rock is not sufficient for developing an equation for prediction of holding capacity.
