DRAG EMBEDMENT ANCHOR PERFORMANCE PREDICTION IN SOFT SOILS
A rational approach to calculating the drag embedment performance of marine anchors in cohesive soils is presented. The method considers the geotechnical and gravity/buoyancy forces acting on all components of the anchor system including various areas on the anchor and the attached mooring line which may be either chain or wire. The solution proceeds in a piece-wise linear manner until an equilibrium position is found for the anchor. This anchor burial depth, the anchor drag distance, and an anchor angle of rotation in the soil. The equilibrium position may be such that the anchor holds the applied line load and no further movement occurs, or it may be such that the anchor can dig no deeper and horizontal movement is predicted with a given maximum resistance. The solution technique requires a computer program. Such a program has been developed and the results from the program have been compared with large scale tests performed in the Gulf of Mexico in 1990.
