Abstract : The development of a method for the prediction of drag anchor holding capacity in soft cohesive soils is described. This method is unique in that it: separates treatment of the anchor and the embedded mooring chain, accounts for the soil cutting resistance mobilized by the embedded chain, and incorporates the undrained soil shear strength in determining anchor and chain contributions. The method is applicable for several anchor types with (in-air) weights up to 50 kips. The method incorporates several chart-type design aids. An example drag anchor system design is included, along with a brief discussion of factors of safety appropriate for use with this new method.
