An analytical solution method capable of determining the geometric configuration and developed tensile forces of mooring lines associated with fixed plate/pile or drag anchors embedded in cohesive seafloor has been developed. The solution method is capable of analyzing multisegmented mooring lines embedded in layered cohesive seafloor soils, utilizing a systematic iterative solution search method based on specified boundary conditions. The results of the developed analytical solution method have been verified through comparisons with the centrifuge model tests and field tests and were found to be very effective.
