anchor holding capacity

A simple method of selecting the right anchor for mooring

Feb 15, 2020 · For the anchor to be adequate for holding this vessel in the given environment, the anchors holding power F HOLD must be greater than the environmental force, i.e., F HOLD > F ENV . The anchors holding power, FHOLD depends on the the type of anchor, the size of the anchors fluke and also on the seabed type.


The vertical anchor capacity is based upon the working capacity of ASTM A-36 rod stock anchor bolts in 2500 psi concrete or grout. To fully develop this capacity, anchor bolts must be properly lapped with the piers vertical reinforcement. The capacity is based on fc = 2500 psi; Fy = 36,000 psi.
