The influence of padeye offset on plate anchor re-embedding behaviour

Abstract

Equations that can be used to predict the trajectory of a plate anchor under pull-out load are derived from a simple combined loading yield surface assuming associated flow. They are used to directly predict the behaviour of plate anchors with different padeye offsets and under loads of varying inclinations. It is demonstrated that there is an optimal padeye offset that depends on the load inclination and causes the anchor to increase its embedment, and hence its capacity, under pull-out. The equations represent an elegant and efficient method to assist in the design of plate anchors, notably in optimising the padeye location.
