A method for determining a displacement of an anchor is provided. The method includes the steps of: determining an initial position of the anchor; and determining a displacement of the anchor. The step of determining the displacement of the anchor includes (i) measuring anchor velocity values, (ii) measuring at least one further physical quantity associated with the anchoring, (iii) deciding whether the anchor is at rest or in motion, wherein a value of the further physical quantity is taken into account in the decision, and (iv) integrating the velocity values over time during intervals when the anchor is deemed to be in motion.
