Abstract
A rotatable chain stopper includes a base, an actuator operatively coupled to the base, and a pair of latches pivotably coupled to the base. The orientation of the base and position of the latches are responsive to extension of the actuator. The rotatable chain stopper may be used as a portion of chain jack assembly, such as on an offshore vessel. The rotatable chain stopper may used in a method of pulling-in, paying-out, and positioning of an anchor chain, such as for mooring an offshore vessel.
