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.
Claims19
A rotatable chain stopper assembly comprising:
- a base;
- latches coupled to the base;
- and
- latch adapters coupled with the latches, wherein the latches are sized to grip a first chain size, wherein the latch adapters are sized to grip a second chain size, and wherein the second chain size is smaller than the first chain size.
A rotatable chain stopper assembly comprising:
- a base;
- latches coupled to the base;
- and
- latch adapters coupled with the latches;
- wherein the latch adapters, coupled with the latches, are pivotable between an open position and a closed position.
A rotatable chain stopper assembly comprising:
- a base;
- latches coupled to the base;
- and
- latch adapters selectively attachable and detachable with the latches
- wherein the latches are sized to grip a first chain size, wherein the latch adapters are sized to grip a second chain size, and wherein the second chain size is smaller than the first chain size.
A method of positioning an anchor chain, the method comprising:
- providing a chain jack assembly comprising a chain jack and a rotatable chain stopper, the rotatable chain stopper comprising a base and latches coupled to the base;
- pulling-in, paying-out, or combinations thereof a mooring line using the chain jack, the mooring line comprising an anchor chain coupled with a messenger chain;
- attaching latch adapters to the latches;
- positioning the latch adapters to grip a link of the messenger chain;
- and
- gripping the link of the messenger chain with the latch adapters attached to the latches.
