Method of supporting a chain stopper on a vessel, a chain stopper assembly for a vessel, and a vessel

1. A method of supporting a chain stopper on a vessel, the method comprising the steps of:

connecting a swivel element to a rotatable mooring table connected to the vessel such that the swivel element is pivotable relative to the rotatable mooring table around a first axis perpendicular to a substantially horizontal axis; and

coupling a chain stopper element to the swivel element such that the chain stopper element is pivotable relative to the swivel element around the substantially horizontal axis.

2. The method as claimed in claim 1 , further comprising receiving a chain stopper pin in one or more bearings of the swivel element or of the chain stopper element for coupling the chain stopper element to the swivel element and connecting the chain stopper pin at one or more connection points of the chain stopper element.

3. The method as claimed in claim 1 , further comprising receiving a swivel pin in one or more bearings of the swivel element for connecting the swivel element to the rotatable mooring table and connecting the swivel pin at one or more connection points of the rotatable mooring table.

4. The method as claimed in claim 3 , wherein the swivel pin is disposed off-vertically.

5. The method as claimed in claim 3 , wherein the swivel pin is disposed substantially vertically.

6. The method as claimed in claim 5 , further comprising disposing the swivel pin with a shortest distance to a lower connection point on the rotatable mooring table which is smaller than a shortest distance to an upper connection point on the rotatable mooring table.

7. The method as claimed in claim 1 , further comprising feeding a mooring line through a side opening in a hollow main body of the chain stopper element.

8. The method as claimed in claim 7 , comprising choosing a position of the side opening along the hollow main body for reducing lift up of the chain stopper element when a chain is being pulled in.

9. The method as claimed in claim 8 , comprising disposing the side opening nearer to the swivel element than to the distal end of the hollow main body.

10. A chain stopper assembly for a vessel comprising:

a rotatable mooring table for connection to the vessel;

a swivel element connected to the rotatable mooring table such that the swivel element is pivotable relative to the rotatable mooring table around a first axis perpendicular to a substantially horizontal axis; and

a chain stopper element coupled to the swivel element such that the chain stopper element is pivotable relative to the swivel element around the substantially horizontal axis.

11. The assembly as claimed in claim 10 , wherein the swivel element or the chain stopper element comprises one or more bearings for receiving a chain stopper pin for coupling the chain stopper element to the swivel element and wherein the chain stopper element comprises one or more connection points for the chain stopper pin.

12. The assembly as claimed in claim 10 , wherein the swivel element comprises one or more bearings for receiving a swivel pin for connecting the swivel element to the rotatable mooring table and wherein the rotatable mooring table comprises one or more connection points for the swivel pin.

13. The assembly as claimed in claim 12 , wherein the swivel pin is disposed substantially vertically.

14. The assembly as claimed in claim 13 , wherein the swivel pin is disposed with a shortest distance to a lower connection point on the rotatable mooring table which is smaller than a shortest distance to an upper connection point on the rotatable mooring table.

15. The assembly as claimed in claim 10 , further comprising a side opening in a hollow main body of the chain stopper element for feeding a mooring line there through.

16. The assembly as claimed in claim 15 , wherein a position of the side opening along the hollow main body is chosen for reducing lift up of the chain stopper element when a chain is being pulled in.

17. The assembly as claimed in claim 16 , wherein the side opening is disposed nearer to the swivel element than to the distal end of the hollow main body.

18. A vessel comprising:

a rotatable mooring table connected to the vessel;

a swivel element connected to the rotatable mooring table such that the swivel element is pivotable relative to the rotatable mooring table around a first axis perpendicular to a substantially horizontal axis; and

a chain stopper element coupled to the swivel element such that the chain stopper element is pivotable relative to the swivel element around the substantially horizontal axis.
