Soft yoke mooring arrangement
Aspects of the disclosure pertain to single point mooring systems and method used in relation to single point mooring systems wherein, the system divides the restoring weight for the mooring system in two and removes hinges and swivel joints from the gravitational load path suspending the restoring weight.
1. An arrangement, comprising:
at least one mooring support structure configured to be attached to a floating structure;
at least one first connection connected to the mooring support structure;
a first ballast weight connected to the at least one first bearing;
a second ballast weight connected to the at least one first bearing;
at least one second connection connected to the first ballast weight and the second ballast weight;
at least one yoke connected to the at least one second connection;
at least one third connection connected to the yoke; and
at least one fourth connection connected to the at least one third connection.
2. The arrangement according to claim 1 , wherein the at least one mooring support structure is two mooring support structures.
3. The arrangement according to claim 1 , further comprising:
pendular tension members located between the mooring support structure and the first and second ballast weight, wherein the tension members are configured to withstand both tension and bending.
4. The arrangement according to claim 3 , wherein the first, second, third and fourth connections are part of a load path between one of the yoke and first and second ballast weights and the pendular tension members.
5. The arrangement according to claim 1 , wherein the arrangement is configured to be disconnected and reconnected from the floating structure.
6. The arrangement according to claim 5 , wherein the disconnection and reconnection occur between the yoke and pendular tension members.
7. The arrangement according to claim 6 , wherein the disconnection and reconnection occur at the at least one second connection.
8. The arrangement according to claim 1 , wherein the at least one second connection allows rotation around three axes.
9. The arrangement according to claim 1 , wherein the at least one first connection allows rotation around two axes.
10. The arrangement according to claim 1 , wherein the at least one third connection allows rotation around two axes.
11. The arrangement according to claim 1 , wherein the at least one fourth connection allows rotation around one axis.
12. The arrangement according to claim 1 , wherein the first and the second ballast weight are located below a surface level of water.
13. The arrangement according to claim 1 , further comprising:
at least one pin, located between the floating structure and the mooring support structure, the at least one pin configured to connect and disconnect the floating structure to the mooring structure.
