Double synthetic sling
A synthetic load transfer assembly. The assembly generally includes a load portion connectable to a connection point (e.g., a shackle) of a load, a first lifting portion connectable to a first lifting device (e.g., a crane of a vessel, a winch of a production system, etc.), and a second lifting portion connectable to a second lifting device (e.g., another crane of the vessel, a crane of another vessel, another winch of the production system, etc.). Load bearing portions connect the load portion to the respective lifting portions. The portions are formed of one or more synthetic materials.
1. A synthetic load transfer sling assembly comprising:
a synthetic first sling including
a first load portion directly connectable to a connection point of a load,
a first lifting portion directly connectable to a first lifting device, and
a first load bearing portion connected between the first load portion and the first lifting portion; and
a synthetic second sling including
a second load portion directly connectable to the connection portion of the load,
a second lifting portion directly connectable to a second lifting device, and
a second load bearing portion connected between the second load portion and the second lifting portion;
wherein the first sling includes a first eye, a second eye, and a leg connected between the first eye and the second eye, the first sling being folded with the first eye and the second eye providing one of the first lifting portion and the first load portion and the leg providing the other of the first lifting portion and the first load portion;
wherein the second sling includes a first eye, a second eye, and a leg connected between the first eye and the second eye, the second sling not being folded with the first eye of the second sling providing the second lifting portion and the second eye of the second sling providing the second load portion; and wherein the first load portion and the second load portion are both centered on the connection point of the load.
2. The assembly of claim 1 , wherein the first sling and the second sling are each formed of a synthetic material including one of an ultra-high molecular weight polyethylene, a recrystallized high modulus polyethylene, a liquid crystal polyester, a gel-spun polyethylene, a para-aramid, a para-aramid copolymer, a polyamide, polyester, or combinations thereof.
3. The assembly of claim 2 , wherein the first sling and the second sling are formed of the same synthetic materials.
4. The assembly of claim 2 , wherein the first sling and the second sling are formed of different synthetic materials.
5. The assembly of claim 1 , wherein at least one of the first sling and the second sling includes a round sling.
6. The assembly of claim 5 , wherein each of the first sling and the second sling includes a round sling.
7. The assembly of claim 1 , wherein at least one of the first sling and the second sling includes an eye-and-eye sling.
8. The assembly of claim 7 , wherein each of the first sling and the second sling includes an eye-and-eye sling.
9. The assembly of claim 1 , wherein the first sling and the second sling are connected.
10. The assembly of claim 9 , further comprising a cover encompassing an associated portion of the load portion of the first sling and of the second sling.
11. The assembly of claim 10 , wherein the cover encompasses at least a portion of the first load bearing portion and of the second load bearing portion.
12. The assembly of claim 9 , further comprising a whipping connecting the first load bearing portion and the second load bearing portion.
13. The assembly of claim 1 , wherein the assembly substantially does not include any metallic material bearing a portion of the load.
14. A synthetic load transfer sling assembly comprising:
a synthetic first sling including
a first load portion directly connectable to a connection point of a load,
a first lifting portion directly connectable to a first lifting device, and
a first load bearing portion connected between the first load portion and the first lifting portion; and
a synthetic second sling including a first eye, a second eye, and a leg connected between the first eye and the second eye, the second sling including
a second load portion directly connectable to the connection portion of the load, the first eye and the second eye of the second sling providing the second load portion,
a second lifting portion directly connectable to a second lifting device, an intermediate portion of the leg providing the second lifting portion, and
a second load bearing portion connected between the second load portion and the second lifting portion;
wherein the first load portion and second load portion are both centered on the connection point of the load, the first eye of the second load portion being on one side of the first load portion and the second eye of the second load portion being on the other side of the first load portion.
15. The assembly of claim 14 , wherein the first sling is folded, and the second sling is not folded.
16. The assembly of claim 14 , wherein the first sling and second sling are both folded.
17. The assembly of claim 16 , wherein the first sling includes a first eye, a second eye, and a leg connected between the first eye and the second eye, the first eye and the second eye of the first sling providing the first load portion, the first eye and the second eye of the first sling being between the first eye and the second eye of the second sling.
