Abstract
A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure.
Claims24
A restraint system for use in securing temporary flowlines that include multiple pipe sections, each pair of sections connected together with one or more fittings, the system comprising:
- a) an assembly of multiple endless loop slings connected end-to-end, each said sling having first and second sling end portions, said sling end portion secured to one or more of said other slings with a knotted connection;
- b) a plurality of disconnectable fittings that each join one assembly of multiple slings to another assembly of multiple slings;
- c) wherein the disconnectable fitting is not a said sling;
- d) the slings attached to the assembly of pipe sections and fittings with knots at spaced apart positions;
- and
- e) each knot formed by a portion of a said sling that encircles the temporary flowline at a position in between said first and second sling end portions.
A method for restraining a temporary flow line that includes multiple pipe sections, each pair of sections connected together with a disconnectable coupling to form a pipe assembly, comprising the steps of:
- a) providing first and second sling assemblies, each assembly comprising multiple endless sling loops connected to one another, each said sling having first and second sling ends;
- b) each sling assembly including at least three endless loop slings connected end to end, one of the endless loop slings being a middle sling that connects at spaced apart positions to the other said slings;
- c) the endless loop slings connected end to end connecting each plurality to another plurality with a disconnectable connector;
- d) the slings attached to the assembly of pipe sections and fittings with knots;
- and
- e) wherein each knot is formed by a portion of a said sling in between said first and second sling ends that encircles the flow line.
A method for restraining a temporary flow line that includes multiple pipe sections, each pair of sections connected together with a disconnectable coupling, comprising the steps of:
- a) providing multiple connected endless loop slings, each endless loop sling having first and second sling ends;
- b) one or more of the endless loop slings connecting to another said sling with a disconnectable connector;
- c) knotting the slings to the flow line at intervals with spaced apart knots;
- and
- d) wherein each knot is formed by a portion of a said sling in between said first and second sling ends that encircles the flowline.
