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 a temporary flowline that includes multiple pipe sections, each pair of sections connected together with one or more fittings, the system comprising:
- a) an assembly of multiple flexible restraining slings connected end-to-end, one sling having end portions, a said end portion secured to one or more of said other slings;
- 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;
- and
- d) the slings attached to the assembly of pipe sections and fittings with knots at spaced apart positions, each knot encircling the temporary flowline.

A restraint system for use in securing temporary flowlines that include multiple pipe sections, each pair of sections connected together with fittings, the system comprising:
- a) multiple slings connected end-to-end, one sling having an end portion that is secured to one or more other slings with a knot;
- b) disconnectable fittings that join one said assembly of multiple slings to another assembly of multiple slings;
- c) wherein the disconnectable fitting is not a said endless loop sling;
- and
- d) attaching the assemblies to the flowlines at intervals using a combination of knotted connectors that each encircle the flowline.
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 slings, at least one said sling including a loop portion;
- b) each plurality including at least three endless loop slings connected end to end with each sling attached to another said sling with a knot;
- c) the slings connected end to end, one sling assembly connecting to another sling assembly with a disconnectable connector;
- and
- d) knotting the slings to the flow line at intervals with knots that each encircle the temporary flow line.
23-25. (canceled)
A restraint system for use in securing a temporary flowline that includes multiple pipe sections connected together with fittings comprising:
- a) an elongated flexible restraining member;
- b) the elongated flexible restraining member connecting to the temporary flowline with multiple knots that each encircle the temporary flowline;
- and
- c) wherein the elongated flexible member abuts the temporary flowline in between knots.
