Abstract
A high pressure flow line that is formed from sections of pipe that are coupled together is provided with a safety restraint assembly. The safety restraint assembly is formed by wrapping short, flexible rib tethers around the pipeline near the ends of each section of pipe. A plurality of long tethers are linked end-to-end to form a continuous spine, which is threaded through all of the rib tethers. Each of the tethers contains continuous filaments. The spine is then anchored at each of its terminal ends to suitable anchoring structures. Alternatively, the safety restraint assembly may utilize anchor elements in addition to the tethers.
