Abstract

Loops may be installed on a high pressure flow line and/or well service flow line to reduce movement of components of the flow line in the event of a rupture and/or substantial dislocation of at least a portion of the flow line. At least one restraining link having at least one flexible loop extends across at least one swivel assembly and is secured to adjoining pipes of the flow line. The at least one restraining link is secured while the swivel assembly is in an angled position. A length of the at least one restraining link is less than a horizontal length of the at least one swivel assembly while in an in-line position, preventing, or substantially preventing, the swivel assembly from moving to, or substantially towards, the in-line position. Also, at least one flexible anchor support tether may be wrapped around a coupling between tubular components of the flow line so as to create a right connection loop and a left connection loop. Right and left anchor tethers are looped through the connection loops. Opposite end portions of the anchor tethers are connected to well site equipment and/or other suitable securing sites.
