Restraint System For Tight Flowline Configurations, And Method of Use Thereof

Abstract

A restraint net is provided for use in restraining a tight grouping of flowline elements where restraint lines are unusable. The restraint net includes a net body woven of one or more restraining ropes; and a net perimeter comprising one or more restraining ropes, surrounding the net body. The restraint net is configured to cover the tight grouping of flowline elements and being of sufficient tensile strength to restraint movement of the flowline elements in case of a failure or separation of the flowline elements in the tight grouping. A method is also provided of restraining a tight grouping of flowline elements where restraint lines are unusable. The method includes: providing the restraint net as described above; coupling a first point of the net perimeter to any one or more of an anchoring device, an adjacent restraint net or an adjacent restraint line; extending the net body over the tight grouping of flowline elements; and securing one or more further points of the net perimeter to one or more further anchoring devices, one or more further restraint nets, or one or more further adjacent restraint lines. Upon a failure or separation of the flowline elements, the restraining net restrains movement of the flowline elements.
