Abstract
An impact- and tension-resistant control line suitable for attachment to an underwater oil or gas flow line, for attachment to a downhole tubing string or for control in subsea workover operations. The control line protector includes a resilient elongated body, any number of hydraulic tubes, electrical and electronic lines within the body and at least two impact-resistant, tensional-bearing members such as wire ropes within the body. When viewed in cross-section, the wire ropes are disposed within the body so that the protected control lines lie between the two wire ropes and a planar force or impact from any direction cannot directly contact the protected control lines. Additional impact-resistant, load-bearing members can be disposed among the protected control lines to insure that a planar force cannot directly contact the protected control lines while the device is attached to a flow line.
