METHOD AND APPARATUS TO POSITION AND PROTECT CONTROL LINES BEING COUPLED TO A PIPE STRING ON A RIG

摘要

A control line positioning apparatus comprising a retainer arm having a control line retainer thereon, is driven between a removed position with the retainer arm positioned adjacent to a base and adjacent to a rig floor and a raised position with the retainer arm raised by a drive member to a raised position to hold one or more control lines along a portion of the length of a pipe string to facilitate application of a clamp to secure the control lines to the pipe string. In one embodiment, the retainer arm may be releasably secured to a docking assembly disposed adjacent to the pipe engaging apparatus and adjacent to a rig floor. In one embodiment, the control line positioning apparatus may comprise an ascending control line pathway comprising a plurality of rolling members to direct one or more control lines to a retainer assembly.
