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 (10) comprising a retainer arm (30), having a control line retainer thereon, is driven between a removed position with the retainer arm (30) positioned adjacent to a base and adjacent to a rig floor and a raised position with the retainer arm (30) raised by a drive member to a raised position to hold one or more control lines (90) along a portion of the length of a pipe string (80) to facilitate application of a clamp to secure the control lines to the pipe string (80). In one embodiment, the retainer arm (30) may be releasably secured to a docking assembly (50) 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 (112) comprising a plurality of rolling members to direct one or more control lines to a retainer assembly.
