ABSTRACT:
The system for deploying cable having nodes according to the present invention includes a tubular member, first and second restrictors, and a controller. The cable having nodes travels through the tubular member from a cable supply point to a deployed point. The deployed point is a fluid medium at a higher pressure than the cable supply point. The first and second restrictor form part of the tubular member with the second restrictor being disposed closer to the deployed point. The first and second restrictor have at least a first and second operating position. In the first operating position the restrictors allow the cable to pass, and in the second operating position the restrictors allow both the cable and the nodes to pass. Depending on their operating state, the first and second restrictor restrict the flow of the fluid medium through the tubular member. The controller controls whether the first and second restrictor are in the first and second operating position. The first and second restrictor may, for example, be multi-port blowout preventers.
