Deployment of cables for landing strings

Abstract

Embodiments may generally take the form of a cable winch system installable within a riser on a landing string. In particular, one embodiment may take the form of a system having a tubular deployable within a riser and a cable winch deployable within a riser. The cable winch is configured to travel with the tubular as it is deployed within the riser.

What is claimed is: 
     
         1 . A system comprising:
 a tubular deployable within a riser; and   a cable winch deployable within a riser, wherein the cable winch is configured to travel with the tubular as it is deployed within the riser.   
     
     
         2 . The system of  claim 1 , wherein the cable spool dispenses cable as it is deployed within the riser. 
     
     
         3 . The system of  claim 2 , wherein the cable is deployed under tension. 
     
     
         4 . The system of  claim 2 , wherein the cable comprises at least one of a fiber optic cable or a copper based cable. 
     
     
         5 . The system of  claim 2 , wherein the cable is terminated at or near a rig floor. 
     
     
         6 . The system of  claim 4 , wherein a flexible jumper communicatively couples the cable with a surface control system. 
     
     
         7 . The system of  claim 4 , wherein a flexible jumper communicatively couples the cable with a subsea control system. 
     
     
         8 . The system of  claim 3 , wherein a hydraulic, electrical or hydroelectrical device provides tension. 
     
     
         9 . The system of  claim 8 , wherein the hydraulic, electrical or hydroelectrical device is configured to compensate for relative motion between a rig at surface and the    
     
     
         10 . The system of  claim 1  further comprising a guide roller assembly installed in a rotary. 
     
     
         11 . The system of  claim 2 , wherein the cable is approximately ⅜″ cable or less. 
     
     
         12 . The system of  claim 2 , wherein the cable is approximately ⅜″ cable or greater. 
     
     
         13 . The system of  claim 1 , wherein the cable winch comprises a level winding system. 
     
     
         14 . A method of providing subsea communications comprising:
 securing a cable winch to a subsea landing string;   securing a cable wound on the cable winch at a surface location; and   deploying the subsea landing string.   
     
     
         15 . The method of  claim 14  further comprising:
 communicatively coupling the cable with subsea controls; and 
 communicatively coupling the cable with a master control system. 
 
     
     
         16 . The method of  claim 15 , wherein a first jumper is coupled between a cable termination and the subsea controls and a second jumper is coupled between a cable termination at surface and the master control system. 
     
     
         17 . The method of  claim 14  further comprising clamping an end of the cable to a landing string tubular after installation to eliminate relative motion between the cable and the landing string. 
     
     
         19 . The method of  claim 14 , further comprising providing tension to the cable as the landing string is deployed. 
     
     
         20 . The method of  claim 14 , further comprising:
 retrieving the landing string; and   winding cable onto the winch.
