Cable spools with sheaves

A reel assembly for accepting, holding, and deploying cable, hose or umbilical connections, comprising:

• a spool assembly including a frame and a drum mounted in said frame, the drum including a core and end flanges for storing said cable, hose or umbilical connection;
• an air motor;
• a sheave coupled to one or more sensors that determine either a force applied to the sheave, a length of cable, hose or umbilical connection deployed, or both;
• an electro-pneumatic drive unit including a plurality of pneumatic valves, electro-pneumatic valves, or both, the air motor coupled to the drum via the electro-pneumatic drive unit;
• a local electronic control unit coupled to the electro-pneumatic drive unit and the one or more sensors, where the local electronic control unit receives user input and transmits electrical signals to the electro-pneumatic drive unit to cause the electro-pneumatic drive unit to control the motor to rotate the drum;
• and
• a remote electronic control unit coupled to the electro-pneumatic drive unit and the one or more sensors, where the remote electronic control unit receives user input and transmits electrical signals to the electro-pneumatic drive unit to cause the electro-pneumatic drive unit to control the motor to rotate the drum.

A system for deploying a blow out prevention (BOP) stack, the system comprising:

• a plurality of reel assemblies for accepting, holding, and deploying cable, hose or umbilical connections or the like, each assembly comprising:
• a spool assembly including a frame and a drum mounted in said frame, the drum including a core and end flanges for storing said cable, hose or umbilical connection,
• an air motor,
• a sheave coupled to one or more sensors that determine either a force applied to the sheave, a length of cable, hose or umbilical connection deployed, or both;
• an electro-pneumatic drive unit including a plurality of pneumatic valves, electro-pneumatic valves, or both, the air motor coupled to the drum via the electro-pneumatic drive unit, and
• a local electronic control unit coupled to the electro-pneumatic drive unit and the one or more sensors, where the local electronic control unit receives user input and transmits electrical signals to the electro-pneumatic drive unit to cause the electro-pneumatic drive unit to control the motor to rotate the drum;
• and
• a remote electronic control unit coupled to the electro-pneumatic drive unit of each of the plurality of reel assemblies and the one or more sensors of each of the plurality of reel assemblies, where the remote electronic control provides user interface controls for controlling each of the plurality of reel assemblies, receives user input for controlling a selected reel assembly and, in response, transmits electrical signals to the electro-pneumatic drive units of the selected reel assembly to cause the electro-pneumatic drive unit of the selected reel assembly to control the motor of the selected reel assembly to rotate the drum of the selected reel assembly.
