Wellsite hose and conductor payout and retraction method and system

Abstract

A reel system allows for storage, paying out, and retrieval of conductors, such as high pressure hydraulic hose, electrical conductors, or any other length of reeled conductor. For well operations, hydraulic control hose may be filled or dry for storage. Pigtail ends of the hose pass through an aperture of a core of a reel into an umbilical space. The hose may be payed out as needed at the job or well site, and the pigtail ends then removed from the umbilical space for connection to a source of pressurized fluid. The reel may be immobilized from rotation during this stage. Once the onsite operations are complete, a drive system may be powered to cause rotation of the reel to retrieve and restore the hose. Multiple hoses may be stored on the reel, and multiple reels may be mounted and independently driven on a common support of the system.
