Abstract
A spool for deploying and retrieving multiple separate strings of continuous tubing, such as over the side of or through the moon pool of a boat, rig or other vessel, without the need of an injector head. The spool has at least one rotating swivel to permit pumping of fluid(s) down, or back up, tubing strings while the spool is rotating or stationary. A level-wind assembly having at least one sheave directs the continuous tubing overboard, but also level-winds the tubing onto the spool in an orderly fashion through lateral movement of the sheave. The system is powered by a hydraulic power unit with a remote control console.
