Abstract
A spooling apparatus for use with a well intervention system. The spooling apparatus comprises a pressure vessel capable of being maintained at the same pressure as the well, a flexible line housed in the pressure vessel such that it can be spooled into or out of the pressure vessel, and guidance means directing the flexible line to the outlet. The guidance means is arranged so as to decouple the angle of the flexible line to the outlet from the windings of the flexible line in the pressure vessel. Moreover, the apparatus can be incorporated into wellhead equipment.
