Abstract

A purge system for use with a well intervention system and apparatus is disclosed. The purge system permits well fluids contained in a subsea intervention system to be purged prior to retrieval of the intervention system to the surface. The system comprises a vessel (44) for storing and deploying wireline tooling, the vessel being exposed to well fluids via the well control package (16) and first fluid communication means (58) connected between a purging fluid supply and the well control package, and second fluid communication means (60) connected between the vessel and the well control package wherein, in use, the purging fluid supply to the vessel via the first fluid communication means displaces fluid from the vessel into a second fluid communication means and into the well control package.
