Abstract

A well intervention system (10) which is adapted to be coupled to a subsea wellhead assembly (12) is described. The subsea wellhead assembly has a wellhead, a subsea tree (14) coupled to the wellhead and a well control package, having a plurality of well control valves, coupled to the subsea tree. The intervention system (10) comprises a vessel (44) for storing and deploying wireline tooling, first fluid communication means extending between the vessel and a purging fluid supply (57) and second fluid communication means extending between the vessel and the well control package at a location above at least one well control valve. In use, purging fluid applied to the vessel via the first fluid communication means displaces fluid from the vessel into the second fluid communication means and into the well control package. Embodiments of the invention are described.
