Abstract

A replaceable subsea filter uses a hot-stab style connection. The filter has a flow path located along a central axis. At a distal end of the of the filter, the flow path locates inside a subsea receptable, typically associated with a reservoir or sea chest for a hydraulic actuator. At a proximal end, the flow path opens into an annulus around the stab-connecter, the annulus being separated from the surrounding waters by annular filters.
