Abstract
An operational package comprising either a pump/driver package (1; 100) or a valve package (250) is retrievably installed at a subsea station by a receptacle (10; 110; 251). Co-operating connection means on the package and the receptacle establish fluid and/or electrical connection between the package and the receptacle on reception of the package within the receptacle. Seal means (14) carried by the package are moved into a condition to seal any such fluid connections. Installation is effected by establishing a running loop extending from a surface vessel downwardly through the receptacle (10; 110) and upwardly to the surface vessel outside the receptacle, the package (1; 100) being moved on and guided by the wire loop from the surface vessel into the receptacle. Alternatively, a handling tool (120) is employed with co-operating releasable connecting means (151) on the handling tool and the receptacle, and operating means (124, 125) operable between the handling tool and the package to effect movement of the package inwardly of the receptacle, after connection of the connecting means.
