Handling device for an installable and retrievable subsea apparatus

A handling device for an installable and retrievable subsea apparatus, the subsea apparatus in a releasable manner to engage an apparatus mating ISO standardized docking device on a subsea installation, the apparatus mating ISO standardized docking device having a pair of outwardly extending engagement members having an aperture and an engagement rim, the handling device comprising:

• wherein handling device is configured as a yoke which is provided with a top member and a pair of engagement arms depending therefrom to extend along an outside face of the retrievable subsea apparatus;
• wherein each of the arms at a free end thereof is provided with a hook configured to engage in a releasable manner a rim on the apparatus mating ISO standardized docking device;
• wherein a rotary handle is located above the top member and has an integral or linked stem which extends through the top member and is pivotally linked to a top region of the retrievable subsea apparatus;
• wherein the handle and its stem in a first rotary position are movable transversely of the top member between set limits, but are rotationally locked relative a main body of the retrievable subsea apparatus hanging freely from the stem;
• wherein the handle and its stem are locked and prevented from any movement relative to the top member when in a second rotary position with the handle closest to the top member and with the arm hooks in engagement with the docking device rims, and thereby locking docking engagement between the retrievable subsea apparatus and the apparatus mating ISO standardized docking device;
• and
• wherein a rear side of the hooks is inclined to gradually engage a lower inclined region of the retrievable subsea apparatus and upon its movement into the apparatus mating ISO standardized docking device to cause the hooks to be pressed into and held in engagement with the docking device rims.
