Abstract: The anchoring mechanism comprises a guide post lock formed in the shape of a sleeve. The sleeve is movable inside a guide post and can lock the guide post to a funnel of a seabed frame by means of lower lockpins passing through radial bores in the guide post. The guide post lock can be raised by an anchor lock for a wire. Raising the anchor lock enables the lockpins to be moved radially inwards. The anchor lock is also able to raise the guide post by upper lockpins in axial slots in the guide post lock passing through upper, radial bores in the guide post. The lower lockpins are pressed inwardly by means of the lower beveled edge of the funnel.
