This is an apparatus for attaching a removable cover to a large vessel. It is adaptable to existing vessels, especially those which have a mounting rim or flange. It uses multiple connector pins which are attached permanently to the vessel and which can be fastened to the cover assembly by a remote operation. It also uses fluid pressure to force the cover against the vessel opening, after which the cover is mechanically secured in place by a second remote operation.

A remotely operable vessel cover positioner in combination with a vessel for remotely connecting and disconnecting a vessel cover to and from the vessel wherein the vessel includes an opening, a mounting rim surrounding the opening and a cover having a perimeter sized to fit against the mounting rim to provide a closure over the vessel opening, comprising; a plurality of connector pins affixed to and extending outwardly from the vessel mounting rim; initial cover positioning means supporting the cover for moving the cover to and from an initial position in which the cover is substantially adjacent to and aligned with the vessel mounting rim; pin connection means having a first portion attached to the cover on a side of the cover opposite from the mounting rim, said first portion having openings therein into which the pins extend when the cover is moved into the inital position, and a second portion which is movable relative to the first portion for interlocking the pins extending into the openings in the first portion with the first portion and thereby locking the cover in the initial position; final positioning means disposed substanatially between the cover and the pin connection means for moving the cover from the initial locked position into a desired final position against the vessel rim and for prestressing the connector pins interlocked with the pin connection means; and final position lock means, disposed substantially adjacent the final positioning means between the cover and the pin connection means, movable relative to the cover from an initial position to a final locking position for locking the cover in the desired final position in which the connector pins are prestressed.
