Abstract
A temporary hub cover for the hubs of flow lines, hydraulic lines, and electrical conduits and the mating hubs of the underwater production unit includes a body enclosing the hub, plungers within the body for releasably engaging into detents on the hub to hold the cover on the hub, and a trigger mechanism operable from a remote location to release the engagement between the cover and hub whereby the cover can be removed from the hub. A connector tool is lowered through the water and supports means for operating the trigger mechanism upon downward movement of the connector tool.
