A remotely operable vessel cover assembly used with a vessel. The cover assembly has a mounting rim secured to the vessel surrounding a circular opening and a circular cover to fit against the mounting rim. A force ring having a plurality of openings is attached to the cover. Connector pins are attached to and extend from the mounting rim and through a plurality of holes in the cover and the force ring. A lock ring is rotatably attached to the force ring and locks the extending heads of the connector pins to the force ring to restrain the cover in an initial position.

Coking vessel unheading device and support structure

An unheading device for removable attachment onto a lower flanged opening of a vertically-oriented vessel such as a coking drum, the unheading device being controllably supported by multiple elongated vertically-extendable actuators such as hydraulic cylinders which extend between a lifting frame unit holding a head unit and the vessel support structure. The multiple vertically-extendable actuators are each pivotably attached at its lower end to the lifting frame unit, and are each pivotably attached at its upper end to the separate stationary support structure for the vessel. The unheading device is adapted for lowering the head unit and moving it laterally aside to a parking position on a platform portion of the vessel support structure, then raising the lifting frame unit with its attached decoking chute unit to contact the vessel lower flanged opening for coke removal therefrom. After such coke removal step, the decoking chute can be lowered and the head unit returned laterally to a position below the vessel, and then lifted by the multiple actuators and reconnected onto the vessel lower flange.

This system employs a containment shield that safely permits drainage through the bottom head and contains water and coke avalanches.

Stud tensioning device for flange cover

A mechanism for selectively securing a cover to a flange of a pressure vessel. A plurality of such devices can be employed, using a plurality of studs that extend through matching openings in the flange and cover. A movable anchor plate or plates, also with holes through which each stud extends, is disposed adjacent to the flange or cover. The head of each stud will fit through its associated hole of the anchor plate (and into the opening of the closer one of the flange or cover) only if the anchor plate is properly oriented. When the anchor plate is so oriented, a piston head at the opposite end of the stud can be actuated away from the flange and cover to retract the stud head into the opening of the flange or cover. This protects the stud when the cover is disengaged from the flange. The stud can be biased in the opposite direction to permit the anchor plate to be reoriented into a position in which the stud head cannot pass through the anchor plate, so the stud can clamp the flange and cover together.
