  • Patent number: 10287862
    Abstract: A containment apparatus for protecting a surrounding environment from leaks originating from a stuffing box is provided. In some embodiments, the containment apparatus utilizes a float switch to switch off a pump associated with the stuffing box when the level of a liquid in the vessel exceeds a predetermined level. The switch can communicate ultrasonically with a receiver that relays a message to a user. In some embodiments, the vessel comprises two half vessels that are lined by a metal frame along their mating edges.

  • Patent number: 9920586
    Abstract: An apparatus for containing leaks from a stuffing box on a wellhead production assembly, the apparatus comprises a containment vessel consisting of two half shells that are joined below the stuffing box. Additionally, the apparatus comprises a transparent lid having an upper opening to receive a polished rod extending from the stuffing box. The lid is secured to the containment vessel in a liquid tight manner such that the stuffing box is substantially isolated from the environment so that any leaks originating from the stuffing box will be contained in the apparatus.

  • Patent number: 9151428
    Abstract: An injection-molded load line connection spillage container for catching and retaining liquid spilled when liquids are pumped between storage tanks and tankers provides an injection-molded reservoir and an injection-molded cover attached to the reservoir by hinges. Reinforcing ribs molded into the reservoir provide strength and ruggedness without the need for reinforcing steel collars and saddles. Gussets molded into the reservoir hinge brackets ensure repeated stresses produced by energetic opening of the cover does not result in failure of the hinge brackets. An optional load line mounting assembly permits secure mounting of the load line container directly onto the load line. An optional cleanout assembly provides a valved suction line for removing retained spillage, and an optional sampling assembly provides a valved sample line for sampling the liquid being transferred.

    Abstract: An apparatus for containing leaks from a stuffing box on a wellhead production assembly is provided. The apparatus comprises a containment vessel consisting of two half shells that are joined below the stuffing box. The apparatus further comprises a seal subassembly. The components of the seal subassembly are positioned one the nipple and pumping tee below the stuffing box. The half shells are positioned about and joined to the seal subassembly in a manner that provides a liquid tight seal. Additionally, the apparatus comprises a transparent topper having an upper opening to receive a polished rod extending from the stuffing box. The topper is secured to the containment vessel in a liquid tight manner such that the stuffing box is substantially isolated from the environment. As such, any leaks originating from the stuffing box will be contained in the apparatus.
