Abstract: A wellhead assembly includes a containment system having a mechanical barrier, a tertiary wiper, and a fluid jet assembly. A mechanical barrier includes a body disposed in a housing, the body having an opening extending through an axial thickness of the body. A tertiary wiper has an elastomeric body with a hole extending centrally therethrough. A fluid jet assembly includes a jet assembly body having a wall defining a cavity extending axially through the jet assembly body and an array of nozzles positioned circumferentially around the wall, wherein each nozzle has an outlet directed in a radially inward direction from the wall toward a central region in the cavity. The components of the containment system are arranged an axially stacked arrangement relative to each other.
