Abstract
A drill assembly for penetrating a wall of a container is provided. The container is supported by a platform within a recovery vessel. The drilling assembly allows removal of a fluid from the container. The drilling assembly includes a tube for lining a first opening into the recovery vessel, as well as a first housing having an interior. A first adapter couples the housing to a first end of the tube to partially define a longitudinal bore. A shaft is rotatably disposed within the longitudinal bore. The shaft has one end for engagement with a drill bit with the other end for engagement with a motor. The drill bit is engaged to the shaft to penetrate the container wall, while the motor is engaged to the other end of the shaft. A first seal assembly forms a first fluid barrier between the interior and the longitudinal bore. Multiple seals may be formed between the first housing and the container. The container and the adapter may be integrally connected. Multiple drilling assemblies may be used and a drilling assembly may be configured to permit the introduction therethrough of a flushing fluid into the container.
