Abstract
A drill assembly (44) for penetrating a wall (85) of a container (14) is provided. The container (14) is supported by a platform (30) within a recovery vessel (12). The drilling assembly (44) allows removal of a fluid from the container (14). The drilling assembly (44) includes a tube (88) for lining a first opening (42) into the recovery vessel (12), as well as a first housing (90) having an interior (80). A first adapter (94) couples the housing (90) to a first end (89) of the tube (88) to partially define a longitudinal bore (82). A shaft (102) is rotatably disposed within the longitudinal bore (82). The shaft (102) has one end for engagement with a drill bit (84) with the other end for engagement with a motor (46). The drill bit (84) is engaged to the shaft (102) to penetrate the container wall (85 ), while the motor (46) is engaged to the other end of the shaft (102). A first seal assembly (98) forms a first fluid barrier between the interior (80) and the longitudinal bore (82).
