Abstract:
A method for servicing a top drive device of a wellbore drilling installation. The installation comprises a drilling tower, a drill floor having a well center through which a drilling tubulars string can pass along a firing line. A trolley is guided along a vertical trolley rail. A top drive device is attached to the trolley and comprises one or more top drive. A motion arm assembly comprises a base and an extensible and retractable motion arm, wherein the base is guided by a vertical motion arm rail. The motion arm has an operative reach that encompasses the firing line. The motion arm assembly is adapted to support at least one of a well center tool, e.g. an iron roughneck tool and a tubular gripper member, and allowing to bring said well center tool or tubular gripper member in the firing line. In order to remove a top drive motor from the top drive device whilst the rest of the top drive device remains attached to the trolley, the motion arm assembly and/or the trolley are operated so that the top drive motor is within the operative reach of the motion arm, the motion arm is operated to reach the top drive motor and the top drive motor is connected to the motion arm, and then the motion arm is used to support and/or lift, lower said top drive motor upon disconnection thereof from the rest of the top drive device.

Claim (Index 18):
The combination of  claim 15 , wherein the top drive device is mounted within the frame so as to be vertically mobile relative to the frame by one or more vertical displacement actuators, wherein said one or more vertical displacement actuators are adapted to perform a controlled lowering and raising of the top drive device during a make up or a breaking of the threaded connection between the quill or rotary stem on the one hand and the tool joint of the tubular suspended from the rotatable head clamp assembly on the other hand.
