Abstract:
A method for removal of a top drive device in a wellbore drilling installation, e.g. for servicing and/or exchanging a top drive device. The frame of the trolley and the top drive device are provided with cooperating vertical guide members so that the top drive device is vertically displaceable and guided relative to the frame. The top drive device has an operative position above the rotatable head clamp assembly carrier, which is releasably connected to first and second vertical frame members. In order to service and/or exchange of the top drive device, the method includes releasing the rotatable head clamp assembly carrier from the first and second frame members, removing the rotatable head clamp assembly carrier, lowering the top drive device relative to the frame of the trolley until the cooperating vertical guide members thereof disengage, moving the lowered and disengaged top drive device to a service and/or storage location remote from the firing line.

Claim (Index 41):
The method according to  claim 33 , wherein said top frame member is provided with connectors, here holes, for connecting thereto a series of cable sheaves in a side by side arrangement, and wherein the drilling tower is provided with a crown block having cable sheaves so that the trolley is suspended by one or more winch driven cables in a multiple fall arrangement.
