Pipe Handling Equipment

Abstract

System for handling pipes on a drilling deck, comprising a pipe-handler ( 20 ) that is rotary around a vertical axis, a storage device ( 1 ) which in turn comprises an opening ( 14 ) through which pipes can be retrieved and inserted, and an intermediate storage ( 14 ) in connection to the opening. The storage ( 14 ) having the function of a lock gate dividing the drill floor into two separate pipe handling areas. The pipe-handler ( 20 ) is arranged to reach both the intermediate storage ( 14 ) in connection to the opening and the drilling centre ( 15 ). The storage device ( 1 ) comprises a pipe transport device which in turn comprises a gripper ( 30 ) that is arranged to grip at least one pipe from above and transport the pipe hanging from the gripper ( 30 ) between a storage position and the opening ( 14 ). The storage device ( 1 ) is surrounded by a closure ( 13 ) that prevents pipes from unintentionally getting outside the storage device ( 1 ).

1 . Device for storing pipes comprising at least one upper and one lower finger board, characterized in that the device is arranged on the drill floor and is surrounded by a closure ( 13 ) that defines a storage area ( 1 ) and prevents pipes from unintentionally falling outside the storage area ( 1 ), and having a defined opening for feeding pipes into the storage area and for retrieving pipes form the storage area ( 1 ), the opening having a lock chamber ( 14 ) being adapted to hold one or more pipes, and the lock chamber dividing the drill floor into two separate pipe handling areas. 
   
   
       2 . Device according to  claim 1 , characterized in that the lock chamber is an intermediate storage ( 14 ) where a number of pipes can be placed temporarily whilst waiting to be brought out of the storage area ( 1 ) or to be fed into the storage area ( 1 ). 
   
   
       3 . Device according to  claims 1 , characterized in that it comprises a further temporary storage next to the opening. 
   
   
       4 . Device for lifting pipes, characterised in that it comprises a gripper that is arranged to grip at least one pipe from above and transport this suspended inside a storage area to and from an opening in the storage area. 
   
   
       5 . Device for storing drill collars and other special pipes, characterized in that it comprises a pipe stand ( 23 ) which is arched with the centre of the circle sector co-inciding with the rotation centre of a rotary pipe-handler, such that the pipe-handler can reach the drill collars and the special pipes at the same distance from the centre of rotation and the pipe slots in the pipe stand ( 23 ) is only defined by an angular distance between the pipes. 
   
   
       6 . Device for transporting pipes to and from a drilling centre, characterized in that it comprises a gripping head that is arranged to grip the pipe at its upper end and further comprises a device to rotate the pipe around its own axis, to be able to screw pipes off and on the upper end of another pipe. 
   
   
       7 . System for handling pipes on a drilling deck, characterized in that it comprises a pipe-handler that is rotary about a vertical axis, a storage device which in turn comprises an opening through which pipes can be retrieved and inserted and an intermediate storage in connection with the opening, as the pipe-handler is arranged to reach both the intermediate storage and the drilling centre. 
   
   
       8 . System according to  claim 7 , characterized in that it further comprises a mouse hole device for building up pipe stands, said mouse hole device comprising several chambers to receive pipes and that the pipe-handler is arranged to reach the mouse hole device. 
   
   
       9 . System according to  claims 7 , characterized in that the storage device comprises a pipe transporting means which in turn comprises a gripper that is arranged to grip at least one pipe from above and transport the pipe hanging from the gripper between a storage position and the opening of the pipe storage. 
   
   
       10 . System according to  claims 7 , characterized in that the storage device is surrounded by a closure that prevents pipes from unintentionally getting outside the storage device. 
   
   
       11 . Device according to  claims 2 , characterized in that it comprises a further temporary storage next to the opening. 
   
   
       12 . System according to  claims 8 , characterized in that the storage device comprises a pipe transporting means which in turn comprises a gripper that is arranged to grip at least one pipe from above and transport the pipe hanging from the gripper between a storage position and the opening of the pipe storage. 
   
   
       13 . System according to  claims 8 , characterized in that the storage device is surrounded by a closure that prevents pipes from unintentionally getting outside the storage device. 
   
   
       14 . System according to  claims 9 , characterized in that the storage device is surrounded by a closure that prevents pipes from unintentionally getting outside the storage device.
