Abstract: A portable pipe storage device (1) for use in a drilling rig (10), the pipe storage device (1) including a frame structure (2) with long sides (4) and end portions (6, 8) and the pipe storage device (1) being arranged to hold two or more pipes (14), pipes (14) stored in the pipe storage device (1) having their longitudinal axes (16) in a standing direction when the pipe storage device (1) is in its position of use in the drilling rig (10).

Abstract: A gripper for petroleum pipes, the gripper including a housing and two gripper arms. The gripper arms are provided, at end portions, with gripping surfaces and are pivotable, at opposite end portions, around respective first axes. Each of the gripper arms is connected to the housing by respective first pivotal links, each of the first pivotal links being pivotably connected to the respective gripper arm around a second axis which is between the gripping surface and the first axis. Each of the first pivotal links is pivotably connected to the housing around a third axis, and each of the gripper arms is connected to the housing by a respective second pivotal link around the first axis. Each of the second pivotal links is pivotably connected to the housing on respective fourth axis fixed relative to the housing, the two first pivotal links being independently pivotable.

Abstract: A device for an electromechanical hoisting machine (10) with driving gears (6) in engagement with rack rails (5) fixed to a steel structure (1). The hoisting machine is driven by electromotors (8) which transmit torque to the driving gears (6) through the gearing (11), the shaft (15) and further the bevel gear drives (14, 16, 17) and gears (18, 19) to the driving gears (6) in engagement with rack rails (5). To achieve flexible load distribution on the driving gears (6), differential gears (12) supported on projecting shaft journals (20) connected to the main shaft (15) are arranged between the bevel gear drives (16).

Abstract: A method for intervention in an underwater production well, in which the well head (1) of the production well is located on the seabed (2), and wherein a drilling rig (26), which comprises at least a robotized drill floor (32), is placed at the well head (1), after which necessary intervention operations are carried out in a remote-controlled manner by means of the drilling rig (26).

Abstract: A drilling placed on the seabed and arranged for drilling of oil and gas wells is remote controlled from a light drilling vessel (2) through pipes and signal cables (3). The main structure of the drilling rig is made up of two cylindrical structures (1 and 10), in connection with which there is provided a number of cylindrical silos (8) for storing drill pipe magazines (23). A complete drilling module (17) can be lowered and retrieved through hatchways (11) at the top of the first cylindrical structure 10 The drilling rig is anchored to a foundation frame (7) by hydraulic legs (9).

Abstract: A drilling rig device (1) situated on the seabed (11), where the drilling rig (1) is sealingly enclosed against the surroundings, wherein the drilling rig (1) is liquid-filled and provided with a separator (16) arranged to separate material (17) from the liquid.
