VESSEL THAT INCLUDES DRILLING RIG AND METHOD OF WELL DRILLING USING PLANT Russian patent published in 2017 - IPC B63B35/44 E21B7/128 

FIELD: oil and gas industry.

SUBSTANCE: vessel includes the drilling rig for well drilling. The plant comprises a drill floor surrounding an axial line of the well bore, a first tower pylon located on the vessel deck and containing a rod structure with two elongated hollow bodies, which extend parallel to longitudinal axis of the rod structure and are rigidly connected to each other by connecting elements. The core structure is mounted on the side of the drill floor so that the longitudinal axis of the core structure runs parallel to the centerline of the well bore and so that the longitudinal axis and the centerline of the well bore are substantially centered with each other in the core structure width direction. The additional support of the tower pylon is located between the vessel deck and the position of the upper location on the first tower pylon. Two storage devices for storing the drill pipes in a vertical position, two pipe feeders and stackers, each pipe feeder and stacker are connected to one of the two storage devices, and each pipe feeder and stacker is configured to move the drill pipes between the associated storage device and the centerline of the well bore. Two storage devices are installed on opposite sides of the drill floor so, the storage devices and the drill floor are centered with each other in the direction of the rod structure thickness, each body of the rod structure of the first tower pylon carries one of two devices for the two pipe feeder and stacker devices.

EFFECT: increase the efficiency of the drilling rig located on the vessel.
