Abstract: Device for storing tubular on a drilling and/or production installation, comprising a shaft (8, 9, 10, 11) to accommodate a plurality of tubular in a substantially vertical position and a guide (15, 22) that is moveable above the shaft (8, 9, 10, 11). The device comprises means for displacing the guide (15, 22) in a substantially horizontal plane to a position above a selected one of all the tubular in the shaft. Also described are a catwalk (12) configured to displace the tubular in an axial direction through a V-door in the derrick (5), and which is further configured to be tilted into a substantially vertical position to receive or deliver a tubular, and a knuckle boom crane (7) with a grapple (27) that is adapted to grip an upper end of a substantially vertical tubular and carry the tubular in a substantially vertical orientation.

Abstract: An apparatus for storing tubulars on a floating semi-submersible drilling or production vessel. The apparatus comprises a storage device for storing tubulars in a submerged position, essentially below a splash zone. The storage device is generally open to the surroundings so that the tubulars are externally exposed to surrounding water. It is also described an apparatus for transporting tubulars between a storage and a derrick on an offshore drilling and/or production platform having a platform deck. The apparatus is situated below the platform deck and is adapted for movement under the platform deck. A method for disassembling a pipe string is also described.
