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.
