Drilling installation

摘要

A drilling installation for drilling a well, for example an oil, a gas, or a thermal well, includes a tower structure, a first hoisting device adapted to manipulate a first object in a first firing line in the longitudinal direction of the tower structure, a second hoisting device adapted to manipulate a second object in a second firing line in the longitudinal direction of the tower structure, a storage device for vertically storing tubular elements, such as joined tubulars, and a first pipe racker for moving tubular elements between the storage device and the first firing line. The first and second firing line are located outside the tower structure.

1. A drilling installation for drilling a well by means of said installation, which installation comprises:
a tower structure; a first hoisting device adapted to manipulate a first object in a first firing line in the longitudinal direction of the tower structure; a second hoisting device adapted to manipulate a second object in a second firing line in the longitudinal direction of the tower structure; a storage device for vertically storing tubular elements; and a first pipe racker for moving tubular elements between the storage device and the first firing line; wherein the first and second firing lines are located outside the tower structure, and the storage device is located inside the tower structure, wherein the first pipe racker is also configured for moving tubular elements between the storage device and the second firing line, and wherein the first pipe racker is configured to move tubular elements between the storage device and the first or second firing lines via an opening in the tower structure, wherein said opening has a length which is at least equal to a maximum length of a tubular element in the storage device.
