Multi-operational multi-drilling system
First Claim
1. A system comprising:
- a setback and racking system having a center axis;
a first set of wellbay accesses positioned along a wellbay access perimeter that surrounds the center axis, wherein each of the first set of wellbay accesses is associated with a wellbay substantially therebelow, and wherein at least a portion of the setback and racking system is positioned at an elevation lower than the elevation of the wellbay accesses;
a drilling module coupled to a skidding system that is positioned at a level higher than the setback and racking system, wherein the skidding system is operable to rotate the drilling module about the center axis so as to selectively position the drilling module in alignment with each of the first set of wellbay accesses, and wherein the setback and racking system is configured to feed tubulars to the drilling module when the drilling module is in alignment with each of the first set of wellbay accesses.

Abstract
A system including a setback and racking system and a set of wellbay accesses, at least a portion of the setback and racking system positioned at an elevation lower than the elevation of the wellbay accesses. A system including a centrally located setback and racking system, a set of wellbay accesses, and at least one peripheral skidding system, wherein the setback and racking system is positioned at least partially below the elevation of the peripheral skidding system. A system including at least one peripheral skidding system and a set of wellbay accesses positioned along a wellbay access perimeter surrounding a central focus that is not an integral part of the peripheral skidding system. A method of drilling by aligning each of at least two drilling modules with a respective wellbay access via a peripheral skidding system and operating at least two drilling modules at least partially simultaneously.

21. A system comprising:
-
a centrally located setback and racking system; a set of wellbay accesses positioned substantially equidistantly apart from each other along a wellbay access perimeter, each of the plurality of wellbay accesses associated with a wellbay substantially therebelow; at least one peripheral skidding system located on a main deck of a drilling platform, wherein the at least one peripheral skidding system is operable to position a plurality of drilling modules with a plurality of the wellbay accesses, wherein the centrally located setback and racking system is positioned at least partially below the elevation of the peripheral skidding system, and wherein the centrally located setback and racking system is configured for rotational movement about its center of axis to feed tubulars in substantially the direction of each of the plurality of wellbay accesses. - View Dependent Claims (22, 23, 24, 25, 26)

27. A method of drilling, the method comprising:
-
aligning each of at least two drilling modules with a respective wellbay access via a peripheral skidding system operable to position a plurality of drilling modules proximate a plurality of wellbay accesses, wherein the plurality of wellbay accesses is aligned in a wellbay access perimeter and wherein each wellbay access is associated with a wellbay substantially therebelow; and operating the first of the at least two drilling modules to perform a first operation and the second of the at least two drilling modules to perform a second operation, wherein at least a portion of the first and second operations are performed simultaneously, and wherein the wellbay access perimeter at least substantially surrounds a central setback and racking system that is configured to feed tubulars to each of the at least two drilling modules. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
