Simultaneous tubular handling system and method
First Claim
1. A system for drilling, said system comprising:
- a drilling deck having a well center;
a primary tubular advancing station configured for advancing a first tubular onto said drilling deck from a substantially horizontal position to a substantially vertical position above said well center;
a stand arm disposed with said drilling deck and configured for handling a second tubular; and
a guided path horizontal to vertical arm positioned adjacent to said stand arm and configured to guide the second tubular onto said drilling deck from a substantially horizontal position to a substantially vertical position adjacent to said stand arm, wherein said guided path arm is configured to guide the second tubular onto said drilling deck during advancing of the first tubular onto said drilling deck to said well center and said guided path arm is configured to operate independently of said primary tubular advancing station.

Abstract
A system and method for building and handling oilfield tubular stands while drilling operations are simultaneously and independently occurring with one drilling deck, one derrick, and one rotary system. An offline guided path horizontal to vertical arm lifts and moves in the same plane tubulars stored horizontally on the catwalk and positions the tubulars vertically directly into a preparation hole for assembling and disassembling tubular stands while online drilling operations are simultaneously being conducted. A stand arm lifts and lowers the tubulars into and out of the adjustable preparation hole, and transports the tubulars for storage to an auxiliary tubular racking station in the upper part of the derrick. A bridge racker crane moves tubular stands from the auxiliary tubular racking station to the top drive or another tubular racking station.

10. A method for moving a plurality of tubulars to a borehole from a drilling deck, said method being performed, at least partially, from a primary tubular advancing station and, at least partially, from an auxiliary tubular handling station, the method comprising the steps of:
-
(a) drilling the borehole through a well center in the drilling deck; (b) moving a first tubular onto said drilling deck with said primary tubular advancing station and to said well center in a first plane comprising said well center; and (c) (i) moving a second tubular onto said drilling deck and in a guided path in a second plane without intersecting said first plane;
(ii) positioning a portion of the second tubular in said second plane on the drilling deck; and
(iii) lifting the second tubular to an auxiliary tubular racking station, wherein step (c) is performed independently of and during at least a portion of the same time as steps (a) and (b). - View Dependent Claims (11, 12, 13, 14)

15. A system for drilling, said system comprising:
-
a drilling deck; a primary tubular advancing station having a well center and configured for advancing a first tubular onto said drilling deck and to said well center; an auxiliary tubular handling station configured for moving a second tubular onto said drilling deck; a stand arm configured for positioning the second tubular in a substantially vertical position; a first tubular racking station above said auxiliary tubular handling station configured for holding the second tubular, wherein the second tubular is moved onto said drilling deck and positioned in a substantially vertical position above said drilling deck and held in said first tubular racking station while the first tubular is advanced onto said drilling deck and to said well center; and a bridge racker crane configured to move the second tubular between said first tubular racking station and said well center, wherein said stand arm is configured to operate independent of said bridge racker crane. - View Dependent Claims (16, 17, 18, 19, 20)
