Abstract

Abstract Subsea template and method for using the same. A subsea template includes a plurality of gimballed joints for receiving piles therethrough which are anchored in the sea floor. Also included are a plurality of gimballed joints for receiving well conductors therethrough. A template is lowered to the sea floor. The piles and well casings are inserted into their associated gimballed joints from a substantially vertical axis and when finally positioned, are fixedly connected to the gimballed joint associated therewith thus obviating the need for leveling the template.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 83 words
A method for installing a well casing in a formation beneath a body of water comprising the steps of: lowering a template to the floor of the body of water; pivotally coupling a pile to the template; inserting the pile into the formation; pivotally coupling a well casing to the template in a manner which permits well casing movement along the longitudinal axis of the well casing while permitting well casing pivoting in all directions; and inserting the well casing into the formation.
Claim 2
Independent Claim 83 words
A method for installing a well casing in a formation beneath a body of water comprising the steps of: lowering a template to the floor of the body of water; pivotally coupling a pile to the template; inserting the pile into the formation; pivotally coupling a well casing to the template in a manner which permits well casing movement along the longitudinal axis of the well casing while permitting well casing pivoting in all directions; and inserting the well casing into the formation.
Claim 3
Dependent Claim 19 words
The method of claim 1 wherein said method further includes the step of fixing the pile to the template.
Claim 4
Dependent Claim 20 words
The method of claim 1 wherein said method further includes the steps of fixing the well casing to the template.
Claim 5
Dependent Claim 47 words
The method of claim 1 wherein the step of pivotally coupling a pile to the template comprises the step of coupling the pile to the template in a manner which permits pile movement along the longitudinal axis of the pile while permitting pile pivoting in all directions.
Claim 6
Dependent Claim 30 words
The method of claim 4 wherein the step of permitting pile pivoting in all directions comprises the step of permitting pile pivoting in all directions within a predetermined angular range.
Claim 7
Dependent Claim 32 words
The method of claim 1 wherein the step of permitting well casing pivoting in all directions comprises the step of permitting well casing pivoting in all directions within a predetermined angular range.
Claim 8
Dependent Claim 87 words
A template for installing a well casing in a formation beneath a body of water comprising: a frame for resting on the floor of the body of water; means for pivotally coupling a pile to said frame, said pile coupling means permitting pile movement along the longitudinal axis thereof while said pile is so coupled; and means for pivotally coupling a well casing to said frame, said well casing coupling means permitting well casing movement along the longitudinal axis thereof while said well casing is so coupled.
Claim 9
Dependent Claim 87 words
A template for installing a well casing in a formation beneath a body of water comprising: a frame for resting on the floor of the body of water; means for pivotally coupling a pile to said frame, said pile coupling means permitting pile movement along the longitudinal axis thereof while said pile is so coupled; and means for pivotally coupling a well casing to said frame, said well casing coupling means permitting well casing movement along the longitudinal axis thereof while said well casing is so coupled.
Claim 10
Dependent Claim 21 words
The template of claim 7 wherein each of said coupling means is constructed and arranged to permit pivoting in all directions.
Claim 11
Dependent Claim 21 words
The template of claim 8 wherein said template further includes means for fixedly connecting said pile to said pile coupling means.
Claim 12
Dependent Claim 23 words
The template of claim 8 wherein said template further includes means for fixedly connecting said well casing to said well casing coupling means.
Claim 13
Dependent Claim 18 words
The template of claim 8 wherein such pivoting in all direction is limited to a predetermined angular range.
Claim 14
Dependent Claim 176 words
A template for use on a natural floor on a body of water comprising: a substantially planar frame having a pair of passageways therethrough; a first gimballed joint received in one of said passageways, said joint having an opening therethrough for receiving a pile therein, said pile being pivotable in all directions when it is so received; a second gimballed joint received in the other of said passageways, said second joint having an opening therethrough for receiving a well casing therein, said well casing being pivotal in all directions when it is so received; means for fixing said pile to said first joint comprising: an annular groove formed on the radially outer received in said groove, and an annular groove formed on the radially inner sufrace of said second joint opening, sad spring collar being compressible into said well casing groove as said spring collar is lowered into said second joint opening and expanding partially into said opening groove when said collar is adjacent thereto; and means for fixing said well casing to said second joint.
Claim 15
Dependent Claim 176 words
A template for use on a natural floor on a body of water comprising: a substantially planar frame having a pair of passageways therethrough; a first gimballed joint received in one of said passageways, said joint having an opening therethrough for receiving a pile therein, said pile being pivotable in all directions when it is so received; a second gimballed joint received in the other of said passageways, said second joint having an opening therethrough for receiving a well casing therein, said well casing being pivotal in all directions when it is so received; means for fixing said pile to said first joint comprising: an annular groove formed on the radially outer received in said groove, and an annular groove formed on the radially inner sufrace of said second joint opening, sad spring collar being compressible into said well casing groove as said spring collar is lowered into said second joint opening and expanding partially into said opening groove when said collar is adjacent thereto; and means for fixing said well casing to said second joint.
Claim 16
Dependent Claim 41 words
The template of claim 12 wherein said template further includes a funnel mounted on said template about the perimeter of the passageway in which said second joint is received for guiding one end of said well casing toward said second joint.
Claim 17
Dependent Claim 34 words
The template of claim 12 wherein said template further includes a funnel mounted on said second joint about the perimeter of said opening for guiding one end of said well casing into said opening.
Claim 18
Dependent Claim 33 words
The template of claim 12 wherein said template further includes means for limiting gimballed joint pivoting to a predetermined angle from the vertical axis of the passageway in which said joint is received.
Claim 19
Dependent Claim 18 words
The template of claim 12 wherein said template further includes means for laterally shifting said first gimballed joint.
