Appl. No.:

13/072233

Inventors:

Bulent Aksel - Houston TX, US
Steven Matthew Wong - Houston TX, US

Assignee:

Vetco Gray Inc. - Houston TX

International Classification:

B63B 21/00

US Classification:

4052244, 4052242, 166355

Abstract:

A push-up tensioner for maintaining a tensile force in a riser having an axis couples to a floating platform and maintains the tensile force while the riser tilts variably from the vertical. The tensioner includes a plurality of cylinders having a lower end pivotally coupled to the deck. The cylinders are substantially perpendicular to the deck in the running position and at an angle to the deck in the tensioning position. After running of the riser, a placement assembly moves the cylinders from the running position to the tensioning position. A tensioner ring is run on the riser proximate to an upper end of the cylinders, and the cylinders are then automatically coupled to the tensioner ring.

Assignee:

Vetco Gray Inc. - Houston TX

International Classification:

E21B 33/038

US Classification:

4052244

Abstract:

A coupler having two degrees of axial freedom couples a hydro-pneumatic cylinder to a tensioner ring of a riser tensioner mounted to a platform. A post extends along an axis of the cylinder and an intermediate sleeve is disposed around the post to form a post annulus. An outer sleeve is secured to the tensioner ring and defines a cavity into which the post and intermediate sleeve are inserted so that an annulus is formed between the sleeve and the outer sleeve. The Outer sleeve is coupled to the intermediate sleeve so that the outer sleeve may pivot on the coupling between the outer sleeve and the intermediate sleeve relative to the intermediate sleeve. The intermediate sleeve is coupled to the post so that the intermediate sleeve may pivot on the coupling between the intermediate sleeve and the post relative to the post.

International Classification:

F16L 37/00
F16L 21/02
F16L 21/00

US Classification:

285323, 285322, 285374

Abstract:

A subsea riser assembly connects two tubular members with axial movement of an outer sleeve. The assembly includes a first tubular member having an end, and a second tubular member having an end with a plurality of box end fingers separated by slots, the second tubular member coaxial with the first tubular member. The end of the first tubular member is inserted into the end of the second tubular member. An outer sleeve having an inner diameter that engages an outer diameter of each box end finger. Axial movement of the outer sleeve relative to the box end fingers causes the inner diameter of the outer sleeve to interact with the outer diameter of the box end fingers, thereby causing the box end fingers to contract radially. The radial contraction of the box end fingers secures the first tubular member to the second tubular member in a made-up position.

Assignee:

Vetco Gray Inc. - Houston TX

International Classification:

E21B 17/01

US Classification:

166355

Abstract:

A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a lower latch ring. After applying tension to the tubular member, the lower latch ring can be closed around the tubular member so that when the tension is released, the upper latch lands on and engages the lower latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.

US Classification:

4052244

Abstract:

A tensioner assembly for applying tension to a tubular member, such as a riser, can include an upper latch connected to the tubular member, a platform with a bore, and a plurality of lower latch segments, each having a base that is pivotally connected to the platform. After applying tension to the tubular member, the segments pivot inward to form an annular lower latch ring having an inner diameter less than an outer diameter of the upper latch. The assembly can include a locking mechanism that prevents axial movement of the upper latch, relative to the lower latch ring, after engagement. The upper latch can self-center on the lower latch as it is moved into the latching position.
