Abstract

A lifting elevator includes a first elevator segment having a first plurality of slips, a second elevator segment having a second plurality of slips, and a hinge. The first elevator segment and the second elevator segment each have a swept angle of about 180°, and each of the first plurality of slips and the second plurality of slips includes a die configured to grip an external surface of a pipe.

Claims (38)

1. A lifting elevator, comprising:

a first elevator segment having a first plurality of slips;

a second elevator segment having a second plurality of slips;

a hinge about which both the first elevator segment and the second elevator segment are rotatable with respect to each other,

wherein the first elevator segment and the second elevator segment each comprise a swept angle of about 180°;

a first lifting lug directly coupled to the first elevator segment;

a second lifting lug directly coupled to the second elevator segment,

wherein the first lifting lug and the second lifting lug are configured to carry a load of a conductor string that includes the joint of pipe;

wherein each of the first plurality of slips and the second plurality of slips comprises a die configured to grip an external surface of a pipe;

a segmented timing ring coupled to the first plurality of slips and the second plurality of slips,

wherein the segmented timing ring is actuated by one of a pneumatically, hydraulically, and electrically powered actuator;

wherein the lifting elevator is configured to laterally receive a joint of pipe between the first elevator segment and the second elevator segment when in an open position and the joint of pipe is disposed in a non-vertical position, and

wherein the lifting elevator is configured to grip and reorient the joint of pipe from the non-vertical position to a vertical position and lowered into a well when the first plurality of slips and the second plurality of slips are engaged with the joint of pipe in a closed position.

2. The lifting elevator of claim 1 , wherein the first elevator segment comprises a first tapered surface that the first plurality of slips are movably disposed along, and wherein the second elevator segment comprises a second tapered surface that the second plurality of slips are movably disposed along.

3. The lifting elevator of claim 1 , further comprising:

a non-moveable back stop disposed between the first elevator segment and the second elevator segment.

4. The lifting elevator of claim 1 , wherein the first lifting lug is positioned proximate to a middle of the first elevator segment, and wherein the second lifting lug is positioned proximate to a middle of the second elevator segment.

5. A method comprising:

opening a first elevator segment and a second elevator segment of a lifting elevator about a hinge connecting the first elevator segment and the second elevator segment, wherein the first elevator segment and the second elevator segment each comprise a swept angle of about 180°;

tilting the lifting elevator to a non-vertical position;

receiving a non-vertical joint of pipe within the opened, tilted lifting elevator;

closing the first elevator segment and the second elevator segment of the lifting elevator around the non-vertical joint of pipe;

gripping the non-vertical joint of pipe with a plurality of slips of the lifting elevator,

wherein gripping the non-vertical joint of pipe with the plurality of slips comprises moving the plurality of slips in a downward direction in a tapered bowl via a connection between the plurality of slips and a segmented timing ring, wherein the segmented timing ring is actuated by one of a pneumatically, hydraulically, and electrically powered actuator;

lifting the gripped, non-vertical joint of pipe to a vertical position using the lifting elevator,

wherein the lifting elevator includes a first lifting lug coupled to the first elevator segment and a second lifting lug coupled to the second elevator segment, and

the first lifting lug and the second lifting lug are configured to carry a load of the joint of pipe;

positioning the vertical joint of pipe atop a conductor string;

attaching the vertical joint of pipe to the conductor string; and

supporting the joint of pipe and the conductor string with the lifting elevator.

6. The method of claim 5 , wherein receiving a non-vertical joint of pipe comprises:

abutting the joint of pipe against a non-moveable backstop disposed between the first elevator segment and the second elevator segment.

7. The method of claim 5 , wherein the first lifting lug is positioned proximate to a middle of the first elevator segment, and wherein the second lifting lug is positioned proximate to a middle of the second elevator segment.

8. The method of claim 5 , further comprising:

latching the first elevator segment to the second elevator segment of the lifting elevator closed around the non-vertical joint of pipe using a latch.

9. The method of claim 8 , wherein:

the latch is pivotably connected to one of the first elevator segment and the second elevator segment.

10. The method of claim 5 , wherein each of the plurality of slips of the lifting elevator comprise a die configured to grip an external surface of the joint of pipe.
