Abstract
A system for transporting and deploying a natural gas processing system comprises a base. In addition, the system comprises a plurality of natural gas processing units mounted to the base. Further, the system comprises a plurality of jacking units attached to the base and configured to raise and lower the base. Each jacking unit comprises a post, an upper lift member moveably coupled to the post, a lower lift member moveably coupled to the post, and a pair of actuators. Moreover, each actuator has an upper end coupled to the upper lift member and a lower end coupled to the lower lift member.

A system for transporting and deploying a natural gas processing system, comprising:
- a base;
- a plurality of natural gas processing units mounted to the base;
- a plurality of jacking units attached to the base and configured to raise and lower the base;
- wherein each jacking unit comprises:
- a vertical post having a longitudinal axis and plurality of vertically aligned, axially spaced holes;
- an upper lift member slidably coupled to the post;
- a lower lift member slidably coupled to the post and fixably attached to the base;
- a pair of actuators, wherein each actuator has an upper end coupled to the upper lift member and a lower end coupled to the lower lift member;
- wherein the upper lift member includes an upper sleeve disposed about the post and a pair of arms extending from opposite lateral sides of the upper sleeve;
- wherein the lower lift member includes a lower sleeve disposed about the post below the upper sleeve and a pair of arms extending from opposite lateral sides of the lower sleeve;
- wherein the upper sleeve and the lower sleeve each include a throughbore;
- a first pin removably disposed in one of the holes of the vertical post and the throughbore in the upper sleeve;
- a second pin removably disposed in one of the holes of the vertical post and the throughbore in the lower sleeve.
A method for transporting and delivering equipment to a deployment location, comprising:
- (a) mounting the equipment on a base;
- (b) positioning the base on a transport vehicle;
- (c) transporting the base and the equipment to the deployment location with the transport vehicle;
- (d) coupling a plurality of jacking units to the base, wherein each jacking unit comprises:
- a vertical post having a longitudinal axis;
- an upper lift member slidably coupled to the post;
- a lower lift member slidably coupled to the post and attached to the base;
- a pair of actuators, each actuator having an upper end coupled to the upper lift member and a lower end coupled to the lower lift member;
- (e) incrementally lifting the base to a first height relative to the ground with the jacking units at the deployment location;
- and
- (f) moving the transport vehicle from beneath the base while the base is disposed at the first height;
- (g) lowering the base to a second height relative to the ground with the jacking units after (f), wherein the second height is less than the first height;
- wherein (e) comprises:
- (e1) fixing the position of each lower lift member relative to its corresponding post;
- (e2) actuating the actuators to move each upper lift member axially upward along its corresponding post after (e1);
- (e3) fixing the position of each upper lift member relative to its corresponding post after (e2);
- (e4) actuating the actuators to lift each lower lift member axially upward along its corresponding post after (e3);
- (e5) repeating steps (e1) to (e4) until the base is moved upward a desired distance.
A method for processing produced natural gas at a wellsite, comprising:
- (a) mounting a gas processing system to a base;
- (b) positioning the base and the gas processing system mounted thereto on a first transport vehicle;
- (c) transporting the base and the gas processing system to the wellsite with the first transport vehicle;
- (d) coupling a plurality of jacking units to the base, wherein each jacking unit comprises a vertical post, an upper lift member slidably disposed about the post, a lower lift member slidably disposed about the post and attached to the base, and a pair of actuators coupled to the upper and lower lift members;
- (e) extending each vertical post downward into engagement with the ground or support disposed on the ground;
- (f) moving each lower lift member upward along its corresponding post after (e) to lift the base and the gas processing system mounted thereto from the first transport vehicle.
