Abstract

A module for an engineering, procurement, and construction (EPC) project is described. The module comprises machinery disposed on a baseplate. The baseplate is coupled with a support structure via adjustable, self-leveling chocks. The chocks maintain a level baseplate surface regardless of whether or not the underside of the baseplate and the support structure are parallel. The chocks reduce and/or eliminate the transfer of the deflection forces from the support structure to the baseplate.

First claim

What is claimed is:

1. A method of transporting machinery in a modular fashion, comprising the steps of:
assembling a module that comprises the machinery, a baseplate, at least two support structures, and a plurality of self-leveling chocks by:
securing the baseplate to a first support structure by placing a first self leveling chock and a second self-leveling chock between the baseplate and the first support structure;
securing the baseplate to a second support structure by placing a third self-leveling chock and a fourth self-leveling chock between the baseplate and the second support structure;
placing the machinery on top of the baseplate and optionally securing the machinery to the baseplate;

transporting the module from a first location to a second location such that at least one of the first and second support structures experiences at least one of deflection, bend, or twist; and
wherein the self-leveling chocks reduce or isolate the transfer of at least one of deflection forces, bending forces, and twisting forces from the at least one of the first and second support structure to the baseplate.

2. The method of claim 1 , wherein the baseplate is substantially planar.

3. The method of claim 2 , wherein, during the step of transporting the module from a first location to a second location, the baseplate remains substantially planar.

4. The method of claim 1 , wherein each of the self-leveling chocks comprises:
a top annular member threadably coupled with a bottom annular member, wherein rotating the top annular member relative to the bottom annular member adjusts the vertical height of the self-leveling chock;
a washer having a substantially flat top surface and a convex bottom surface that slidably couples with a concave top surface of the top annular member; and
a through-hole disposed through the center of the washer, top annular member, and bottom annular member and that is sized and dimensioned to receive a bolt.

5. The method of claim 4 , wherein the step of securing the baseplate to a first support structure comprises:
placing the bottom annular members of the first and second self-leveling chocks on the first support structure;
placing the baseplate on the top annular members of the first and second self-leveling chocks;
aligning the through-holes of the first and second self-leveling chocks with holes on the baseplate and first structural support;
inserting a bolt through the through-holes of the baseplate, first and second self-leveling chocks, and first structural support; and
fastening a nut on each end of each bolt.

6. The method of claim 5 , further comprising the step of adjusting the height of the first and second self-leveling chocks before completely tightening the nuts.

7. The method of claim 5 , wherein the step of securing the baseplate to a second support structure comprises:
placing the bottom annular members of the third and fourth self-leveling chocks on the second support structure;
placing the baseplate on the top annular members of the third and fourth self-leveling chocks;
aligning the through-holes of the third and fourth self-leveling chocks with holes on the baseplate and second structural support;
inserting a bolt through the through-holes of the baseplate, third and fourth self-leveling chocks, and second structural support; and
fastening a nut on each end of each bolt.

8. The method of claim 7 , further comprising the step of adjusting the height of the first, second, third, and fourth self-leveling chocks before tightening the nuts to a specified torque.

9. The method of claim 1 , wherein the first support structure and second support structure are a steel I-beam.

10. The method of claim 1 , wherein underside surfaces of the baseplate and the top surfaces of the at least two support structures that come in contact with the self-leveling chocks have a flatness of 0.002 inches or better and a surface finish of Ra 250 micro-inches or better.
