Air Casters Move 40 Ton Heat Exchanger on Gulf Oil Rig
A 40 ton heat exchanger was moved into position using 8 innoAIRvation LM series Air Caster Load Modules rated at 12,000 pounds capacity each. A challenging move due to limited crane access, the heat exchanger was loaded onto the casters via the drilling module crane, the modules were secured by integrated toe clamps, then moved into position where crane access was not available. Once in position, the casters were deflated onto 2 ½ high bearing pads and the Air Caster Load Modules were easily slid out for the heat exchanger installation and integration.
Due to the narrow contact of the 24-inch Air Caster Load Modules with the W8x35 wide flange I-beams, innoAIRvation incorporated toe clamps on top of the modules to securely attach the modules to the beam to ensure the modules would stay beneath the heat exchanger during the 150 travel path. Two clamps on one side of the flange guaranteed performance and security of the system.
A special 8-station control console was utilized to provide two methods of control. High flow R180 regulators were used to operate the LM24GHD modules in dual regulation where two modules were connected in series and regulated by a single regulator to simplify the control scheme, since the heat exchanger was balanced across the width. A BV skid weighing 7 ½ tons was moved after the heat exchanger using single regulation. The 8-tation special control console allowed for single or dual regulation of 8 Air Caster Load Modules.
Heat exchanger moved to final location resting on bearing blocks. The LM24GHDHLXR Air Casters 2 3/8-inch thick are slid from beneath the 2 ½-inch bearing blocks when the Air Casters are deflated. 15,000-pound BV skid is moved into location next to the heat exchanger using four 24-inch LM series Load Modules. Again, the BV skid was moved over the 2 ½-inch bearing blocks and deflated into position, then the Air Casters were slid from beneath the skid.
