Barnhart performed roll off operations, on site transportation and the setting of a splitter column (180' long x13' diameter and 150 tons) and a reactor (80' long x 9' diameter and 90 tons) at a local refinery.

The vessels were part of the refinery's low sulfur fuels project. The reactor and splitter were fabricated in the Houston area, and were loaded on a deck barge and shipped to Memphis. Barnhart then rolled the splitter off utilizing Goldhofer platform trailer with bolsters on 2 sets of trailer and used a single trailer to roll off the reactor. Both vessels were staged on site earlier this summer, and were insulated on the ground.

While the insulating commenced, Barnhart moved in their Demag TC3000 (800 Ton Class Truck Crane) with 236' of main boom and decked with full basic and superlift counterweight. The crane set up was extremely tight with superlift tail swing issues as well as requiring exact outrigger placement to avoid above and below ground obstructions. The boom also had to be erected across a levee with a 180 ton and 50 ton RT crane due to limited set up area.

Barnhart then transported the reactor through the plant under several pipe racks and made a 90 degree turn around the plant's flare stack and down a narrow alley up to a low piperack. An LTM 1400 - 500 ton hydraulic crane was then set up behind the reactor to perform tailing operations. The reactor was lifted and set in less than one hour.

Next, the splitter column was transported on 15 lines of platform trailer through the plant with inches of clearance around the piperacks. The splitter was brought up to the low piperack and Barnhart then attached their tailing device to the platform trailer to tail the 150 ton column. Due to careful engineering and skilled field crews, both vessels were lifted over live process lines and safely set on their anchor bolts. The tailing device saved the customer time and money over a large tail crane as well as minimized the amount of time the road was blocked.
