Two massive reactors, each weighing nearly 3 million pounds and standing 23’ tall, journeyed from the Port of New Orleans up the Mississippi River to a refinery in the Southeast. From transportation to final placement, the project required customized solutions at every step to address the unique challenges of the route, site and massive loads.
Marathon Bridge
Multiple roll-off scenarios were developed to account for the Mississippi River’s ever-changing water levels, with surveying teams conducting precise field measurements to ensure perfect alignment throughout the transport corridor. To ensure the transport could adapt to fluctuating river levels and meet strict Army Corps of Engineers specifications, Deep South engineered and constructed a specialized heavy-haul bridge from scratch to carry the reactors over the Mississippi River levee and its adjacent road.
From ship-to-barge transloading at the port to precise roll-off operations and railroad crossings due to stringent railroad requirements, every phase demanded meticulous planning and real-time problem-solving. Deep South used 28 axle lines of triple-wide Scheuerle SPMTs for roll-off and 28 axle lines of double-wide Scheuerle SPMTs for in-plant transport.
From transport to final lift
But delivering these colossal reactors to the refinery was only the beginning. A second challenging phase lay ahead: lifting each 3-million-pound reactor into its final position.
Following the Deep South-facilitated reactor transport, the team was tasked with lifting the two reactors into position, each weighing nearly 3 million pounds and measuring 143’6” long x 21’6” wide x 23’ tall. The operation required Deep South’s 2,500-ton VersaCrane™ TC-36000 in a customized Configuration 6. This was Deep South’s heaviest field lift in company history.
Marathon Lift
The lift presented its own set of site-specific challenges, including a confined space that required a new approach to tailing the reactors. To support the massive lift and eliminate the need for a tail crane, the team used a newly designed and fabricated 1,000-ton tailing frame mounted on a 12-axle-line, quadruple-wide Scheuerle SPMT trailer.
Deep South also custom-engineered and fabricated a 2,000-ton hydraulic pin puller for safe, hands-free rigging attachment and detachment, which eliminated the need for an additional assist crane with a man basket. Deep South’s custom steel mats and bridge ramps helped to achieve optimal load distribution for Configuration 6, with 1.2 million pounds of main counterweight and 2.8 million pounds of hinge counterweight.
After nearly three years of extensive planning and one year of construction and execution, the job was completed safely and on time thanks to strong teamwork and careful coordination with the client. From the custom-built heavy-haul bridge to the customized crane configuration, newly engineered tailing system and hands-free pin puller, the project required a tailored solution at every stage.
When the challenge requires more than standard solutions, Deep South delivers.
