Mammoet transports seven vessels from Spanish port to Texas plant

By Hannah Sundermeyer19 March 2022

Noatum Project Cargo contracted Mammoet to move the seven vessels over the road from the port to an ethylene to alkylate plant located in Pasadena, Texas.

After sailing from the Spanish Port of Algeciras, seven reactors needed to be unloaded and carefully transported at the Port of Houston in Texas. Global transport company Noatum Project Cargo contracted Mammoet to move the seven vessels over the road from the port to the final project site - an ethylene to alkylate plant located in Pasadena, TX.

The 972,912 pound deisobutanizer is placed on Mammoet’s SPMTs for offload.

During the planning process, the team came to realize that the preferred bolstered load trailer configuration for over-the-road transport would not be approved by the Texas Department of Transportation, the company said. This configuration would overload two bridges encountered along the route, as the heaviest vessel made the crossing using a relatively small number of axles.

The standard solution for increasing the footprint of the trailers would be to add dollies that extend out from the sides of the trailers and push down to increase the trailer’s overall footprint, spreading the load more evenly over a larger area, when engaged. Unfortunately, the width of the bridges in question would not accommodate the addition of traditional dollies.

SPMTs are used to transport the vessel from barge to site.

Mammoet and Noatum’s engineering teams proposed a solution to add a third trailer underneath the load at the belly of the vessel, which would expand the trailer footprint while not overloading the two bridges, and also not expand the width of the transport overall.

The six smaller reactors were discharged from the ship directly to Mammoet trailers, and then transported over the road approximately 7 miles from the port to the project site. The largest piece, a deisobutanizer weighing 972,912 pounds and measuring 198 feet, was offloaded from the ship by two specialized heavy lifting barge cranes.

The cranes tandem lifted the vessel from the ship onto two double 12-line Goldhofer PST Bolster trailers pre-staged on a waiting barge, floated to a nearby roll-off area, successfully rolled off and then transported overnight to the project site to cause minimal impact on area traffic.
