Nearly 500 axle lines of self propelled modular transporter (SPMT) were used to move the largest modules so far loaded in to the GCGV plastics plant construction project.

At the peak of the project Mammoet had 1,578 lines of SPMT in operation on the Gulf Coast Growth Ventures (GCGV) site in Texas, USA. GCGV is a joint venture between Exxon Mobil and Saudi Arabian petrochemical company SABIC, set up to develop a plastics manufacturing facility in San Patricio County.

Dedicated road

To move the largest module Mammoet used eight sets of SPMT, each with 62 axle-lines, for a total of 496 axle-lines. Before making the moves an almost 5 mile (8 km) temporary road was especially built for the project. It crossed Highway 181 and the FM 2986 roads which were closed to allow the transports through. Mammoet worked with the Texas Department of Transportation to make the closures at times least inconvenient for other road users.

Commenting on the moves Wendell Johnson, Mammoet project manager, said, “Mammoet is pleased to have the opportunity to provide our equipment and expertise to GCGV. We are proud to have been selected as a valued team member and strive to continuously deliver our part in bringing this facility to fruition.”

SPMT was brought in from six Mammoet depots around the world, drawing from its total fleet of more than 4,700 axle lines.
