Load-Dispersing System From Uni-Mat Used In Transport Operation

Davenport/Mammoet, Rosharon, Texas, recently utilized an interlocking, load-dispersing mat system from Uni-Mat International, Inc., Houston, Texas, for transport of a heavy pressure vessel.

For the transport operation, a section of the deck of a 182- by 54- foot barge was decked using Uni- Mats. The primary purpose of the decking of the barge was to prevent high point loads from damaging the metal deck.

The layout pattern for the ninety 8- by 14-foot Uni-Mats used was such that each Uni-Mat was interlocked into and on top of four bottom Uni-Mats, thereby reportedly decreasing the loads on the deck section by 75 percent when compared to conventional mats. The total load on the barge was 830 tons—the 630-ton pressure vessel and 200-ton self-propeller hydraulic trailer assembly.

After the four-hour installation of the Uni-Mats, Davenport/Mammoet installed conventional timber mats for cradle sections for the splitter tower to rest on. The pressure vessel unit was loaded on the barge at Lake Charles, La., and transported to Sulphur, La., for installation as part of a major ethylene plant under construction.
