Trelleborg Moves Away from Traditional Container and Bulk Freight Quay Projects

US Military Enlist Company's Help to Prevent Another New Orleans Disaster
Shipping News Feature

US - Trelleborg is a name more usually associated with the nuts and bolts of the shipping business, producing as it does items such as the fender systems which protect the quays and wharves of some of the world’s largest container and bulk freight terminals. Recently however the Swedish headquartered company, Trelleborg Marine Systems, part of Trelleborg Engineered Systems, was able to rapidly supply materials for the Inner Harbor Navigation Canal (IHNC) Surge Barrier project. The nearly two-mile-long surge barrier is a key component in the U.S. Army Corps of Engineers’ ‘Hurricane and Storm Damage Risk Reduction System’, designed to better protect the greater New Orleans area.

The IHNC surge barrier is a new feature, similar to a floodwall but much larger, that has been designed and constructed to reduce the risk of storm damage to some of Louisiana’s most vulnerable areas – New Orleans East, metro New Orleans, the 9th Ward, and St. Bernard Parish. This project aims to help protect these areas from storm surges coming from the Gulf of Mexico and Lake Borgne.

During Hurricane Katrina, a storm surge travelled to the confluence of the Mississippi River Gulf Outlet and the Gulf Intracoastal Waterway just 8 miles east of New Orleans, LA, and entered the Industrial Canal. Following this, many sections of existing levees inside New Orleans were overtopped or compromised causing wide spread flooding in New Orleans and surrounding areas. The new INHC Surge Barrier structure will help to reduce the risk of events such as this in the future. Faiyaz Kolsawala, regional sales director for Trelleborg Marine Systems said:

“We were delighted to be chosen to work with Traylor Bros., Inc. and Shaw Environmental and Infrastructure, Inc. on this massive project. We worked closely in the design and planning stage of the project and it’s satisfying to see all the hard work now coming together.”

Trelleborg’s ability to provide the required materials within a demanding construction schedule helped it secure the contract. Trelleborg’s NC3 anchors were used to fix rub rails made of ultra-high-molecular-weight polyethylene (UHMW-PE) to approach walls leading to the surge barrier structure Once supplied and installed, this will be the largest known project carried out using cast-in NC3 anchors manufactured from 100% stainless steel A316 material, all produced in the USA in compliance with Buy American Act requirements.

The Trelleborg’s NC3 anchors give much higher shear ability and higher concrete pull out strength compared to traditional anchors, and an installation that is completely flush with the concrete face, and in so, eliminate any potential of thread damage. For the project constructors, this eliminates the need for drill-in-concrete anchors, potentially saving the costly resources of time and labour.
