Service areas - Concrete mats
| Concrete Mats (a.k.a. “Pipeline Stabilization Mattresses”, “Sub-sea Mattresses”): |
Flexible, high-strength Concrete Structures
Separate, protect, and stabilize unburied pipelines, flowlines, and umbilicals situated on sea-beds, river-beds, and lake-beds
When placed over exposed lines, these flexible structures form a strong, wide-area blanket that stays in place, even in high-current areas
The hexagonal cross-section of the concrete blocks (or segments) are linked together with high-strength polypropylene rope linkages
The system is engineered to give the Mats maximum flexibility in both planes, so they conform completely to the coverage area
The design of the Mats allows for self-silting and proper separation between the pipelines. The silt-in process also aids in the Mat's underwater stability.
Because the Mats are typically only about 9” thick, or less, they provide maximum protection and stability with minimum interference of navigation
The Standard Concrete Mat size is 8’ x 20’ x 9” thick

Concrete Mats are deployed via a purpose-built Deployment Frame constructed of steel
The Deployment Frames can be modified to handle up to three separate Concrete Mats for multiple deployments
For shallow-water applications, Concrete Mats can be deployed by Divers
For deep-water applications, Concrete Mats can be deployed by Remote Operated Vehicles (ROV’s)
Prior to the introduction of Concrete Mat Technology, traditional protection was achieved through the use of sand/cement bags for pipeline crossings. More recently, articulated Concrete Mats have widely become accepted by Standards Organizations, Contractors, and Pipeline Operators

Quality of Construction
Costs Savings through ease of installation
Higher worker safety compared to sand/cement bag technology
Concrete Mats can allow access to pipelines, valves, or other protected structures, simply by removing the Mats used as cover, then replacing the same after maintenance
Concrete Mats have an indefinite lifetime in offshore and other under-water applications |
|
Separation of pipelines at crossings
Protection of exposed pipelines, flowlines, and umbilicals
Stabilization of exposed lines in high-current locations
Support on uneven sea-beds |
|
Typically, Concrete Mats will last well beyond the service life of the pipelines they are protecting
Neither the Concrete Blocks, nor the Polypropylene Rope, is subject to degradation or deterioration |
