Articulated Concrete Mats (ACM)

WASKEY Mats have quickly become the leader in the offshore industry providing unparalleled quality design along with WASKEY’s attentive customer service. WASKEY’s patented, non-shielding/non-abrasive boots (U.S. Patent No.: 8,858,118) and pads feature a unique anchoring system that prevents peeling and provides unmatched pipeline protection.

Product Overview

WASKEY Articulating Concrete Mats are a dynamic system of 160 concrete cells interlinked with 400 feet of extruded copolymer rope with a minimum tensile strength of 9,600 lbs. The engineered shape of each concrete element allows it to articulate on a two axial plane. The concrete, rope and non-abrasive PVC boots or PVC pads all have a working life that meets or exceeds that of the pipelines or structures they serve.

Articulating Concrete Mats (ACM) provide the best solution for covering and securing exposed pipelines. Our dynamic design allows the mat to conform to any pipeline and maintain its stability on the seabed.

WASKEY’S PATENTED PVC BOOTS AND PADS

Waskey’s PVC boots and pads are an integral part of the mat element, providing complete non shielding/non-abrasive protection for cables, umbilicals and pipelines. The unique patented (U.S. Patent No.: 8,858,118 and 9,518,366) design of Waskey’s non-abrasive boots and pads protect against cathodic shielding of pipelines by enabling water to flow freely between the boot/ pads and pipeline wall to ensure non-interference with the pipelines cathodic protection system. Waskey’s elite anchoring systems provides unmatched pipeline protection while protecting against peeling during the application process.

Offshore Applications

Articulating Concrete Mats (ACM) provide the best solution for covering and securing exposed pipelines. Our dynamic design allows the mat to conform to any pipeline and maintain its stability on the seabed.

Waskey Articulating Concrete Mats are a dynamic system comprised of concrete cells interlinked with 400 feet of extruded copolymer rope. The engineered shape of each concrete element allows it to articulate on a two axial plane. The concrete, rope and non-abrasive PVC boots or pads all have a working life that meets or exceeds that of the pipelines or structures they serve.

Waskey also offers a Log Mat which is comprised of 4 - 12” steel reinforced concrete hexagon logs interlinked with copolymer rope. The design has been proven effective in providing a stable subsea foundation for crossing configurations as well as temporary subsea work platforms.

Onshore Mat Applications

Waskey’s environmentally friendly concrete mats are an effective solution for a variety of soil stabilization issues and geo-technical failures. They are easily installed on river and stream banks as well as shorelines. Environmentally friendly engineered mat systems are an effective long-term solution for pipeline protection in right-of-ways as well as slope stabalization on waterways.

LOG MATS

The Waskey Logmat offers a superior foundation base for supporting pipelines and subsea construction where poor soil conditions exist. The Waskey Logmat is comprised of 4-12” steel reinforced concrete hexagon logs interlinked with copolymer rope. The Waskey Logmat’s durable construction makes it a safe and economical means to achieve strength and stability in uncertain seabed conditions.

The design has been proven effective in providing a stable subsea foundation for crossing configurations as well as temporary subsea work platforms. The Waskey Logmat is efficiently and accurately deployed utilizing Waskey’s Deployment Frames. Waskey stocks standard sizes of 8’ x 20’ and 8’ x 40’ but can quickly supply any custom length Logmat to fit the client’s specifications. table

Engineered Deployment Frames

Waskey’s diver/ROV friendly, dual and single release deployment frames were developed from a proven design and are engineered for deepwater dependability and safety. Waskey’s deployment frames allow for numerous variations in mat orientations and quantities per deployment. Waskey’s specialized deployment frames make precise mat placement to the seabed possible with a performance record that is unmatched for safely delivering the largest number of concrete mats to the seafloor in the least amount of time. table
