Articulated Concrete Mat Design

This paper provides guidance for the design fabrication and installation of articulated concrete mat slope protection.

Articulated concrete mat design.

This article will cover acb design including the safety factor analysis and overturning moment design approach outlined in hydraulic engineering circular no. The mats are made of a matrix of individual concrete blocks placed together to form an erosion resistant overlay with specific hydraulic performance characteristics. Our dynamic design allows the mat to conform to any pipeline and maintain its stability on the seabed. Articulated concrete blocks acbs provide a hard armor surface that can be used as an alternative to concrete rip rap or other permanent erosion control systems.

Erosion is slowed when marine vegetation gains a foothold. The design and construction of these alternative systems is not addressed in this manual. Articulating concrete mats acm provide the best solution for covering and securing exposed pipelines. An acb system is comprised of a matrix of individual concrete blocks placed together to form an erosion resistant revetment with a geotextile underlay for subsoil retention.

Articulated concrete mat erosion control oil and gas pipelines pipeline erosion control submar submar has long been a leader in pipeline erosion control. Although articulated mat armor has been utilized for many years in low energy wave environments it has been extended recently to accommodate intermediate wave energies and severe ice loads. Experience selection and design guidance third edition volume 2 hec. Increasingly abundant vegetation will promote sedimentation and enhance the stability of the area where mats are used.

Bridge scour and stream instability countermeasures. Articulated concrete block systems acbs are an effective countermeasure if properly designed and installed. An articulated concrete mat s unique design helps to even out the seabed by allowing sand and plant matter to settle between the blocks making up the mat. Articulating concrete block acb systems are used to provide erosion protection to underlying soil from the hydraulic forces of moving water.

The company has continuously been on the forefront of innovation designing new products that help assist those in the oil and gas pipeline industry with onshore and offshore pipeline exposure remediation. And published in the. Shoretec is a leader in the design and manufacture of these systems. Waskey articulating concrete mats are a dynamic system comprised of concrete cells interlinked with 400 feet of extruded copolymer rope.

Our articulated concrete block acb system is durable aesthetic and an environmentally compatible solution at a cost savings of up to 50 when compared to traditional hard armor methods.
