Articulated concrete block systems acbs are an effective countermeasure if properly designed and installed.

Articulated concrete mattress. The technology and relative merits of the system will be outlined along with case history examples of usage in africa as listed below cotonou benin abidjan ivory coast tanzania. Production as close to your loadout site as possible to minimise transportation costs. Our quality concrete flexible mattresses support stabilize and protect all sorts of subsea installations used by major oil and gas contractors.

Articulated concrete block mattresses acbm for pipeline and subsea protection broadline construction is the leading provider in subsea pipeline protection systems and seabed soil protection systems. The articulated concrete block mattress acbm is a rectangular unit made of concrete blocks joined together by polypropylene ropes. Articulating concrete mats acm provide the best solution for covering and securing exposed pipelines.

A unique staggered block design to reduce current flow through the mattress and reduces scour under mattress. Uv stabilised polypropylene rope and high strength concrete to ensure the required design life for the mattresses is exceeded. Armorflex blocks have specific tested hydraulic capacities and are laced longitudinally with revetment cables to provide ease of handling and rapid installation.

Our dynamic design allows the mat to conform to any pipeline and maintain its stability on the seabed. The mattress is flexible in two dimensions and is available in a range of thicknesses to suit the conditions required. Armorflex armorflex is a flexible interlocking matrix of cellular concrete blocks of uniform size shape and weight used for hard armor erosion control.

Concrete mattress has been used for berth scour protection for some 50 years providing a good understanding of performance. The density of concrete used in the manufacture of standard mattresses is generally between 23 and 25 tonnes per cubic metre. A matrix of individual concrete blocks placed together to form an erosion resistant overlay with specific hydraulic performance characteristics.

Waskey articulating concrete mats are a dynamic system comprised of concrete cells interlinked with 400 feet of extruded copolymer rope. This article will cover acb design including the safety factor analysis and overturning moment design approach outlined in hydraulic engineering circular no. The mattress is flexible in two dimensions and is available in a range of thicknesses to suit the conditions required.

Under certain conditions where there may be a requirement for additional or less weight in a mattress or other sps products sps can design and supply a concrete mix with a higher or lower density than the standard.
