Concrete Fleximat

concrete fleximat 01

Østraadt Rør AS ’ Concrete fleximat is depending on its dimensions manufactured with a max quality concrete moulded in block mattresses with a Danline 14mm / 22mm UV stabilised polypropylene rope. Primarily used on subsea installations it's designed with a brick pattern matrix and offers a high degree of flexibility permitting it to follow the contours of the pipeline, umbilical and seabed.

FUNCTIONALITY

Stabilisation
Pipelines need to be stabilised from the forces induced on them by a combination of their self weight, any contained products and by the environmental (usually hydrodynamic) forces acting on them induced by wave, current and storm conditions.

Protection
Pipelines, flowlines, structures, instruments, valves and other features of subsea production equipment need protection from a variety of hazards such as vertically dropped objects which may fall from a platform, crane or drilling vessel, or from other hazards such as fishing or aqua culture.

COASTAL AREA PROTECTION

Østraadt Rør AS ’ Concrete fleximat is the perfect solution for the prevention of erosion on harbour installations and coastal areas. Østraadt Rør AS ’ Concrete fleximat combines durability with speed of installation. The flexible concrete block mats are fast and easy to install in sloped and flat beds.

Scour
Tides and currents cause erosion of the seabed and can also cause considerable damage to coastal areas. This phenomenon is known as scour.

With offshore installations placed on sandy seabeds the accelerating currents and increased turbulence can result in deep scour holes which might endanger the stability of the structure. To prevent this, scour protection measures need to be applied in order to avoid loss of stability of foundations and subsea structures.
