Armato concrete seafloor cable protection

Offshore wind farms and offshore platforms where cables and pipes can be laid on the seabed and be protected by Armatos Cable Protection.

Armato protects sea-based cables against storms and ice. When tempest occur the cables are as most exposed as the waves are building up against windmill foundations, or in case of heavy ice impact.

At Väner Kraft’s wind farm in Vänern, the biggest lake in Sweden, Armato’s cable protection has been placed since spring 2009. Armato’s cable protection has been exposed to many storms and heavy ice impact in Vänern and has not been changing position or let the cables take any damage from natural forces.

Closest to the concrete foundation thecable protection is secured with a chain-cable.

Armato’s environmental friendly cable protection

Armato’s cable protection will become a habitat for fish and other marine life that is in need of an enhanced environment.

Armato protects sea-based cables against storms and ice.
Armato’s cable protection will with its many holes become habitat for fish and other marine life that is in need of an enhanced environment.

Armato’s seafloor cable protection is with its design to decrease hydrodynamic lift from wave energy and water streams, as well as eliminate erosion around the cable protection. The heavy weight, width, and vaulted shape of the cable protection, together with a strong linkage connecting the units, will make the cable protection stay securely on the seafloor. The linkage construction and the element design enables to place the elements in radius and above uneven grounds.

Armato cable protection has a concrete thickness of 20cm and is heavily armored in order to resist forces from wave movement, storms, ice, and fishing gear.

The linkage between the concrete elements is of flat steel 15x100mm 1 unit and 10x100mm 2 units, locked with M30 bolt. The linkage can be delivered untreated or galvanized.

The belt that secures the cable, both lateral and vertical, against the seafloor is aging-resistance, UV-resistance and withstands petrochemical substances. When the belt is 20cm width it has a tensile strength of 16000 N/20cm, the pressure against the cable is about 120kg, divided to about 160cm2.

Armato Marin AB offer sea cable protection for most uses and markets. It may be to protect fibre cable drawn to islands, cable protection for the cables when installing wind farms in the sea and offshore platforms. The sea cable protections can withstand difficult conditions and thus the application is wide.

In the sea there are good conditions for offshore wind turbines, thanks to appropriate depths, good wind conditions and proximity to connection to main grids and our cable protection. Our sea cable protection is mounted on the seabed and is custom-made to keep the cable in place in harsh and tough conditions that are exposed to difficult conditions and are oil resistant and withstand other aggressive stresses. Armato sea cable protection protects all kinds of offshore cables.

Maritime cable protection protects not only the cables, but also the sea and seabed. As these cable protections remain where they are placed, nature is not destroyed in the same way as if you do not use our cable protection. The sea should be used sustainably so choose Armato's sea cable protection when you are going to work marine. Cable protections protect not only the cable but the ocean in the long term.

Maritime cable protections are made of concrete and not only keep the cable in place below the surface but are environmentally friendly as there will be no plastic, no material ends up in the sea that does not belong there. Use our sea cable protection to work for how the sea should be used, now and in the future. The sea should be used sustainably!

We often act as subcontractors to suppliers who have been instructed to pull cable. These cable protections in concrete allow the cable manufacturer to keep their quality requirements against their customers. Has been used to protect fibre cable that has been pulled between islands in the archipelago to allow the cable to remain in place and the cables will not come loose and float up. Maritime cable protections fit all international standards of offshore cables.
Feel safe and choose Armato's sea cable protection!
