Armato’s seafloor cable protection is with its perforation of holes designed 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.
