Adjustment of unevenness

Adjustment of unevenness

Adjustment of unevenness (patented)

Filter units can be used quickly and reliably to compensate for uneven surfaces of the seabed for cable and pipelines.

The single-lifting point enables a fast and safe installation; it also facilitates decommissioning after many years. Positioning can be done by ROV, diver or other position determining technologies. However, it should be highlighted that a diver in the water is not essential during installation, using ROV or sonar has been proven be the most efficient method of installation which significantly reduces Health and Safety risks.

The nets are extremely durable due to their PET fibers. The high quality of the nets is reflected in the remaining tensile strength after 50 years in salty water which still remains up to 79.5%. 

The nets are filled via a specially designed filling frame. This frame reduces time, equipment and manpower to a minimum.  Intermediate storage, stacking and transport of the filled nets is possible.

Free-span adjustment under J-Tube

Filter units are suitable for securing cables routed through the J-tube. Here, the space between the end of the J-tube and the point where the cable rests on the seabed can be bridged.

A key feature of Filter Units is the high flexibility, as the structure allows them to adapt to the seabed without further preparation.

The nets are extremely durable due to their PET fibers. The high quality of the nets is reflected in the tensile strength, which, according to tests, after 50 years in salt water still remains up to 79.5%. This means that Filter Units can be easily removed a long time after their installation.
