Abstract
The flexible mattress-like element is used as ballast or a load for immobilising and protecting underwater pipelines (6). It includes an outer flexible envelope (7), pref. made from a non-woven fabric, covering at least one gabion which is made from double-twist, hexagonal-mesh wire netting in the form of a parallelepiped. This is filled with a mixture of stones or pebbles (8) with a sand-filler, and bitumen-based mastic (9). Each gabion is made from panels of netting in which the portions of wires which are twisted together are pref. arranged transverse the length of the gabion, that is, parallel to the axis of the pipeline to be immobilised and protected.
