Abstract (en)
[origin: EP0947420A1] The anchor consists of a metal spiral (10) made from heat treated steel or steel alloyed with silicium or vanadium which is screwed into the plant layer (40). The length of the spiral can be from one to several meters, its diameter of several dozen centimeters, and its pitch from a dozen to several dozen centimeters. A length of mooring line attached to the anchor is selected so that it lies at an angle of 30 - 60 degrees to the sea bed. Where necessary, a number of anchors can be inserted in a row and connected by a bar.
