Abstract
An anchorage line comprising a large number of successive elements interconnected in an articulated way and each including a closed watertight tube delimitating an interior volume full of air. The anchorage line comprises a shallow depth extremity providing the link with a floating vehicle and a very deep anchorage extremity providing anchorage on an ocean bottom. The floatability of the anchorage line varies according to its length. The tubular essential parts of the anchorage line have a wall thickness related to their diameter and which is thicker the nearer these parts are to the anchorage extremity of the line. The anchorage line may be assembled on site and put in place by a suitable device.
