One-point anchor system

The invention relates to a single-point anchor anchor for seagoing vessels, in particular tankers, which is connected to a loading or unloading device, and in particular to one in which an anchor buoy is fixed with a single anchor shaft which also serves as a conduit for the liquid cargo, a device being provided in the anchorage which allows the buoy to rotate freely under the influence of a ship's movement i .

Y / ird a ship with a single buoy in the way moored so that it can move freely around them, so one speaks of a one-point anchoring. The mooring is carried out by means of a bracket attached to the bow. Ropes, and that The ship is able to describe an angle of 360 ° around the buoy, which reduces the anchor forces. In the meantime must the transfer of the liquid cargo between the ship and the underwater pipeline remain secured during the movement of the ship. In order to avoid adverse effects on the anchor system and the loading or unloading system, at previous one-point anchor systems use buoys that set themselves via four or even more anchor chains and required expensive hose connections to the pipeline.

The invention creates a single-point anchor and loading or unloading system that is more economical by comparison. Discharge functions fulfilled by a single anchor shaft will. .

More precisely, the invention creates .ym single-point anchor system with a single anchor shaft that:.

IBAD ORIGINAL

the entire anchor shaft is under tension, with one 5? Eil of this anchorage at the same time as a line for the liquid charge is used. In order to be able to absorb the movement of the ship, the anchor shaft is designed in such a way that that he flies the buoy free. Rotation by one allows vertical axis through the center of the foundation. In addition, to avoid excessive stresses from to keep the anchor shaft is a non-rotatable, flexible one and pivotable connection provided with which the anchor shaft is fixed to the foundation. Through this care is taken to ensure that only an axial load occurs in the anchor shaft.
