Lo present invention provides a device which will facilitate dock at wharf very large tonnage ships.

in the conventional harbor, provided for vessels to 60,000 tonnes iii. üüG, very easy to control and which are extremely appropriate for reaor -

- quage, low fixed defenses are sufficient to avoid interference with the structures of the violent auai, the stoppers or dukes the dolphin, that can harm the hull vessels.

uvec the rapid growth of tonnage of oil tankers and ainéraiiers, the tonnage their considerable random access imparts a force, very difficult to control at the time of i ' accosted-

ge-. L-a docking speed is to in effect be less than I? / cns second tower that does result in severe damage to the platform of the. defenses navire.des. and of the special devices are even indispensable for monitoring at any time the speed of the ship. they do not avoid the accident.

device me, 1 object ' invention! is, allows rapid braking of the docking of the ship speed so as to reduce to the optimum value.

Oe device is characterized by a mobile defense auai 7par a set métallioue and articulated spring, having one part integral to the platform per movable joints and the other part of which, in a plane parallel to that of the platform, can by a motion perpendicular thereto docking braking the speed.

Oet guard assembly is practiced as follows:
