In order to avoid the damage occurring and the great effort required for this purpose, it has been proposed to surround the components located on the ship deck with plastic plates and to defrost them in some form by vibration. This technology has been found unsatisfactory. The invention is therefore based on the object to prevent the formation of ice on the pipes and to facilitate ice removal.
