Abstract: A vacuum-insulated line (200) has an inner and an outer corrugated hose (101, 102) which are separated from one another by an evacuated intermediate space (103). One of the corrugated hoses is encased with a wound hose (201). The wound hose (201) prevents the line (200) from becoming elongated when it is charged with pressure during the transport of a medium. The wound hose (201) furthermore protects the line against external mechanical loads or damage. The wound hose simultaneously protects the corrugated hoses against excessive bending.

Abstract: A monitoring device (118) for monitoring the leak-tightness of a vacuum-insulated system has a corrugated bellows (108) which is connected in terms of flow to an evacuated space (104) of the vacuum-insulated system in such a way that, in the event of an increase in pressure in the evacuated space, the length of the corrugated bellows (108) is adjusted beyond a threshold value. A position detector (113) connected to an energy store (115) responds to the change in length of the corrugated bellows and outputs a signal. The position detector outputs a signal to a display device (116), which provides an indication if a leak in the vacuum-insulated system occurs.

Abstract: A vacuum-insulated line (200) is proposed which has an inner and an outer corrugated hose (101, 102) which are separated from one another by an evacuated intermediate space (103). One of the corrugated hoses is encased with a wound hose (201). The wound hose (201) prevents the line (200) from becoming elongated when it is charged with pressure during the transport of a medium. The wound hose (201) furthermore protects the line against external mechanical loads or damage. The wound hose simultaneously serves as a means for protecting the corrugated hoses against excessive bending. Also proposed is a loading station having a vacuum-insulated line.

Abstract: The invention relates to a method for operating a liquefied gas storage tank (1) having a tank volume (2) for receiving LNG and boil-off gas (BOG), wherein a gaseous BOG stream and a liquid LNG stream are fed to the tank volume, and wherein the BOG stream is introduced into the LNG stream, and wherein subsequently the resulting BOG-LNG mixture is introduced into the tank volume. The invention also relates to a corresponding liquefied gas storage tank.
