Abstract

L.N.G. is stored under pressure and near its boiling point in a heat-insulated vessel 20a having no ullage space and vapour evolved due to heat leak together with expanded liquid is vented through a duct 34 leading to a drum 38 of sufficient capacity to accommodate said vented vapour and liquid and having sufficient ullage space to provide for expansion and vaporization due to normal heat leak in the drum itself which latter has a pressure relief vent valve 61 in a discharge stack 62. A plurality of vessels 20a to 20n are vertically mounted in a ship's hold and have access ducts 21a to 21n connected by relief valve 36a to 36n to the vent duct 34 and by liquid block valves 27a to 27n to an insulated liquid header 26 having one end leading to the drum 38 and the opposite end connectable to a shore liquidfill and emptying line 11 and a pump 12 to a tank 10. The storage vessels have further access ducts 22a connected by relief valves 35a to 35n to vent duct 34 and by block valves 31a to a main uninsulated vapour header 30 connected at one end to drum 38 and connectable at the other end to a shore line 13 and a compressor 14 to the vapour space of tank 10. Vapour block valves 31a-31n are each controlled by a liquid sensor 32a to 32n whilst the liquid block valves 27a to 27n are controlled by vapour sensors 28a to 28n. The liquid level in drum 38 is maintained below a predetermined height by means 49 which withdraws excess liquid, vaporizes it and discharges either through valve 61 and stack 62 or through a line 55 to the ship's engines or to a burner 59. To fill the vessels 20a-20n and with shore lines 11, 13 connected to headers 26, 30 a valve 48 in header 26 is closed, valves 23a to 23n and open as are valves 15, 16, 29, 33 and pump 12 is operated and liquid flows through open liquid block valves 27a to 27n to the vessels 20a to 20n whilst vapour is forced through open valves 31a to 31n, header 30 and line 13 to tank 10. When a given vessel, say 20a, is filled with liquid, the level reaches a sensor 32a which then closes the liquid block valve 27a, which it controls, and filling is completed when sensor 32n closes valve 27n. During the voyage valves 23a to 23n and 27a to 27n are closed but valve 48 and vapour block valves 31a to 31n remain open whereby expansion liquid in access ducts 22a to 22n gains access to the uninsulated header 30 where it is vaporized and carried through the vent header to the drum 38.
