Abstract (en)
[origin: WO2017017364A2] The invention relates to a device for operating a pumping device associated with a sealed and thermally insulated tank (2); said tank (2) containing a liquefied gas (8) having a liquid phase and a vapour phase and having a multilayer structure comprising a sealing membrane (7) in contact with the liquefied gas (8) and a thermally insulating barrier (6) arranged between the sealing membrane (7) and a bearing structure (4), said thermally insulating barrier (6) comprising solid matter and a gaseous phase; said pumping device comprising a vacuum pump (16) connected to the thermally insulating barrier (6) so as to place the gaseous phase under a negative relative pressure; said method planning to control the vacuum pump (16) on the basis of a reference pressure Pc1 and of a measurement of the pressure Pi of the gaseous phase of the thermally insulating barrier (6); said method further comprising: - measuring the temperature T of the liquid phase of the liquefied gas (8); and - determining the reference pressure Pc1 by means of a relationship Pc1 = f1(T); f1 being an increasing monotonous function.
