Some embodiments are directed to a module for depressurisation and storage of a portion of a gas layer coming from at least one cryogenic tank. Some other embodiments are directed to a system using such a module.

Module and system for depressurising a cryogenic tank

This invention relates to a method and a system for calculating in real-time the duration of autonomy of a non-refrigerated tank containing natural gas comprising a liquefied natural gas (LNG) layer and a gaseous natural gas (GNG) layer. This invention also relates to a system for calculating, in real time, according to the method of the invention, the duration of autonomy of a non-refrigerated tank, as well as a vehicle comprising an NG tank and a system according to the invention.

Method and system for calculating, in real-time, the duration of autonomy of a non-refrigerated tank containing LNG

A method of estimating a characteristic (Q', Q&#x2032;) of a load of liquefied natural gas being transported by a tanker at any point on a route (P;), the method being characterized in that the estimation is made by integrating, over the route () from a reference point (P;) at which said characteristic is known (Qn, Ql), a relationship associating the instantaneous transformation of the load with instantaneous navigation conditions.
