Abstract

A method of estimating a characteristic (Qn′, Q1′) of a load of liquefied natural gas being transported by a tanker at any point on a route (401, P; 501, 502, 503), the method being characterized in that the estimation is made by integrating, over the route (410, 411, 412, 420; 510, 511, 512) from a reference point (400, P; 500) at which said characteristic is known (Qn, Ql), a relationship associating the instantaneous transformation of the load with instantaneous navigation conditions.
