Abstract

L'invention concerne un procédé de contrôle (1) d'un indice de méthane d'un gaz naturel liquéfié stocké dans une cuve (80) et comprenant une étape d'estimation (10) de l'indice de méthane du gaz naturel liquéfié, une étape de comparaison (20) entre l'indice de méthane estimé et un indice de méthane cible, et une étape d'ajustement actif (30) de la pression d'un ciel de cuve (82) en fonction de la comparaison entre l'indice de méthane estimé et l'indice de méthane cible. L'invention a également pour objet un système de contrôle (50) de l'indice de méthane du gaz naturel stocké dans la cuve (80). Application au domaine du transport maritime.
