Abstract

La présente invention concerne une structure isolante destinée à une partie d'angle à 90° d'une cale de méthanier, une cale de méthanier comportant cette structure isolante et un procédé de construction pour fabriquer la cale. Une structure isolante triangulaire est prévue sur une partie d'angle à 90° d'une cale, et un panneau d'angle à 135° est prévu sur la surface inclinée de la structure triangulaire. Par conséquent, le nombre de types de panneaux est réduit, ce qui permet d'améliorer la gestion des produits pour la fabrication et l'installation. Et des cannelures membranaires sont placées sur une partie d'angle à 90° d'une cale, le nombre des cannelures ainsi que l'intervalle entre celles-ci pouvant être réglés, ce qui confère un avantage structural par rapport à un rétrécissement thermique à ultrabasse température.
