Abstract
The present invention concerns a method for applying insulation to a combined cylindrical tank for storage of liquefied gas. One or more layers of a polymer foam (2) are sprayed onto the exterior surface of the tank shell (1). Crack barriers (4) are mounted on top of certain layers of the polymer foam (2), wherein the crack barriers (4) are anchored to the exterior surface of the tank shell (1). The invention also concerns a corresponding combined cylindrical tank for storage of liquefied gas, as well as the use of such a combined cylindrical tank for storing and/or transporting a liquefied gas.

1-20. (canceled)
A method for applying insulation to a combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type for storage of liquefied gas, the method comprising:
- providing a combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type comprising a tank shell (1);
- spraying one or more layers of a polymer foam (2) onto the exterior surface of the tank shell (1);
- and
- mounting one or more crack barriers (4) on top of one or more layers of polymer foam (2), wherein the one or more crack barriers (4) are anchored to the exterior surface of the tank shell (1) in connection area(s) of cylindrical sections of the combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type.
A combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type for storage of liquefied gas, the combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type comprising:
- a tank shell (1);
- one or more layers of a polymer spray foam (2) covering the exterior surface of the tank shell (1);
- one or more crack barriers (4), mounted on top of one or more layers of polymer spray foam (2) and anchored to the exterior surface of the tank shell (1) in connection area(s) of cylindrical sections of the combined cylindrical tank of bi-lobe, tri-lobe or multi-lobe type.
