This paper describes residual hydrate dissociation in a storage tank by heat conduction simulation. The suitable hydrate storage tank is necessary in the project which is supply the fuel gas by marine transport of natural gas hydrate. The amount of hydrate in the tank will change on demand. Two dimensional heat equation was solved using an implicit finite difference method namely the Crank-Nicolson scheme and Gauss-Seidel iteration technique. Temperature and hydrate volume fraction in a tank are calculated. The results of simulation indicated that the volume fraction of hydrate dissociation increases gradually with the heat-receiving surface.
