Structural performance evaluation of innovative prestressed concrete floating fuel storage tanks

Prestressed concrete (PC) tanks have been widely used in industrial applications and are commonly constructed as base-supported structures. Inland–space-constrained cities, it may be viable to construct such facilities as floating structures in sea areas. Several innovative conceptual designs of floating fuel storage tanks, including double- and single-hull structures, are first proposed in this paper. For this new type of fuel storage facility, the self-weight and in-fill fuel are balanced by buoyancy forces, and there is no need for massive foundations.
