Type de risque

Flood

Type d'unité d'installation industrielle

Storage Tank

Description

Damage states due to the hydrodynamic effects of the flood waters.

Etats

No	Code	Nom	Description
1.	DS0	None	No damage.
2.	DS1	Floatation	Uplift and displacement of storage tanks due to buoyancy.
3.	DS2	Shell Buckling	Buckling leading to shell collapse due to an external pressure above the critical pressure.
4.	DS3	Sliding	Rigid sliding of unanchored tanks due to the hydrodynamic pressure of the flood surge.
5.	DS4	Debris Impact	Impact with waterborne debris and other floating objects (e.g. storage tanks).
