1.0.1 This Code is formulated with a view to implementing relevant national principles and policies, unifying technical requirements and realizing technical advancement, economic rationality, safety and serviceability during the design of petroleum depot.
1.0.2 This Code is applicable to national petroleum depots for overground crude petroleum storage as well as commercial petroleum depots with total capacity larger than or equal to 120× 104m3; this Code is not applicable to the design of the petroleum depots and the refined petroleum depots of the following storage types: in underground rock cavity, underground salt cavern, outshore pontoon, caves, or buried underground.
1.0.3 The design of petroleum depots shall not only comply with the requirements specified in this Code, but also those in the current relevant standards of the nation.
2 Terminologies
2.0.1 National petroleum depot
State invested and constructed large petroleum depot for long-term crude petroleum storage.
2.0.2 Commercial petroleum depot
A large petroleum depot for crude petroleum storage operated independently by enterprises.
2.0.3 Petroleum depot
A general term of national petroleum depot and commercial petroleum depot.
2.0.4 Fired site
An indoor or outdoor fixed site with revealed flame or overheated surface.
2.0.5 Sparking site
A fixed site such as chimney with spotting fire, spot for outdoor grinding wheel, electric welding spot, autogenous welding (torch cutting) spot, etc.
2.0.6 Dike
A structure to prevent the outflowing of combustible liquid material leaked from the tank and fire spreading.
2.0.7 Intermediate dike
A structure dividing a group of tanks into several partitions so as to reduce the influence range of small-scale leakage accident within the dike.
2.0.8 A group of storage tanks
One or more tanks arranged within a dike.
2.0.9 Tank farm
An area formed by one or more storage tank groups, which takes the center line of fire-fighting passage surrounding the tank farm as the boundary.
3 Basic Requirements
3.0.1 Petroleum depot should store low-freezing crude petroleum.
3.0.2 The fire risk classification of crude petroleum shall be Class A.
3.0.3 Tank modulus determination shall comply with the principle of safety, economy and reasonability; the nominal capacity of single tank should not be less than 10 × 104 m3.
3.0.4 Living facilities and maintenance facilities for petroleum depot employees should rely on supplying from the society.
