Height of the fire dike for liquefied gas storage tanks

It’s a spherical tank, 2000 m3 in capacity

According to Clause 6.3.5 of the Code for Fire Protection Design of Petrochemical Enterprises GB50160-2008, the installation of fire dikes and partitions shall comply with the following provisions: 1. For liquefied hydrocarbon storage tanks equipped with full-pressure or semi-refrigerated systems, a fire dike no higher than 0.6m should be installed. The distance from the base of the dike to the storage tanks should be no less than 3m. The floor inside the dike should be made of cast-in-place concrete, and it should slope outward. The partitions inside the fire dike should not be higher than 0.3m；

Is this solid wall that is no taller than 1 meter the same as a fire dike that is 0.6 meters high?

A 1-meter-high physical wall and a 0.6-meter-high fire dike are not the same thing; the construction regulations and those for the petrochemical industry differ

“An “physical wall” refers to the type of fire dike, that is, the fire dike itself

Should we implement petrochemical standards?

To allow any leaked liquefied gas to dissipate as quickly as possible, the liquefied gas storage area does not have very high fire dikes; in accordance with petrochemical standards, these dikes must not be higher than 0.6 meters

A physical wall refers to a fire dike； Height issue: Depending on the nature of the project, the relevant code provisions must be followed. Petrochemical standard – 0.6m ； Building Code – 1.0m ； Urban gas – 1.0m.

They are not the same thing. Regulations are documents that fall within the category of laws; the usage of terminology is consistent. If something is referred to as a solid wall, then it is not a fire dike, and if it is a fire dike, it cannot be called a solid wall – substitution is not allowed. I understand that the solid wall to be constructed around a tank farm as specified in the Building Code refers to the need to build an additional solid wall in order to ensure the safety of facilities located outside the tank farm. This is necessary when there is already a fire dike around the tank farm, along with a fire protection perimeter outside that dike; such a wall separates the tank farm from other facilities that are not related to it. In this way, even in the event of an accident, fire-fighting water or water contaminated by the accident will not spread. Otherwise, with only a 0.6-meter-high fire dike in place, it would not be possible to ensure safety during an accident. This solid wall serves primarily as a means of providing safety protection.

So what is the answer to this question?
