Renovation of internal floating roofs under the new oil tank codes
Thread Content
The new oil storage tank specifications require the use of internal floating roofs for liquid chemical products classified as Category A-B and Category B-A. My colleagues in the design firm, when dealing with renovations that involve changing the contents stored in tanks, do we need to replace the existing fixed roofs with internal floating roofs? The specifications state in the general provisions that for the design of existing oil depot renovation and expansion projects, only the design of the expanded and renovated sections shall comply with the latest version of the specifications; the existing parts do not need to be modified in accordance with the new requirements. When changing the product in a storage tank, does that tank still count as part of the existing inventory? If an accessory is added to the tank, does it still count as part of the existing tank?
The renewal of equipment and facilities whose construction scale, overall layout, unit functions, and location remain unchanged does not fall under the category of renovation. In other words, everything you already have remains unchanged; it’s just a device upgrade, which falls within the scope of normal maintenance and repair. But in your case, since you have changed the product, that is, your construction scale has changed, it falls under renovation and must comply with the new regulations.
