Question: When replacing the inner floating roof panel, must the wall thickness meet the specification requirements? (I hope someone on the device version can reply)
It mainly depends on whether there is any change in the design pressure; if there is no change, then the wall thickness should remain unchanged as well. It is possible to add a manhole in the wall. The manufacturing requirements are still a bit different.
This is a problem that often arises during the renovation of old equipment…… Old equipment was certainly designed and manufactured in accordance with old standards. However, during the renovation process, design firms, fearing liability, will recalculate everything using the current latest standards, which leads to a series of compliance issues that pose difficulties for the original users. Sometimes, when commissioning a design, it is necessary to define the scope and allocate responsibilities. When commissioning a design to modify floating platforms or seals, avoid expanding the scope; it’s important to clarify responsibilities among all parties. With mutual understanding, it might be possible to get things done, but it becomes difficult when dealing with more assertive design firms·····
