Regarding Note 2 of Article 8.4.5 of the GB50160-2008 (2018) petrochemical code, shallow tray internal floating roof tanks are to be considered as fixed-roof tanks. Currently, shallow-dish internal floating roofs are no longer used in fixed-roof tanks; is it still necessary to include this in the standards?

"What does it mean that shallow-disk internal floating roofs can no longer be used in fixed-roof tanks? Note 2 merely states that shallow-dish internal floating roof tanks are calculated as fixed-roof tanks

Shallow-disk internal floating roofs have poor safety performance; Article 6.1.7(1) of GB50071-2014 explicitly prohibits their use
