Storage tanks, Fixed-roof tanks, Floating roof tanks ...Jul 01, 2019 · Floating roof tanks should be electrically grounded to the main tank shell (Bouquegneau, 2007). Careful consideration should be given to the design and placement of the seals and shunts to reduce the risk of ignition. Multiple shunt connections should be placed between the tank shell and floating roof at intervals of no less than 1.5-meters.

Floating roof tank allow the explosive gases in petroleum tanks to vent to atmosphere in a safe way. Today controlled gas venting in to the atmosphere is becoming more and more important due to environmental regulations. Compared to fixed roof storage tanks, fuel loss due to evaporation in floating roof tanks is considerably less.Oil Storage - an overview | ScienceDirect TopicsA total of 34 tanks were built with floating roofs, while the remainder were built with fixed roofs. After about five years of operation, the facility was expanded with an additional tank farm consisting of 5 tanks with diameter of 1825 m and height of 31.3 m.Tank Shell - an overview | ScienceDirect TopicsFor floating roof tanks, multiple shunt connections at 1.5-m intervals around the roof perimeter are recommended (Bouquegneau, 2007). Interestingly, in some cases tank shunts have been found to actually increase the risk of fires during lightning storms, as they are a source of sparking when hit by lightning ( LEC, 2006 ).
