For 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 ).Tank Jacking Procedure Oil Storage Tank Installation GuideJacking Method.Jacking method is a kind of storage tank installation method that refers to the bottom of storage tank as the reference plane,the wall in the top of the storage tank and the tank roof will be installed firstly,then assemble and weld the storage tank wall from top to the bottom of the storage tank until the installation of tank bottom is completed.TECHNIQUES METHODOLOGIES FOR TANK BOTTOMSuch crude oil storage tanks may be of fixed roof or floating roof types,designed and constructed in accordance with API 650 standard.These crude oil storage tanks (steel- butt welded) are subjected to reversible stress of the tank bottom or the annular plate within 3 inch ( 76 mm) of the inside edge of the tank
