STORAGE TANK FLOOR EVALUATION Date 2/21/2023MINIMUM REMAINING THICKNESS (MRT) CALCULATIONS File No Report No Client Inspector Tank No Temp (deg F) Canary 3134C Canary Renewables Corp.Gavin Kopp T-633 3134C 100.0 Liner CP Protec 50mil Liner RPB Ca Shell tmin Shell tnom D H S Select Select Select Select 0.250 38.0 30.0 Where; Ca = corrosion allowance, in (inch). MRT = minimum remaining thickness at the end of interval Or. This value must meet the requirements of Table 4-1 and sections 2.4.7.4 and 2.4.8. Or = In-service interval of operation (years to next internal inspection) not to exceed that allowed by 4.4.2. RTbc = minimum remaining thickness from bottom side corrosion after repairs. RTip = minimum remaining thickness from internal corrosion after repairs. StPr = maximum rate of corrosion not repaired on the top side. StPr = 0 for coated areas of the bottom. The expected life of the must equal or exceed Or to use StPr = 0. tmin = minimum allowable thickness in accordance with requirements of Table 4-1 and sections 2.4.7.4 and 2.4.8. to = bottom plate original thickness. UPr = maximum rate of corrosion on the bottom side. To calculate the corrosion rate, use the minimum remaining thickness after repairs. Assume a linear rate based on the age of the tanks. UPr = 0 for areas that have effective cathodic protection. D = nominal diameter of tank, in (ft), H =Height, in (ft), from the bottom of the 1st shell course to the maximum allowable fill height S=Stresses are calculated from 2.34(H-1)DG/SE.
