MJCronin- tank to be converted from oil storage to industrial wastewater storage. Floating roof ro be removed due to concerns with ice when converted to water storage. Tank already has a fixed roof in addition to internal floating roof.
Thanks JStephen and Duwe6. Tank will be used again, so would rather not cut hole in side. Which API Stds or guidelines specifically should be reviewed?
Are there published guidelines or recommended practices or procedures for how to remove an internal floating roof from an existing tank with a fixed roof? Also, should we be concerned with affecting structural integrity of the tank by removing the floating roof?
