The massive size of these tanks, in addition to extra weight from a previous re-lining, necessitated a creative strategy for removal. To accomplish this, RW Collins utilized a ‘tandem pick plan’ using two 100,000-lb excavators. Throughout the removal, our equipment operators maintained constant communication with the ground crew. These safety measures ensured a safe lift and transportation of the tanks. Once the tanks were removed, they were decommissioned and sheared onsite for recycling at a licensed facility.
