Oil is leaking from the central drainage of the crude oil tank; if the tank cannot be emptied in the short term, this is to prevent environmental incidents such as pollution or the sinking of the tank due to a floating roof. It is possible to use a flexible metal hose to connect the flange of the central drainage pipe to the discharge port flange or the water cut-off flange of this tank. During heavy rain, open the central drain pipe and the connected valve to allow rainwater to flow directly into this tank. Wait until the weather improves before proceeding with the water cutting operation.
Having experienced this, first, one can identify the source of the leak by locating it, check the condition of the floating tank as well as the secondary seals, in order to prevent the tank from sinking. Secondly, during heavy rain, the emergency shut-off valve can be closed and oil-absorbing felt can be laid. It is recommended to install underground pipelines that connect the open ditches with the accident ponds, so that oily rainwater can be directed into these ponds during storms, preventing oily wastewater from entering the open ditches and causing environmental pollution
