HFO Bund Empty and Clean

HFO Bund Empty and Clean (Heavy Fuel Oil) 

Case Study: Removal of Sludge and Contaminants from Decommissioned Tank Site

Task:

Remove all waste and clean the bund ready for masonry works

Solution:

After the decommissioning and removal of a tank at the site, a substantial amount of heavy sludge and contaminants remained, requiring further cleanup before the bund could be prepared for masonry works. Our team took the following approach to ensure the area was safe and ready for contractors:

1. Assessment and Preparation:

   • The sludge that had formed in the bund was too thick to be removed by jetting or pumping methods, so a manual approach was required.
   • The surrounding area was carefully prepared to prevent any accidental spillage of contaminants into the soil. This step was crucial in maintaining environmental safety throughout the process.

2. Sludge Removal:

   • Using small plant equipment, our team began the manual removal of the sludge. We excavated the material in manageable sections, ensuring that each phase of the process was controlled and efficient.
   • The sludge was transferred into UN approved containers, which were then palletized for easy transportation to a licensed waste facility for proper disposal.

3. Bund Cleaning:

   • After the sludge removal, the bund was thoroughly cleaned, ensuring it was free of any remaining oil or contaminants.
   • The site was left in a safe and clean condition, allowing the contractors to proceed with the necessary masonry works without any risk of contamination.

Conclusion:

Through careful planning and execution, we successfully removed all waste and cleaned the bund, making it ready for the next phase of construction. By using a combination of manual labour and small plant equipment, we were able to safely and effectively handle the sludge removal, ensuring the site was fully compliant with environmental standards.

The bund was left oil-free and safe for the upcoming masonry work, minimising delays in the overall project timeline.
