What is a possible requirement after tank washing?

After tank washing, manual removal of residue is a necessary requirement to ensure that the tank is clean and free of any remains from previous cargoes. This step is critical because residual materials can contaminate future cargoes or create safety hazards. Proper cleanliness is essential for the integrity of the tank and the quality of the next load.

Manual removal typically involves physically cleaning the tank surfaces or using equipment designed for this purpose. Depending on the nature of the cargo and washing agents used, residue may not be eliminated through washing alone, necessitating additional physical effort to ensure that no contaminants remain.

Other processes may be involved in managing a tank after washing, such as allowing water to settle or other safety protocols. However, the manual removal of residues specifically addresses the cleanliness requirement vital for safety and quality in the handling of subsequent cargoes.
