Cargo hold cleaning | hospital clean | grains standard |

Cargo hold washing is the process of cleaning the cargo holds of bulk carriers, general cargo ships, and other vessels to remove residues, dust, and contaminants from previous cargoes. It ensures that the hold is clean and ready for the next load, especially when switching between different types of cargo (e.g., from coal to grain).
Key Reasons for Cargo Hold Washing:
Prevent Contamination: Essential for food-grade cargo like grain or sugar.
Comply with Regulations: Many ports and charterers require holds to meet cleanliness standards.
Maintain Vessel Integrity: Washing prevents corrosion by removing acidic or reactive residues.
Improve Efficiency: A clean hold ensures proper cargo loading and discharge.
Cargo Hold Washing Process:
1. Cargo Residue Removal: Sweeping, scraping, or using pneumatic or vacuum systems.
2. Pre-wash Rinse: High-pressure water washing to loosen remaining dirt.
3. Chemical Cleaning (if needed): Using alkaline or acid-based detergents to remove stains and residues.
4. Freshwater Rinse: Prevents saltwater corrosion.
5. Drying: Ensures the hold is dry before the next cargo, especially for hygroscopic cargo like grain.
6. Inspection & Final Cleaning: Checking for any remaining residues or rust spots.
Common Equipment Used:
High-pressure washers
Chemical sprayers
Scrapers and brooms
Dehumidifiers and blowers for drying
