Bulk Grain CargoProcess Of Cleaning Holds
Bulk Grain Cargo
Process of cleaning holds
1.Hold Cleaning – it can be done by a shovel or a swept clean.
The stevedores at the discharge port should swept the holds before completion of the discharge to minimize the remaining residues.
Hold Cleaning
2.Hold Washing Down – once sweeping and cargo residues are removed, the next task is to wash down the hatch cover and holds with saltwater. Hold Washing down
3.Use of chemicals - the use of prewash is to protect the paint coating of holds and allow for a much easier cleaning after cargoes are liable to stain.
Use of chemicals
4.Drying of Holds – when wash down is completed, the crew should mop up any pools of water that may have collected in tank top indentations and other areas. If the ship is fitted with mechanical ventilation, this should be run to aid the drying process for the rest of the hold.
Drying of holds
5. Fumigation –this is done before the voyage before or after loading full and clear instructions should be received from a charterers and shippers.
Fumigation
6. Hold inspection – The master or chief officer should accompany the inspector with two or three crews bringing brushes, shovels, rugs and a bucket, so that any minor problems that the inspector finds be immediately be remedied while he completes his inspection to the hold.

HOLD CLEANING IN BULK CARRIERS –
GRAIN
In the dry bulk trades, there are essentially
five grades of
hold cleanliness:
1. hospital clean, or ‘stringent’ cleanliness
2. grain clean, or high cleanliness
3. normal clean
4. shovel clean
5. load on top
Hospital Clean
Hospital clean is the most
stringent, requiring the holds to have
100% intact paint coatings on all surfaces, including the tank top, all ladder rungs and undersides of hatches. Grain Clean
Grain clean -The most common cleanliness requirement for bulk carriers is that of grain clean. A ship will be required to be grain clean for the majority of bulk and
