Cleaning of Holds

Before the ship can load her next cargo, the cargo hold must be adequately cleaned. The degree of cleanliness will depend on the nature of both the previous cargo and the next cargo.

Hold cleaning serves a number of purposes such as:

1. Facilitating inspection of the ship's structure, in order to detect any damaged part clearly;

2. Removing sources of combustion;

3. Promoting the free flow of moisture towards bilges and wells;

4. Preventing contamination of next cargoes;

5. Preventing the development of unsanitary conditions.

For break bulk cargoes and some dirty dry-bulk cargoes, it may be sufficient for the holds to be swept by the crew. For cleaner dry-bulk cargoes, the holds may be washed out with high-pressure hoses to remove all traces of the previous cargo. It is good practice to rinse the holds with fresh water after washing with salt water in order to minimize any future corrosion. Also, this may be essential if the next cargo can be damaged by salt. The highest standards of cleanliness are usually referred to as ‘grain standard’, which may be required for sensitive cargoes such as grain and other victuals.

For most cargoes, the holds must be dry and free from odours, which may taint the cargo. On reefers, it is particularly important that all traces of odours from previous cargoes are removed using an 'ozonator' to remove toxic gas in the hold.

The holds should be free from all loose rust which may contaminate certain sensitive cargoes. Some inspections may require the hold to be specially coated with lime for salt or sulphur cargo.

11 Read the text and underline all measures to be taken for hold cleaning.

12 Correct the mistakes made by the deck cadets.

Carl W. “The holds must be ventilated whenever there is odour or not.”

Quewt L. “The cleaning will depend on the cargo deadweight and ship’s draft in salt water.”

Morri O. “The highest standards of cleanliness refer to the hold sweeping.”

Swank S. “After the dirty dry-bulk cargoes it’s required to coat the hold with lime.”

Abraham C. “The future corrosion can be avoided by washing with salt water.”

13 Complete and give your partner some advice.

1. To clean the holds it may be sufficient ________________________________________them.

2. To remove all traces of the previous cargo you should _____________________________________________________________________________.

3. To transport salt and sulphur cargo you’d better _____________________________________________________________________________.

4. To minimize any future corrosion it’s recommended ____________________________________________________________________________.

5. To remove all traces of odours and toxic gas you must _____________________________________________________________________________.

6. To transport sensitive cargoes you should _____________________________________________________________________________.

14 Discuss.

WHY…

must all sources of combustion be removed from the holds?

must there be a free flow of moisture towards bilges?

must unsanitary conditions be prevented?

15 Read the case and answer.

a) How many times were the holds cleaned?

b) What was the demurrage time?
