FIGURE 1 LEVEL OF CLEANLINESS
Hospital clean
DEFINITION
Hospital clean requires the holds to be completely clean. dry, and free of all loose scale. It also requires fully intact paintwork of all surfaces in the hold.
Grain clean
Completely clean. dry, odour-free, and gas- free. All loose scale is to be removed.
CARGOES THAT MAY BE ASSOCIATED WITH THIS LEVEL OF CLEANLINESS
• Chrome Ore • Fertiliser • Fluorspar • Mineral sand • Rice in bulk • Soda Ash
• Cement • Fertiliser • Grain • Sugar
• Seed cake • Sulphur
Normal clean
Less rigorous than grain clean, but still requires the hold to be swept, clean, dry and free of any residues of the previous cargo.
Shovel clean Load on top
Cargo is removed by mechanical means, such as a grab, or manually via shovels. Several tonnes of the previous cargo may remain.
Loading the same cargo on top of the residue of the previous shipment. This is only allowed for certain types of cargo, and the hold must be clean enough to prevent contamination of the new cargo.
Hold washing
The process of hold washing on ships involves critical considerations for safety and effectiveness. A comprehensive risk assessment by the ship’s master is essential, encompassing chemical usage, provision of accurate data (SDS), and adherence to safety measures. During paused cargo operations, crew members may access upper cargo hold areas after a risk assessment and permission from authorities.
Cleaning starts with hatch covers and deck areas, with attention to potential water entry and compliance with local wash water regulations. Sweeping debris, using appropriate cleaning chemicals, and considering cargo residues’ impact on bilge systems are emphasized.
Adequate fresh water for a final rinse is crucial to prevent chloride traces, which can lead to failed cleanliness inspections and coating issues. The text provides a detailed guide for efficient and compliant hold washing procedures.
Preventative measures
To protect their position and avoid disputes or claims, shipowners should consider the following:
- Conduct pre-loading inspections to ensure that the hold is clean and free from any residues or contaminants. This helps in identifying any potential issues before loading cargo.
- Maintain accurate records of hold cleaning activities, inspections, and any communication with charterers regarding hold cleanliness. These records can serve as evidence in case of disputes or claims.
- Maintain open and transparent communication with charterers regarding hold cleanliness. Inform them of the cleaning procedures followed, any issues identified during inspections, and any necessary remedial actions taken.
- Chartered entries should consider the differential in hold dimensions and hatch size when fixing a ship. The differential may mean
• Coal • Petcoke • Salt
• Iron Ore • Bauxite
• Iron Ore
• Coal, if the same grade of coal has been contractually agreed to be carried over an extended period.
that both a grab and bulldozer are required to discharge the cargo, considerably increasing discharge time.
- Remove as much cargo residue as possible at the discharge port, with local and MAPROL regulations always considered. This will better prepare shipowners in the event unforeseen circumstances, such as adverse weather.
- Local requirements may be more stringent than those typically experienced. Australia and the US are known to be areas with more strict requirements and shipowners should consult their local agents for up-to-date information on requirements in discharge ports.
