After a period of navigation or berthing, marine organisms will grow and reproduce on the surfaces of ship hulls, propellers, decks, and other parts.
If there are no cargo residues, oil stains, or other environmentally harmful materials on the deck or in the bulk carrier holds, and no detergents harmful to water quality have been used, current regulations do not prohibit cleaning the deck or cargo holds.
Before cleaning the cargo hold, the hatch cover, hatch coaming, and main deck should be cleaned first to avoid bringing impurities into the hold.
Operations involving bulk carriers require careful planning and preparation to maintain cargo quality and avoid voyage delays and disputes, with cargo hold cleaning being a critical aspect of all preparations.
