See page 4 of the cited article under the heading equipment:
- Compartments larger than 7,500 litres should be loaded either less than 20% or more than 80% of the max. capacity.
- Compartments larger than 7,500 litres, which have to load orders with a volume between 20% and 80% of the max. capacity should have baffle plates dividing the compartment into areas of max. 7,500 liters.
A virtually identical article can be found for an installation at Moederdijk at the following reference:
