Further Development of Mechanised Ballast Cleaning
The desired properties of the ballast bed defined by the ballast structure will be lost if the quantity of fine particles in the ballast bed is much greater than the permissible proportion. On new ballast the permissible proportion of fine grain is normally 3 to 5 % of the total weight of the ballast specimen. (Normally ballast stones

Ballast/displacement ratio, and capsize screening ratio
Ballast/displacement ratio (often expressed as a percentage) is just the ratio of your ballast to your total displacement. Capsize screening ratio (normally expresses as a number) is your beam (in feet) divided by the cube root of your displacement (in cubic feet). CSR values less than 2.0 are considered OK for offshore.
