1
Includes initial purchase and installation of ballast water treatment system.
2
Annual fixed operating costs do not vary with the volume of ballast water treated (ship size),
and exclude time costs that vary with volume of ballast water treated. Annual fixed operating
costs include crew, consumables, parts, estimated breakage, industrial assistance, and technical
support.
3
Includes costs that typically vary with the volume of ballast water treated such as crew costs,
consumables, fuel costs.
4
Includes capital costs, annual fixed operating costs, and per MT BW treatment costs. Assumes
143,000 MT BW treated per year and 25-year life of treatment system.
5
Lifecycle costs divided by 25 years (not discounted).
6
Lifecycle costs divided by estimated MT ballast water per year based on an expected 25 year
BWTS operating life.
7
Not enough data found on Filtration, Deoxygenation & Cavitation Systems to include.
