A separate MERC report titled: “Preliminary Analysis of Ballast Water Treatment Costs”
includes detailed analyses of purchase, installation, and fixed annual operating costs (e.g.,
maintenance) and variable annual operating costs (per metric ton of ballast treated) for selected
ships in the eight types/sizes of vessels. This report is available at http://www.maritime-
enviro.org/reports/Reports.html and presents all of the assumptions used to develop preliminary
cost estimates and the vessel-specific cost development spreadsheets that were used to develop
the cost estimates and resulting market value estimates presented here. The cost spreadsheets
presented in that earlier report can be modified and refined easily to accommodate new cost data
or different ship types/sizes/patterns of use. A summary of our preliminary cost analysis of fixed
annual maintenance costs is in Table 7 below.

* Includes fixed annual costs (e.g., BWTS maintenance) as well as annual costs that vary with the amount
of BW treated. Filtration/Chemical system cost estimates vary significantly by ship type and by the
amount of ballast treated because of the the cost of consumables. (e.g., chemicals).
Using life-cycle costs per metric ton of ballast treated, we estimate that Filtration/UV and
Electrolysis/Electrochlorination appear to be the least expensive solutions for most types/sizes
(Table 8). For all ship types/sizes, not enough data were found on Filtration, Deoxygenation and
Cavitation systems to include this treatment system type in our analysis.
