Vessel Types in Potentially Affected Global Fleet
We analyzed data by type of ship for “delivered” ships listed in the Lloyds Fairplay database,
and our analysis determined that the sub-types listed in Tables 2a and 2b would be subject to
IMO regulations for ballast water treatment. In the case of fishing vessels, we included only
vessels of 300 gross tons or more, and we excluded other sub-types we determined were not
carrying ballast water or would only be operating within one captain of the port zone (COPTZ).
We then estimated ballast capacity for different sized vessels in each sub-type fleet, using
information for actual ships listed in the American Bureau of Shipping database as the basis for
our estimates.
Our analysis indicates that more than 21,000 ships will be subject to the first round of IMO
retrofit requirements, which includes those ships with ballast water capacity of 1500-5000 m3.
These ships will be required to have ballast water treatment starting in 2014.

Of those ships, the
vast majority—more than 16,000—are general cargo ships. (See Table 2a.) Of U.S.-flagged
vessels, we estimate that only 183 ships will be in this first category of vessels required to retrofit
by 2014, with 131 of those ships either being general cargo or refrigerated cargo ships. (See
Table 2b.)
About two-thirds of the demand for installation of technology to meet IMO D2 Standard will be
associated with meeting the 2016 deadline for ships with less than 1500 m3 capacity (more than
16,000 ships) or with more than 5000 m3 capacity (more than 45,000 ships).
