Preview of global ballast water treatment markets
Vessel type
Data were analysed by type of ship for ‘delivered’ ships listed
in the Lloyd’s
Fairplay
database. It was 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, only vessels of 300gt or more were included. Other
sub-types that were determined as not carrying ballast water
or that would only be operating within one ‘Captain-of-the-
Port Zone’ (COPTZ) were also excluded. Ballast capacity
was then estimated for different sized vessels in each sub-type
fleet. Information for actual ships listed in the American
Bureau of Shipping database were used as the basis for esti-
mating ballast capacity for ships of various sizes in various
ship classes.
Analyses indicated 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
1500–5000m
3
. These ships will be required to have bal-
last water treatment starting in 2014. Of those ships, the
great majority – more than 16 000 – are general cargo
ships (Table 2a). Of US-flagged vessels, it was estimated
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 (Table 2b).
About two-thirds of the demand for installation of technol-
ogy to meet IMO D-2 Standard will be associated with
meeting the 2016 deadline for ships with less than 1500m
3
capacity (more than 16 000 ships) and with more than
5000m
3
capacity (more than 29 000 ships).
While naval ships are exempt from the ballast water
management requirements and are not included in these
statistics, it appears that the navies of several countries
will choose to comply with IMO regulations at least for
non combat operations. All NATO navies have agreed in
principal to comply, so this represents a significant market
segment. If US and NATO navies fitted BWT systems to
all classes of surface warships 5000mt and larger, over
200 vessels would be included, totaling approximately
3 000 000mt.
Vessel size
The Lloyd’s database was further sorted by deadweight
tonnage to develop a more comprehensive view of the
various-sized vessels in the world merchant fleet subject
to ballast-water regulations (Table 3). Again, in the case of
fishing vessels, only those of 300gt or more were included
in the analysis. More than 92% of an estimated 8001 fishing
vessels subject to IMO ballast water regulations are less than
1000dwt. Given the slim operating profit margins of smaller
fishing vessels, it is unlikely that they will be able to afford
the types of BWTS that are the focus of this research, or will
