This list of eight ship type/size categories is not comprehen-
sive with regard to the scope of global fleet affected by the
proposed IMO regulations, but provides a fair representation
of the cost profiles for purchasing, installing, and operating
the BWTS that were analysed over a range of typical applica-
tions. No examination was made of vessels that routinely treat
less than 70 000 metric tons of ballast water annually, since
these vessels are likely to end up using alternative methods
to be in compliance with regulations, such as continuing to
use ballast water exchange if allowed, taking on fresh water
for use as ballast, or foregoing ballasting when in restricted
or regulated waters.
Base and bulk prices for different types of units were
calculated as averages of quoted purchase prices for that
type of system. For Filtration/UV light, three quotes were
received; for Filtration/chemical, three quotes were received;
for Deoxygenation/cavitation, one quote was received; for
Electrolysis/electrochlorination, three quotes were received.
The lowest quote received for purchase of any type of system
was $400 000 for one of the Filtration/chemical systems;
the highest quote was $1 670 000 for a Filtration/chemical
system from another vendor.
Based on analysis that incorporated information from
vendors and other sources, the range of expected BWTS
purchase costs across system types and categories of ship
types/sizes listed above was estimated to be $640 000 to
$947 000 (Table 5).
For all types of systems, there are some economies of
scale when purchasing bulk orders (eg, 10 ships), reducing
the cost of a system by $40 000 to $100 000 per unit, depend-
ing on the system type. It is important to note that installation
costs will vary widely even within a particular ship type/size
depending on the characteristics of individual ships and the
space and other requirements of specific types of BWTS. A
significant factor affecting cost will be the number of BWTS
required for a particular vessel. As a general rule it has
been assumed in the majority of cases that a system will be
installed aboard each qualifying vessel. However, depending
on the number of ballast pumps aboard, at least two BWTS
may be required. Additionally, on larger vessels containing
very large volumes of ballast water, multiple BWTS may be
required to handle the huge flow rates involved. This will
significantly affect the amounts shown in Table 5, which
