Preview of global ballast water treatment markets
have room aboard to accommodate them. It is assumed that
these smaller fishing vessels will need to find some other way
to comply with IMO ballast water regulations.
Age of the merchant fleet
In addition, the Lloyd’s merchant fleet data were sorted
according to age of ship. Table 4 shows the world fleet by
vessel type and age. The general cargo ship and fishing vessel
fleets are the oldest, which suggests they would be less likely
to adopt the treatment technologies approved by IMO to date.
The Table includes 2009 new-builds (1804 ships) listed in the
database as of November 2009. Because the IMO granted a
delay for the first set of ships subject to the regulations, (those
ships constructed in 2009 or later with a ballast capacity of
less than 5000m
3
) these ships now have until the vessel’s sec-
ond survey to comply although the ‘no later than 31 December
2011.’ This deadline will slip again because full ratification
did not occur before that date. More than 60% of the new
vessels listed as under construction in 2009 were bulk carriers,
container ships, or tankers that are estimated to have greater
than 5000m
3
ballast water capacity, which do not require
treatment technology for new builds until 2012.
BWTS EQUIPMENT AND INSTALLATION
COSTS
In order to assess and compare the cost of various BWTS,
technology vendors whose systems had been approved or
were close to approval by IMO as of May 2009 were con-
tacted by email and telephone. Additional information about
installation costs and logistics, and potential bottlenecks in
supply was collected through follow-up communications with
vendors and other industry representatives.
The following types of systems were evaluated:
l
Filtration and UV,
l
Filtration and chemical,
l
Deoxygenation and cavitation,
l
Electrolysis and electrochlorination,
l
Filtration, deoxygenation and cavitation.
Costs associated with purchasing, installing, and operating
each of these systems were estimated for a ‘typical’ ship in
each of the following ship type/size categories:
l
Bulker: Cape-sized vessel,
l
Bulker: Panamax,
