Notes: 

Data included in this spreadsheet was taken directly from Ballast Water Treatment Technology - Current Status , Lloyd's Register (September 2008), and from MEPC Reports.

1

 Where applicable. Systems that employ an "Active Substance," defined by the IMO as "a substance or organism, including a virus or a fungus that has a general or specific action on or against harmful aquatic organisms and pathogens," are assessed according to the IMO approved Procedure 

for Approval of Ballast Water Management Systems that make use of Active Substances (frequently referred to as the ‘G9 Guidelines’).

2 The ballast water treatment system testing procedure is outlined in the IMO’s Guidelines for Approval of Ballast Water Management Systems (frequently referred to as the ‘G8 guidelines’).

4

 Per Lloyd's Register (Ballast Water Treatment Technology - Current Status (September 2008)), testing may not strictly meet IMO standards.

3

 Data on units installed and on projected production was provided by vendors to Lloyd's Register during Lloyd's research of ballast water treatment systems. The numbers listed here are based solely on this vendor-supplied information as reported by Lloyd's (see Ballast Water Treatment 

Technology - Current Status , Lloyd's Register (September 2008)).
