As of March 31, 2012:• 33 member States representing 26.44%33 member States representing 26.44% shipping tonnage had ratified the Convention
• It may enter into force next year
• More than 30,000 ships will have to comply ¹
• Only 200 do so today ²

42+ potential BWT plant makers evaluated
12 makers pre‐selected based on our well‐defined criteria
Final selection narrowed down to 3 plants: based on cost, weight, footprint, etc.
Three BWT plants identified as potential solutions for our shipssolutions for our ships

Maker list update
Preliminary investigation completed
8 additional Makers identified as possible8 additional Makers identified as possible contenders to the three selected 2011
Cost of tests for Makers to obtain IMO D2 Approval is approx €1 MillionApproval is approx €1 Million
N i ti t h l i dNo innovative technologies emerged
None of the 8 makers betters the 3 plant selected during the 2011 investigation
Noticeable efforts made to improve filtration
