Presentation Transcript
In February 2004 the International Convention for the Control and Management of Ship’s Ballast Water and Sediments, 2004, was agreed
ballast water management convention 2004
Ballast Water Management Convention, 2004
  • Enters into force
  • 12 Months after ratification by 30 States with 35% world’s GT
  • As of October 2010, 27 States (25.3%) have ratified the Convention.
  • Now realistic to project ratification requirement to be met by Mid 2011 and EIF Mid 2012 (MEPC 62?)
the problem is that the dates are fixed
The Problem is that the dates are fixed!

MEPC Resolution 188(60)

“Recognising that while the requirements of Regulation B-3.3cannot be enforced prior to entry into force of the BWM Convention, it should be clearly understood that the ballast water management systems installed on ships constructed in 2010 will have to meet these requirements once the Convention enters into force”

practical considerations
Practical Considerations
  • Japan has estimated that approximately 62,000 BW Treatment Systems will require fitting in this decade
  • New buildings of approximately 1400/year
  • Shipyard capacity (approx 100 shipyards) where are the fitting facilities?
  • BWMS Manufacturing capacity??? Availability is unknown
  • From NOW circa 20 ships/day require systems to be fitted to attain Convention compliance requirements!
  • Largest chokepoint identified by Japan as 2017

45 systems/day will be required to be fitted in 2017!

  • Proposed US Federal and State regulations demanding standards greatly in excess of Convention standards raise additional uncertainty
present state of bwts development towards type approval
Present state of BWTS development towards Type Approval


  • 31 BWTS have been reviewed under the G9 IMO approval process
  • 10 BWTS have received Final Approval, 7 via G9 with 1 withdrawn (one not informed to IMO yet)
  • 1 system awaits G9 Final Approval and 2 others await evaluation for G9 Basic Approval by the GESAMP-BWWG
some relevant considerations in choosing the suitability of a bwts
Some Relevant Considerations in Choosing the suitability of a BWTS
  • Capital Cost
  • Running Costs
  • Footprint (include maintenance needs)
  • Power Consumption
  • Filtration needs
  • Level of Operator input required
  • Maintenance demands
  • Rate of Flow
  • Safety of Chemical storage
  • Chemical Availability
  • Water conditions in operating areas
    • Turbidity
    • Salinity

Shipowners and Shipyards are now being required to make a substantial financial commitment – we have to get it right!The considerable challenges associated with the selection of suitable equipment and retrofitting must be met!Forward Planning is Paramount!
