2 Ballast water management & systems (BWMS): Consulting and Development for the Maritime Sector Management of G8 and G9 test and approval phase BWMS Consultants to IMO and GESAMP Strategic development of BWMS Company and fleet mapping of BMW implementation White papers on BWM regulatory requirement and interpretation Risk assessment and exemption from BWM regulation

3 Outline 1-slide course in invasive species problems in shipping BWMC Key strategy to avoid further problems Methods to accomplish that How far are we and what are the challenges Alternatives: Exceptions and Exemptions Onshore/Alongside treatment Freshwater Solid ballast, ballast free, continuous flow-through ballast 29 oktober 2012 Skibsteknisk Selskab 3

4 Invasive species problems in shipping 29 oktober 2012 Skibsteknisk Selskab 4

5 Key strategy to avoid further problems - KILL THEM ALL Ballast water management convention Ballast water exchange Ballast water treatment Countries Tonnage Special BW rules in countries (ICS: at least 34 entries) 36 (30) 29.08% (35%) Hull fouling: MEPC.207(62) 2011 Guidelines for the control and management of ships' biofouling to minimize the transfer of invasive aquatic species 29 oktober 2012 Skibsteknisk Selskab 5

6 Mechanisms to accomplish all that killing Filter Typically um Disk or Drum Treatment UV Electrolysis Ozone Biocide Time in tank Various (0-24 h) Re-treatment on discharge UV systems More and more common Neutralization For chlorine and ozone based systems 29 oktober 2012 Skibsteknisk Selskab 6

13 Vessels to be retrofitted MEPC (Japan) 29 oktober 2012 Skibsteknisk Selskab 13

14 BWMS installed Reported to MEPC 64 by China, India, Hong Kong (China), Sweden, Japan and South Korea Construction year Number of ships Less than 1,500 Ballast water capacity (m3) 1,500 and 5,000 Greater than 5,000 Before BWMS installed Systems ordered Total Between BWMS installed and 2011 Systems ordered Total After BWMS installed Systems ordered Total oktober 2012 Skibsteknisk Selskab 14

15 BWMS installed flow rate Reported to MEPC 64 by China, India, Hong Kong (China), Sweden, Japan and South Korea Construction year Number of ships Ballast water flow rate (m3/h) Up to and 2,000 Greater than 2,000 Before BWMS installed Systems ordered Total Between BWMS installed and 2011 Systems ordered Total After BWMS installed Systems ordered Total oktober 2012 Skibsteknisk Selskab 15

16 BWMC Guidelines Guidelines for sediments reception facilities (G1) Guidelines for Ballast Water Sampling (G2) Guidelines for ballast water management equivalent compliance (G3) Guidelines for Ballast Water Management and Development of Ballast Water Management Plans (G4) Guidelines for ballast water reception facilities (G5) Guidelines for Ballast Water Exchange (G6) Guidelines for Risk Assessment under Regulation A-4 (G7) Guidelines for approval of Ballast Water Management Systems (G8) Procedure for Approval of Ballast Water Management Systems that make use of Active Substances (G9) Guidelines for approval and oversight of prototype ballast water treatment technology programmes (G10) Guidelines for Ballast Water Exchange Design and Construction Standards (G11) Guidelines for sediment control on ships (G12) Guidelines for additional measures including emergency situations (G13) Guidelines on designation of areas for ballast water exchange (G14) Guidelines for Port State Control Interim Survey Guidelines under resolution A.948(23) Guidance to ensure safe handling and storage of chemicals and preparations used to treat ballast water and the development of safety procedures for risks to the ship and crew resulting from the treatment process Guidelines for Ballast Water Exchange in the Antarctic Treaty Area Guidance document on arrangements for responding to emergency situations involving ballast water operations 29 oktober 2012 Skibsteknisk Selskab 16

17 Port State Control and self-monitoring LITEHAUZ project 29 oktober 2012 Skibsteknisk Selskab 17

18 A breather from Germany - common standards for sampling and self-monitoring of BWMS MEPC 64/2/15 1. Agree on common standards for the control and monitoring of BWMS, on the basis of "Guidelines (G8) 2. Samples are taken and analysed in accordance with "Guidelines (G2)". The analysis results are not used as the only basis for sanctioning, but should be collected and evaluated by BLG Sub- Committee with the clear aim to develop a sampling and analysing system that delivers unambiguous results 3. Agree to exercise their discretion under article 8, paragraph 2, by furnishing to the Administration of the ship such information and evidence as may be in its possession that a violation has occurred 4. Port States would refrain from initiating proceedings in accordance with their laws on the basis of sampling the ballast water discharge alone 29 oktober 2012 Skibsteknisk Selskab 18

19 Changes underway.bwm.2/circ.28.1 recommendations for testing BWMS in different salinities (fresh water, brackish water and marine water), to ensure the systems work in their operational range of salinities;.2 recommendations for testing BWMS in cold, temperate and tropical conditions, to ensure they work in a wide range of waters;.3 recommendations for testing BWMS in different sediment loads, to ensure they work in a wide range of waters;.4 recommendations for evaluating the effects of flow rates less than the Treatment Rated Capacity (TRC) on the performance of BWMS..5 additional recommendations on improving BWM.2/Circ.33;.6 additional guidance to improve harmonization between test facilities including the use of QA/QC methodologies;.7 recommendations for dealing with, and reporting on, test failures; and.8 any other guidance to improve the application of Guidelines (G8) as deemed appropriate 29 oktober 2012 Skibsteknisk Selskab 19

20 Alternatives: Not using ballast water management systems Exceptions and Exemptions Onshore/Alongside treatment Freshwater (Potable water!) Solid ballast, ballast free, continuous flow-through ballast 29 oktober 2012 Skibsteknisk Selskab 20

21 The USCG Final Rule 2012 Entry in force March 2012 New vessels Constructed on or after 1. December 2013 Existing vessels Constructed before 1. December 2013 Type Approval Five year interim Compliance by delivery Compliance first scheduled drydocking after 1. January 2014 (1,500-5,000 m3) or 1. January 2016 USGC tested on Independent Laboratories Approval as AMS based on IMO G8 29 oktober 2012 Skibsteknisk Selskab 21

22 In conclusion BWMS are abundant and commercially available Do they work? Yes, under conditions tested How to make sure they fit your ship, your trade pattern AND function under the environment you operate in? Quiz your supplier! Expect BWMC to enter into force. 29 oktober 2012 Skibsteknisk Selskab 22
