Reduce the risk of introducing and propagating aquatic invasive organisms and pathogens associated with ballast water discharges and biofouling.
This indicator does not apply to companies operating ships which pose no risk of introducing or propagating aquatic invasive species through the intermediary of ballast water (e.g. ships which do not use ballast, short haul ferries, barges, etc.).
See below the criteria each ship owner has to fulfill to achieve each level of performance.
Monitoring of regulations.
2.1. Minimize or whenever possible avoid uptake of ballast water in the following conditions:
Note: These measures should include any specific regulations applicable in ports or transit areas.
2.2. Uptake only the minimum amount of ballast water required to safely depart the dock, and complete ballasting operations in deeper waters (while always ensuring the safety of the vessel).
2.3. Develop and implement preventive voluntary measures if EU national / EU port authorities determine that a harmful species has established itself in a particular port.
2.4. Periodically inspect vessels’ hulls including niche areas, such as sea chests, propeller thrusters, keels, rudders, and dry dock support strips.
Note: Refer to 2011 IMO Biofouling Guidelines Sections 1.4, 7.2, 7.3, and 7.4. A copy can be found in the Members section of the Green Marine website.
2.5. If needed, remove biofouling organisms from the hull, propellers, stern tube, sea chests, and other wetted portions of a vessel.
Note: Cleaning is suggested if biofouling covers over 15% of the wetted surfaces. At 15% coverage, the vessel is considered extensively fouled. Diagrams to help estimate percent coverage can be found in the Members section of the Green Marine website.
2.6. For each vessel, keep a record book on details of all inspections and biofouling management measures undertaken on the ship.
Note: A template of such a record book can be found in the Members section of the Green Marine website.
3.1. Maintain a Ballast Water Management plan and Biofouling Management plan for each vessel which includes all the best practices required to achieve Level 2. Have a policy to support scientific research (3.2).
Note: A Biofouling Management plan template can be found in the Members section of the Green Marine website.
3.2. Support scientific research on ballast water or biofouling by providing access to ships for sampling by governmental and research groups.
Note: It is not necessary to actively participate in the research program in order to fulfill this criterion.
3.3. Complete and maintain an annual inventory to evaluate the amount of ballast water taken and discharged by the company’s ships by origin/destination.
Note: See Annex 1-A.
3.4. Produce an annual report showing any cases where the Port State Control issues a fine or warning for improper ballast exchange or reporting. For such cases, include root cause(s) and preventive action(s) taken.
3.5. Within dry-docking specifications, select coating with effective coating lifespan in line with schedule for next dry-docking and anticipating operational wear, such as contact with lock walls or abrasive cleaning.
Note: The effective coating lifespan is determined by the manufacturer based on the vessel-specific application scheme (e.g. coating thickness); it is the age of an anti-fouling coating after which the coating is no longer expected to satisfactorily prevent or deter the attachment and growth of biofouling organisms.
Fulfill one of the following 3 criteria:
4.1. Actively participate in the development and trial of a ballast water treatment method (mechanical, physical, or chemical) on one or several of the company’s vessels.
4.2. Actively participate in research on reducing the risk of AIS introduction and spread associated with ballast water operations and discharges.
4.3. Actively participate in research for ecofriendly biofouling paints and antifouling systems and on reducing the risk of AIS via biofouling, for example – autonomous underwater cleaning or underwater cleaning reclamation (vacuum or other control technologies).
Note: Active participation is defined as the provision of support by the company, whether through financial means, human resources or equipment and can include an experimental shipboard trial.
5.1. Install and use a ballast water treatment system on one or several of the company’s vessels. And, for each installed and in-use system, adopt contingency measures, as per MEPC 71/WP.9 Annex 4.
Note: See “Links to Ballast water Regulations” document in the Members section of the Green Marine website for reference and links to regulations.
