Objectives
1. Minimize risk of introducing harmful aquatic organisms and pathogens & associated sediment from ship's ballast water.
2. Awareness of risk to environment and possibility of contamination due to discharge of ballast water.
3. Training and education in management and treatment and maintenance of appropriate records.
4. Safe, effective procedures for Ballast operations and facilitate environmentally safe disposal of ballast tank sediments.
Guidelines
Precautionary Practices-
1. Minimize Uptake in-
a. Areas known to contain potentially harmful organisms, sediment or pathogens.
b. In darkness when bottom-dwelling organisms tend to rise.
c. In shallow waters where propellers or strong currents may stir up sediment.
2. Routine cleaning of ballast tanks to remove sediments should be carried out when possible.
3. Avoid unnecessary discharge of Ballast water in ports. Plan ahead.
Ballast Water Exchange:
1. Where possible, exchange of ballast water should take place in deep water, open ocean as far as possible from shore.
2. Where above is not possible, requirements developed in regional agreements may be in operation - take note.
3. When flow through method is used, minimum three times the tank volume should be pumped through the tank.
4. When sequential method of exchange is used, all old ballast water should be pumped out until suction is lost.
5. When ballast exchange is not possible, follow other ballast exchange options approved by the state.
6. Keep Ballast Water Exchange Form ready for Port State Authority [Appendix I of IMO Res A.868(20)].
Method:
1. Sequential Exchange Method: Ballast tanks are pumped out and refilled with clean water. See safety below.
2. Flow-through Method: Ballast tanks are simultaneously filled and discharged by pumping in clean water. In this method
the tank is over flowed through air pipes and is not recommended on this vessel.
3. Discharge to reception facilities: May be provided by port State and where appropriate can be utilized.
4. New Technology treatments: Filtration, UV disinfecting, chemical or other acceptable treatments.
Safety Considerations
During Ballast exchange at sea, following should be taken into account-
1. Stability – Keep in mind free surface created during exchange operations.
2. Shear forces, Bending Moments – Permissible seagoing strength limits should never be exceeded.
3. Draft – Minimum, maximum drafts and associated trim condition will change.
4. Weather – in areas of frequent weather changes, cyclones and in heavy icing conditions take allied precautions.
a. Ship has bottom for’d strengthening for a minimum draft of 3.8m when slamming is expected.
b. Avoid exchange in freezing weather conditions as air pipes and other openings may be frozen.
c. Accretion of ice has additional effect on vessel stability.
5. Avoid over- and under-pressurization of tanks. Monitor exchange with regular soundings.
6. Contingencies such as pump failure, loss of power, deteriorating weather.
Recording and Reporting
All ballast operations to be recorded in “Ballast Operations log”.
1.
2. Details as required on Ballast reporting form for Port State Authority to be maintained.
Check Domestic laws, regulations before visiting Ports – Guide to Port Entry, etc.
