BALLAST WATER MANAGEMENT – News from IMO Committee –

The BWM Convention will enter into force on 8 September 2017 – one year after ratification. The convention stipulates two standards for discharged ballast water. The D-1 standard covers ballast water exchange while the D-2 standard covers ballast water treatment.

There will be a transitional period from the entry into force to the IOPP renewal survey in which ballast water exchange (requirement D-1) must be applied. After the first IOPP renewal survey, vessels will be required to meet the discharge standard D-2. The latter is most commonly met by installing an approved Ballast Water Management System (BWMS). Ships constructed after entry into force will be required to have a treatment system installed at delivery.

Moreover the IMO Marine Environment Protection Committee at its 71 session (MEPC 71) tentatively accepted an amended implementation scheme for ships to comply with the D-2 standard (treatment) under the BWM Convention.

Under the proposal:
1. New ships (constructed on or after 8 September 2017) are to comply with the D-2 standard (treatment) on or after 8 September 2017. 2. Existing ship (constructed before 8 September 2017):

having the renewal of the IOPP certificate between 8 September 2017 and 8 September 2019 (excluded) are to comply with the D-2 standard (treatment) at the following IOPP certificate renewal survey, i.e. at the second renewal survey after the entry into force date of the Convention,
having the renewal of the IOPP certificate starting from 8 September 2019, are to comply with the D-2 standard (treatment) at this renewal survey, i.e. at the first renewal survey after the entry into force date of the Convention.
