Class society ABS has summarised the proposed amended implementation scheme for IMO’s Ballast Water Management Convention (BWMC) that was discussed earlier this week at the Marine Environment Protection Committee (MEPC 71).
If the scheme is approved during the meeting’s final deliberations tomorrow (7 July), it will be circulated to member states for adoption during MEPC 72, scheduled to be held from 9-13 April, 2018.
In its interim briefing, ABS explains that, under the proposal, ships constructed on or after 8 September 2017 (the date that the BWMC will enter into force) are to comply with the D-2 water discharge standard on or after that date.
Existing ships – constructed before that date – are to comply with the D-2 standard at the first renewal survey for their International Oil Pollution Prevention Certificate (which is required under Marpol) completed on or after:
ABS added that if the survey per Reg B-3/10.1.2 is not completed, “then compliance with the D-2 standard is required at the second Marpol IOPPC renewal survey after 8 September 2017, only if the first Marpol IOPPC renewal survey after 8 September 2017 is completed prior to 8 September 2019 and a Marpol IOPPC renewal survey was not completed on or after 8 September 2014 but prior to 8 September 2017 (Reg B-3/10.2).”
For ships constructed before 8 September 2017 and which are not subject to the Marpol IOPPC renewal survey, compliance with the D-2 standard is required not later than 8 September 2024 (Reg B-3/5), its summary ended.
It has prepared a diagram illustrating the various timetables, included in the briefing and reproduced at the head of this news item. The briefing can be read in full here.
