Practice questions
Preparation prompts derived from this entry, not an official inspector interview script.
1What does repeated high TRO during discharge suggest?
Possible ineffective neutralisation. The source lists metering-pump, neutraliser preparation/quantity, TRO sampling/reagent and valve-arrangement problems.
2Can a failed system simply be bypassed to finish deballasting?
No. The PDF calls for contacting management first, treating bypass as a last resort, addressing environmental risk and following the failure/notification arrangements.
3What distinguishes an electronic BWRB from an unapproved electronic log?
The ship carries the required ship-specific declaration for the approved replacement system.
Where a finding may arise
Missing evidence, defects or operation inconsistent with the arrangements described above may prevent a satisfactory answer. These are preparation concerns derived from the question, not reported past observations.

Source clarification
The PDF makes broad statements about “all ships” and the September 2024 D-2 milestone. This entry does not use those statements to remove vessel-specific Convention applicability, approved arrangements or exemptions. Exchange is not presented as automatic permission to bypass required treatment.
