Ammonia bunker plan and risk assessment
Applicability: Section 7D applies where equipment, machinery or a system on board uses ammonia fuel. Apply the vessel-specific conditions in this entry.
What is being checked
The bunker plan and SMS address ammonia-specific risks.
Ready on board
0 / 8 checkedCheck the vessel’s actual procedures, equipment and records against these points from RISQ 3.2.
Practice questions
Preparation prompts derived from this entry, not an official inspector interview script.
1Can the loading limit be taken as a fixed percentage at any tank temperature?
No. The source’s 98% provision is expressed at a reference temperature; use the vessel’s approved loading-limit calculation and conditions.
2What happens to risks that cannot be eliminated?
They require documented mitigation, with the source calling for Administration satisfaction.
Where a finding may arise
Missing evidence or defects inconsistent with the checks above may prevent a satisfactory answer. These are preparation concerns derived from the question, not explicit additional finding criteria or reported past observations.
Past observations for practice
Anonymised reports, manually reviewed before publication. These are reported experiences, not additional inspection requirements.
No reviewed observations have been added for this entry.
Share an observation for private review
Remove vessel, company and inspector names, report numbers, exact dates and confidential information. Do not paste a complete inspection report.
Source clarification
The source quotes a 98%-full equivalent at the defined reference temperature and a special-consideration provision capped at 95% where insulation/location make external-fire heating very unlikely. These statements must not be treated as interchangeable gauge limits or permission to select the larger figure. The entry draws on the PDF’s ClassNK, ABS and MSC.1/Circ.1687 citations.
