Cryogenic spill trays and hull protection
Applicability: Section 7B applies where equipment, machinery or a system on board uses LNG fuel. Apply the vessel-specific conditions in this entry.
What is being checked
Spill protection prevents LNG contact with hull steel.
Ready on board
0 / 5 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.
1Why must a tray outlet avoid the hull?
Contact between very cold LNG and mild steel can cause brittle failure; the source calls for discharge away from hull contact.
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 final paragraph is quoted from IGC cargo-transfer provisions although this section concerns fuel bunkering. Use the applicable approved fuel-system arrangement. Entry 7B.22 also describes water curtains conditionally; this guide does not infer an exemption or universal retrofit instruction.
