Tank temperature and pressure compatibility
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
Tank conditions are checked and agreed before transfer.
Ready on board
0 / 4 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 is a warmer receiving tank significant?
Initial vaporisation may raise tank pressure and lift a relief valve. The approved procedure must control that condition before transfer.
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 PDF says both tanks’ pressures must be reduced for a high receiving-tank temperature. It supplies no setpoints or safe method; this is not an instruction to vent or adjust pressure outside the approved LNG handling procedure.
