ERS/ESD surge-pressure 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
Overpressure protection is documented or addressed by design.
Ready on board
0 / 3 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.
1Does an N/A answer mean surge protection is unnecessary?
No. The PDF permits N/A where that overpressure has been considered by the transfer-system design.
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
Explicit source instruction: select N/A if the transfer system is designed to consider overpressurisation due to surge pressure on ERS or ESD activation. This is a design-based condition, not a missing-document exemption.
