Electrical isolation and hose-support limits
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
Hoses have controlled electrical paths and suitable supports.
Ready on board
0 / 6 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 installing an insulating flange at both ends a concern?
The source warns this can leave the hose electrically isolated and permit electrostatic build-up.
2What hose-support limits must be documented?
Minimum and maximum supported hose lengths and diameters, with the design supporting relevant loads and maintaining the maker’s bend radius.
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.
Editorial background reading. Inspection requirements remain those of the cited RISQ entry.
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
Location conflict: this paragraph specifies the bunker-ship manifold, while 7B.17 specifies the receiving side. Preserve the approved single-insulation arrangement and resolve the discrepancy through the approved procedure; do not add a second flange to satisfy both wordings.
