Cargo-manifold arrangements
What is being checked
The inspector is checking whether cargo-manifold valves, flanges, blanks, drains, supports and identification matches the approved arrangement, is physically ready, is tested through its complete operating path and is understood by responsible personnel.

0/6 completePractice questions
Answer aloud, then open the preparation point.
1What is the purpose and operating limit of cargo-manifold valves, flanges, blanks, drains, supports and identification?
Explain the protection provided by line identity, valve and blank position, pressure rating, reducers, gauges, drains, spill containment, lifting and presentation flange, including the condition that requires intervention.
2How is the complete operating path tested?
Use the approved safe test method to prove valve operation, leak test, gauge verification, blank integrity, drain control and line-marking check, including the final alarm, trip, movement or indication.
3What happens if the equipment is unavailable?
Notify the Master and terminal as applicable, stop or restrict the affected operation, establish approved compensating controls and obtain repair or formal authority.
4Show the latest maintenance and defect history.
Match the physical identity to PMS, calibration or service records and verify that any temporary control has been closed.
5Which indication proves the equipment is in its safe condition?
Identify the local and remote indication, its source, alarm set point and how a false or frozen signal would be detected.
Where an observation may arise
The fitted system, drawing, manual or certificate did not agree.
Inspection identified wrong line identification, passing valve, damaged flange, missing bolt, open drain, low-rated component, unsupported reducer or ineffective containment.
Records did not prove valve operation, leak test, gauge verification, blank integrity, drain control and line-marking check through the complete operating path.
An alarm, trip, interlock or indication was isolated, incorrect, overdue for test or not understood.
PMS, calibration, service or repair evidence was missing, overdue or not traceable to the item.
Responsible personnel could not explain line identity, valve and blank position, pressure rating, reducers, gauges, drains, spill containment, lifting and presentation flange, operating limitations or failure response.
Master's practical note
Trace one signal or flow path from the field device to the CCR or ECR and back to the final protective action. A successful local test alone may not prove the full system.
Equipment boundary and references
Equipment boundary: Use approved test modes and maker instructions. Do not bypass an interlock, release cargo or defeat protection merely to satisfy an inspection demonstration.
