VIQ 7 / 8.18 Are the Cargo and ballast system valves in good order and is there evidence of regular testing? Valve closing times should be periodically checked with manufacturers data to ensure they do not create potential surge pressures in the system when closed.
The test required above, should it be done for cargo valves ONLY or also for ballast system valves ? since the question is speaking about both cargo and ballast valves.
Both cargo and ballast valves should periodically be checked and appropriate checklists maintained.
