Cargo Tank Closed Gauging Verification

Inspection template to verify cargo tank closed gauging is used in accordance with the IGC Code and that no slip-tube or restricted gauging arrangement is releasing LPG to atmosphere.

Inspection Scope and Vessel Identification

• Cargo tank identification recorded
  Record the tank number, cargo system identifier, and inspection location.
• Cargo product verified as LPG or other liquefied gas requiring closed gauging
  Confirm the cargo being inspected requires closed gauging controls under the applicable cargo system rules.
• Inspection reference documents available
  Verify the applicable cargo system procedure, IGC Code reference, and shipboard operating instructions are available to the inspector.
• Inspector notes on operating condition
  Document whether the tank is in service, idle, inerted, or under maintenance at the time of inspection.

Closed Gauging Arrangement

• Closed gauging device installed and in use
  Confirm the tank is equipped with and using a closed gauging arrangement for level measurement.
• No slip-tube gauging arrangement observed
  Verify no slip-tube arrangement is being used in a manner that would release LPG to atmosphere.
• No restricted gauging arrangement releasing vapor to atmosphere
  Confirm restricted gauging, if present, does not create an open release path to atmosphere during measurement.
• Gauging interface appears sealed and intact
  Inspect the gauging point, seals, fittings, and covers for visible damage, leakage, or missing components.
• Evidence of vapor release during gauging
  Check for visible vapor release, odor, frosting, or other signs of product escaping during measurement.

Operational Controls and Safety Practices

• Procedure requires closed gauging only
  Confirm the operating procedure prohibits open gauging or any method that vents LPG to atmosphere.
• PPE appropriate for LPG gauging task available and used
  Verify required PPE is available and in use for the task, including eye and face protection as applicable to the site procedure.
• Area around gauging point controlled during measurement
  Confirm the area is controlled to prevent ignition sources, unnecessary exposure, or unauthorized access during gauging.
• Any abnormal condition documented
  Record leaks, damaged fittings, procedural deviations, or other non-conformances observed during the inspection.

Compliance Evidence and Corrective Action

• Photo evidence captured for non-conformance or deficiency
  Attach photos when a deficiency, leak, damaged seal, or prohibited gauging arrangement is observed.
• Reference to applicable standard or procedure
  Record the applicable IGC Code reference, company procedure, or terminal/vessel instruction used for the inspection.
• Corrective action required for any failed critical item
  Confirm corrective action has been initiated for any failed critical item, including isolation, repair, or operational توقف as required by procedure.
• Inspector signature
  Inspector attestation that the closed gauging verification was completed accurately.
