Cargo Tank Pressure and Temperature Monitoring Log

Inspection template for monitoring cargo tank pressure, multi-point cargo temperatures, and boil-off conditions against the Maximum Allowable Relief Valve Setting (MARVS), with corrective action tracking for out-of-range readings.

Inspection Details

• Inspection date and time recorded
• Tank or trailer identification recorded
• Product name and cargo class recorded
• Inspector identified as competent person or authorized operator
• Inspection phase selected

Pressure Monitoring

• Current tank pressure recorded
• Applicable MARVS recorded
• Tank pressure remains below MARVS
• Pressure trend is stable or within expected operating range
• Relief valve discharge, venting, or abnormal noise observed

Temperature Monitoring

• Top cargo temperature recorded
• Middle cargo temperature recorded
• Bottom cargo temperature recorded
• Temperature differential between measurement points is within expected limits
• Temperature trend indicates warming, stratification, or localized hot spot

Boil-Off and Vapor Control

• Boil-off rate recorded
• Boil-off remains within acceptable operating limits
• Vapor return, venting, or pressure management controls are in service
• Any product loss, visible vapor release, or unexplained pressure increase observed

Corrective Actions and Attestation

• Corrective actions documented for any out-of-range condition
• Supervisor, terminal operator, or emergency contact notified when required
• Inspector signature
