Main Engine Exhaust Gas Temperature Monitoring Restored – Khalid Port, Sharjah

The vessel’s EGT monitoring system was operating with multiple critical deficiencies

Open channels, failed sensing elements, and obsolete OEM sensors with non-standard specifications, no longer supported or available.

Technical Intervention

• Reverse-engineered existing sensor specifications and input requirements
• Designed and supplied custom-built temperature sensors (RTD/Thermocouple based on channel configuration)
• Fabricated compatible thermowells considering insertion length, process connection, and material grade
• Ensured signal compatibility with AMS input modules (mV / 4–20 mA as applicable)

System Reinstatement

• Re-established all temperature measurement channels across engine cylinders
• Loop checking, insulation resistance verification, and continuity testing completed
• Calibration carried out via AMS with channel-wise scaling and linearization
• Alarm setpoints verified for high-temperature and deviation logic

Performance Outcome

• Accurate real-time EGT monitoring across all units
• Restored alarm integrity for early fault detection (overheating, injector issues, imbalance)
• Improved diagnostic capability for cylinder performance and load distribution
• Compliance aligned with class and safety monitoring requirements

Engineering Value

Reinstating a fully functional EGT monitoring system is essential for preventing thermal overload, identifying combustion inefficiencies, and ensuring safe engine operation under varying load conditions.
