The engine room never lies, but it often speaks in riddles. 🚢⚓ There are engine room problems that announce themselves with smoke and alarms. Then there are the "quiet" ones—like a slow, unexplained cooling water temperature rise. It starts as a 3-degree drift. Then 5. Everything looks normal, but your gut tells you something is slipping. When the rhythm of the plant changes, I stop guessing and start looking at the Four Pillars of Cooling Failure: 1️⃣ Flow: Is the water actually moving, or is your pump just "spinning wheels"? 2️⃣ Heat Transfer: Is that Plate Heat Exchanger (PHE) becoming an insulator? 3️⃣ Control: Is your 3-way valve lying to you? 4️⃣ Indication: Is the engine actually hot, or is the sensor just having a bad day? A professional watchkeeper doesn't just "adjust the bypass" and hope for the best. They follow the heat until they find the truth. I’ve broken down the full troubleshooting sequence in my latest article. 🔗 #MarineEngineering #Shipping #MarineEngineer #EngineRoom #TechnicalManagement #Maritime
