Cracked Heat Exchanger Problems in Marine Vessels

A cracked heat exchanger on a tugboat or barge isn’t just a maintenance issue — it’s a serious hazard. These cracks can allow carbon monoxide to seep into crew areas or compromise cooling performance, risking engine overheating or complete failure. In marine settings, exposure to saltwater and constant vibration increases the chances of corrosion, leakage, and material fatigue.

Signs of marine cracked heat exchanger issues include:

Decreased blower output from cabin systems

Moisture or exhaust odors near the combustion chamber

Frequent carbon monoxide detector alarms

Pressure drops or restricted flow due to buildup

At IHT Services, we use marine-grade epoxy, pressurized testing, and custom solutions to resolve minor cracks or offer complete heat exchanger replacement when needed.
