Faults & Troubleshooting cooling/heat transfer
Failure Development, Diagnosis Logic, and Engineering Decision-Making in Marine Plants Contents 1. Purpose and Design Intent of Troubleshooting Troubleshooting exists to interrupt failure progression, not to restore perfection. Marine systems are designed to tolerate degradation. They are not designed to tolerate incorrect intervention. The goal of troubleshooting is therefore to: The most dangerous outcome is […]

Seawater Cooling
Contents 1. Purpose and Engineering Context Seawater cooling is the primary heat rejection mechanism aboard almost all seagoing vessels. Regardless of propulsion type, power density, or automation level, the ship ultimately rejects waste heat to the surrounding ocean. Every jacket water circuit, lubricating oil cooler, charge air cooler, refrigeration condenser, and hydraulic oil cooler depends—directly […]
Faults & Troubleshooting – Air & Gas Systems
Why Air and Gas Failures Kill Ships and People Air and gas systems occupy a unique position in marine engineering. They are neither fuel nor structure, yet without them engines do not start, safety systems do not function, fires cannot be controlled, and human life is placed immediately at risk. Unlike liquid systems, failures in […]
