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 […]
