USCG NMC UFIV01
The Chief Engineer UFIV (NMC code UFIV01) is a U.S. Coast Guard engineer officer endorsement for uninspected fishing industry vessels. Candidates qualify under 46 CFR 11.530 with four years of engineroom service, including one year as Assistant Engineer Officer or equivalent, and two-thirds of required service on motor vessels. The exam is modular multiple choice: Q694 Motor Plants (50), Q696 Engineering Safety & Environmental Protection (50), and Q697 General Subjects (50)—150 questions total, 70% pass each module. Typical original lower-level fees are about $100 evaluation + $95 exam + $45 issuance ($240). Content emphasizes diesel motor plants and casualty control, engineering safety and MARPOL/OPA 90 environmental rules, and general auxiliaries with management-level decision making on fishing vessels.
