DGMA MEO & ETO Preparatory Course 2026: Best Guide

The Directorate General of Maritime Administration (DGMA) has issued EAC Branch Circular No. 49 of 2026, establishing mandatory MEO & ETO Preparatory Course rules and revised training frameworks for Marine Engineer Officers (MEO) and Electro-Technical Officers (ETO) appearing for Certificate of Competency (CoC) examinations on the official DGMA portal.

Whether you are preparing for your MEO Class-IV, MEO Class-II, MEO Class-I, or ETO CoC examinations, this best guide provides a complete breakdown of the mandatory MEO & ETO Preparatory Course structure, revised course durations, expanded technical syllabi, practical lab requirements, and compliance guidelines at accredited recognized maritime training institute centers across India.

Key Updates Under DGMA MEO & ETO Preparatory Course Circular No. 49

Following feedback from CoC examination boards, maritime training institutes, ship management companies, and sailing engineering officers, DGMA conducted a comprehensive review of candidate examination performance.

Addressing Candidate Performance Gaps

The technical committee observed that entry-level engineering and electro-technical candidates frequently struggled during CoC written and oral examinations due to several factors:

• Post-Sea Academic Disconnect: Candidates appearing for initial CoC examinations after completing mandatory sea service often lacked structured academic revision offered by the MEO & ETO Preparatory Course.
• Over-Reliance on Rote Learning: Memorizing static question banks failed candidates during in-depth oral assessments, where examiners test fundamental engineering comprehension taught in the revised MEO & ETO Preparatory Course.
• Modern Technology Gaps: Emerging developments in dual-fuel engines, high-voltage systems, shipboard automation, cybersecurity, and environmental decarbonization were incorporated into the updated MEO & ETO Preparatory Course curriculum.
• Need for Standardized STCW Compliance: Aligning shore-based preparatory training under the MEO & ETO Preparatory Course with updated STCW 1978 Regulation I/6, Regulation I/11, Regulation III/1, Regulation III/2, and Regulation III/6 requirements.

To bridge the gap between practical sailing experience and CoC competence standards, DGMA has introduced mandatory structured preparatory courses for MEO Class-IV and ETO grades, while streamlining the MEO Class-II course duration. Candidates completing pre-sea training can refer to our detailed GP Rating Course Guide to see how structured pre-sea preparation lays the groundwork for officer promotions. Enrolling in an official MEO & ETO Preparatory Course batch ensures full compliance before booking exam dates.
