Why Electrical Engineering Gives You a Good Shot
Electrical engineers already know circuits, power systems, control, electronics — skills directly useful on ships, especially in the ETO (Electro-Technical Officer) role. Rather than starting from scratch, you adapt your learning to marine equipment: shipboard power, navigation electronics, automation, communication systems.
You can join the merchant navy after electrical engineering by taking the ETO course (about 4 months), then doing shipboard training. So the route is shorter and more specific than doing a full marine engineering degree.

What Is the ETO Course?
ETO = Electro-Technical Officer. On a ship, this person is responsible for all electrical / electronic / automation systems (communications, control, navigation, power).
Key features:
- It’s a pre-sea course (classroom + labs).
- Duration is typically 4 months residential training.
- After that, you go for 8 months shipboard / on-board training as a trainee ETO.
- After successful training and passing the required exams (Certificate of Competency, per DG Shipping), you become a full ETO onboard.
Eligibility & Requirements
To enroll for ETO after electrical engineering, you must satisfy academics, age, and medical standards. Here’s what I found:
Academic requirements
- You should hold a Degree (BE / BTech) in Electrical Engineering, Electronics Engineering, Electrical & Electronics Engineering (EEE), Electronics & Telecommunication (ECE), or Electronics & Instrumentation or equivalent.
- Some colleges demand minimum marks (for example, 65% aggregate in degree) before you can apply to their ETO course. AEMA, for instance, requires 65% in degree.
- Also, in your 10th / 12th (or equivalent), you must have studied Physics, Chemistry, Mathematics (PCM).
- English: you often must have secured a minimum percentage (like 50%) in English in 10th or 12th.
Age & Other Conditions
- Many institutes cap the maximum age (e.g. AEMA says max age 28).
- You must be medically fit, including eyesight (vision 6/12 or acceptable standards), and no color blindness.
- Some require English in degree medium or marks if you didn’t get English earlier.
If you meet those, you can apply to ETO courses.
Selection Process & Steps
Here’s how the process usually goes:
- Application / Entrance Test: Many colleges conduct their own tests for ETO admission.
- Panel Interview: Shortlisted candidates may be called for an interview.
- Medical Examination: Must clear DG Shipping approved medical checks.
- Pre-sea Training: If selected, do the 4 months classroom/lab ETO training.
- Shipboard Training: After finishing classroom, go onboard for 8 months as trainee ETO.
- Certificate of Competency / Exam: After training, appear for required exams (CoC) to qualify as ETO.
- Begin ETO career: Once certified, you serve as ETO on ships, maintaining all electrical / electronic systems.
What Does an ETO Do Onboard?
Understanding the role helps you see whether this suits you:
- The Electro-Technical Officer is responsible for all electrical, electronic, automation, control systems onboard: navigation aids, communication, power systems, sensors, instrumentation.
- Unlike traditional engine officers, the ETO usually does not take engine room watches. They are on ad hoc shift or standby duty, servicing electrical systems, diagnostics, troubleshooting.
- ETO reports to the Chief Engineer or head of the engineering department, but is a specialized function focusing on the ship’s “brains and nervous system” (electronics).
The role demands a blend of electrical knowledge, adaptability, prompt decision making, and ability to maintain critical systems under pressure.

Best ETO Colleges / Institutes
Which colleges offer DG-approved ETO courses?
- AEMA (Anglo Eastern Maritime Academy)
- SI MS (Samundra Institute of Maritime Studies)
- HIMT College
- IMI (International Maritime Institute)
- GEIMS
- Euro Tech Maritime Academy.
Before finalizing, always cross-check their DG Shipping approval status, fees, current placement records, and ship onboard training capacity.

Pros & Challenges of Choosing the ETO Route
Pros
- Faster route compared to a full marine engineering degree: 4 months training + 8 months sea time is relatively quick.
- Use your electrical engineering background, so less content is foreign to you.
- ETO has niche importance: modern ships rely heavily on electronics and automation, making ETOs increasingly essential.
- Good global mobility: ETOs are recognized under STCW (Section A-III/6) code worldwide.
Challenges
- Limited seats in reputable institutes; competition is strong.
- Some institutes may delay actual ship posting or have weak ship tie-ups.
- The workload and stress are high: you must maintain critical systems continuously, often in challenging conditions.
- Technology changes fast: you must keep updating yourself.
If your institute or course loses DG approval, your qualification might lose weight.
