Electro Technical Officer (ETO) Responsibilities in Merchant Navy: Complete Job Role & Duties Explained
A Electro Technical Officer (ETO) is the electrical backbone of a merchant ship, responsible for handling power systems, automation, navigation electronics, and emergency repairs onboard. Learn full ETO responsibilities, duties, eligibility, syllabus, salary, and career scope in this detailed guide.
Introduction
If you ever picture a giant ship battling rough seas, lights flickering due to a sudden power surge… there’s one person everyone runs to — the Electro Technical Officer (ETO). And trust me, without an Electro Technical Officer (ETO), even the most advanced ship becomes helpless.
People often think engineers only fix engines, but the truth is, ships today run on electronics, automation, high-tech navigation systems, and control panels — and the one who handles all this is the ETO.
With over 50,000 merchant vessels worldwide and increasing digitalization, the demand for skilled Electro Technical Officers has shot up by 15% since 2020 (IMO data).
This blog will explain every part of the job — ETO duties, daily responsibilities, skills, salary, course details, eligibility, exams, challenges, and growth opportunities, all in a simple, conversational way.
Let’s begin this journey toward understanding the real life of the ETO onboard.
Who is an Electro Technical Officer (ETO)?
An Electro Technical Officer (ETO) is the electrical and electronics expert onboard a ship. Their job is to ensure everything that runs on power, chips, wires, and digital systems works smoothly 24×7.
They are basically the bridge between ship operations and electrical/electronic systems.
Ships today run on technology, and ETOs keep that technology alive.
Qualifications Needed
To work as an Electro Technical Officer in Merchant Navy, seafarers must meet these qualifications:
- STCW ETO Certification
- Diploma or Degree in Electrical, Electronics, or EEE
- Age above 21
- Basic Safety Training
- Valid Medical Fitness Certificate
- Some sea-time (varies by company)
A Marine Insight 2024 report said that 70% of new ETO hires now come with full electrical engineering degrees.
⚡ Difference Between ETO & Other Engineering Roles
Many students get confused between ETO, electricians, and marine engineers. Here’s the simplest explanation:
- Marine Engineers → Handle engines, boilers, pumps, propulsion
- Electricians → Do basic wiring and electrical repairs
- ETO → Handles automation, navigation electronics, control systems, IT systems, power distribution, radar, GPS, communication, alarms, PLC, and advanced circuitry
A real example:
If the navigation radar stops during a storm — the ETO fixes it.
If the main engine overheats — the marine engineer handles it.
As Capt. Rajesh Sharma says:
“ETOs keep the ship’s brain alive.”
⚙️ Core Daily Responsibilities of an Electro Technical Officer (ETO)
Now let’s break down real onboard responsibilities.
- Electrical System Maintenance
Every morning, the ETO does routine rounds to ensure everything is running perfectly.
Daily Tasks Include:
- Checking generators & emergency generator
- Inspecting main switchboard
- Testing batteries & UPS
- Monitoring power load
- Checking lighting panels
- Inspecting electric cables
Takeaway:
If you follow a checklist properly, 90% failures can be avoided.
2. Troubleshooting & Repairs
This is where the real pressure lies. When something breaks onboard, everyone waits for the ETO to fix it — fast.
Common Emergencies ETO Handles:
- Power blackouts
- Navigation failure
- Communication breakdown
- Engine automation failure
- Switchboard trips
- Alarm system malfunction
Example:
In a 2023 Maersk vessel blackout, ETOs restored full power in 2 hours, preventing a potential collision.
ETOs must master:
- Multimeter
- PLC Programming
- Fault-finding techniques
- Circuit reading
🔧 Technical Duties & Expertise
Ships today are fully automated. ETOs handle systems that even mechanical engineers don’t touch.
Navigation & Communication Systems
ETOs are responsible for:
90% of major incidents happen due to electronic failures (Allianz Safety Report 2025).
Key Duties:
- Calibrating navigation systems
- Updating software
- Backing up voyage data
- Checking communication signal quality
Automation & Control Systems
Ships depend heavily on automation.
ETOs monitor:
- PLC panels
- Fire detection systems
- Engine automation
- Bilge alarms
- Ballast automation
- Cargo control systems
ETO trainer Maria Lopez says:
“Automation reduces human error by almost 40%.”
🚨 Safety Protocols & Emergency Handling
ETOs play a crucial role in ship safety drills.
Key Safety Responsibilities:
- Testing fire detectors
- Running emergency shutdown simulations
- Checking battery backup
- Managing LOTO (Lock Out Tag Out)
- Ensuring PPE compliance
Emergency Handling Example:
In a 2024 storm near the Red Sea, an ETO restored partial power by rewiring emergency circuits. That saved the vessel.
