Pre-Sea Training for Merchant Navy: Complete Guide to Courses, Institutes & Fees (2026)

What Is Pre-Sea Training?

Pre-sea training is the foundational education phase of a merchant navy career — conducted entirely on land, before a candidate’s first sea posting. It’s regulated by the Directorate General of Shipping (DG Shipping), Government of India, and every course must be DG Shipping-approved to count toward a valid CDC (Continuous Discharge Certificate), INDoS number, and eventual Certificate of Competency (CoC). Depending on which department you’re aiming for — deck, engine, electrical, or ratings — pre-sea training ranges from a few months to a full four-year degree.

Once pre-sea training is complete, candidates move into on-board training (typically 6–18 months at sea as a cadet or trainee), followed by CoC exams that unlock full officer or rating status.

The Main Pre-Sea Training Pathways

India offers pre-sea training across four broad tracks, each leading to a different department on board:

1. Deck Department — BSc Nautical Science / DNS

For students who want to become navigating officers and eventually Captain:

• BSc Nautical Science: 3-year degree combining classroom study with sea training, eligibility requires 10+2 with PCM and minimum 60% aggregate
• DNS (Diploma in Nautical Science): 1-year pre-sea diploma followed by 18 months on-board training — a faster, lower-cost alternative to the full degree
• Entry exam: primarily IMU CET, plus institute-specific tests at some private academies

2. Engine Department — BTech Marine Engineering / GME

For students aiming to become marine engineers and eventually Chief Engineer:

• BTech Marine Engineering: 4-year degree, open to any 10+2 PCM student, admission via IMU CET or JEE Main
• GME (Graduate Marine Engineering): a 1-year pre-sea course for candidates who already hold a BE/BTech in mechanical or a related engineering discipline from an AICTE/UGC-recognised university — a faster bridge route into the engine department for engineering graduates

3. Electrical Department — ETO Course

For electrical/electronics engineering graduates who want the fastest entry into merchant navy at officer level:

• 4-month DG Shipping-approved pre-sea course, followed by up to 8 months on-board training as trainee ETO
• Eligibility: BE/BTech in Electrical, Electronics, or related streams with minimum 50% marks
• No IMU CET required — DG Shipping approval is the only mandatory approval for ETO institutes

4. Ratings Department — GP Rating / Marine Catering

For 10th or 12th pass candidates who want a faster, lower-cost entry into merchant navy without a full degree:

• GP Rating (General Purpose Rating): 6-month DG Shipping-approved pre-sea course; eligibility is minimum 40% aggregate in 10th standard with Science and Mathematics, plus minimum 40% in English, age 17.5–25 years
• Marine Catering course: 6-month to 1-year certificate course for candidates interested in shipboard hospitality and catering roles; eligibility is a pass in 12th standard from a recognised board
• Ratings can later progress toward officer-level qualifications through further sea time and additional courses

Pre-Sea Training Fee Comparison (All Tracks)

Fees vary significantly by institute, government vs. private status, and company sponsorship availability — treat these as indicative ranges, not fixed pricing.

Which Pre-Sea Course Should You Choose?

• Just passed 10th and want the fastest, cheapest entry? GP Rating gets you to sea in 6 months, though career progression to officer rank takes longer and requires additional exams later.
• Passed 12th with PCM and want to become a navigating officer? BSc Nautical Science (deeper academics, better long-term company preference) or DNS (faster, cheaper) depending on your budget and timeline.
• Passed 12th with PCM and want to become a marine engineer? BTech Marine Engineering is the standard 4-year route.
• Already hold a BE/BTech in mechanical engineering? GME lets you skip straight to a 1-year pre-sea bridge course instead of starting a fresh 4-year degree.
• Already hold a BE/BTech in electrical/electronics engineering? The ETO course is the fastest and most cost-effective entry point, at just 4 months of classroom training.

Top Institutes Offering Pre-Sea Training in India

Several institutes offer multiple pre-sea tracks on one campus, which is worth knowing if you want flexibility to switch specialisations or compare tracks side by side:

• Indian Maritime University (IMU) – campuses in Mumbai (T.S. Chanakya), Chennai, Kolkata, Kochi, and Visakhapatnam; the central government university offering nearly every pre-sea track at comparatively affordable fees
• Tolani Maritime Institute (TMI), Pune – BSc Nautical Science, BTech Marine Engineering, and ETO, known for strong placement records
• Samundra Institute of Maritime Studies (SIMS), Lonavala – DNS, GME, and ETO courses with strong shipping-company sponsorship ties
• Anglo-Eastern Maritime Academy (AEMA), Karjat – Deck Cadet and ETO courses with direct placement into Anglo-Eastern’s own fleet
• The Great Eastern Institute of Maritime Studies (GEIMS), Lonavala – Deck Cadet and ETO, affiliated with Great Eastern Shipping Company
• AMET University, Chennai – BTech Marine Engineering, Deck Cadet, and ETO with Maersk sponsorship track
• MERI Mumbai / MERI Kolkata – government institutes offering BTech Marine Engineering and modular/STCW courses at the most affordable end of the market

After Pre-Sea Training: What Comes Next

Completing pre-sea training doesn’t put you on a ship immediately. Every candidate must also:

1. Complete STCW (Basic Safety Training) — the mandatory safety modules (PST, FPFF, EFA, PSSR) required for every seafarer regardless of department, usually done alongside or right after pre-sea training
2. Obtain an INDoS number and CDC — official seafarer identification documents issued through DG Shipping
3. Secure a sponsorship or placement — either through the training institute or a shipping company directly
4. Complete on-board training — 6–18 months at sea depending on the track, after which candidates sit for their first Certificate of Competency (CoC) exam
