A 3-year undergraduate degree programme approved by DG Shipping and IMU that prepares you to become a Deck Officer in the Merchant Navy. Learn about eligibility, IMU-CET, top colleges, career progression, salary, and FAQs.
B.Sc. Nautical Science is a 3-year undergraduate degree programme designed for students who aspire to become Deck Officers in the Merchant Navy. The programme combines academic learning, simulator-based training, practical maritime education and professional development to prepare cadets for a career in navigation and ship operations.
The course is approved by the Directorate General of Shipping (DG Shipping) and is offered by the Indian Maritime University (IMU) and other DG Shipping-approved Maritime Training Institutes (MTIs). It follows the standards prescribed under the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW).
After successfully completing the degree, graduates are required to complete 12 months of onboard sea service as a Deck Cadet. Upon completing the prescribed sea service and fulfilling all applicable DG Shipping requirements, they become eligible to proceed towards the Second Mate (Foreign Going) Certificate of Competency (CoC) assessment and examination.
Unlike the One-Year Diploma in Nautical Science (DNS) pathway, B.Sc. Nautical Science graduates are exempt from the mandatory Second Mate Function (SFU) Course, as the required academic and professional competencies are already covered during the three-year degree programme. This is one of the biggest advantages of pursuing B.Sc. Nautical Science.

Merchant Navy salaries are paid exclusively during active sailing contracts and are traditionally benchmarked in US Dollars (USD). The actual take-home pay is dictated by rank seniority, company profile, and the technical complexity of the vessel.
| Rank Seniority | Monthly Wage (USD) | Approx. Monthly Income (INR)* |
|---|---|---|
| Deck Cadet | $500 – $1,200 | ₹40,000 – ₹1,00,000 |
| Third Officer | $3,200 – $5,500 | ₹2.6 Lakh – ₹4.5 Lakh |
| Second Officer | $4,500 – $7,200 | ₹3.7 Lakh – ₹6.0 Lakh |
| Chief Officer (Dry) | $8,500 – $12,500 | ₹7.0 Lakh – ₹10.3 Lakh |
| Chief Officer (Wet) | $11,000 – $14,500 | ₹9.1 Lakh – ₹12.0 Lakh |
| Master / Captain (Dry) | $11,000 – $15,000 | ₹9.1 Lakh – ₹12.4 Lakh |
| Master / Captain (Wet) | $15,000 – $21,000+ | ₹12.4 Lakh – ₹17.4 Lakh+ |
*INR values fluctuate relative to active exchange rates. Wages are paid strictly for the duration of the onboard contract; no basic salary is typically paid during vacation months.
Under Section 6(1) of the Indian Income Tax Act, salaries earned by Indian seafarers are 100% exempt from income tax only if the candidate maintains valid Non-Resident Indian (NRI) status for the financial year.
To secure this tax-free classification, your continuous or cumulative stay outside India must total 182 days or more within a single financial year (calculated strictly using entry and exit stamps on your CDC and passport). If your sailing contracts total fewer than 182 days, your entire annual earnings are subjected to regular domestic tax slabs.
A B.Sc. Nautical Science qualification opens two distinct professional lifecycles: deep-sea commercial navigation and corporate maritime management ashore.
After securing Chief Mate or Master Mariner credentials:
Do not enter this industry treating the dollar salary as easy money. Shipping companies pay top-of-market wages because they expect absolute psychological resilience, high-tier technological competence, and unwavering sobriety. Focus your early years on mastering automated navigation bridges and clearing your CoC papers at the very first opportunity.
Responsibilities increase exponentially with rank. While a Deck Cadet learns through observation, a Captain bears absolute legal and financial accountability for the vessel, cargo, crew, and environmental compliance.
| Certificate | When Required | Issued By |
|---|---|---|
| Second Mate (FG) CoC | After 12 months Deck Cadet sea service | MMD / DG Shipping |
| Chief Mate (FG) CoC | After 18 months watchkeeping service + courses | MMD / DG Shipping |
| Master (FG) CoC | After 12 months management service + ASM | MMD / DG Shipping |
B.Sc. Nautical Science graduates are 100% exempt from the 4-month Second Mate Function (SFU) Course. Because the academic curriculum covers all theoretical competencies required by the STCW convention, you bypass post-sea classrooms entirely after your 12 months of sea time and apply straight for your MMD assessment.
Keep your CDC, passport, and CoC documents updated at all times. Shipping companies and port state control authorities will not permit sign-on if any certification is expired or invalid. Set calendar reminders 90 days before every expiry.

Visit the official DG Shipping e-Governance portal and cross-check the institute's live status on the approved MTI master ledger. Ensure the college holds a live CIP grade of A1 or A2.
A minimum of 12 months of approved onboard sea service. During this time, you must systematically complete your DGS Training and Assessment Record Book (TAR Book).
No. This is a major structural advantage. Because the academic curriculum covers all STCW theoretical competencies, B.Sc. graduates are 100% exempt from the 4-month SFU Course. After 12 months sea time, you apply straight for MMD assessment.
Yes. The program provides a direct roadmap to the top of the merchant fleet hierarchy: Deck Cadet → Third Officer → Second Officer → Chief Officer → Master / Captain.
No, it is strictly compulsory. As mandated by DG Shipping, all nautical training programs are 100% residential with uniform codes, mandatory PT, and high semi-military discipline.
A fresh Deck Cadet earns $500–$1,200 USD/month (approx. ₹40,000–₹1,00,000+). This income is 100% tax-free in India only if you maintain NRI status by staying outside India for 182+ days in a financial year.
Anglo-Eastern, Synergy Marine, Fleet Management, Executive Ship Management, MSC, Maersk Line, MOL, Seaspan, V.Group, and The Great Eastern Shipping Company.
Both lead to the same destination (Captain), but suit different profiles. B.Sc. offers a recognised Bachelor's Degree, only 12 months sea time, SFU exemption, and campus placement recruitment. DNS requires pre-admission sponsorship, 18 months sea time, and 4 months of post-sea SFU classes. Choose B.Sc. if you want a university degree and are confident in campus placements.
Yes, absolutely. Female candidates are highly encouraged to apply provided they satisfy all standard academic and DGS medical requirements. IMU offers substantial fee concessions to female students, and global ship owners actively run dedicated recruitment tracks for female deck cadets.
Yes. The Indian maritime educational framework is strictly aligned with the IMO's STCW Convention standards. Your Indian CoC allows you to command ships flying almost any major international flag worldwide.
