Difference Between Diploma in Nautical Science (DNS) & BSc in Nautical Science
— A Clear Guide for Aspiring Mariners
If you’re an aspiring deck officer in the Merchant Navy, you’ve probably come across two major pathways: Diploma in Nautical Science (DNS) and BSc in Nautical Science. While both lead toward the same goal — becoming a deck officer — the routes, duration, and approach differ significantly.
Let’s break down the differences so you can make an informed choice.
📘 1. Course Duration
- DNS: 1 year diploma course followed by 18 months of sailing (onboard training), leading to a 2nd Mate exam.
- BSc Nautical Science: 3 years full-time degree course in college, followed by 12 months of sea training.
👉 DNS is shorter on campus but demands early commitment to sea life.
🎓 2. Academic Qualification
- DNS: Awarded as a Diploma; later eligible to convert into BSc Nautical Science via IGNOU after sea time and exams.
- BSc: You directly get a Bachelor’s Degree in Nautical Science.
👉 If you want a conventional degree upfront, BSc might suit you better.
⚙️ 3. Sponsorship & Placement
- DNS: Requires sponsorship before joining the course. This means you must clear company-specific sponsorship exams/interviews before admission.
- BSc: You may or may not be sponsored at admission. Placements are usually facilitated during or after the course.
👉 DNS gives job security upfront, but competition for sponsorship is tougher.
🧭 4. Financial Investment
- DNS: Shorter course duration means lower initial fees, but you must manage expenses during sea training.
- BSc: Higher upfront fees due to 3 years of classroom education, but some students get scholarships or loans.
👉 DNS is cost-effective initially, while BSc has a more spread-out cost.
⛵ 5. Career Progression
Both DNS and BSc routes ultimately lead to the same Merchant Navy career path:
Cadet → 3rd Officer → 2nd Officer → Chief Officer → Captain
👉 Your rank, responsibilities, and salary potential remain the same regardless of the path chosen.
