ADNS Course in Merchant Navy
The Advanced Diploma in Nautical Science (ADNS) is a maritime education pathway for students and cadets who want to build a career as a deck officer in the Merchant Navy. Unlike the one-year DNS route, ADNS is generally associated with the later stage of nautical training and, depending on the program, may also be offered as a structured India-and-UK pathway.
There is an important point to understand before choosing this course: ADNS is not the same as DNS. The two names are sometimes used together because they form part of the same broader deck-officer career pathway, but they represent different stages or program structures.
The Directorate General of Shipping (DGS) describes the nautical officer career as a progression from deck cadet towards second officer, chief officer, and eventually master mariner.
What Is ADNS in the Merchant Navy?
ADNS stands for Advanced Diploma in Nautical Science.
It is designed around the professional development of students preparing for a career on the deck side of merchant ships. Training focuses on nautical knowledge, navigation, seamanship, ship operations, safety, and the skills required to progress towards officer-level responsibilities.
The exact structure can differ between institutions. Some programmes use ADNS as a qualification associated with the post-DNS/sea-training stage, while newer programmes may offer ADNS as a complete international pathway involving study in India followed by study in the United Kingdom.
This distinction matters when comparing ADNS courses. A student should not assume that every course advertised as “ADNS” has the same duration, qualification, admission process, or certification pathway.
ADNS vs DNS: What Is the Difference?
DNS and ADNS are connected to the deck-officer career, but they are not interchangeable.
DNS | ADNS |
Diploma in Nautical Science | Advanced Diploma in Nautical Science |
Usually a 1-year pre-sea programme | Structure depends on the institution |
Designed as an entry route after Class 12 PCM | Generally represents an advanced stage or an alternative structured program. |
Followed by onboard training | May include advanced academic/nautical training and/or sea-training components |
Leads into the deck-cadet pathway | Builds towards higher-level nautical qualification |
Offered by DGS/IMU-approved institutions under the applicable framework | Recognition and structure must be checked for the specific program. |
The standard Indian DNS route is currently described by IMU as a one-year residential program, after which students proceed towards the required sea training and competency examinations.
Some established nautical training programs have historically used ADNS to describe the qualification obtained after the pre-sea and onboard stages. A published course structure from one maritime program, for example, places DNS in the first year and ADNS after the subsequent onboard semesters.
ADNS Course Duration
There is no single duration that applies to every ADNS program in India. This is because the name ADNS is used for different program structures.
For example, some international ADNS programs currently advertised in India follow a two-year study pathway, with the first year conducted in India and the second year at a UK maritime institution.
Other programs use ADNS as an advanced qualification after the candidate has completed DNS and the required onboard training. Therefore, before applying, students should check the following:
- Total course duration
- Where each year is conducted
- Qualification awarded
- DGS approval or recognition
- UK MCA recognition, if applicable
- Sea-time requirements
- Sponsorship arrangement
- Certification pathway after completion
This is particularly important because the title “ADNS” alone does not tell you the complete career pathway.
ADNS Eligibility Criteria
Eligibility depends on the particular ADNS program.
For students coming directly after Class 12, an ADNS program may specify requirements similar to other nautical science entry programs, such as the following:
- Class 12 with Physics, Chemistry and Mathematics
- Required minimum percentage in PCM
- Required English marks
- Prescribed age limit
- Medical fitness
- Eyesight and colour-vision standards
- Successful completion of the institute’s admission or selection process
However, programs where ADNS represents an advanced stage after DNS can have completely different entry requirements because the candidate is already expected to have completed earlier maritime training. For this reason, students should not use the eligibility criteria of one ADNS institute for another.
The standard DNS route, for comparison, requires 10+2 with PCM and at least 60% aggregate in PCM and 50% in English, according to IMU’s current program information.
ADNS Course After 12th
Students searching for ADNS after 12th grade need to be especially careful about the program structure.
A conventional Indian deck officer pathway generally starts with a recognized pre-sea program such as DNS. The student then completes the required onboard training and progresses through the competency-certification system. The current DGS nautical-officer career pathway identifies DNS as a fast-track entry route involving one year of pre-sea training followed by 18 months of sea time.
Some institutions, however, advertise ADNS as an integrated alternative program for students after Class 12. These programs need to be evaluated separately based on their approvals and the qualifications they actually lead to.

ADNS and Merchant Navy Career
The purpose of nautical training is to prepare candidates for the deck department.
A student entering this pathway can eventually progress through ranks such as the following:
- Deck Cadet
- Third Officer
- Second Officer
- Chief Officer
- Master Mariner/Captain
The journey is not completed simply by receiving a diploma. Candidates have to complete the required sea service, training, examinations, and competency certification. DGS currently describes the nautical officer pathway as progressing from deck cadet to master and outlines the examinations and certification requirements involved in reaching officer ranks.
ADNS Course and Sea Training
Practical shipboard experience is an essential part of becoming a deck officer. Students learn the theoretical side of navigation and ship operations during their academic training, but professional competence is developed further through actual sea service.
Depending on the program, students may undertake the following:
- Shipboard training
- Bridge watchkeeping
- Navigation-related duties
- Seamanship practice
- Safety procedures
- Cargo operations
- Ship maintenance activities
- Record keeping and training assessments
The actual sea-time requirement depends on the qualification and certification route being followed. For the standard Indian DNS route, DGS currently describes the pathway as one year of pre-sea training followed by 18 months of sea time.
ADNS Course and Certificate of Competency
A diploma by itself should not be confused with a Certificate of Competency (CoC).
The CoC is the professional certification that allows a seafarer to serve in a particular officer capacity.
For the Indian nautical-officer pathway, DGS conducts and regulates the competency-certification process. IMU also states that successful DNS candidates become eligible to take the examinations required for obtaining a CoC as a deck officer.
Students considering an ADNS program should, therefore, ask exactly the following:
- What qualification will I receive?
- Which authority recognizes it?
- What CoC can I progress towards?
- How much sea time is required?
- Where will the sea training take place?
- Which authority conducts the final competency examination?
These questions are much more useful than judging a course only by its name.
ADNS India-UK Maritime Programmes
One form of ADNS currently available in India is an India-UK study pathway.
For example, Training Ship Varren has advertised an ADNS program in which students spend the first year in India and the second year at City of Glasgow College in the UK. Its published program information describes the course as a UK MCA-approved pathway. This type of program can provide international academic exposure, but students should examine the complete qualification and certification pathway before taking admission.
A program being conducted partly in the UK does not automatically mean that every merchant navy certification requirement is satisfied. Students should check the relevant approval and certification details for the exact course.
Is ADNS Approved by DG Shipping?
This depends on the specific program and institute. DGS maintains approval requirements for maritime training in India and distinguishes between DGS-approved and non-DGS-approved courses. Its 2024 circular states that institutes conducting non-DGS-approved courses must not present them as DGS-approved and that DGS approval is required for relevant STCW modular training.
Therefore, students should never assume that an institute’s use of the term “ADNS” automatically means that the course itself is DGS-approved.
Before paying any admission fee, verify:
- Institute’s DGS approval
- Course approval/status
- Qualification awarded
- STCW compliance
- Applicable maritime authority
- Sea-training arrangement
- Sponsorship or placement terms
ADNS Course Fees in India
There is no single ADNS fee applicable throughout India.
The cost depends heavily on the type of program. An India-only advanced nautical program can have a very different fee structure from an India-UK program because an international program may include the following:
- Tuition fees in India
- UK tuition fees
- Hostel and accommodation
- Food
- Visa-related expenses
- Travel
- Insurance
- Examination charges
- Maritime training charges
- STCW courses
- Other administrative expenses
Students should therefore compare the total cost of the complete program, rather than looking only at the first-year tuition fee. It is also worth remembering that a course advertised as “sponsored” does not necessarily mean that every educational expense is paid by the company. Sponsorship terms differ between companies and programs.
ADNS Sponsorship
Sponsorship is particularly important in the Indian Merchant Navy admission system. For the standard DNS route, DGS currently describes sponsorship by a shipping company as part of the approved nautical-officer entry pathways. However, the sponsorship arrangement for an ADNS program depends on the specific institute and company involved.
Before accepting a sponsorship offer, students should understand:
- Which shipping company is providing the sponsorship
- Whether the sponsorship guarantees shipboard training
- Whether the company pays any course fees
- Which institute the candidate will attend
- What happens if the candidate fails an academic or medical requirement
- Whether placement is guaranteed or subject to conditions
- What documents are issued after selection
Never treat the word “sponsorship” as automatically meaning a completely free course.
ADNS Medical Requirements
Medical fitness is one of the most important requirements for a career at sea.
Candidates entering a maritime program have to satisfy the applicable medical standards, including requirements relating to
- Eyesight
- Colour vision
- Hearing
- Physical fitness
- General health
For the Indian nautical-officer route, medical fitness must be certified according to the standards prescribed by DGS and through an appropriately approved medical practitioner. DGS specifically advises aspiring seafarers to use DGS-approved maritime training and medical systems.
Students should complete the appropriate maritime medical examination before committing to a long and expensive course.
ADNS Eyesight Requirements
Deck officers rely heavily on visual information while navigating and operating a ship. The applicable eyesight requirements depend on the certification route and maritime authority.
For Indian DNS admissions, the prescribed eyesight and medical standards are part of the eligibility requirements. IMU also requires candidates entering marine programs to meet the physical fitness and eyesight standards prescribed by DGS. Candidates should not rely on an ordinary eye test from a local optical shop to determine their eligibility. A proper maritime medical examination is the appropriate assessment.
ADNS Course Subjects and Training Areas
The exact curriculum varies by program, but nautical training generally develops knowledge in areas such as
- Navigation
- Seamanship
- Ship operations
- Maritime safety
- Cargo operations
- Ship stability
- Maritime regulations
- Bridge procedures
- Communication
- Emergency response
The standard DNS curriculum itself combines classroom education with practical maritime training, including navigation, seamanship, and safety management. An advanced nautical program builds on these professional skills and prepares students for greater responsibility in the deck department.
Career After ADNS
The long-term objective is to progress towards an officer position onboard a merchant vessel.
A typical career can develop through the following ranks:
- Deck Cadet
- Third Officer
- Second Officer
- Chief Officer
- Master/Captain
The time required for progression is not fixed. It depends on sea service, examinations, competency certification, company requirements, and the individual’s performance. A student should therefore look at ADNS as part of a long-term professional qualification pathway, rather than as a course that immediately results in an officer’s rank.
Advantages of an ADNS Course
An appropriate ADNS program can offer several advantages:
- Professional training focused on the deck department
- Practical maritime exposure
- A structured pathway towards officer certification
- International exposure in programmes involving overseas study
- Development of navigation and ship-operation skills
- Opportunity to build a career in global shipping
The actual value depends on the institute, approval status, company connections, and certification pathway.
Things to Check Before Taking ADNS Admission
The name of a course is not enough to decide whether it is a good option.
Before paying any admission fee, check:
- Whether the institute is approved by the appropriate maritime authority
- Whether the specific ADNS programme is approved or recognised
- Exact qualification awarded
- Total duration
- Sea-training arrangement
- Sponsorship details
- Placement terms
- Total course fees
- Additional expenses
- Medical requirements
- CoC pathway after completion
- Recognition of overseas qualifications, where applicable
DGS itself advises prospective seafarers to use approved maritime training institutes and distinguish between pre-sea and post-sea training.
JMDI Academy for Merchant Navy Aspirants
Students planning a career in the Merchant Navy often have to prepare for entrance examinations, sponsorship tests, and interviews before they can enter their chosen training program.
JMDI Academy, Dehradun, provides preparation support for Merchant Navy aspirants, including PCM, English, aptitude, mock tests, communication, and interview preparation. For students comparing DNS and ADNS pathways, proper guidance is useful because the admission process and qualification structure can vary significantly between institutes.
Merchant Navy Decoded App for Aspirants
The Merchant Navy Decoded app is another useful resource for students exploring maritime careers.
It provides merchant navy-related information and preparation resources, including an IMU-CET test series for entrance-exam practice. Students can use the app while researching courses, colleges, and entrance examinations. For admission, approval, and certification details, the official information for the specific institute and program should always be used.

Final Thoughts
The ADNS course in the merchant navy can be an interesting option for students interested in a career on the deck side, but it needs to be understood properly before admission.
The biggest point is that ADNS does not have one identical structure across every institute. In some cases, it represents an advanced stage following DNS and onboard training. In others, it is offered as a separate integrated program, including international study.
That makes verification especially important. Students should look beyond the course name and check the institute’s approval, qualification awarded, sea-training arrangement, sponsorship, total fees, and route towards a certificate of competency.
For students entering the Indian Merchant Navy through the conventional deck-officer route, DGS currently identifies DNS as a one-year pre-sea pathway followed by the required sea service and competency certification.
A well-chosen ADNS program can form part of a strong maritime career, but the right choice depends on the recognition and career pathway attached to the particular program, not simply the title printed on the brochure.
FAQ’s (Frequently asked Questions)
No. DNS means Diploma in Nautical Science, while ADNS means Advanced Diploma in Nautical Science. They can appear at different stages of the deck-officer training pathway, depending on the program.
Some institutions offer ADNS programs to students after Class 12, while other ADNS qualifications are associated with the later stage of nautical training. The eligibility, therefore, depends on the specific program.
Not necessarily. ADNS stands for Advanced Diploma in Nautical Science. Some programs may have additional degrees or overseas academic qualifications attached to them, so students should check exactly what qualification they receive.
No. Completing an ADNS program does not immediately make someone a captain. A deck officer has to complete the required sea service, examinations, and competency certifications and then progress through the officer ranks.
There is no universal answer. DNS is a well-established entry route into the Indian deck-officer pathway, while ADNS programs can have different structures. The better choice depends on the program’s approval, cost, sea training, and certification pathway.
Not necessarily. Sponsorship requirements depend on the particular program and company. Students should check the exact admission and placement arrangement before enrolling.
A recognized nautical qualification can support an international maritime career, but the candidate must meet the certification, medical, STCW, and other requirements of the relevant flag state and employer.
No course title by itself guarantees employment. Placement depends on the program’s contractual terms, sponsorship arrangement, eligibility, successful completion of training, and the applicable company and regulatory requirements.
