Over 2.4 lakh Indian seafarers are working on ships across the world right now. But every year, thousands of them face delays, missed job opportunities, and even rejected applications — all because of one document: the CDC.

If you're planning to join the merchant navy, or you're already a seafarer looking to renew your papers, you already know how important the Continuous Discharge Certificate is. Without it, you simply cannot sail on any commercial vessel. No CDC means no job, no sea time, and no career progress.

This guide breaks down the entire CDC application process in India for 2026 — from eligibility to the final step of collecting your booklet. Whether you're a fresh cadet applying for the first time or an experienced officer going through renewal, this is the only guide you'll need. We've covered documents, fees, MMD office details, common mistakes, and answers to the most-asked questions.

Let's get into it.

What Is a CDC (Continuous Discharge Certificate) and Why Do Indian Seafarers Need It?

The Continuous Discharge Certificate, commonly called CDC, is the official identity document of an Indian seafarer. Think of it as your professional passport for the sea.

Under the Merchant Shipping Act, 1958, every Indian national working on a merchant vessel — whether as a deck officer, engine officer, rating, or cadet — must hold a valid CDC. It is a legal requirement, not just a formality.

The CDC serves two main purposes. First, it proves your identity as a certified seafarer. Second, it acts as a record of your sea service. Every ship you sail on gets an entry in your CDC booklet, which is how your total sea time is tracked over your career. This sea time is what you need to sit for promotions, apply for higher certificates, and qualify for better jobs.

How is CDC different from other seafarer documents?

Many first-timers get confused between CDC, CoC, and STCW certificates. Here's a simple breakdown:

• CDC (Continuous Discharge Certificate): Your seafarer identity document and sea service record. Mandatory for all seafarers.
• CoC (Certificate of Competency): A qualification certificate for officers. It proves you've passed the required exams to work at a specific rank. Not required for ratings.
• STCW Certificates: Safety training certificates (Basic Training, PSSR, EFA, etc.) that prove you've completed specific courses required by international maritime law.

You need all three types over the course of your career, but CDC comes first.

The CDC is issued by the Directorate General of Shipping (DGS), which operates under India's Ministry of Ports, Shipping and Waterways. All CDC applications go through the DGS Seafarers Portal.

Who Is Eligible to Apply for a CDC in India?

Not everyone can walk in and apply for a CDC. There are specific eligibility requirements that you need to meet before you start your application.

Basic Eligibility Criteria:

• You must be an Indian citizen holding a valid Indian passport
• You must be at least 17 years of age
• You must hold a valid Medical Fitness Certificate (Form ENG 1) from a DGS-approved doctor
• You must have completed the required pre-sea training from an IMO-approved institute

STCW Basic Training Requirement:

Before applying for a CDC, you need to complete the four STCW Basic Safety Training (BST) modules:

1. Personal Survival Techniques (PST)
2. Fire Prevention and Fire Fighting (FPFF)
3. Elementary First Aid (EFA)
4. Personal Safety and Social Responsibilities (PSSR)

These are done at an approved maritime training institute in India. Without these, your CDC application will be rejected.

Fresh Seafarers vs. Experienced Mariners:

• Fresh seafarers (first-time applicants): Need to complete a pre-sea training course (like GP Rating, Nautical Science, or Marine Engineering) from a DGS-approved institute, along with STCW Basic Training.
• Experienced seafarers: If you already sailed on foreign flag vessels or previously held a CDC that has since expired, you'll follow a slightly different documentation path and may need to produce previous CDC copies or discharge records.

For Cadets:

Deck and engine cadets can apply for a CDC after completing their first year of training or upon joining a vessel for their sea phase. Some training institutes assist with CDC applications as part of their placement process.

For Ratings:

GP Ratings, Electro-Technical Ratings, and other ratings need their pre-sea course certificate along with the standard documents. The process is the same, but the pre-qualification documents differ based on your category.

Documents Required for CDC Application in India — Complete Checklist

Getting your documents right is the most important part. A single mismatch or missing paper can delay your application by weeks. Here's the complete list:

A few things to double-check before uploading:

• Your name on the passport and training certificates must match exactly — even a small spelling difference causes problems
• Your medical certificate should not be more than 2 years old (check the validity at the time of appointment)
• Passport should be valid for at least 6 months from the date of application, not just the appointment date
• Photographs must be recent — old photos are a common reason for rejection at the MMD counter

Step-by-Step CDC Application Process in India (Online via Seafarers Portal)

The entire process is done online through the official DGS Seafarers Portal: seafarers.dgshipping.gov.in

Here's how to go through it, step by step.

Step 1: Register on the DGS Seafarers Portal

Go to seafarers.dgshipping.gov.in and create a new account if you don't already have one. You'll need your passport number, date of birth, and mobile number to register. Make sure you use an active mobile number because all OTPs and notifications come to it.

Once registered, log in to your account.

Step 2: Generate and Verify Your INDOS Number

INDOS stands for Indian National Database of Seafarers. It's your unique identification number in the DGS system.

If you don't have an INDOS number yet, apply for one on the portal. This usually gets processed within 24–48 hours. If you already have one from a previous application or training institute registration, verify it's correctly linked to your profile.

Important: Your INDOS number is linked to your passport. If you get a new passport, you'll need to update this in the system before proceeding.

Step 3: Complete the Online CDC Application Form

Navigate to the CDC application section in your dashboard. Fill in all required fields carefully:

• Personal details (name, date of birth, address)
• Passport details
• Training institute details
• Sea service history (if applicable)

Take your time with this form. Errors here create problems at the verification stage.

Step 4: Upload All Required Documents

Scan all your documents clearly. The portal accepts PDF and JPEG formats. Make sure:

• File sizes are within the portal's limits (usually 500KB to 1MB per file)
• Scans are clear and fully readable — blurry or cropped scans get rejected
• Documents are uploaded in the correct fields

Step 5: Pay the CDC Application Fee Online

Once the form is filled and documents are uploaded, proceed to payment. The fee can be paid via:

• Net banking
• Debit/Credit card
• UPI

After payment, save and download your payment receipt. You'll need to carry this to your MMD appointment.

Step 6: Book Your Appointment at the Nearest MMD Office

After payment, the portal will let you book an appointment at your preferred Mercantile Marine Department (MMD) office. Available slots depend on your location and the MMD's schedule.

Choose a date that gives you enough time to gather physical copies of all your documents. Don't book the earliest slot if you're still waiting on a document.

Step 7: Attend In-Person Verification

On your appointment day, visit the MMD office with:

• All original documents
• Self-attested photocopies of each document
• Your appointment confirmation (printout or on phone)
• Payment receipt

An officer will verify your documents against what was uploaded online. If everything matches, your application gets approved at this stage. If there's an issue, they'll inform you what needs correction.

Step 8: Track Your Application Status Online

After your in-person verification, log back into the portal to track your application status. The status usually moves through stages like: Submitted → Under Review → Approved → Dispatched.

Processing time after successful verification is typically 15–30 working days, though this can vary based on the volume of applications at your MMD.

Step 9: Receive and Collect Your CDC Booklet

Once approved, your CDC booklet is either dispatched by post to your registered address or made available for collection at the MMD office - depending on the option you selected during application.

Keep your CDC booklet safe. It's extremely difficult to replace if lost, and the process for a duplicate CDC involves additional steps and documentation.

CDC Application Fees in India (2026 Updated)

Here's the current fee structure as per DGS guidelines for 2026:

Note: Fees are subject to change. Always confirm the current amount on the official DGS portal before making payment.

Mode of Payment:

All payments are done online through the DGS Seafarers Portal using net banking, UPI, or debit/credit cards. Cash payments are not accepted at MMD offices.

Penalty for Expired CDC:

Sailing on an expired CDC is a serious violation. Apart from being illegal, it can result in your CDC being suspended or cancelled by DGS. There's no standard "penalty fee" for expired CDC - instead, you simply need to apply for renewal. But the consequences of sailing with an expired document are severe (covered in the renewal section below).

Refund Policy:

Fees paid on the portal are generally non-refundable. If your application is rejected due to document issues, you'll need to reapply and pay the fee again. This is why it's critical to get your documents right the first time.

CDC Renewal Process in India — What You Need to Know

When Does Your CDC Expire?

A CDC issued to Indian seafarers is valid for 10 years from the date of issue. After that, you need to apply for renewal. Some seafarers also have CDCs issued before the 10-year norm that may have different validity periods — check the issue date and expiry on your booklet.

DGS recommends starting the renewal process at least 6 months before your CDC expires, especially if you have upcoming contracts. Processing delays during peak periods can stretch timelines.

Documents for CDC Renewal:

The renewal process requires most of the same documents as a fresh application, plus:

• Your current (expiring) CDC booklet
• Updated Medical Fitness Certificate (Form ENG 1)
• Proof of continued sea service or training (if applicable)
• Updated STCW certificates (if any have expired)

Consequences of Sailing with an Expired CDC:

This is not something to take lightly. If you sail on a vessel with an expired CDC:

• You're in violation of the Merchant Shipping Act, 1958
• The ship can be detained by Port State Control during inspections
• Your CDC can be cancelled or suspended by DGS
• Your employer (shipping company) can face penalties
• Future job applications will be affected when companies see the violation on your record

Don't let it come to this. Set a calendar reminder 6 months before your expiry date.

CDC Application at Major MMD Offices — Mumbai, Chennai, Kolkata & Kochi

India has MMD offices in several maritime cities. Here are the four major ones where most seafarers process their CDC:

Mumbai MMD

Address: Mercantile Marine Department, Shram Shakti Bhavan, 2nd Floor, P D'Mello Road, Masjid Bunder, Mumbai – 400009

Working Hours: Monday to Friday, 10:00 AM – 5:00 PM (closed on public holidays)

Appointment Process: Through DGS Seafarers Portal only. Walk-ins are generally not entertained.

Mumbai MMD handles the highest volume of applications in India. Appointment slots here fill up quickly, especially between November and March when many seafarers are between contracts. Book your slot early.

Chennai MMD

Address: Mercantile Marine Department, Rajaji Bhavan, Besant Nagar, Chennai – 600090

Working Hours: Monday to Friday, 9:30 AM – 5:00 PM

Appointment Process: DGS Seafarers Portal. The Chennai office is generally less congested than Mumbai, and slots are usually more readily available.

Chennai MMD serves seafarers from Tamil Nadu, Andhra Pradesh, and Telangana primarily.

Kolkata MMD

Address: Mercantile Marine Department, 304, Strand Road, Kolkata – 700001

Working Hours: Monday to Friday, 10:00 AM – 4:30 PM

Appointment Process: DGS Seafarers Portal. Kolkata MMD serves seafarers from West Bengal, Odisha, and northeast India.

Kochi MMD

Address: Mercantile Marine Department, Willingdon Island, Kochi – 682003

Working Hours: Monday to Friday, 9:30 AM – 5:00 PM

Appointment Process: DGS Seafarers Portal. Kochi serves seafarers from Kerala and parts of Karnataka.

Tips on Choosing the Right MMD:

• You can apply at any MMD in India, not necessarily the one closest to your home address
• Choose an MMD based on availability of appointment slots, not just location
• If you're in a time crunch, check all four portals before booking — sometimes an MMD further from you has earlier availability
• Carry both originals and self-attested photocopies to every MMD visit, regardless of which office you go to

Common Reasons for CDC Application Rejection or Delay in India

Knowing what typically goes wrong will save you a lot of time and frustration.

1. Name Mismatch Across Documents

This is the most common reason for rejection. If your passport says "Rajan Kumar" but your training certificate says "R. Kumar," the system flags it. Make sure all documents have your full name spelled exactly as it appears on your passport.

2. Expired Medical Fitness Certificate

Form ENG 1 has a validity period. If it expired before your appointment date, your application stalls right there. Get a fresh medical done if there's any doubt.

3. INDOS Number Issues

Wrong INDOS number, or a number not properly verified in the system, causes delays. Always confirm your INDOS number is active and linked to your current passport before applying.

4. Incorrect Passport Details

Even a one-digit error in your passport number in the application form can cause rejection. Triple-check this.

5. Blurry or Incomplete Document Uploads

The portal flags documents that are unreadable. Use a proper scanner if possible. Avoid clicking photos of documents with a phone in poor lighting.

6. Training Certificate from a Non-Approved Institute

Your pre-sea training and STCW courses must be from institutes approved by DGS and recognized by IMO. Certificates from non-approved institutes will not be accepted. Check DGS's approved institute list before enrolling in any course.

How to Rectify and Reapply After Rejection:

If your application is rejected:

• Log in to the portal and check the rejection reason (it's usually specified)
• Correct the issue — get the right document, fix the mismatch, or update your details
• Submit a fresh application (you'll need to pay the fee again)
• If rejected at the MMD counter during in-person verification, ask the officer for a written note of the reason. This helps you prepare better for your next visit.

CDC for Fresh Seafarers vs. Experienced Seafarers — Key Differences

The CDC application process is broadly the same for everyone, but the supporting documents and pathways differ based on your experience level.

Fresh Seafarers (First-Time Applicants):

If you've never sailed before and are applying for a CDC for the first time, you need:

• Completion of a recognised pre-sea course (GP Rating, Nautical Science B.Sc., Marine Engineering Diploma, etc.)
• STCW Basic Safety Training (all four modules)
• Proof of admission or graduation from an approved institute
• Medical Fitness Certificate

You do not need a job offer letter to apply for a CDC. Your application is based on your training qualifications.

Experienced Seafarers:

If you've sailed before — whether on Indian or foreign flag vessels — you'll need to produce:

• Copies of previous CDC (if you had one)
• Discharge book or sea service certificates
• Updated medical and STCW certificates
• CoC (if you're an officer) — relevant for the application record but not mandatory for CDC itself

For Cadets:

Deck and engine cadets in their sea phase can apply for CDC through their training institute, which often handles the process as part of placement. Some institutes have dedicated help desks for CDC applications.

Role of Manning Agents:

Many seafarers, especially first-timers, approach manning agents (crewing agencies) for help with the CDC process. Manning agents are well-versed in the documentation requirements and can guide you through each step. Some also assist with appointment booking and follow-up. If you're confused about any part of the process, a reputable manning agent is a good resource - just make sure they're registered and legitimate.

Frequently Asked Questions About CDC Application in India

1. What is the full form of CDC in the merchant navy?

CDC stands for Continuous Discharge Certificate. It's the identity and service record document issued to Indian seafarers by the Directorate General of Shipping.

2. How long does it take to get a CDC in India?

After a successful in-person verification at the MMD, it typically takes 15 to 30 working days to receive your CDC. Some applicants report receiving it faster; others face longer waits during peak periods. You can track the status on the DGS portal.

3. Can I apply for CDC without a job offer?

Yes. You don't need an employment offer to apply for a CDC. As long as you meet the eligibility requirements (training, medical, INDOS), you can apply.

4. What happens if my CDC is lost or damaged?

You need to apply for a duplicate CDC. This involves filing a First Information Report (FIR) at your local police station for a lost CDC, submitting an affidavit, and applying through the DGS portal with the required documents. There is an additional fee for duplicate CDC issuance.

5. Is CDC required for inland vessel seafarers?

Seafarers working exclusively on inland waterways (rivers, lakes) typically fall under different regulations and may not require a CDC. However, those working on coastal or international vessels must have one. Check with DGS or a maritime legal advisor if you're unsure of your vessel category.

6. Can I apply for CDC offline?

No. Since DGS digitised the process, all CDC applications must be submitted online through the Seafarers Portal. There is no offline application option currently available.

7. What is the validity period of a CDC in India?

A CDC issued in India is valid for 10 years from the date of issue.

8. Can a CDC be cancelled or suspended?

Yes. DGS has the authority to cancel or suspend a CDC in cases of serious misconduct, violation of maritime laws, sailing on an expired CDC, or fraudulent documentation. A suspended CDC cannot be used until the matter is resolved and the suspension is lifted.

9. Is INDOS number mandatory before CDC application?

Yes. You must have a valid, verified INDOS number before you can complete the CDC application form on the portal.

10. What is the difference between CDC and CoC?

CDC is your seafarer identity and service record — required for everyone. CoC (Certificate of Competency) is a rank qualification certificate required only for officers. You get a CoC by clearing DGS exams. Both are different documents and serve different purposes.

11. Can NRI seafarers apply for an Indian CDC?

If an NRI holds a valid Indian passport and meets the eligibility criteria (training, medical fitness), they can apply for an Indian CDC. The process is the same.

12. How do I check my CDC application status online?

Log in to the DGS Seafarers Portal at seafarers.dgshipping.gov.in, go to your dashboard, and look for the application tracking section. Your application's current stage will be listed there.

Conclusion

The CDC application process in India is more straightforward than it seems — as long as you prepare your documents carefully and follow each step in order. Register on the portal, get your INDOS number sorted, fill in the form correctly, upload clear documents, pay the fee, book your appointment, attend verification, and then wait for your booklet.

The biggest mistakes people make are rushing the document preparation stage or ignoring expiry dates on medical certificates and STCW cards. Take your time, double-check everything, and the process will go smoothly.

If you're a fresh seafarer just starting your career or an experienced mariner planning your next contract, getting your CDC right is the first step to everything that comes after.
