A clear map of the nautical officer career pathway in the Indian Merchant Navy — from Deck Cadet to Master Mariner, every rank, every exam, every opportunity, based on official guidance from the Directorate General of Shipping.
Three approved routes lead to the bridge of a merchant vessel. Each requires sponsorship by a shipping company, clearance of IMUCET (where applicable), and medical fitness certified by a DGS-approved doctor.
The most popular route for aspiring deck officers — a year of intensive training at an IMU-affiliated institute, followed by structured shipboard training as a Deck Cadet, leading to a B.Sc. (Applied Nautical Science) and the Second Mate COC.
A three-year undergraduate programme at an IMU-affiliated institute, with deeper grounding in navigation, ship stability, meteorology, maritime law, and cargo operations before cadet sea time and the Second Mate COC exam.
An entry-level pathway after 10th or 12th. Ratings progressively upgrade through RFPNW and Able Seafarer certifications, eventually qualifying for the NCV deck officer certificate and, with more sea time, foreign-going COC exams.
Every nautical officer must complete these DGS-approved courses at recognised maritime training institutes. Certificates carry a five-year validity and must be refreshed periodically.
From your first day as a Deck Cadet to the day you take command as Master — rank progression, sea time required, examinations at each stage, and indicative salary range.
12–18 months of structured shipboard training under the Chief Officer and Master, completing a Training Record Book (TRB) and Structured Shipboard Training Programme (SSTP) — the foundation of your entire career.
After cadet sea time and clearing the Second Mate (Foreign Going) written and oral exams at MMD centres in Mumbai, Chennai, or Kolkata — responsibilities include navigation watch, GMDSS operations, and chart corrections.
Responsible for passage planning, navigational chart management, and medical duties on board — building the operational competence needed for the Chief Mate exam after a minimum 9 months of further sea service.
The Chief Mate COC exam runs in two phases. As Chief Officer — second-in-command — responsibilities span cargo operations, stability management, crew safety, and ISM implementation, after 18 months minimum sea service as watchkeeping officer.
After 36 months of approved sea service (including at least 12 as Chief Officer), the Master (FG) exam leads to command of any merchant vessel — ultimate responsibility for ship, cargo, crew, and legal compliance.
An optional, prestigious postgraduate-level exam demonstrating advanced mastery in maritime law, navigation, ship construction, and meteorology — valued for senior shore roles in administration, classification societies, and academia.
DG Shipping conducts COC examinations at MMD centres in Mumbai, Chennai, and Kolkata. Each level comprises written papers and oral assessment.
First officer-level certificate. Requires pre-sea training, 18 months structured cadet sea time, SSTP, TRB, and all mandatory STCW modular and simulator courses.
Two-phase exam. Phase I covers advanced navigation, cargo, and ship stability. Phase II covers advanced seamanship and ship management.
The command exam. Requires 36 months of approved sea service with at least 12 months as Chief Officer. Covers ship command, maritime law, and emergency management.
The highest professional certification in the deck department — an advanced postgraduate-level exam with a mandatory dissertation, recognised globally.

A nautical officer's competencies open doors far beyond the bridge. After sea experience, many officers transition to shore-based careers across the maritime ecosystem.
Vessel inspections for classification societies, P&I clubs, insurance underwriters, or as an independent surveyor.
Join DG Shipping as a Nautical Surveyor — statutory surveys, PSC inspections, flag state audits, IMO policy work.
Guide vessels through ports and channels. Major Indian ports recruit experienced Master Mariners as licensed pilots.
Fleet, Technical, or Marine Superintendent roles overseeing operations, maintenance, and compliance.
Teach at IMU-affiliated institutes and MTIs — Extra Master holders are especially sought after as faculty.
Maritime lawyer, P&I correspondent, cargo claims surveyor, or marine insurance underwriter.
Port operations, berth allocation, vessel traffic services, and terminal logistics.
Offshore platforms and FPSOs as Dynamic Positioning Officers, Marine Advisers, or OIMs.
IMO, IOPC Funds, IHO, or World Maritime University — policy roles for experienced Master Mariners.
