DG Shipping and MEO examinations

In short

The Directorate General of Shipping (DG Shipping, DGS) — renamed the Directorate General of Maritime Administration (DGMA) in 2026 under section 7 of the Merchant Shipping Act, 2025, and still widely called DG Shipping — is the maritime regulator under the Ministry of Ports, Shipping and Waterways, headquartered in Mumbai, and it alone issues Indian Certificates of Competency (COC) to marine engineers. The Marine Engineer Officer (MEO) examinations — Class IV, Class II and Class I, with their near-coastal and electro-technical variants — are the statutory licence ladder a Marine Engineering graduate climbs from Junior/Fourth Engineer to Chief Engineer. They exist because India is a party to the IMO's STCW Convention, 1978 as amended (Manila 2010), so an Indian COC must be recognised worldwide. The examinations are the single most important "exam" in a marine engineer's working life: written papers plus function-based orals conducted by DGS surveyors/examiners, with mandatory sea service and approved courses as eligibility. University vivas, campus interviews at Indian shipping companies and ship-management offices (SCI, Great Eastern, Essar/Seven Islands, Anglo-Eastern, Fleet, Synergy, MSC, Maersk, Executive Ship Management) routinely test whether a student understands this regulatory ladder.

Explained

DG Shipping: mandate and legal framework

• DG Shipping administers merchant shipping law in India: ship registration and survey, seafarer training, examination and certification, safety and pollution-prevention enforcement, flag-State and port-State control, and casualty investigation.
• Statute: the Merchant Shipping Act, 2025 (Act 24 of 2025), in force from 15 March 2026, which repealed the Merchant Shipping Act, 1958. Certification of seafarers sits in sections 45-53 (certificates to be held by seafarers, s.45; certificates of competency and proficiency, s.46; training, s.47; examinations, s.48; recognition of foreign certificates, s.50); the Director-General's office is created by section 7, and certificates can be cancelled or suspended under section 312. A large set of new Merchant Shipping Rules, 2026 has been notified under the 2025 Act; rules made under the 1958 Act that have not yet been replaced continue under its savings clause (section 324), so confirm which rule is in force for the provision you are quoting.
• Certification rules: the M.S. (STCW for Seafarers) Rules, 2014 (as amended, made under the 1958 Act and continued under the 2025 Act) and the engineer-officer and electro-technical-officer training and certification provisions, read with DGS Merchant Shipping Notices (M.S. Notices), Engineering Circulars and Training Circulars, fix syllabi, sea service, exemptions and fees. These circulars change often — always check the latest on the DGS site rather than an older guide.
• Field offices: Mercantile Marine Departments (MMD) at Mumbai, Chennai, Kolkata and Kochi (with sub-offices) conduct surveys, oral examinations and certificate issue. Written papers are conducted under the DGS Examination of Engineers scheme; DGS has progressively moved written assessment to computer-based/online centres with a seafarer e-governance portal for applications, fees and results.
• Allied bodies: Indian Maritime University (IMU), Chennai (degree-awarding, IMU CET entrance), Indian Register of Shipping (IRS) and other IACS class societies, Seamen's Provident Fund / Shipping Master offices, and the Indian National Database of Seafarers (INDoS).

The COC ladder — what each certificate permits

• COCs are endorsed with limitations — propulsion power, voyage area (unlimited/NCV), and ship type. Additional tanker endorsements (oil, chemical, gas — basic and advanced) are required to serve on those ships.
• Older/intermediate Indian grades (and Part A / Part B splits of a written examination) exist for particular routes; the exact grade structure applicable to a candidate is set by the current certification rules.
• A COC is the legal authority to hold the rank; a Continuous Discharge Certificate (CDC) is the service record/identity document, and the watchkeeping certificate records approved watchkeeping service.

Entry routes to the first COC (Class IV)

• 4-year B.E./B.Tech Marine Engineering at a DGS-approved institute (IMU campuses, MERI Kolkata/Mumbai, MANET Pune, TMI, Samundra, AMET and others) — the mainstream route; admission largely through IMU CET or institute-level/JEE-linked channels.
• GME (Graduate Marine Engineer) — a one-year DGS-approved pre-sea course for mechanical (and allied) engineering graduates; converges onto the same Class IV examination.
• Alternate/Diploma routes and the ETO route (III/6) for electrical/electronics graduates.
• All routes then require approved seagoing service as a Trainee Marine Engineer (TME)/Junior Engineer, with a Training Record Book (TRB/TAR) signed on board, before the Class IV examination. The sea-service figure for degree/GME holders is commonly 6 months, and longer for alternate-route candidates — the exact period and any workshop-skills credit are fixed by the current DGS circular, so verify before planning.
• Other eligibility: medical fitness from a DGS-approved doctor (including eyesight and colour-vision standards), INDoS number, CDC, passport, completed STCW modular courses, and an approved pre-examination/preparatory course where prescribed.

How the examinations are structured

• Two stages for every grade: written papers, then function-based orals. Both must be cleared; the oral is conducted by DGS surveyors/examiners at an MMD and is where most candidates fail.
• STCW functions that the syllabus and orals are built around, at operational level (Class IV) and management level (Class II/I):
  1. Marine engineering — main engine, boilers, auxiliaries, operation and watchkeeping.
  2. Electrical, electronic and control engineering — generation, switchboards, automation, HV safety.
  3. Maintenance and repair — overhauls, clearances, workshop practice, surveys.
  4. Controlling the operation of the ship and care for persons on board — stability, statutory certificates, safety, pollution prevention.
• Typical written subject groups across Class IV/II/I: Engineering Knowledge (General) — boilers, auxiliaries, pumps, refrigeration, steering gear, survey and maintenance; Engineering Knowledge (Motor) — slow/medium-speed diesel engines, fuel injection, scavenging, turbocharging, running troubles, UMS operation; Electrotechnology — generators, motors, switchboards, protection, HV; Applied Mechanics / Naval Architecture and Ship Construction — strength, stability, trim, drydocking; and Safety, Management and Environment Protection (ISM, ISPS, MARPOL, SOLAS) which weighs heavily at management level. The exact paper list, marks and duration per grade are notified by DGS and have been revised over time.
• Pass standard is commonly 50% in each paper, with written passes valid for a limited period (frequently stated as 3 years) within which the orals must be cleared; failed papers can be re-sat individually. Attempt rules impose a waiting gap between oral attempts, increasing with repeated failures. Treat these numbers as "check the current notification" items.
• Orals cover function-wise questioning on your own ship's machinery, drawings and sketches, statutory certificates, emergency and troubleshooting scenarios, and "what will you do if…" judgement questions.

Mandatory STCW courses and documents

• Basic (all seafarers): Personal Survival Techniques (PST), Fire Prevention and Fire Fighting (FPFF), Elementary First Aid (EFA), Personal Safety and Social Responsibility (PSSR) — the STCW "Basic Safety Training" set; plus Security Training for Seafarers with Designated Security Duties (STSDSD).
• Operational/advanced: Advanced Fire Fighting (AFF), Medical First Aid (MFA), Proficiency in Survival Craft and Rescue Boats (PSCRB), Engine Room Simulator (ERS) operational, Refrigeration and Air-Conditioning, Welding, Machinery/Workshop skills as applicable.
• Management level (Class II/I): approved pre-sea-exam preparatory course, ERS management level, High Voltage Safety (management), Medical Care, Ship Security Officer (SSO) where required, plus MARPOL/environmental and leadership and managerial skills modules (STCW A-III/2 competences).
• Documents at every stage: COC, CDC, INDoS, medical certificate, passport and visas, STCW course certificates, TRB, and sea-service testimonials signed by the Chief Engineer/Master with ship particulars and propulsion power — because the kW figure on the testimonial decides which service counts.

Progression, validity and revalidation

• Class IV → Class II: approved seagoing service as a certificated engineer officer (commonly cited as 18 months as watchkeeping engineer, part of it on ships above the prescribed power) plus prescribed courses, then written + oral.
• Class II → Class I: STCW III/2 baseline for Chief Engineer is 36 months approved service as an engineer officer, of which not less than 12 months as Second Engineer while holding a Class II COC; Indian rules set the operative figures and may allow reduced periods — confirm from the current rules.
• Validity: a COC is valid 5 years and is revalidated on proof of continued competency — typically 12 months approved seagoing service in the preceding 5 years (or 3 months in the preceding 6 months immediately before revalidation), failing which refresher/updating courses and/or simulator assessment or supernumerary sea service are required.
• Discipline: DGS can suspend or cancel a COC after inquiry for incompetence, misconduct, drug/alcohol violation or fraudulent documents; casualty investigations under merchant shipping law can end a career.
• GATE link: GATE's Naval Architecture and Marine Engineering (NM) paper is the academic route to M.Tech/PSU jobs (Cochin Shipyard, GRSE, Mazagon Dock, Shipping Corporation of India shore cadre); it is not a substitute for a COC, and a COC is not a substitute for GATE.

Key points

• DG Shipping - maritime regulator under the Ministry of Ports, Shipping and Waterways; sole issuer of Indian COCs.
• MMD - Mercantile Marine Department offices (Mumbai, Chennai, Kolkata, Kochi) where orals and certificate issue happen.
• STCW - IMO convention (1978, as amended in Manila 2010) that makes Indian COCs internationally recognised.
• COC - Certificate of Competency: the legal licence for a rank; CDC is the service/identity record, not a licence.
• MEO Class IV - STCW III/1, engineering watchkeeping officer, ships of 750 kW and above.
• MEO Class II - Second Engineer on ships 3,000 kW and above; Chief Engineer below 3,000 kW.
• MEO Class I - Chief Engineer, unlimited propulsion power.
• ETO - STCW III/6 Electro-Technical Officer, a parallel certificate for electrical/electronics graduates.
• Entry routes - 4-year B.E. Marine Engineering, 1-year GME for mechanical graduates, or alternate/diploma routes.
• INDoS number - unique Indian seafarer identity number required for every application.
• Exam structure - written papers (commonly 50% pass each) followed by function-based orals; orals are the main failure point.
• Four STCW functions - marine engineering; electrical/electronic/control; maintenance and repair; controlling ship operation and care for persons.
• Sea service - must be approved, on ships of the required propulsion power, evidenced by signed testimonials and the Training Record Book.
• Validity - COC valid 5 years; revalidation needs recent sea service or refresher courses plus a valid medical.
• Written-pass validity - limited (commonly 3 years) to complete the orals; failed papers can be re-sat individually.
• Tanker and other endorsements - separate basic/advanced training required for oil, chemical and gas carriers.
• Mandatory courses - BST (PST, FPFF, EFA, PSSR), STSDSD, AFF, MFA, PSCRB, ERS, HV safety at management level.
• Rule currency - syllabi, sea-service periods, fees and attempt gaps are set by DGS circulars and change; always verify the latest.

Formulas and examples

Example 1 — Is the candidate eligible for MEO Class II (18 months required)?

• Contract 1: signed on 12 Jan 2024, signed off 20 Aug 2024 → 7 months 8 days.
• Contract 2: signed on 1 Feb 2025, signed off 15 Nov 2025 → 9 months 14 days.
• Total = 16 months 22 days. Requirement 18 months → short by 1 month 8 days; the candidate must sail again (or apply once the shortfall is made good). Service on a 600 kW harbour craft in between would not count towards an unlimited-power COC.

Example 2 — Rest-hours compliance for a watchkeeping engineer.

• Duties in 24 h: watch 0400–0800 (4 h), watch 1600–2000 (4 h), fire drill 1000–1100 (1 h), planned maintenance 1300–1430 (1.5 h) → work = 10.5 h.
• Rest = 24 − 10.5 = 13.5 h, which satisfies the 10-hour minimum.
• But the rest falls in five blocks: 0000–0400 (4 h), 0800–1000 (2 h), 1100–1300 (2 h), 1430–1600 (1.5 h), 2000–2400 (4 h) = 13.5 h. No single block is ≥ 6 h and there are more than two blocks → non-compliant, a classic port-State control and oral-exam catch. Fix: shift maintenance so one unbroken rest period of at least 6 hours exists.

Example 3 — Written examination result handling.

• Papers (each out of 100, pass 50): EK General 52, EK Motor 48, Electrotechnology 61, Applied Mechanics & Naval Architecture 55. Average = (52+48+61+55)/4 = 216/4 = 54.
• Average above 50 does not help: each paper must be passed, so EK Motor (48) is re-sat; the other three passes are carried forward within their validity period (commonly 3 years) to complete the orals.

Example 4 — Which COC does the Chief Engineer need?

• Ship has two main propulsion engines rated 1,800 kW each → total = 3,600 kW ≥ 3,000 kW → Chief Engineer must hold MEO Class I, and the Second Engineer MEO Class II.
• Same vessel re-engined to a single 2,400 kW engine → total 2,400 kW < 3,000 kW → a Class II holder may serve as Chief Engineer (subject to the endorsement on the certificate).

Example 5 — Revalidation check.

• COC issued 10 Mar 2022 → valid to about 9 Mar 2027.
• Sea service in the 5 years to date: 6 months in 2022 and 4 months in 2024 = 10 months < 12 months, and no service in the last 6 months.
• Therefore revalidation on sea service alone fails; the officer must complete the approved refresher/updating courses (and simulator assessment where required), hold valid BST/AFF/MFA/PSCRB certificates and a current medical, or sail the prescribed supernumerary period.

Where it is used

• Shipping companies and ship managers: SCI, Great Eastern Shipping, Seven Islands, Essar, Anglo-Eastern, Fleet Management, Synergy Marine, Executive Ship Management, MSC and Maersk crewing — all recruit and promote strictly against COC grade and endorsements.
• Offshore and dredging: ONGC-chartered OSVs, Dredging Corporation of India, SEACOR/Shipping offshore units — COC with the right power limitation and tanker/offshore endorsements is mandatory.
• DGS and MMD shore jobs: Surveyor-in-charge and Ship Surveyor posts, port-State control inspectors, flag-State auditors — a Class I COC with sea command is the usual entry qualification.
• Classification societies and P&I/marine insurance: Indian Register of Shipping, ABS, DNV, LR surveyors; marine warranty and claims surveyors in Mumbai, Chennai, Kandla and Kochi.
• Maritime education and simulators: IMU, MERI, MANET, Samundra, TMI faculty and ERS instructors — DGS requires approved instructors with management-level COCs.
• Shipyards, ports and PSUs: Cochin Shipyard, GRSE, Mazagon Dock, Hindustan Shipyard, major port trusts and LNG terminals use ex-sailing engineers for commissioning, trials and technical superintendence.

Interview questions

• Q: What is the difference between a COC and a CDC? A: The COC is the Certificate of Competency issued by DG Shipping that legally entitles you to serve in a rank; the CDC is the continuous discharge/service record and identity document showing the ships and periods you have served.
• Q: Which STCW regulation governs MEO Class IV and what does it permit? A: STCW Regulation III/1 — officer in charge of an engineering watch on ships powered by main propulsion machinery of 750 kW or more.
• Q: At what propulsion power must the Chief Engineer hold a Class I COC? A: 3,000 kW and above; below 3,000 kW a Class II holder may serve as Chief Engineer, subject to the endorsement on the certificate.
• Q: Why must India follow STCW at all? A: India is a party to the IMO STCW Convention; compliance keeps India on the IMO "white list" so Indian COCs are recognised by foreign flag States and port-State control.
• Q: What documents would you carry to an MMD oral examination? A: Application and fee receipt, written-pass results, COC/CDC, INDoS, passport, sea-service testimonials with ship particulars and kW, STCW and preparatory course certificates, Training Record Book and a valid medical.
• Q: How long is a COC valid and how is it revalidated? A: Five years; revalidation needs proof of recent approved sea service — commonly 12 months in the last 5 years or 3 months in the last 6 — plus valid safety courses and medical, otherwise approved refresher/updating training.
• Q: Which sea service counts towards the next COC? A: Only approved seagoing service, in the required capacity, on ships meeting the prescribed propulsion power and voyage area, properly recorded in the discharge book and testimonials.
• Q: What are the four STCW functions your orals are built on? A: Marine engineering; electrical, electronic and control engineering; maintenance and repair; and controlling the operation of the ship and care for persons on board.
• Q: A seafarer gets 13 hours rest in a day but in five separate blocks — is that compliant? A: No. Rest must be in not more than two periods, one of them at least 6 hours, with no more than 14 hours between consecutive rest periods.
• Q: Can a mechanical engineering graduate become a marine engineer officer? A: Yes — through the DGS-approved one-year GME pre-sea course, followed by approved sea service as a trainee engineer and then the MEO Class IV examination.
• Q: What is an ETO certificate and who takes it? A: The Electro-Technical Officer COC under STCW III/6, typically taken by electrical/electronics graduates after an approved course and sea service; it is a separate certificate from the MEO line.
• Q: Which Act governs merchant shipping in India today? A: The Merchant Shipping Act, 2025, in force from 15 March 2026, which repealed the Merchant Shipping Act, 1958; seafarer certification is in sections 45-53, new Merchant Shipping Rules, 2026 are being notified under it, and older rules such as the M.S. (STCW for Seafarers) Rules, 2014 continue under the savings clause until replaced.
• Q: Does clearing GATE help you get a COC? A: No. GATE (Naval Architecture and Marine Engineering paper) leads to M.Tech and PSU/shore jobs; a COC comes only from DGS examinations backed by approved sea service.

Common mistakes

• Treating the CDC or a college degree as the licence — only the DGS-issued COC entitles you to a rank.
• Assuming an average above the pass mark clears the written stage; each paper must be passed separately, and failed papers must be re-sat.
• Accumulating sea service on ships below the required propulsion power, or with testimonials that omit the kW rating, ship type and dates — such service is rejected.
• Quoting sea-service periods, fees, attempt gaps and syllabi from old coaching notes: these are set by current DGS circulars and have changed more than once.
• Letting the written-pass validity or the STCW course validities lapse while repeating orals, so the whole written stage has to be redone.
• Confusing Class II and Class I scope, or thinking Class I is needed for Second Engineer — it is Class II for 2nd Engineer and Class I for unlimited Chief Engineer.
• Walking into the oral without knowing your own ship's machinery data, drawings, clearances and statutory certificates — examiners question from your actual service, not a textbook.
• Forgetting that tanker and high-voltage/management endorsements are additional requirements, not automatic with the COC.
