ENG-1 is the mandatory DG Shipping-approved seafarer medical fitness certificate, valid for 2 years (1 year over age 55), covering vision (6/6 deck, 6/12 engine, with mandatory Ishihara color test), hearing, cardiovascular fitness, blood tests, and zero-tolerance drug screening. Vision and color blindness are the #1 rejection cause — test this before committing to any maritime career path, since a colour-blind result permanently closes the deck officer route.
The ENG-1 medical certificate is non-negotiable. No ENG-1, no sea service. Period.
What Is ENG-1?
ENG-1 is the seafarer’s medical fitness certificate issued by a DG Shipping approved doctor. It certifies you are physically and mentally fit for sea service. Valid for 2 years (1 year for seafarers over 55).
What the Medical Covers
Vision — #1 Rejection Cause
Deck Officers:
- Distant vision: 6/6 in one eye, 6/9 in the other (with or without correction)
- Colour perception: Must pass Ishihara test — check this BEFORE choosing maritime career
Engine Officers:
- Distant vision: 6/12 in each eye acceptable
- Colour perception required but less strict than deck
Hearing
Must hear forced whispered voice at 3 meters in each ear. Hearing aids generally not accepted.
Cardiovascular
- Blood pressure within limits (systolic <160, diastolic <100 typically)
- ECG for candidates over 40
Blood Tests
- CBC, fasting glucose, HIV, Hepatitis B&C (company dependent)
- Drug screening — zero tolerance (cannabis, opioids, amphetamines, cocaine)
Psychological
History of epilepsy or serious psychiatric disorders assessed.
How to Prepare
3 months before:
- Get colour vision test at any optometrist — don’t discover a problem at the exam
- Start cardio exercise
- Stop smoking (lung function test)
- Stop recreational drugs entirely — traces remain for months
1 month before:
- Get glasses/contacts sorted if you need vision correction
- Control blood pressure if it’s been high
- Avoid heavy alcohol 48 hours before
- Fast 8 hours before if blood glucose test included
DG Shipping Approved Doctors
Only doctors on the DG Shipping approved panel can issue ENG-1. Find the list at dgshipping.gov.in → Seafarers → Medical Examination. Cost: ₹2,000–₹5,000 depending on city.
Failing ENG-1
Temporary unfit: Minor issues (high BP, healing injury) — re-apply after treatment.
Permanent unfit: Colour blindness (deck), uncontrolled epilepsy, severe heart disease. Engine/ratings roles may still be possible.
Restricted fitness: “Fit for engine room only” or “not for watchkeeping” — limited career scope.
Renewal
Set a reminder 3 months before expiry. A lapsed ENG-1 = no sailing. Companies repatriate you immediately. Renewal requires the full examination again.

Fitness Training for ENG-1
Beyond the clinical tests, being physically fit helps with recovery from borderline results. Specific exercises:
Cardiovascular health:
- 30 minutes brisk walking or jogging daily reduces resting blood pressure by 5–8 mmHg over 8 weeks
- Helps with treadmill/exercise ECG if required
Vision maintenance:
- Screen time reduction before the test (less strain = better acuity)
- Ensure spectacles/contact lens prescription is current
Hearing protection:
- Use ear protection in engine rooms — long-term noise exposure causes progressive hearing loss
- Avoid loud music exposure in the month before the exam
A physically fit seafarer rarely fails ENG-1 on clinical grounds. The most common failures are preventable: colour blindness (discovered too late), substance use, or unmanaged blood pressure.

Frequently Asked Questions
What's the single most important thing to check before starting maritime training?
Your color vision (Ishihara test) at any optometrist, before enrolling in anything — colour blindness is a permanent disqualifier for the deck officer route specifically, and discovering this after investing in training is a genuinely preventable, costly mistake.
How long is ENG-1 valid, and what happens if it lapses?
2 years (1 year if you're over 55). A lapsed ENG-1 means no sailing — companies repatriate you immediately, and renewal requires the full examination again. Set a reminder 3 months before expiry to avoid this.
