Seafarer Medical Examination: Ensuring Health and Safety at Sea

Life at sea is demanding — both physically and mentally. Seafarers work in challenging environments where immediate medical care is not always available. This is why maintaining good health is not just a personal matter but also a critical safety requirement in the maritime industry.

To ensure that all crew members are fit for duty, the Seafarer Medical Examination is a mandatory health assessment designed to evaluate whether a person is medically fit to perform their duties onboard a ship. It's an essential component of maritime safety regulations, governed by national and international standards, including the STCW (Standards of Training, Certification, and Watchkeeping) and the MLC 2006 (Maritime Labour Convention).


What is a Seafarer Medical Examination?

A Seafarer Medical Examination is a comprehensive health assessment conducted by an approved medical practitioner. It ensures that a seafarer is free from any medical conditions that could impair their ability to safely perform duties at sea.

Upon passing the examination, the seafarer is issued a Medical Fitness Certificate, which is required to board a vessel and is typically valid for up to two years.


Who Needs It?

  • All seafarers, including officers, ratings, engineers, cooks, and hospitality staff working onboard commercial vessels, offshore ships, cruise liners, and fishing boats.

  • Required before joining a vessel, renewing contracts, or attending maritime training courses.


Purpose of the Seafarer Medical Examination

  • To confirm the seafarer can perform routine and emergency duties without risk to their own or others’ health and safety.

  • To identify any pre-existing medical conditions that may worsen at sea or require regular treatment.

  • To prevent the occurrence of medical emergencies at sea, where access to care is limited.


What Does the Examination Include?

While the exact procedures may vary by country or authority, a typical seafarer medical examination includes:

1. Physical Examination

  • Height, weight, blood pressure, pulse

  • Heart and lung check

  • Abdominal examination

  • Musculoskeletal assessment

  • Vision and hearing test

2. Laboratory Tests

  • Blood test (CBC, sugar, cholesterol)

  • Urinalysis (to check kidney function, diabetes, infections)

  • Chest X-ray (for tuberculosis or lung issues)

  • ECG (especially for those over a certain age or with cardiac history)

3. Drug and Alcohol Screening

Some companies or authorities may require screening for substance abuse.

4. Mental Health Assessment

  • Evaluation of emotional and psychological well-being.

  • Particularly important due to the isolated and stressful nature of life at sea.


Validity of Medical Certificate

  • Most medical fitness certificates for seafarers are valid for 2 years.

  • For those under 18 years of age, the validity is typically 1 year.

  • In cases where certain health conditions are monitored, a certificate may be issued with a shorter validity period or specific restrictions.


Important Guidelines and Regulations

  • The MLC 2006 requires all seafarers to have a valid medical certificate.

  • STCW Convention also outlines the physical and medical standards necessary for safe maritime operations.

  • Each flag state (e.g., Panama, Liberia, Marshall Islands) may have additional specific requirements.


Preparing for the Medical Exam

  • Bring any previous medical records, prescriptions, and eyeglasses (if worn).

  • Avoid alcohol and caffeine 24 hours before the test.

  • Get enough sleep the night before.

  • Disclose any ongoing medical issues honestly.


What Happens if You Are Found Unfit?

  • If a health issue is detected, you may be temporarily declared unfit until further evaluation or treatment.

  • In some cases, a restricted certificate may be issued (e.g., not fit for work in certain departments like engine room).

  • You may also be referred to a specialist for further diagnosis or management.


Conclusion: Health at Sea is Safety at Sea

A Seafarer Medical Examination is more than a bureaucratic requirement — it’s a vital tool for ensuring the safety, well-being, and efficiency of everyone onboard. By confirming that each crew member is medically fit to perform their duties, ship owners, operators, and authorities contribute to safer maritime operations.

Whether you're a seasoned mariner or just beginning your career at sea, staying medically certified and in good health is one of the most responsible steps you can take. After all, a healthy seafarer is the backbone of a safe voyage.
