Seafarer Medical Examination: Ensuring Fitness for Life at Sea
A career at sea is both adventurous and demanding. Seafarers are responsible for navigating ships, operating complex machinery, and ensuring safety in challenging maritime conditions. Because of the physical and mental demands of this profession, every seafarer must undergo a Seafarer Medical Examination before joining a vessel — and regularly thereafter.
In this blog, we’ll explore what the seafarer medical examination is, why it’s important, what it includes, and how to prepare for it.
What Is a Seafarer Medical Examination?
A Seafarer Medical Examination (also called a Seafarer Medical Fitness Test) is a mandatory health assessment required by international maritime regulations. It ensures that seafarers are medically fit to perform their duties at sea without posing risks to themselves or others.
This examination is conducted according to standards set by the International Maritime Organization (IMO) and the International Labour Organization (ILO) under the Maritime Labour Convention (MLC, 2006) and STCW (Standards of Training, Certification and Watchkeeping) requirements.
A valid Seafarer Medical Certificate is necessary for employment on any commercial vessel.
Why Is It Important?
Working at sea presents unique challenges — long hours, isolation, limited medical facilities, and exposure to extreme weather. A medical emergency in the middle of the ocean can have serious consequences.
The seafarer medical examination helps:
-
Ensure safety: Prevents accidents caused by medical conditions like fainting, poor vision, or chronic illnesses.
-
Protect crew health: Identifies contagious diseases that could spread onboard.
-
Meet legal requirements: Every shipping company must comply with international maritime health standards.
-
Promote wellbeing: Encourages early detection and management of health issues.
Who Needs a Seafarer Medical Examination?
All personnel working aboard seagoing vessels must undergo the exam, including:
What Does the Examination Include?

How Long Is the Certificate Valid?
Typically, a Seafarer Medical Fitness Certificate is valid for two years, but younger seafarers (under 18) may need annual examinations. Some conditions may also require more frequent check-ups.
How to Prepare for the Exam
Here are some practical tips to ensure a smooth medical assessment:
-
Get enough rest the night before.
-
Avoid alcohol or fatty foods 24 hours before the test.
-
Bring necessary documents — ID, previous medical certificates, and vaccination records.
-
Inform the doctor about any medications or chronic conditions.

In certain cases, waivers may be granted depending on the severity and management of the condition.
Conclusion

Regular medical check-ups not only protect individual health but also contribute to the overall safety and efficiency of maritime operations.
