Seafarer Medical Examination: A Vital Step Before Setting Sail
Before a seafarer steps foot on a ship, there's one crucial requirement that must be met — the Seafarer Medical Examination. This examination is more than just a routine check-up; it's a comprehensive health screening that ensures all seafarers are medically fit to handle the unique challenges of working at sea.
Whether you're a new cadet or a seasoned officer, this guide will walk you through everything you need to know about the process.
? What is the Seafarer Medical Examination?
The Seafarer Medical Examination is a mandatory health assessment that all seafarers must undergo to prove they are fit for duties onboard. The test is required under international maritime conventions such as:
-
STCW (Standards of Training, Certification, and Watchkeeping)
-
MLC 2006 (Maritime Labour Convention)
The purpose is simple: to ensure that no individual poses a health risk to themselves or others while working in the demanding maritime environment.
?? Why is it Important?
Life at sea is physically and mentally demanding. You may face rough weather, long hours, and limited medical facilities. The medical examination is designed to:
-
Prevent health emergencies at sea
-
Ensure safety for the entire crew
-
Comply with national and international maritime laws
-
Detect and manage chronic or communicable diseases early
Without a valid medical certificate, you cannot legally join a vessel.

Every person working onboard a ship — including officers, ratings, catering staff, and cadets — must have a valid medical certificate issued by a recognized medical examiner.
Whether you're joining a cargo ship, tanker, cruise ship, or offshore platform, this is a non-negotiable requirement.
