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.

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.
