The Directorate general of shipping (DGS), under the ministry of ports, shipping and waterways has rolled out an important update for all Indian Seafarers. According to the new framework, all seafarers with an INDoS number must go through a standardized set of medical examinations or officially known as “Investigations” and secure a medical fitness certificate from the DGS-approved Medical Examiners.
This official move aims to regulate healthcare examinations for the employees to ensure consistent, transparent and preventive methodologies to secure their health and make them a proper fit for the demanding life at sea.
In today’s blog we will see:
WHY ARE MEDICAL TESTS FOR INDIAN SEAFEARERS MANDATORY?
Working for the maritime industry can be challenging, the field of work demands a lot of physical and mental strength. Long hours, physical strain, isolation and limited access to healthcare can be contributing factors. The executive office noted that until recently there were inconsistencies with how the investigations were conducted, leading to several undetected health conditions, putting both seafarers and vessels at risk.
This new update aims to:
- Detect hidden or early-stage conditions
- Ensure proper and timely treatment before deployment
- Keep ships, workers and the vessels safe and functioning.

WHO IS THIS FOR AND WHO DOES THIS AFFECT?
The rules from the original curricular applies to ALL INDIAN SEAFARERS with an INDoS number, regardless of:
- The type of vessel they belong to (coastal or international)
- The flag of vessel
- Their rank or role onboard
This new framework adds to the key features of maritime labor convention, 2006, ensuring the healthcare standards for the people that work tirelessly to contribute to the industry.
It is crucial to note that only Directorate general of shipping approved examiners/professionals are allowed to conduct these tests and issue certificates.
