The Merchant Navy is often described as the backbone of global trade. Almost 90% of world trade is carried out by ships, transporting goods such as oil, coal, food, cars, and raw materials across oceans. Unlike the defense navy, which serves a country’s military interest, the merchant navy is a commercial fleet that ensures the smooth functioning of international commerce.
For those with a sense of adventure, love for the sea, and the ambition to earn a high-paying international career, the Merchant Navy offers a promising pathway. However, it isn’t as simple as boarding a ship and starting work. Candidates must meet specific merchant navy qualifications—covering education, age, health, and professional certifications.
This article will serve as your step-by-step guide to understanding every qualification requirement for joining the Merchant Navy, whether you want to start as a deck cadet, an engineer, or eventually become a captain.
