Since the previous century, maritime trade has experienced a strong development linked to the growth of world trade. Maritime transport is the most common mode of transport for the transport of goods. This mode of transport covers most raw materials (petroleum, ore, coal, cereals, phosphate, etc.). Today, 90% of the goods produced and consumed in the world are transported by sea. Without it, trade from one continent to another, the transport of raw materials and the transport of finished products at reasonable costs would be impossible. . Almost 50,000 merchant ships navigate in international waters and transport all types of goods. The world fleet is registered under more than 150 different flags, and operated by more than one million sailors of all nationalities.
