Flag State Responsibility in Respect of MLC Requirements

Traditionally, jurisdiction over a ship has been connected with its nationality. The ascription of nationality to ships is one of the most important means by which public order is maintained at sea. The nationality of a ship is that of the State in whose register of ships it is entered. By placing a ship on its register, a State assumes the authority to exercise over the ship and undertakes the national and international responsibilities of a flag State in relation to that ship.
