Part 1: Sanctions regulations Chapter 1: Power to make sanctions regulations Section 7: Shipping sanctions
Section 7 contains powers to control the movement of disqualified, designated or specified ships to prevent such ships from entering UK waters or, if they have already done so, to require such ships to leave or to be detained whilst enforcement action is taken.
	Disqualified ships are those which are registered in, fly the flag of, or originate from a prescribed (sanctioned) country. They can also be ships which are owned (wholly or partially), controlled, chartered, operated or crewed (wholly or partially) by designated persons, or persons connected with a prescribed country. A designated ship is one which has been designated by the UN. A specified ship is one which has been specified by the appropriate Minister. Provisions relating to specifying ships are set out at section 14.
	The Secretary of State may give directions to the master or pilot of a ship, or direct the relevant harbour authority to give such a direction. These directions can include, but are not limited to, directing a ship to leave the UK, to go to a specified harbour or not to enter the UK.
	This section allows ships to be refused registration on the UK Ship Register on the basis that a designated person or persons connected with a prescribed country hold an interest in them, or because it has been specified by an appropriate Minister. If a vessel is already on the UK Ship Register, this section provides it to be removed if those circumstances arise.
	The Secretary of State can also issue directions to a British ship anywhere in the world, in order to prevent it from entering a country in which relevant sanctions are in force.
