Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, pursuant to the Answer of 8 February 2023 to Question 139285, whether the classification of within territorial waters relates to the siting of the specific installation.

The specific installation is a mobile installation, specifically a jack-up drilling rig. It had been engaged in drilling work at a field on the United Kingdom Continental Shelf (UKCS) over 100 miles east of mainland Scotland. When that work was completed the rig was towed to the port of Dundee. The territorial sea is defined by The Territorial Sea Act 1987 which are waters adjacent to the United Kingdom coastline and cover a breadth of 12 nautical miles.
