Question to the Department for Transport:

To ask the Secretary of State for Transport, how many of the oil and gas support vessels operating in the North Sea are (a) registered or flagged in the UK and (b) registered or flagged abroad.

As of December 2021, there were 149 UK Registered (flagged) vessels operating in the Oil & Gas sector accounting for 657,000 Gross Tons (GT). It is important to note that these vessels all hold certification to operate in and around the North Sea and their owners and operators have contracts specifically in the Oil & Gas sector.

The Government does not hold registration data for non-UK Flagged vessels specifically operating in the oil and gas sector.
