The UK does not detain Russian vessels under sanctions, as their maintenance can cost tens of millions of pounds. This was reported on April 10 by The Times newspaper.

"The Royal Navy has not detained any of the sanctioned Russian oil tankers due to concerns that the cost of mooring and servicing the vessels could reach tens of millions of pounds," the publication says.
