In the first week of the "ceiling" and the ban on sea deliveries of Russian oil, exports from Russia decreased by 54%, according to Bloomberg, based on data on tanker movements.

One of the reasons for this drop is technical work at the key port of Primorsk on the Baltic Sea, where shipments have been reduced to three tankers per week, while the normal weekly figure is eight tankers.

In the oil port of Kazmino (Znahodka Bay, Far East), only two tankers were loaded during the week.

On average, eight tankers are loaded here, as well as in Primorsk, per week.

At least two major tanker owners have withdrawn their ships from the route as oil is selling at prices above the "ceiling" prices.

Carriage of cargo may deprive the ship of international insurance.

Bloomberg indicates that flow from Cozmino will resume, at least partially, as three ships are already loaded and two more are docked.

However, given the smaller fleet, volumes may remain volatile.

The publication writes that these data should be treated with caution, as the weekly currents also depend on the terms of cargo transportation planning, the weather, and even on the quality of the signals transmitted by the ships themselves.

On December 5, a ban on sea deliveries of Russian oil to EU countries and a price "ceiling" of $60 per barrel for oil from Russia transported by sea came into force.

The restrictions were agreed by the European Union, the G7 countries and Australia.

Russia responded by saying that it would not comply with this limit, even if it had to cut production.

The introduction of the limit price for Russian oil, as Reuters wrote, forced Moscow to look for alternative sales markets, mainly in Asia, for approximately 1 million barrels per day.

According to the agency, in December Russia sold Urals oil to India well below the limit price of $60.
