MOSCOW, Nov 27 (Reuters) - Russia's oil and oil products exports from the Novorossiysk Black Sea terminal are being restricted as bad weather has caused significant delays to loadings, two sources familiar with the port's operations said on Monday.

The Black Sea region has been hit by heavy storms since Friday, disrupting logistics and damaging homes and infrastructure.

"It's a mess in the port. The terminal has opened several times for short periods, but no real progress in loadings was made," one of the sources said.

Some oil tankers have been waiting to sail since early November, the source said.

The second source said that he expects a large volume of crude oil scheduled for loading this month to be carried over to December.

The November oil loading plan for Novorossiysk was initially set at 2.42 million metric tons. More than 1 million metric tons of this volume was delayed, according to one of the sources.

Bad weather in the Black Sea has also increased the time of passage through the Turkish straits, Bosphorus and Dardanelles, the sources said. A round trip via the straits now takes 12 days compared to about four days during the summer season, according to Riverlake agency data. <0#RIVERLAKE-STRT>

Russian oil pipeline monopoly Transneft said it had halted oil loadings from the port of Novorossiysk due to storms, TASS news agency reported citing a Transneft spokesperson.

The nearby Caspian pipeline consortium (CPC) terminal was also closed due to storms. CPC is a main export route for Kazakhstan's crude oil.
