KYIV, Sept 16 – The gas transmission systems of Ukraine and Slovakia are ready to help Russia's Gazprom with delivery of the required volumes of Russian gas to Europe, replacing the services of the OPAL pipeline, Chairman of Executive Board of Naftogaz Ukrayiny Andriy Kobolev said.

"If Gazprom wants to continue delivering these volumes of gas to where they went via OPAL, but in a shorter way, the Ukrainian and Slovakian gas transmission systems can easily do this. As they did before Gazprom gained exclusive access to OPAL," he wrote on his Facebook page.
