Aug 18 (Reuters) - Kazakhstan could redirect oil exports to Russia's Baltic Sea port of Ust-Luga instead of Novorossiysk, if the situation on the Black Sea deteriorates, the deputy head of state oil pipeline company Kaztransoil said on Friday.

Kaztransoil's Erik Sagiev said during an online briefing: "If the situation in the Black Sea worsens, the volumes that we transport in the direction of the port of Sheskharis (in Novorossiysk) will be transferred to the port of Ust-Luga".

Novorossiysk, Russia's largest Black Sea port, handles the bulk of Kazakhstan's oil exports via the Caspian Pipeline Consortium.

Earlier in August, navigation in the port's waters was briefly banned after a naval drone strikeand Ukraine has threatened further such attacks if Russian air strikes on Ukrainian ports continue.
