A Russian missile cruiser and a coast guard powerboat had to intervene after a merchant vessel flying the Turkish flag hampered a Russian convoy transporting two drill platforms to a new location in Russian territorial waters.

The decision to relocate them closer to Crimea was caused by the complicated international situation, according to a press release from the Russian Chernomorneftegaz state company that owns the platforms.

While the two rigs were being moved to their new location, a vessel under the Turkish flag crossed the convoy’s path.

Chernomorneftegaz said in a statement, that the captain of the Turkish vessel operated radio silence despite requests to respond.

The incident was “resolved” when a powerboat from the Russian coast guard and a missile cruiser came to the aid of the Russian convoy and chased the Turkish vessel off.

The company says the B-312 and B-319 rigs are worth 25 billion rubles (about US$357mn). Both rigs have reportedly being safely brought to Russian territorial waters.
