The 70 meter long, 3580 dwt ro-ro ferry Sanduga became disabled in the Sea of Japan.  The Sanduga was sailing from Busan, South Korea to Vladivostok, Russia loaded with vehicles when it suffered a mechanical failure.   Unable to fix the fault, the master of the vessel requested assistance.  The ferry Ryofu, owned by the same company as the Sanduga, responded to the scene and took the Sanduga under tow.   After a few hours, the towline broke and the vessels were unable to reconnect the line.  The owners contacted the salvage vessel Lazurit which arrived later and took the Sanduga under tow to Vladivostok.  No reports of injuries, damage or pollution being released.
