Reuters was unable to determine if Siemens knew of or condoned the equipment transfer, but the move exposes the German company to potential accusations of indirect sanctions-busting and of not taking sufficient safeguards to ensure its equipment does not end up on territory most countries view as illegally annexed, say legal experts.
"Siemens has not delivered turbines to Crimea and complies with all export control restrictions," said Wolfram Trost, a spokesman for Siemens in Munich, when asked to confirm the turbine transfer to Crimea.
Citing client confidentiality, he did not answer written questions asking whether Siemens was aware that the turbines had been shipped to Crimea and whether it would now be activating or servicing them.
Russia needs the turbines for two Crimean power plants the Kremlin wants to get up and running to fulfill a promise, made by President Vladimir Putin, to ensure a stable power supply for the region's residents after it was annexed by Moscow from Ukraine in 2014.
