Reuters has no independent confirmation the equipment on the dock was Siemens-made turbines. It comprised four cylindrical objects, several meters long, and covered with blue and gray tarpaulins.
Their dimensions and shape match publicly-available photographs of Siemens gas turbine systems, which each consist of two major components: the turbine itself and a generator.
Siemens said earlier this week that at least two of a total of four turbines it sold to Russian state firm Technopromexport had been delivered to Crimea against its wishes and without its knowledge. Russia seized the region from Ukraine in 2014 and it is now subject to European sanctions on energy technology.

Taman, in southern Russia, is not subject to sanctions.
On Wednesday, Yashar Azad, a spokesman for Siemens at its Bavarian headquarters, said the company was still trying to establish all the facts, including the location of the two other turbines and had nothing to add to its previous statements.
Technopromexport, the Russian state company building the Crimean power plants, and Russia's energy ministry, declined to comment.
Asked if the pieces of equipment at the port were Siemens turbines, a government official in Crimea told Reuters: "Come on, we can't talk about that. You understand: sanctions, Siemens."

If the equipment seen by Reuters reporters at the quayside in Feodosia are Siemens-made, it would show that Russia is pressing ahead with its plan despite the Siemens lawsuit and a warning this week from the German government that the use of Siemens turbines in Crimea could harm future German investment in Russia.
Siemens said on Monday it did everything possible to ensure compliance with sanctions.
Russia needs four turbines in total for new power stations on the Crimean peninsula, which Ukraine cut from its electricity grid after it lost control, according to three people close to the project who spoke to Reuters.
Two of the turbines are for a power plant under construction in the city of Sevastopol, and the other two for a plant being built in Simferopol, they said.
