"It has been established that two jack-up rigs "Petro Hodovanets" and "Ukraina" illegally seized by the Russian Federation in 2014 during the annexation of Crimea have been moved out of the Odesa gas field area closer to the peninsula (their whereabouts to be revealed)," the statement notes.
"Ukraine's Sea Guard ship has registered the fact of gross violation of the norms of international maritime law and the law of Ukraine on the exclusive (maritime) economic zone of Ukraine. The concerned ministries and departments have been notified of the violation of international maritime law and Ukraine's legislation. The Ministry of Foreign Affairs is preparing a note of protest which will be officially filed with the Russian side," the service adds.
As previously reported, Chernomorneftegaz (Simferopol) said the movement of the two platforms from the Odesa gas field area to Crimea's coastal waters in late November was due to an increased terrorist threat.
