In view of the severe ice situation in the Gulf of Finland in winter navigation of 2010-11, Russia decided to secure itself by sending nuclear icebreakers to assist diesel-electric ones in the Baltic Sea. Meanwhile, operation of one nuclear icebreaker being equal to that of a diesel-powered open sea icebreaker costs 4-5 times more. In case of oil price fall, deployment of nuclear icebreakers will become economically impractical. Engaging of icebreakers from Finland is under consideration.
