When Siberia shivers it's time to fix ships in the ice

When the Siberian winter bites and the Lena River freezes, dockworkers of the Yakutsk shipyard brace for a backbreaking but vital task - 'vymorozka'. With such short summers in Siberia, ships must be kept moving while the river, the economic lifeblood of the region, is passable. This means repairs must be done in winter when the river is frozen and the ships wedged tight in the ice.
