Novatek's Yamal LNG project may temporarily lose one of its Arc7 ice-class tankers, the Nikolay Evgenov, which is currently completing its passage through the Northern Sea Route without an icebreaker escort. According to Kommersant, the ship broke down one of the three azipods - propulsion systems, but the tanker continues to move at reduced speed and has almost completed the passage of the NSR. The ship may require either repair or replacement of azipods, in the latter case the tanker will have to be docked for about a month. In addition, the reduced speed is likely to lead to shipment delays and penalties. Novatek did not provide any comments.
