The innovation consists in the fact that half of the hull does not mirror the same. The left side gradually expands from the stem, and almost twice as rounded to the stern. Due to the special arrangement of the three rudderpropeller icebreaker can leave a channel width greater than the width of his body. A vessel of this type will be built in the world for the first time.
The fact is that when the tanker is much wider than the ice-breaker, it is necessary to attract second icebreaker. Asymmetrical breaker can be replaced by two large icebreakers. Because he can prodelyvat the ice channel, moving not only the nose, but stern.
If the breaker is in a very wide or large-vessel, he may turn to 30-45 degrees, and by combining the direction of flow of water to attack the ice across the board.
Icebreaker has a length of 76 meters and a width of 20.5 meters. The ship is moving at a speed of 14 knots, the speed of the ice thickness of 1 meter of 3 knots, the data contained in the presentation of an icebreaker Arctech Helsinki Shipyard. For comparison, a series of icebreakers "Arctic" are designed to move at a speed of 2-3 knots (4-5.5 km / h) in the ice thickness of 2.8 meters.
The vessel can also be used to combat oil spills in seas. It is equipped with a skimmer, which passes through the filtration of oil slick and the separation of oil from water.
Icebreaker can pass through ice up to 1 meter. However, through such thick ice breaker can carry out maneuvers only forward and backward. In a state of "oblique stroke" icebreaker can swim through the thick ice only 60 cm can cut through the ship channel is 50 meters wide, that is the channel width exceeds the width of the shell is 2.5 times.
It is planned that the ship will be launched in early 2014. The tests will take place in February - March 2014 in the Gulf.
