How did the Snow Dragon break the ice?

1. Breaking the ice at the bow: It can be seen that an icebreaker is different from an ordinary ship. It doesn't have a big ball nose to overcome the wave resistance. On the contrary, it has a blade like a knife. When the ship is moving forward with strong power, these ice cubes are shattered by the impact force. For an ice-class icebreaker like Snow Dragon, half a meter of ice is too tender. However, handling thick ice requires the following methods.

2. Impact to break the ice: Generally, icebreakers have strong power and reinforced bows to sail in the ice area and impact large blocks of ice with kinetic energy. When the ship started at full speed, it rushed to the ice with its pointed and upturned bow and rode on the ice. After the ice layer could not bear the weight of the ship, the ice layer was smashed, and the ship seemed to become a shell with a small speed but a large mass, a hammer. The channel came out. Icebergs several meters high, the icebreaker must hit them several times with a solid bow to break them. However, due to the cold, the floating ice quickly condenses on the channel, and the ice layer is loose, so the ships behind can move along the channel of the icebreaker together.

3. Gravity breaking ice: The underwater part of her bow is very inclined to break ice. Sometimes, the icebreaker rushes to the ice and can't get down by itself. What shall we do? In order to strengthen our strength, the ballast water in the icebreaker's water storage tank works. So the special ballast water adjustment on board began. The powerful ballast water moved from the back to the front, concentrated all the gravity and crushed the ice. Sometimes it is difficult to ride a tiger and the ship can't get off when the ice cracks. The captain can order the pilot to transfer the ballast water on the port side to the starboard side to suppress the ice, and then transfer it to the port side when the ice cracks. Swinging from side to side broke the ice. So the speed of the icebreaker is very slow, and sometimes it takes only a few hours to sail for tens of meters.
