"Twenty on the right side."

"Twenty right-hand rudder!"

"Twenty degrees right!"

The helmsman turns the rudder, engrossed and sophisticated.

Searchlights illuminated the land, the bridge was filled with the sound of harmony, and Captain Harvey's voice was raised to ensure that every command was carried out accurately.

Almost 100% of the ships were able to turn upside down, but unfortunately, the course hundreds of meters behind it had been frozen, and for safety, the Tesis had to turn its bow to sail out of the ice field and merge into the sea with the gray whales.

In addition, the average driver will not choose to reverse, and the rules of sea collision avoidance recommend that the driver's collision avoidance method is almost always to slow down and steer, unless encountering an urgent situation or collision danger will think of emergency braking or reversing - because this will hurt the machine.

A correct but unnecessary decision was exchanged for a few days and nights of overtime and contempt by the engine department, if even the engine department could not be solved, and it would be towed to the shipyard by tugboat for repair, and hundreds of thousands of ugly gold would be cheap.

The worst case scenario is that if the tugboat can't get in the middle of the ocean or ice area where there is no village in front of the village and no shop in the back, the 300 or so people on board can only cry.

This head must be adjusted.

Harvey knew that turning the bow of the ship on the ice was a technical task, and it was very likely that it would roll over or damage the hull, so he must not be negligent, and he stared at the dashboard and the ice, and there was a rare sense of tension.

From the day he walked out of college, Harvey stepped on an ocean-going ship and drifted on the vast sea until now, dedicating all his youth to the sea.

From the second officer to the first officer, from the technical level to the management, and then to the current captain, it is a testimony of the passage of time and efforts.

To outsiders, the profession of a seafarer seems to be quite glamorous, sailing and circumnavigating the world, and whenever he returns with a full load of harvest and enters the tavern, there is always a large crowd of people sitting around to listen to his interesting stories about the sea.

But in fact, the seemingly beautiful sea is full of dangers, especially in the Arctic Ocean.

Icebergs are alive.

Captain Harvey is convinced.

Sometimes it's 99% underwater, just on the surface of the sea with a sharp tip exposed.

Even normal people can see this picture calloused in their eyes, but it's not a joke when you really encounter it.

At present, the navigation aids on most ships cannot scan anything under the surface of the water in the bow, and you think that the point is passable......

Secondly, the iceberg is not fixed like other coastal references, it will move!

Whether it's ice or icebergs, they move, and the main driving force of movement is wind, followed by ocean currents.

Under the influence of wind speeds, some can even reach a speed of 44 kilometers per day, which can transport certain objects on land and even live animals and plants from their source areas to thousands of kilometers away.

Scholars who specialize in this field can deduce the distribution of glaciers 10,000 years ago by looking directly at the sediments in the ocean.

In the dead of night, Captain Harvey often dreamed of such a vision: the ship was driving and suddenly full of icebergs, completely surrounded, and still slowly approaching him, whether it was reversed or slowed down, nothing could be done, and he woke up in despair, feeling extremely bad.

Later, the Tesis became an icebreaker, and there were many fewer nightmares like this, after all, the armor was stacked, but it still couldn't be taken lightly.

It can only be said that there are threats everywhere.

As the captain of the ship, Harvey is always walking on thin ice, shouldering the safety of the entire ship, the lives of dozens of crew members and hundreds of passengers, and the families behind them.

Bringing his brothers home alive was the only thing Harvey had always hoped for.

It's going to be successful!

Nearly sixty years old, Harvey felt his long-lost blood rekindled, and his heart was tense and excited, and he picked up the brewed coffee, trying to relieve some of the fatigue caused by the long hours of work.

The navigator on the side handed over the ice box and asked if he wanted to add ice cubes.

Harvey laughed: "Of course you have to add!" I love ice cubes. However, I only like the one in the cup, not the one in the sea. ”

As an ocean-going seafarer, every time you go to sea, you are committing your life to the sea.

Fighting against the wind and waves, dangers are everywhere.

In the confrontation between man and nature, it is only a good wish that man will conquer the sky.

Compared to the great nature of nature, the power of human beings is simply too small. But no matter what, only by being in awe of nature, being indomitable, and remaining optimistic and strong can we survive and create miracles!

"Captain, I can already see them!"

"Is that the second officer? He's waving at us! ”

"Success is just around the corner, concentrate, jump the bow of the boat, and do it one last time!"

"Come on!"

The headlights of the Tesis shone directly above the clearing, reminding Bi Fang of the days when he first came to the North Pole, and he couldn't help but think of the day, as if it had become a distant word.

A third of the 100-day mission has passed, and I didn't expect it to be so exciting.

After collecting his thoughts, Bi Fang came back to his senses and did not continue to dig a hole, but expanded the area of the ice cave on the original foundation to make it easier for the whales to breathe.

Generally speaking, the tactical radius of a quick rudder turn is less than 5 times the length of the ship, and if the aspect ratio is small, it will be smaller, but on the ice field, this tactical radius should be extended a lot to avoid the sideboard collision with the ice.

The overall strength of the icebreaker is much higher than that of ordinary boats, but the hardest part is still the bow, and if you can hit it with the bow, try not to use other parts to avoid displacement.

By the time the Tesis was completely crossed, the distance between the two sides was less than 100 meters, which was almost the level of veneerality.

At this distance, the gray whale can also directly see the huge expedition ship, and the frequency of air exchange has increased significantly, which is obviously a sign of emotional excitement.

The three big guys are frighteningly smart.

Turning in a large circle, the Tesis made a quick turn while the sea ice behind it was still not freezing, and returned to its original normal.

Everyone breathed a sigh of relief, and the next step was to go back the way they came!

It is true that the original channel was frozen, but the new ice was not as hard as the old ice in terms of hardness and thickness, so in the case of the pursuit of speed, it was natural to try to choose a trouble-saving method.

In the wee hours of the morning, it was a sleepless night for all those who were at the same longitude, because tonight was the day when the gray whales began to follow the Tesis out of the ice!

The collision of steel and ice carved a way out for the three-headed beast.

At 1:10 a.m., the Tesis returned to its original orbit.

At half past one, the Tesis had advanced a hundred meters, leaving enough space between the ice and the ocean.

The snow on the ice field was cleared, several Xiaoice caves became signal signs, and under the leadership of Bi Fang, the three big guys swam slowly under the ice, and the huge wide tail rolled up dozens of tons of seawater, bringing enough thrust to follow behind the Tesis.
