Chapter 404: 0 Mile Rescue

"Report! Level order!"
"Read!"
"The Maritime Department urgently notified that there was a fishing boat in distress in the southeast waters and requested rescue. Order your ministry to go for rescue as appropriate. Pay attention to weather changes..."
"position."
"Southeast, 370 nautical miles in a straight line."
"meteorological."
"The wave is four meters high. The gust is eighth."
The command is very simple. Is to save people. Before the tyranny of the tropical cyclone, bring people back as much as possible.
370 nautical miles to the southeast, it is still far away. It belongs to the Philippine Sea.
Note that it is just called the Philippine Sea. It is not the exclusive waters of the Philippines. It is the high seas.
Chinese fishing boats often come to this place to fish. From time to time, there will be some disputes with the fishing boats of the Philippines. This time too.
From the situation reported since then, it is the fishing boats of the two parties that had an interest dispute on the high seas, and then a collision occurred.
The Philippine fishing boat relies on its large tonnage and high horsepower.
China’s fishing boats are not vegetarian either. Fight back decisively.
The result is both losers.
Now both fishing boats have lost power. Can only wait in place.
Judging from the situation of satellite monitoring, the Philippines also has warships rushing to the sea area where the accident occurred. The straight-line distance is about 250 nautical miles.
The Jianzhou ship was 370 nautical miles away from the accident sea area. The difference between the two is about 120 nautical miles.
Must be on the scene before the other party.
For this kind of thing, whoever moves fast has always been beneficial.
If it was taken away by a Philippine warship. It will take a lot of effort in the future to bring his own people back.
If China had arrived first to take away the fishermen from the Philippines, we would have the initiative in the future.
A distance of 370 nautical miles, at a speed of 50 knots, can be reached within 8 hours.
The opposing warship was 250 nautical miles away, and at a speed of 30 knots per hour, it arrived in about 8 hours.
Time must be raced against.
Every second must be counted.
Even if they arrive at the scene one minute earlier, they can seize a favorable position.
All the staff officers were awakened and immediately carried out chart operations to plan the shortest route. It must be the shortest possible time to reach the accidental sea area.
The naval route of a warship in the sea is often not straight. In many cases, it will be specially rounded.
why? Mainly affected by the current sea conditions.
Such as ocean currents, trade winds, reefs and so on.
Reefs and the like may be well understood by everyone. What the is the ocean current?
In fact, the impact of ocean currents is still very large.
Sea water also flows. This is ocean current.
Ocean currents have directions. Drive downstream, fast and save fuel. Driving against the current, the slow speed also increases consumption.
There are also trade winds.
In the sea, the air flow is constant.
The airflow is strong to a certain extent, forming wind.
The wind of the sea has a certain pattern. At different times, there are different directions. This is the trade wind.
If you drive downwind, you can undoubtedly speed up and save fuel.
If it is driving against the wind, the result is naturally slow speed and a waste of fuel.
Combining various conditions such as ocean currents and trade winds can draw the most economical route. At the same time, make sure to avoid dangerous sea areas. Avoid rocks or something.
There are deep seas near the target sea area. There is no such thing as a reef. Mainly affected by trade winds and ocean currents.
If driving in a straight line, the negative impact will be greatest, but the distance will be the shortest.
If it is a detour for a certain distance, the fuel is the most economical.
"How far is the economic route?"
"450 nautical miles."
"The only way to go is straight."
"What about the Philippine warship?"
"The economic route is estimated at 380 nautical miles."
"it is good."
Obviously, taking the economic route is too far and it takes too long.
The Jianzhou ship is equipped with a Panshi 600 engine, so there is no need to consider fuel economy.
After a brief discussion, Gan Haoyan decided:
Drive against the wind.
Drive against the current.
Wang Bu watched quietly.
In other words, there are really many tasks undertaken by the Chinese soldiers.
The defense of the home and the country, rescue and disaster relief, all belong to them.
No, the weather is so bad now, with one order, you have to rush hundreds of nautical miles away to bring people back.
The command face is considered discretionary. In fact, where is it possible to discretion? Completely ignored.
Even Wang Bu'an felt that these two words were superfluous.
It's not a lofty moral character.
The main reason is that seeing one's own person in danger, not saving him, is definitely not the work of a gentleman.
Needless to say, even he has such a consciousness.
They have nothing to consider at all.
Save people.
Save people as quickly as possible.
It's that simple. It's so direct. Issues that do not need to be considered at all.
A few minutes later, the second command followed.
However, the class reminds the Jianzhou fleet to pay attention to the fact that after reaching the sea area where the accident occurred, it may cause certain diplomatic disputes. Please pay attention to the handling procedures.
The basic principles are rationality, profitability, and discipline. Neither overbearing nor overbearing.
Guan Hongru came later.
He wants to discuss with Gan Haoyan.
The weather conditions are really bad. With a gust of eighth and a wave height of four meters, they are all dangerous.
Of course, it is not a very fatal danger.
If a frigate can't resist even the eighth wind, it is a weak chicken.
The problem now is that tropical cyclones are strengthening and there is a tendency to become tropical storms. If it continues to strengthen, it will be a typhoon. The Jianzhou frigate is not an opponent of the typhoon.
The straight-line distance is 370 nautical miles. At a high speed of 50 knots per hour, it will take eight hours to arrive.
In eight hours, the most feared is the formation of a typhoon.
With the continuous strengthening of gusts, the current state of the frigate is not very good.
After all, it is a light frigate with a displacement of only 2,100 tons. It would be better if there were 3000 tons. No need to think about it at all, just gallop past.
"Master Wang, what do you suggest?" Guan Hongru asked cautiously.
"I suggest filling all eight pressurized water tanks to increase their own weight." Wang Bu'an said bluntly.
Guan Hongru asked with an expressionless expression: "The reason?"
Wang Bu'an replied calmly: "If the eight pressurized water tanks are fully filled, it can increase the weight of about 1,100 tons. The deck level will be reduced by about 0.6 meters. It is in the effective range of resisting wind and waves."
Guan Hongru turned to look at Gan Haoyan, "What do you think?"
Gan Haoyan nodded, "You can consider."
No one raised objections.
In fact, they also thought of opening the water pressure tank.
Of course there are benefits. That is to increase one's own weight. Increase stability. Can effectively fight gusts and waves.
However, there are advantages and disadvantages. It is also a more dangerous practice.
After all, the weight of the frigate itself has increased, the ship's side has also been reduced, and the waterline has been lowered.
In case of a huge wave, the entire warship may be rushed down.
What they considered before was to fill the four pressurized water tanks and increase their own weight by about 550 tons.
However, Wang Bu'an's suggestion is to directly increase the weight of 1,100 tons in one step.
There is no doubt that Wang Bu'an's suggestion is more risky.
However, from the perspective of driving, it must be so.
Otherwise, relying solely on its own weight of 2,100 tons will not be able to fight against increasingly strong gusts.
If you only increase the weight of 550 tons, the effect will not be too obvious.
Refueling tactics is a big taboo of military strategists.
The key is that after the increase in weight of 1,100 tons, the test on the power system will be more severe.
As the second responsible person, Wang Buyan must be responsible for the power system.
The key test of this long-distance sea trial is also the Panshi 600 power system!
"How is the power system?" Guan Hongru asked.
"It can meet the needs. I am responsible." Wang Bu'an replied affirmatively.
"Execute." Gan Hongru finally decided.
"Understand." Gan Haoyan ordered immediately.
The eight pressurized water tanks were slowly opened, and the surging sea water poured in frantically.
The waterline of the battleship gradually decreased. The deck is getting closer and closer to the sea. More and more waves hit the surface of the deck, washing the deck repeatedly.
The 100mm main guns on the front deck of the frigate were already wrapped in rain cloth.
Even so, the waves are constantly pouring onto it.
After a few minutes, the valve closed.
The eight pressurized water tanks have all been filled with sea water.
Now, the weight of the Jianzhou ship has increased to about 3,200 tons, and its stability has increased significantly.
Its previous draft was only 3.2 meters, but now it has increased to about 3.8 meters. The deeper the draft, the better the stability of the ship. The stronger the ability to resist storms and waves.
For the power system, the burden is increased by more than 50%. This burden has increased exponentially.
Fortunately, the Rock 600 engine has enough surplus power.
Ships Qinzhou and Weizhou also executed orders to fill the pressurized water tanks.
"set off."
"Start~EbookFREE.me~The three frigates continue to march forward bravely.
The speed continues to increase.
25 knots...
30 knots...
35 knots...
40 knots...
Gan Haoyan paid close attention to changes in weather.
As the tropical cyclone gets closer, the weather is getting worse and worse.
Wave heights occasionally reach five meters.
Occasionally, gusts can exceed ten levels.
For warships, such storms are acceptable.
Especially the current Jianzhou ship, with its own weight of 3,200 tons, no longer needs to be afraid of level ten gusts.
However, for a fishing boat in distress far away, that is a big deal. A fishing boat that loses power can easily be destroyed by a storm. In other words, the people of the boat are in danger at any time.
Every second counts!
Time is life.
Must be at the scene of the accident in the shortest possible time.
"Chief Engineer Wang, we hope to increase the speed to 50 knots..." Gan Haoyan said expectantly, "You see if it is feasible..."
"No." Wang Bu'an shook his head flatly.
"why?"
"The mechanical rigidity is not enough. There is a risk of rupture. The maximum can only be 45 knots."
"Is it only 45 knots?"
"Yes."
"Ok."
Both Guan Hongru and Gan Haoyan are very sorry.
It's really a pity that it can't be raised to more than 50 knots.
However, Wang Bu'an is a technical engineer, and they must listen to professionals.
After all, the Rock 600 power system is from the 220 Institute. Wang Bu'an is the representative sent by the 220 Institute. Is the second responsible person. He is also very responsible.
The power system is indeed no problem.
However, the hull is really prone to accidents.
