Chen Yuan's big fish is still installing equipment and replacing the host, and it is estimated that it will be the end of the month until the end of the month.

The next day, Lin Xinhai was fine, and took Zhao Hai and them to see the fishing boat.

Chen Yuan, Zhou Sheng, and Luo Laosi began to test Dabai's fuel consumption.

Far Star 55, long, 16.5 meters.

Width, 4.35 meters.

Engine, 700 hp X3.

Fuel capacity, 7000 liters. Reserve fuel tank, 500 liters X3.

High-speed cruising, about 44 knots, fuel consumption of about 300 liters per hour. The fuel consumption per nautical mile is about 6.8 liters.

Three-engine economy cruise, speed 35 knots, fuel consumption of about 193 liters per hour. The fuel consumption per 1 nautical mile is about 5.5 liters.

Twin-engine economy cruise, speed 27 knots, fuel consumption of about 130 liters per hour. The fuel consumption per nautical mile is about 4.8 liters.

Single-engine economy range, speed 17 knots, fuel consumption 80 liters per hour. Fuel consumption of 1 nautical mile, 4.7 liters.

The single engine looks the most fuel-efficient, but the savings are not much. Moreover, the single-engine mode has a relatively large loss on the engine.

The most cost-effective is the twin-engine economy cruise.

Anyway, Dabai is an oil tiger, and he eats oil very well.

Full oil, 8500 liters.

It maintains the economic working state of the twin engines, and can work continuously for 65 hours.

The reserve fuel tank of Big Fish has 23 cubic meters, that is, 23,000 liters, which can support Dabai for 177 hours of work.

Big White is Far Star 55, and Big Fish is a longline fishing boat.

Dabai is responsible for finding fish, and it is fast. The fastest speed of a big fish is estimated to be 23-25 knots.

Fishing boats rarely reach speeds of more than 20 knots. The speed exceeds 20 knots, and the fuel consumption is a straight line.

Chen Yuan: They also have a refrigerated ship, and the reserve fuel tank is 100 cubic meters + 95 cubic meters.

100 cubic meters of oil for fishing vessels and 95 cubic meters of diesel fuel in reserve.

"Dabai's fuel consumption really killed the old immortal, and it's too scary." Luo Laosi looked at the fuel consumption calculated by Chen Yuan, and his brain was numb.

Even if it is an economic cruise, during fishing, Dabai runs for 5 hours a day, which is 560 kilograms of diesel. If the search for fish is not smooth, it is easy to use up 1 ton of diesel a day.

There is also the boat of the big fish, which is also an oil tiger.

The upper limit of the host power is 2900k.

1 meter horsepower (horsepower) = 0.735 kilowatts (k), which means that the big white is almost 2100 horsepower.

The marine main engine is usually said to be kilowatts, and the fuel consumption depends on the fuel consumption rate of the main engine, that is, how many grams of fuel are consumed per kilowatt per hour.

The general unit is g/

Most marine engines within 1000k have a fuel consumption rate of about 200g/. If you follow this calculation, 1000k power, the fuel consumption per hour is 1000 times 200, which is about 200 kg of fuel consumption.

Of course, fuel consumption is subject to actual use.

Different main engines, fuel consumption rates are different, the more expensive the main engine, the lower the fuel consumption rate. There is also a large main engine, and the fuel consumption rate is also low. A low fuel consumption rate does not mean less fuel consumption. This is going to turn on the power ......

For example, the sixth-generation 400,000-ton ultra-large ore ship, the main engine of the ship is rated at 32,970 kilowatts, and the fuel consumption rate is about 105 g/kWh.

The daily fuel consumption of a ship is the rated power of the main engine multiplied by the fuel consumption rate, and finally multiplied by 24 hours, which is about 80 tons.

The upper limit of the host power of Dabai is 2900k, and it should be said that the upper limit of the total power is 2900k.

Dabai has a main engine, a standby machine, and an independent generator, with a total power limit of 2900k.

After all, Dabai's main fuel tank is only 139 cubic meters, which is about 123 tons of oil. ….

If you are just in a hurry, with low load, Dabai's daily fuel consumption is estimated to be 2.5 tons.

this

The upper limit of the main engine power of the original configuration is only 1000k, so the main fuel tank of 139 cubic meters is completely sufficient.

Now that a lot of upgrades have been made, the main fuel tank of 139 cubic meters is not enough.

Actually, it's enough for Big Fish to have a 1000k host. To replace the main engine, the most important consideration is to take into account the motor boat of Dabai.

Big white is an oil tiger, and big fish also have oil tigers, and there is a frozen boat......

Return to the gate slope, big white docking.

Outside the original ship repair yard, Lin Xinhai was sitting in the shed drinking tea, when he saw Chen Yuan and them coming back, he walked over: "How about the fuel consumption of economic cruise?"

"What an economic cruise, it's not economical at all. The cheapest is about 4.8 litres per nautical mile." Luo Laosi shouted.

"1 nautical mile, 4.8 liters?" Lin Xinhai also had a pain.

Yacht oil is not the same as marine oil.

Oil is much more expensive on yachts.

At present, the price of oil in China is 31.5 yuan for 1 nautical mile.

But it's okay, even if you run 300 nautical miles a day, that's ...... 9500 yuan?

Lin Xinhai calculated again, and shouted in his heart.

And if you add the big fish and the babysitter......

The nanny is the name of the frozen ship, and the frozen ship they bought has some of the functions of an auxiliary ship. The name 'Nanny' couldn't be more appropriate.

Lin Xinhai doesn't know how much it costs every day, anyway, there are a lot of them.

"Zhao Hai, did they choose a fishing boat?" Chen Yuan took out a cigarette and handed one to Lin Xinhai and Luo Laosi.

"Selected, a YJ50."

Fishing boat category, J is a tuna longline fishing vessel.

"How big?" Chen Yuan asked.

"45 meters. The largest ship in the YJ50 is 680 tons." Hayashi Shinkaido.

"A 45-meter longline is a lot of money."

"The boat is in average condition, 11 million in total."

"11 million." Zhou Sheng took a deep breath and said, "Actually, we should also buy a big boat."

"That ship is going to be sent to the shipyard for repairs, and it is estimated that it will cost four or five million to get it all done. The boat is quite big......" Lin Xinhai shrugged.

"Our boat is also good, luxuriously decorated." Chen Yuan smiled and said, "Besides, we have a frozen ship, and it's useless to have such a big ship."

Lin Xinhai nodded: "11 million, 45 meters, you can know what the internal configuration is like when you think about it." It was a very old longline, not a professional tuna longline." Lin Xinhai said: "The loan from the bank has been approved, and the nanny will be able to drive back tomorrow."

"Why don't you go to the shipyard first?" Luo Laosi asked.

"Hmm...... I have to go to the repair shop first."

Wang Peng's repair shop is a small factory, and there is no problem in changing the offshore fishing boats. However, if you want to change distant-water fishing vessels, you do not have the qualifications to do so.

Distant-water fishing vessels, main engine power, refrigeration tanks, marine equipment, etc., these are all to be registered.

Before going to sea, people from the Maritime Administration will also come on board to inspect the ship.

Distant-water fishing vessels need to be reported for major repairs or major changes.

Of course, it doesn't really matter if you don't report it. The inspection of fishing boats at sea is not particularly strict.

"It's useless for me to follow, and I don't have a captain's card." Chen Yuan said.

"A 59-meter boat, it's too big." Luo Laosi said, "Where did the boat come back and park?"

"Stop over there." Lin Xinhai looked at Luo Laosi: "Then you and I will go to Fujian and drive the ship back."

"Okay." Luo Laosi nodded and said with a smile: "As soon as the big ship sounds, the gold is ten thousand taels...... Get rich."
