Chapter 228: When the Big Ship Sounds, Golden Ten Thousand Taels
Chapter 228 The sound of the ship brings thousands of taels of gold
Chen Yuan and his "big fish" are still installing equipment and replacing the main engine. It will probably be the end of the month to finish everything.
The next day, Lin Xinhai was fine and took Zhao Hai and others to see the fishing boats.
Chen Yuan, Zhou Sheng, and Luo Laosi began to test Dabai's fuel consumption.
High-speed cruising, about 44 knots, fuel consumption is about 300 liters per hour. Fuel consumption per nautical mile is about 6.8 liters.
The three-engine economical cruise has a speed of 35 knots and a fuel consumption of about 193 liters per hour. The fuel consumption per nautical mile is about 5.5 liters.
Dual-engine economical cruising, speed 27 knots, fuel consumption about 130 liters per hour. Fuel consumption per nautical mile is about 4.8 liters.
The single engine has an economical range, a speed of 17 knots, and a fuel consumption of 80 liters per hour. The fuel consumption per nautical mile is 4.7 liters.
Single engine seems to be the most fuel-efficient, but the savings are not much. Moreover, the single-engine mode causes greater engine losses.
The best deal is the Twin Engine Economy Cruise.
Anyway, no matter what, Dabai is a fat tiger, and he is very good at eating oil.
Full tank, 8500 liters.
Just keep the dual-engine economical working state and can work continuously for 65 hours.
Big Fish's reserve fuel tank has 23 cubic meters, which is 23,000 liters, and can support Dabai's work for 177 hours.
Dabai is the Yuanxing 55, and Big Fish is the longline fishing boat.
Dabai is responsible for finding fish and is very fast. The fastest speed of a big fish is estimated to be 23-25 knots.
The speed of fishing boats rarely exceeds 20 knots. When the speed exceeds 20 knots, fuel consumption is linear.
Chen Yuan and the others also have a refrigerated ship with a reserve fuel tank of 100 cubic meters + 95 cubic meters.
100 cubic meters of oil are reserved for fishing boats and 95 cubic meters of diesel are reserved.
"Dabai's fuel consumption is really going to kill the old immortal, it's too scary." Luo Laosi looked at the fuel consumption calculated by Chen Yuan, and his head went numb.
Even if it is an economical cruise, during the fishing period, Dabai runs for 5 hours a day, which is 560 kilograms of diesel. If the fish is not found smoothly, it will use 1 ton of diesel a day, which is easy.
And the big fish boat is also an oil tiger.
The upper limit of host power is 2900kw.
1 meter of horsepower (horsepower) = 0.735 kilowatt (kW), which means that Dabai has almost 2100 horsepower.
Marine engines usually refer to kilowatts, and fuel consumption depends on the fuel consumption rate of the engine, that is, how many grams of fuel are consumed per kilowatt per hour.
The general unit is g/kw.h.
Most marine engines within 1000kw have a fuel consumption rate of about 200g/kw.h. If calculated according to this calculation, the fuel consumption per hour of 1000kw power is 1000 times 200, which is about 200 kilograms of fuel consumption.
Of course, fuel consumption depends on actual use.
Different hosts have different fuel consumption rates. The more expensive the host, the lower the fuel consumption rate. There are also large hosts, which also have low fuel consumption rates. Low fuel consumption does not mean less fuel consumption. This depends on the power...
…
For example, the sixth-generation 400,000-ton ultra-large ore ship has a main engine rated power of 32,970 kilowatts and a fuel consumption rate of approximately 105 g/kWh.
The daily fuel consumption of the 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 power limit of Dabai's main unit is 2900kw, which should be said to be the total power limit of 2900kw.
Dabai has a main engine, a backup machine, and an independent generator, with a total power limit of 2900kw.
After all, Dabai's main fuel tank is only 139 cubic meters, which is about 123 tons of fuel.
If you are just driving on the road with a low load, Dabai's daily fuel consumption is estimated to be 2.5 tons.
The original main engine power limit of this ship is only 1000kw, so the 139 cubic meter main fuel tank is completely sufficient.
Now that a lot of upgrades have been made, the 139 cubic meter main fuel tank is a bit unsatisfactory.
In fact, it is enough for Big Fish to have a 1000kw main engine. When replacing the main engine, the most important thing is to consider the motor boat Dabai.
Dabai is an oil tiger, Big Fish also has an oil tiger, and there is also a freezer ship...
Return to Daozhapo and dock at Dabai.
Outside the original ship repair shop, Lin Xinhai was sitting in a shed drinking tea. When he saw Chen Yuan and the others coming back, he came over and asked, "How is the fuel consumption of the economic cruise?"
"What an economical cruise? It's not economical at all. The cheapest one has a fuel consumption of about 4.8 liters per nautical mile." Luo Laosi shouted.
"1 nautical mile, 4.8 liters?" Lin Xinhai also felt a headache.
Yacht oil is different from ship oil.
Yacht oil is much more expensive.
The current domestic oil price is 31.5 yuan per nautical mile.
But it’s not bad, even if I run 300 nautical miles every day, that’s... 9,500 yuan?
Lin Xinhai calculated again and thought of digging a hole.
If you add big fish and nanny to this...
Nanny is the name of the freezer ship. The freezer ship they bought has certain functions of an auxiliary ship. The name 'Nanny' couldn't be more appropriate.
Lin Xinhai doesn't know how much he spends every day, but it's just a lot.
"Have Zhao Hai and the others chosen the fishing boat?" Chen Yuan took out a cigarette and handed one to Lin Xinhai and Luo Laosi.
"I've chosen a pair of YJ50."
Fishing vessel category, J is a tuna longline fishing vessel.
"How old is it?" Chen Yuan asked.
"45 meters, the largest ship among the YJ50, 680 tons." Lin Xinhai said.
"A 45-meter longline costs a lot of money."
"That boat is of average quality and costs 11 million in total."
"11 million." Zhou Sheng took a deep breath and said, "Actually, we should also buy a big boat."
"The ship needs to be sent to the shipyard for repairs. It is estimated that four to five million will be invested to complete it. The ship is quite big..." Lin Xinhai shrugged.
"Our ship is not bad, it is luxurious and well-decorated." Chen Yuan said with a smile: "Besides, we have a refrigerated ship, so there is no use in having such a big ship."
Lin Xinhai nodded: "11 million, 45 meters, you know what the internal configuration is like. It is a very old longline fishing boat, not a professional tuna longline fishing boat." Lin Xinhai said: "Bank
The loan over there has been approved, and the nanny can be driven back tomorrow."
"Why don't you drive to the shipyard first?" Luo Laosi asked.
"Well...we need to go to the repair shop first."
Wang Peng's repair shop is a small one, so it's no problem to modify offshore fishing boats. But if he wants to modify offshore fishing boats, he doesn't have the qualifications to do so.
Ocean fishing vessels, main engine power, freezing chambers, marine equipment, etc., all need to be registered.
People from the Maritime Safety Administration will also come on board to inspect the ship before going out to sea.
If a distant-water fishing vessel undergoes major repairs or major modifications, it must be reported.
Of course, it doesn’t really matter if you don’t report it. Inspection of fishing boats when they go to sea is not particularly strict.
"It's useless for me to follow, and I don't have a captain's certificate." Chen Yuan said.
"A 59-meter boat is too big." Luo Laosi said: "Where can we get the boat and park it?"
"Stop at the Dongjiang River." Lin Xinhai looked at Luo Laosi: "Then you and I will go to Fujian and bring the ship back."
"Okay." Luo Laosi nodded and said with a smile: "As soon as the big ship rings, there will be ten thousand taels of gold... and you will make a fortune."
