Chapter 5027

"What is the situation of the integrated system of this natural gas power generation ship?" Zhao Xingguo continued to ask.

An Liang half complained and half seriously responded, "In fact, this natural gas power generation ship developed based on a large cargo ship is useless, and it is something that is neither high nor low."

"Because there are many things that need to be modified, including equipment for storing LNG, Uncle Zhao should understand the trouble of storing LNG, right?" An Liang asked.

Zhao Xingguo nodded. The storage of LNG is not a simple matter!

LNG is usually stored in a low-temperature storage tank at minus 161.5 degrees Celsius and a pressure of about 0.1MPa.

0.1Mpa pressure is almost 1 standard atmospheric pressure. This pressure condition is not troublesome, but minus 161.5 degrees Celsius is a big trouble.

The process of transferring LNG from LNG carriers to gas power ships is very complicated. Although LNG has the word "liquefied" in its name, it does not mean that it can flow directly from LNG carriers to gas power ships like liquids.

Once the low temperature environment is lost, LNG cannot remain in a liquefied state and becomes gaseous, and its volume will expand to 600 times!

However, LNG carriers do not have any powerful refrigeration equipment. They rely on advanced structures and materials to complete insulation, thereby ensuring the safety of LNG.

Therefore, it is difficult for LNG carriers to directly transport LNG to gas power ships. Only by building corresponding deep cold equipment on gas power ships can LNG be safely stored.

In addition, it is necessary to install natural gas generators on large cargo ships, and then configure a super-large graphene lithium-ion battery energy storage station to store the power energy produced by the natural gas generators.

This whole set of transformation not only takes a lot of time, but the initial budget for the transformation cost is as much as 10 Xia Guoyuan.

This is just a preliminary budget!

Just like house decoration, the preliminary budget looks good, but it will definitely exceed the budget.

More importantly, it is indeed useless

"The cost of renovating this natural gas power ship is initially determined to be 1 billion Xia Guoyuan. All renovation costs are provided by Dream Future Energy Group, and Yao's Zhiyuan Shipping Company provides a 30,000-ton 8-year-old cargo ship as a renovation platform." An Liang introduced the situation of the natural gas power ship.

"According to the current plan, we will design and install a 10,000-ton LNG liquefied natural gas warehouse on this natural gas power ship, and at the same time design and install a generator group with a power generation capacity of 200.000Kwh, and then design and install a graphene lithium-ion battery energy storage station with a total capacity of 200,000 kWh." An Liang explained the relevant parameters of the natural gas power ship.

An Liang continued to explain the data in depth, "For every ton of LNG liquefied natural gas, according to the ship's power generationThe motor efficiency can generate about 5,000 kWh of electricity, which is relatively low. ”

“Some land-based natural gas power stations with good efficiency can generate 7,000 kWh of electricity with 1 ton of LNG. "An Liang said in comparison.

This situation is naturally limited by the problem of offshore equipment, which leads to relatively low power generation efficiency.

However, even if the power generation efficiency is relatively low, the natural gas power generation ship can store 10,000 tons of LNG at a time. According to the calculation that 1 ton of LNG generates 5,000 kWh of electricity, that is 100,000 kWh of electricity! (To read the novel, go to Feilu Novel Network!)

The battery pack of the second-generation construction guardian robot has been replaced with a 60-kWh version. According to the calculation of 360 minutes of standard operation per charge, a maximum of four standard operations per day, it consumes about 240 kWh of electricity.

Such a calculation is an ideal state, because in actual situations, these construction guardian robots will definitely stop for inspection and maintenance, and may also enter heavy load mode for high-intensity work.

For example, carrying heavy goods, or performing labor that requires greater strength, etc.

However, when calculating on paper, only an approximate data is needed, so An Liang did not consider these actual The actual data deviation problem.

The 50 million kWh of electricity produced by 10,000 tons of LNG can provide at least 200 days of electricity consumption for 1,000 second-generation building guardian robots.

Of course, the operation of natural gas power generation ships and the maintenance of building guardian robots also require a certain amount of electricity.

But in any case, a natural gas power generation ship can ensure that 1,000 second-generation building guardian robots can maintain normal operation for more than 150 days when it is filled with LNG according to the design plan.

Such a design plan fully meets most usage scenarios, including the current project of building a fourth-generation nuclear power plant in the West, which actually only invested 1,000 building guardian robots.

Even if Anliang is planning to build a secret base in Antarctica this time, such a natural gas power generation ship can actually meet the needs.

But why does Anliang still think that this kind of natural gas power generation ship is useless? .
