With the help of the all-in-one machine, the adjustment part has been adjusted, on the drawings, there are not many places that can be modified, Yang Yuanzhao also knows that with his fur design ability, if it were not for these power equipment and materials, he would not be able to manufacture such a powerful cargo ship, if a professional designer came over, it may be increased by twenty or thirty percent, it is absolutely no problem, but Yang Yuanzhao is already very satisfied, he is not a professional designer, and it is unlikely that the northwest will find a more professional designer, these things, can be taken out for production, at most, let a designer like Pierre get involved in it, how much can be improved.

In the end, the drawings gathered together, but reduced a lot, all kinds of subsystems, material drawings, of course, removed, this is Yang Yuanzhao's hole card, although there is the possibility of deciphering the material, but there is no initial drawing, the finished product produced in many aspects are covered, plus a series of processes such as processing annealing, ever-changing, these are the experience of later generations, to solve it, not only need to invest huge capital, but also need a relatively long time, if you really understand, It may be that more than ten or twenty years have passed, and when the time comes, Yang Yuanzhao will have enough time to improve the level of materials.

Except for the material drawings, there are basically only a few hundred drawings left for the whole ship, Yang Yuanzhao looked at this X1 drawing with satisfaction that may be used as the main cargo ship production of Jiangnan Shipyard in the future, this is an ordinary bulk ship with a load capacity of more than 10,000 tons, with a full load displacement of 15,700 tons, but the hull itself is only about 3,700 tons, which is at least 1,200 tons lighter than the average 10,000-ton ship, and the load ratio is also increasing, and the overall load capacity has reached 12,000 tons, which is quite good. At present, among the 10,000-ton giant ships scanned by Yang Yuanzhao, it is in a relatively leading position.

Basically, most of the shipbuilding costs are calculated according to tonnage, just like the 3,000-ton order of the two Swire ships won before, the price of one ton is 230 US dollars, with a total displacement of 4,500 tons and a total weight of 1,600 tons, the original price is about 370,000 US dollars.

This 10,000-ton freighter, the weight of 1200 tons reduced, represents the increase in profit margins, although the reduction of these weights can not be measured in the cost per ton, but occupies most of the cost, labor and material costs seem to be the largest expenditure on shipbuilding, of course, when the future sales, can not be reduced according to the reduced price, the original weight of about 5000 tons, reduced to 3700 tons, more outstanding performance, but cheaper.

Weight is just a calculation method for shipbuilding owners, and there are other calculation methods, such as the deadweight calculation method, and some methods based on fixed measurements such as performance, etc., and finally negotiated, but there is no such thing as weight.

Taking the drawings of X1 as an example, there are many places to improve, reducing the weight of 1200 tons, but the performance of the whole ship has not been reduced in the slightest, and the strength and stability of the ship, as well as the stability of the dìng under high sea conditions, have been greatly improved, greatly exceeding the mainstream 10,000-ton freighters of various countries.

The most important thing is that his power is extremely good, because Yang Yuanzhao has improved the performance of the steam engine, this 10,000-ton giant ship, originally carried a double 30,000-horsepower steam engine, but in the gradual modification, Yang Yuanzhao did not notice the power problem, and occasionally an accident, a steam engine that had been used to 6600 horsepower replaced the original 15000 horsepower steam engine.

This is an accident, and even a comprehensive modification has not been made, Yang Yuanzhao is preparing to change it back, but finds that in the score of the total drawing, there is no obvious reduction, but it has been reduced by about 1.2, which is not a matter at all in the current score, but the difference between the 6600-ton steam engine and the 1500-ton steam engine is still huge, is there an excess of power?

Yang Yuanzhao carefully looked through the power of other 10,000-ton freighters, and he was surprised to find that the total number of steam engines of the mainstream 10,000-ton freighters in the world was between 3,000 horsepower and 50 million horsepower.

Power is sometimes not as big as possible, for warships, it is so, under the wartime state of opening the maximum speed, it must be as fast as possible, but for cargo ships, it is completely unnecessary, and it is not to make aircraft carrier reserve ships and rapid replenishment ships, it is completely possible to reduce the horsepower, which is not only conducive to reducing the cost, but also conducive to the reduction of coal consumption.

The idea was completely opened at this moment, Yang Yuanzhao seemed to have discovered a new continent, and immediately set out to change the power system, in fact, among the various subsystems of the cargo ship, the power system is the easiest to modify, and the type of steam engine was adjusted through guò, and the adjustments were made in turn on the 15,000 twin engines, 15,000 single engines, 6600 twin engines and 6600 single engines.

The change in the score is not small, and even the more it falls, the higher the score, and finally, when it is reduced to the limit of 6600 horsepower, it is increased to the highest, 152 points, which is 5 points higher than the previous score, From 15,000 horsepower twin engines, converted to 6,600 horsepower single engines, the space is reduced by more than 80, 3,000 cubic meters of space can be saved, in the layout of the cargo ship, there is a larger space, the weight is also reduced by about 180 tons, the two are added, and the final cargo ship's load capacity is barely increased to about 12,600 tons, an increase of 600 tons.

In terms of scores, the most reduced is the cost, coal consumption and space, even if the previous X1 drawings have reached an unimaginably high score of 147 points, but now the number of 152 points still makes Yang Yuanzhao more satisfied.

In fact, compared with ordinary 10,000-ton cargo ships, about 2 times the power increase, the performance improvement is huge, but it has not reached twice the overall level, the reason is that on the one hand, the increase in power has a direct effect on the speed, Yang Yuanzhao's design is limited, and it is impossible to play several times the effect, after careful adjustment, the economic speed, or control zhì in about 10-12 knots, and other 10,000-ton cargo ships are not much different, that is, about 1-2 knots, but the coal consumption, but much better, Because Yang Yuanzhao's steam engine not only adopts the layout of later generations, the efficiency is higher, but also uses a heat recovery device, a special heat recovery device, which can recover almost 89 of the heat, and under repeated recycling, even if the total amount of the power system is much higher than that of other cargo ships, at the same economic speed, or even one or two knots higher, it reduces coal consumption by at least 35 compared with other cargo ships.

On the drawings, the highest score is coal consumption, breaking 100 scores, so that Yang Yuanzhao likes it very much, it can be said unceremoniously, this will become a prominent advantage of Jiangnan Shipyard, in a special time, speed and load capacity will become an important measurement factor, but common sense, transportation consumption is the key, others transport 10,000 tons of goods, the same speed and distance, this side can transport 12,000 tons of goods, the final consumption, will be reduced by more than 30, in this case, The reduced cost of transportation allows the vessel to have considerable competitiveness.

Cargo ship, the main task is to do business, more economical cargo ship, is the most rigid index, not to mention the increase in carrying capacity, in this sense, the benefit of the ship has increased by at least 40 or more, do not underestimate this number, at the critical moment of maritime transportation, the cost will be reduced by about a quarter of the Cheng dù, for a large fleet, more than 100,000, or even 1 million tons of carrying capacity, not to mention about a quarter of the cost, even if it is a reduction of 1,2, For a large-scale shipping company, the number that can be reduced every year may be millions, or even tens of millions of dollars, and this reduction is the value of more than a dozen 10,000-ton giant ships.

For some small merchants, they may not be able to afford such an expensive ship, because the price of such a ship must be above that of an ordinary ship, a 12,000-ton ship is certainly much more expensive than a 10,000-ton ship, not to mention excellent performance, reduced consumption, even if one-tenth of the reduction in consumption is added to the total price, this ship is at least 30 more expensive than the price of ordinary ships.

For some large shipping companies with deep pockets, especially those with strong strength of 500,000 tons, or even millions of tons and millions of tons, it is inevitable to pay a high price for the reduction of overall operating costs and the improvement of operational efficiency.

X1 is just a temporary naming, this ship may be the main cargo ship in the future, it may be named a good name, but these are not what Yang Yuanzhao needs to do, he only needs to take out the drawings at the right time, and the rest naturally has the law of naming.

Yang Yuanzhao stretched his waist, his consciousness came out of the all-in-one machine, he was too focused just now, he came back from four or five o'clock in the afternoon, and now it was starry, look at the pocket watch, it was already about 2 o'clock in the evening, and unconsciously, it was about 10 hours passed, more than 10 hours to get a suitable drawing, and including a complete research direction, this is a great news for Yang Yuanzhao, even, he should have been sleeping, because of this stimulation there was no sleepiness at all, he washed his face, After taking a sip of water, I re-entered the all-in-one machine.
