One Thousand Five Hundred and Forty-Two 1 Check and 1 Jump

To know that there are LNG ships, in the field of ordinary civilian ships, we have already caught up with the Southern Dynasties.

But to be honest, what we have been doing has always been relatively low-end products, and the added value is not high.

For an ordinary cargo ship, taking a 50,000-ton ship as an example, the profit margin is not very large, and it can even be described as very meager.

Sometimes many shipping companies can't even earn a little bit of hard money, and even lose money.

Many shipping companies are actually mixing local policy subsidies.

And considering that shipbuilding is a cyclical and long-term work, the most important thing is that during the work period, the exchange rate will often fluctuate.

If sometimes catch up with a bad cyclical change, the exchange rate often fluctuates by a few points, and all the profits of these shipping companies have been swallowed up.

Therefore, if ordinary shipping companies do not have some technology, it is really difficult to increase profits and combat risks.

But having such a dual-fuel engine is another story.

In recent years, the three major shipyards in the Southern Dynasties have not only taken the lead in LNG ships.

In the field of high-end civilian ships, people are also attacking frequently. Our domestic shipbuilding companies can only grab the orders of the low-end and middle-end demand in the world.

While others specialize in undertaking high-end orders, their customers are often relatively well-known large ocean-going shipping companies.

For example, Maersk, Wan Hai, Pacific Shipping, etc., and the most famous one is Hanjin, which just closed down.

If these large shipping companies have another order, the first thing that comes to mind is the shipping companies in the Southern Dynasties.

The reason is simple, because their dual fuel system is very passable.

Those who have not worked in ocean-going shipping companies may not know that the air pollution caused by ships is actually very serious.

Because the earliest ships basically burned heavy oil, the ships at that time had to open up, that is, the smoke was billowing.

After World War II, the level of chemical companies improved, and ships began to burn diesel. Although the pollution problem was alleviated a little, the situation was not optimistic either.

In the early 2000s, the international environmental protection organization once calculated that the annual emission of greenhouse gases from ships is twice that of the aviation industry.

Among them, the annual emissions of nitrogen compounds and sulfides account for 30% and 20% of the total global emissions, respectively!

Therefore, since 2004, many countries and regions around the world have established marine emission control areas (ECAs), which are strict requirements for exhaust emissions from passing ships.

These areas include the entire Baltic Sea, North Sea, North America, North American Caribbean Sea, Gulf of Mexico, Alaska Marine Fish, Tokyo Bay, Hong Kong, Singapore and many other well-known and important waterways, and sea areas have set strict regulations on dissemination of exhaust emissions.

So since that time, many shipbuilding companies in the world have begun to study dual-fuel engines one after another.

Because everyone knows that the use of LNG is absolutely non-polluting and environmentally friendly fuel, but it is not cost-effective to use LNG alone.

After all, the calorific value of LNG is relatively low. To put it bluntly, it is boring to burn, and the power that can provide the ship is not very strong.

Fortunately, the general bulk wheel does not require high speed, as long as it meets 15-20 knots.

The speed requirement of large containerized freighters is only 20-25 knots.

Therefore, as long as it is not a high-speed military vessel or a special vessel, in fact, LNG is sufficient as a fuel to power the vessel.

Especially when entering the seas where exhaust emissions are controlled, as long as you switch to the LNG power system, you can maintain economic cruise.

After all, if all LNG fuel is used, then the current cargo ship's fuel tank can basically meet the voyage of 10,000 nautical miles.

If you add a diesel fuel tank, it can increase the range of 18,000 nautical miles.

And this dual fuel tank configuration is already the limit configuration of the ship's space in addition to the current mainstream freighter carrying capacity.

After all, if you pack too much fuel, you can't guarantee enough cargo.

In fact, many conditions have already been thoroughly studied by shipbuilding companies from all over the world.

In addition, some OEMs have already started layout research in the dual-fuel field.

One of the earliest ones to start is Wärtsilä in Finland.

Many people may have heard of Nokia in Finland, but they do not know that there is another very famous company in this country, that is Wärtsilä.

This company is an uncompromising giant in the field of heavy industry in Europe. It has experienced ups and downs and almost went bankrupt several times, but it has returned to the top of the industry with its tenacious vitality.

Now they do not build ships themselves, but they provide technical solutions to shipbuilding companies all over the world.

Even the dual-fuel engine system of Samsung Heavy Industries in the Southern Dynasties originated from the technical support of Wärtsilä.

And this enterprise and our state-owned enterprise have also cooperated very closely. For example, the two shipbuilding enterprises in Zhenjiang, as well as CSSC, Yuchai, etc. are all partners of this enterprise.

This company has provided a lot of technical support to many domestic shipping companies in terms of marine propellers, auxiliary motors, and medium-speed diesel engines.

Of course, this technical support costs money...

In addition, there is another industry leader, that is, the German Man.

This company, which can be described as a rising star in this field, has been studying dual-fuel engines for a relatively short period of time.

But relying on a solid technical foundation, they soon caught up.

The unique skill of this company is that the electronic control is very powerful.

To know the dual-fuel engine, the most difficult part, aside from the hardware injection system, is the electronic control.

Many ships need to reduce their speed and switch to dual-fuel sharing mode after they are built in the exhaust emission control area.

At this time, it is necessary to control the diesel injection supply with exceptional precision.

It is necessary to ensure that there is not much injection, but it can also ensure that it can provide enough power. After all, the power of the ship may be insufficient when purely burning LNG.

Especially when fully loaded.

Therefore, it is necessary to use dual fuels at the same time, and it also involves the problem of lean combustion, that is, the intake air volume of the combustion chamber must be precisely controlled.

These all place extremely high demands on the electronic control system, and MAN can do it exceptionally well in this regard.

So it quickly opened up in the international market, and received many orders from Spanish and Singaporean shipping companies.

Next is the American Caterpillar.

Their dual-fuel engine has typical American characteristics, that is, the power is extraordinarily powerful.

However, in terms of fuel saving, the performance is very unexpected. It is very different from the gas guzzlers of the previous American engines. Their dual-fuel engines perform very well in fuel saving.

Other shipyards, such as Mitsubishi Heavy Industries, also have very good unique skills in jetting.

Especially in the control of diesel injection, they are the first companies to solve the direct injection of diesel engines, so it is something they can do well.

Next, I have to say that Samsung Heavy Industries in the Southern Dynasties, this company is very ghostly.

Their dual-fuel engine was initially based on the introduction of Wärtsilä's dual-fuel system.

But later, he quietly got on the line with Man, and found Man from Denmark. He spent a lot of money to introduce some corresponding technologies from Man.

Finally, it combines the technologies of Wärtsilä and MAN to develop its own unique dual-fuel engine system.

Not to mention, their dual-fuel engine is really good.

Especially since they are large shipbuilding enterprises themselves, they undertake many orders from home and abroad every year.

So I had a lot of opportunities to experiment on various ships, so I quickly got a very rich accumulation of technology.

And soon became unique in the shipbuilding world.

It is precisely by virtue of its leadership in the field of dual-fuel engines that the three major shipping companies in the Southern Dynasties can firmly hold down our shipping companies in the field of high-end freight ships.

A large part of our domestic shipbuilding enterprises now undertake orders from domestic shipping enterprises at all levels.

Or it is also the order of freight companies in some countries with relatively weak economic strength in Southeast Asia.

For those orders with high economic added value, we basically cannot get them.

There is no other reason, because it is not good in the dual-fuel engine!

Overseas shipping companies also know that the labor in our country H is cheap, the level of shipbuilding is not bad, and the cost of shipbuilding is indeed cheaper than that of the southern country.

But why are you still reluctant to give us an order?

Because our shipping companies do not have the strength to produce dual-fuel engines and cannot install dual-fuel engines on ships, there are many routes that cannot be run.

Especially the very important North American route now, if you can't go to the United States, the most important market in the world, how can you make money?

Moreover, the emission requirements of ships in Singapore waters are also very strict. If your engine emission exceeds the standard, Malacca will not be able to pass.

Even if it can pass, it cannot be docked for correction. Which shipping company dares to use such a low-level ship?

Even our shipbuilding companies can import engine systems from Wärtsilä or MAN and assemble them on our ships.

But this way, the price will naturally go up!

Compared with the three major ship companies in the Southern Dynasties, you have no price advantage. Who would want to buy your ship?

Therefore, although our shipyard can also build ships that meet the environmental protection requirements of international waters, these ships are generally ordered by domestic shipping companies.

Foreign orders are rarely available.

Because you don't have excellent dual-fuel engine technology, you rely on the introduction of Wärtsilä and MAN engines. These two guys' knives are absolutely sharp enough.

When slaughtering people, one is more ruthless than the other.

Just like Wärtsilä, sometimes the system solutions they provide can even account for 60% of the cost of the entire ship.

Damn, how do you let the shipbuilding company live?

After all the hard work, he worked for Wärtsilä, and he couldn't even drop his hard-earned money.

Therefore, in recent years, the once prosperous domestic shipbuilding industry has declined a lot.
