Which is more advanced, tower construction method or general subsection construction method?

This is a different construction method.

The tower is built by taking the keel of the ship first, then loading things on it bit by bit, and finally building it.

This method is the most traditional shipbuilding method, and it is popular when the early welding process is immature and the machining accuracy is not high, because it can effectively eliminate the deformation between different modules.

But the disadvantage is that the working face is small, it is impossible to start at the same time, and the construction speed is slow.

The total section construction method is equivalent to dividing the ship into several modules.

We can produce different modules in several factories at the same time.

Finally assembled together.

It's faster and takes less time on the slide.
