What are the advantages of the carrier slipway? What are the advantages and disadvantages compared with the dock?

It is relatively simple and convenient to build a berth, which is suitable for building small ships (but small ships are not suitable for the current international freight trend), while building large ships is even more dangerous. There are two slides under the boat. When launching, it slides into the sea through the slideway (with rollers on it), but it needs to be pulled by cable to avoid slipping to the other side when launching. After launching, a tugboat will tow the boat to the shore, and at this time the boat has no power.

It takes a long time to excavate the dock, but it has high safety in the construction process and is suitable for building large ships. When launching, fill the dock with water to float the boat, and then open the door near the sea.

The slipway is that after the ship completes the main assembly in the subsection site, it will drain the groundwater from the subsection site through the slipway and slipway, and then move from the water to the nearby outfitting dock to complete the remaining processes. The ship can complete all the assembly processes in the dock, and then get into and out of the slipway at the dock gate.
