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

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

The dock takes a long time to dig, but it has high safety during construction 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 segmented site, it will groundwater from the segmented 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 at the dock, and then launch from the slideway at the entrance of the dock.
