Landing ships have the ability to run aground without damage on sea or river shores, but they cannot go ashore.
This problem can be solved by adding the ability to move on the ground to the ship.
The ship could move on the ground in such a way that the hull of the ship is divided into three parts, as shown in the picture above.
Such a ship has a central hull (1) and two side hulls (2), one on each side. These three hulls are interconnected by two or more strong supporting pipes (3) that pass through the upper part through all three hulls. These support pipes (3) have sliding rings (4) mounted on them, which are eccentrically connected to the support pipes (3).
The sliding rings (4) together with the supporting tubes (3) act as a camshaft during rotation.
When the ship runs aground on the shore, then the ship's engines located in the central hull start turning the supporting pipes (3), and the sliding rings (4) turn with them. In doing so, the side hulls (2) descend towards the ground and the central hull (1) rises up and moves forward. By further turning the support tubes (3), the central hull (1) descends towards the ground, and when it touches the ground, the side hulls (2) begin to rise up and move forward. In this way, the entire ship moves forward. Thanks to the large surface that touches the bottom, this type of boat can move on shallow shoals, on swampy ground, on muddy ground, and even on flat dry ground. In this way, cargo or people can be transported on the ground with the ship for shorter land distances, until it reaches the nearby water surface, or the place where the cargo needs to be unloaded. With this type of ship, large loads could be loaded onto the ship outside the port, and unloaded outside the port. And soldiers could disembark after the ship crossed a river or marsh.
