a port is the place where a ship unloads and loads goods.
A ship can be 'on' a berth, which means is is moored (tied up) alongside a specific place called a berth in the dock. Or a berth is also used to describe a place for a crew member on board ship.
A ship yard
As cargo is being unloaded, the weight of the ship decreases. This reduction in weight causes the ship to displace less water, resulting in a buoyant force that gradually lifts the ship higher in the water. This process continues until the ship reaches a new equilibrium where its weight is balanced by the buoyant force.

It is dangerous for a ship to be too lightly loaded because then it floats with less volume inside water. As a result,its centre of gravity is higher and it may get blown over on its side by strong winds.Therefore, an unloaded ship is filled with sand or stones,called ballast,at its bottom.This lowers its centre of gravity so that the equilibrium of ship becomes more stable.
