Floating docks are platforms or ramps that can be submerged to allow a ship to enter and dock. Floating docks are known as ‘pontoons’ in some regions of the world. A floating dock is connected to the shore with an inclined surface that rests on the dock on rollers. These rollers allow adjustments for the vertical movement of the springs, which are held in place by anchored cables. Floating docks are often seen in small boat marinas. They maintain a fixed vertical relationship with the vessels secured to them, regardless of the elevation of the tide, river or lake. Several of these piers are attached to accommodate a larger ship.
Aluminum floating springs are a commonly acceptable variety, because aluminum is chip-proof, will not rust or rot, and will not warp or crack over time. These products will survive the elements year after year despite the weather. They exhibit amazing flexibility and retain their shape and strength in rough water.
At a sea dock, Floating dock are used to lift a boat out of the water for repairs; These are known as “dry docks”. This also allows the boats to be launched gradually, compared to gravity-assisted launches of the past. Drydocks have concrete, steel, or wooden posts called “locks.” Conforming to the shape of the hull, these posts keep the boat upright when the water is drained from the dry dock.
Tugboats help ships to enter a floating dry dock. There are hydraulic gates, also called valves, that can be opened to allow the chambers to fill with water.
