A dock is a structure on the edge of the sea, river, or lake that is used as a place for ships to moor. Docks also come in several types, each with different functions suited to sailing needs.
In the dock area, ships can embark and disembark passengers or load and unload cargo.
Many people consider a dock to be the same as a port, even though the two have different roles.
Now, to understand what a dock is and its differences from a pier, wharf, and port, read this article until the end.
What Is a Dock?
A dock is a structure in a port area where ships can berth. At the dock, ships carry out activities such as loading and unloading goods, as well as passenger embarkation and disembarkation. That is why the dock serves as a link between the ship and the land.
When a ship is docked, various activities are usually carried out, such as refueling, replenishing clean water supplies, and disposing of ship waste.
The dock serves as the main area where the ship can stop, making it easier to carry out various operational activities.
The dock structure generally consists of a floor, beams, and piles designed to withstand ship collisions and the loads during loading and unloading.
Its size is also designed to accommodate the ship's type and size, ensuring safe arrival and departure.
This also shows the difference between a dock and a port. A dock is a place for ships to moor, whereas a port is a larger area that includes docks and other supporting facilities.
Types of Docks
Docks come in several types, distinguished by their function and the ships they accommodate. Each dock is designed to support specific activities, ranging from loading and unloading goods to passenger ship activities or special ships. Here are some types of docks that need to be known:
1. General Cargo Dock
A general cargo dock serves various shipping needs. In this area, goods are moved from ships to land or from land to ships to make the distribution process more efficient.
An example can be seen at the dock in Gilimanuk Port, which connects the ferry route between Java and Bali. This dock serves both the transfer of goods and passengers using sea transportation.
2. Fishery Dock
A fishery dock is usually used as a place for fishing boats to dock after going to sea. In this area, the fish caught are usually transferred from the boat to land, where they are distributed or sold. Therefore, fishery docks are specifically designed to support fishing activities.
3. Bulk Cargo Dock
A bulk cargo dock is used for loading and unloading bulk goods, which are items shipped in large quantities without packaging. These goods are usually loaded or moved in piles.
Some examples of bulk goods are coal, sand, wheat, fertilizer, or grains. To move them, equipment such as conveyor belts is usually used to perform loading and unloading faster and more efficiently.

4. Marina Dock
A marina dock is a place for boats such as yachts and speedboats to dock or stop by. This dock is usually located in tourist areas or recreational sailing zones.
Besides being a place for boats to stop, a marina dock also supports various water-based activities, such as sea tours and other recreational pursuits.
5. Specialized Dock
A specialized dock is used for loading and unloading certain goods that require special handling. Examples include gas and oil fuel, as well as other types of cargo that cannot be handled at a regular dock.
This dock is usually equipped with special facilities to ensure the safe movement of goods.
6. Container Dock
A container dock is used for loading and unloading goods packaged in containers. The process of moving containers from the ship to land, or vice versa, usually uses equipment such as cranes to make it faster and more efficient.
Function of the Dock
Docks play an important role in supporting trade and tourism activities in Indonesia. Their presence assists ship operations in transporting both goods and passengers.
The functions of docks are also regulated in the Minister of Transportation Regulation Number 50 of 2021. Some of the main functions of docks include:
- A place for ships to stop or anchor when arriving at the port.
- An area for loading and unloading goods from ships to land or vice versa.
- A place where passengers get on and off the ships.
- A point of transfer between sea transportation and land transportation.
- Help maintain the smoothness, security, and order of activities in the port area.

Differences Between Docks, Piers, Wharves, and Ports
Piers, docks, wharves, and ports are terms in maritime transportation that refer to different facilities.
A pier is a structure that extends from the shore out into the sea and is usually supported by pillars. Ships can dock alongside this structure for loading and unloading, and in some places, piers are also used for recreational activities such as fishing or walking.
A dock is a general term for a place where ships dock. Activities such as transferring goods or loading and unloading passengers are usually conducted in this area. Dock types include piers and wharves.
On the other hand, a wharf is a dock built parallel to the shoreline. This structure is typically reinforced because it is used in commercial ports to handle large volumes of cargo.
Meanwhile, a port is a larger area. Within it, various facilities support maritime transportation activities, including docks, storage warehouses, logistics areas, and other services.
