Classification of Ships

This document provides an overview of the various types of ships used in the maritime industry, categorized by their primary function.


1. Cargo Ships

- Container Ships

Carry standardized shipping containers. Ideal for transporting manufactured goods.

- Bulk Carriers

- Tankers

Carry liquid cargo such as oil, chemicals, and liquefied natural gas (LNG).

- LNG Carriers

Specifically designed to transport liquefied natural gas.

- General Cargo Ships

Versatile ships that carry various goods, often in smaller quantities compared to bulk carriers or container ships.

- Heavy Lift Ships

Designed to carry large, heavy cargo that can't be disassembled, like industrial machinery or offshore structures.

- Reefer Ships

Specialized for transporting perishable goods that require refrigeration, like fruits, vegetables, meat, and dairy.

- Ro-Ro Ships (Roll-on/Roll-off)

Designed to carry wheeled cargo, such as cars, trucks, and trailers.
