What do tankships exclusively carry?

Tankships are specialized vessels specifically designed to transport liquid cargoes in bulk. This includes a wide variety of liquids such as chemicals, oil, and other liquid materials that need to be carried in large quantities. Their construction features multiple tanks that can be filled with different types of liquids, allowing for efficient and safe transportation.

The focus on bulk liquids is vital for the maritime industry, as it supports the demand for transporting essential raw materials across oceans and waterways. The vessel's design and operational capabilities are tailored to handle the unique challenges that come with carrying liquids, such as ensuring stability, preventing spills, and managing cargo temperature where required.

Other options, such as solid products or personal items, do not align with the primary function and design of tankships, as these vessels are not suited for such cargo types. Similarly, passenger cargo does not fit within the operational parameters of tankships, which are not designed for carrying people or their belongings. Therefore, the correct answer highlights the exclusive nature of tankships in transporting liquid products in bulk.
