What is true about composite hoses used in tankers?

Composite hoses are designed specifically for the transfer of a variety of cargoes, particularly in tanker operations. They are constructed from multiple layers of materials that provide strength, flexibility, and resistance to chemical degradation. This makes them lightweight and easy to handle, which is crucial for operational efficiency on board tankers where space and weight considerations are paramount.

These hoses are excellent for transporting a wide range of chemical products due to their ability to resist permeation and corrosion from aggressive substances. Their flexibility allows them to conform to different shapes and configurations, making them suitable for maneuvering in tight spaces commonly found on ships. This combination of characteristics ensures that they perform effectively while maintaining safety standards during the transfer of hazardous or non-hazardous cargoes.

In contrast, the other options do not accurately describe the properties or applications of composite hoses. For instance, claiming they are heavy and hard to handle contradicts their design features aimed at promoting ease of use. Moreover, the assertion that they can only be used for water cargoes limits their versatility, while stating they are non-reusable contradicts industry practices, as many composite hoses are designed for multiple uses under proper maintenance.
