What is the term for cargo tanks that do not contribute to the vessel's structural integrity?

The term for cargo tanks that do not contribute to the vessel's structural integrity is "independent tanks." Independent tanks are designed to store cargo but are not integral to the ship's overall structure. This means that the tanks can be added or removed without affecting the strength of the vessel. They are typically supported by their own framework and do not rely on the surrounding structure for support.

This design allows for greater flexibility in tank capacity and configuration, facilitating the handling of various cargo types. Independent tanks are crucial in ensuring the safe and efficient transport of liquid cargo, particularly in tankers where maintaining the vessel's structural integrity is paramount.

In contrast, integrated tanks are built into the ship's hull and contribute to its structural integrity. Structural tanks serve a dual purpose of holding cargo while also contributing to the ship's overall strength. Double hull tanks include an additional layer of protection against breaches, adding complexity to their design and structure. Understanding these distinctions enhances knowledge of tanker design and cargo management.
