How thick is an oil tankers hull?

The thickness of an oil tanker's hull typically ranges from 15 to 25 millimeters (0.6 to 1 inch) for most large vessels. However, certain areas that require added strength, such as the bottom and the sides, may have hull plates that are thicker, sometimes reaching up to 30 millimeters (about 1.2 inches). The exact thickness can vary based on the ship's design, age, and the specific requirements of its classification society. It's essential for the hull to be robust to withstand harsh marine environments and ensure the safety of the cargo.
