How does an oil tanker float?

An oil tanker floats due to the principle of buoyancy, which states that an object will float if it displaces a volume of water equal to its weight. The design of the tanker includes a hull that is shaped to displace a significant amount of water, creating an upward buoyant force that counteracts its weight. Additionally, the tanker is built with a lightweight structure and is often partially filled with air, which helps keep it above water. As long as the weight of the water displaced is greater than or equal to the weight of the tanker, it will remain afloat.
