What is the purpose of an oil tanker?

An oil tanker refers to a liquid cargo transport vessel used for carrying bulk petroleum or refined oil. The following is a related introduction about oil tankers: 1. Manhole hatches: Cargo is loaded and unloaded through pipelines using oil pumps, so there are no cargo handling equipment or large cargo hatches on the deck, but manhole hatches are installed. 2. The engine room must be located at the stern: Due to the volatile, flammable, and explosive nature of petroleum, strict fire safety requirements are imposed. The 1978 Protocol of the International Maritime Organization stipulates that newly built oil tankers with a deadweight of over 20,000 tons must have inert gas explosion-proof facilities, and the engine room must be located at the stern. 3. Transverse bulkhead separation: The cargo oil tanks are separated by multiple longitudinal bulkheads and transverse bulkheads to reduce the impact of free liquid surfaces on stability. 4. Large length-to-depth ratio of the hull: The bending moment is large, so a longitudinal framing structure is often used to increase longitudinal strength.
When it comes to the uses of oil tankers, I think their main purpose is to help us transport various liquid cargoes, such as crude oil and refined petroleum products. Life would be impossible without them—the gasoline for cars and the gas for our homes are all transported by oil tankers from production sites. Otherwise, gas stations would run out of fuel, cars wouldn’t be able to move, and prices would skyrocket. Nowadays, there are also specialized tankers for transporting liquefied natural gas (LNG), which is essential for heating in winter. These giant ships work day and night at sea, ensuring stable energy supplies for cities. But it’s important to remember that oil tanker spills can pollute marine ecosystems, so we should try to use energy-efficient products to reduce demand.
As someone who pays attention to the economy, I understand that oil tankers are the lifelines of international trade, crucial for transporting petroleum and chemical products. Crude oil is shipped from Saudi Arabia to China, and refined oil products are sold worldwide, sustaining the entire energy supply chain. Fluctuations in oil prices directly impact commodity prices. A VLCC tanker can transport over 2 million barrels of oil in one trip, offering high efficiency and cost savings. However, piracy or geopolitical conflicts may disrupt shipping routes, causing market panic. Countries rely on oil tankers for petroleum imports; without them, economies would collapse.
I'm interested in engineering. Tankers are specially designed to transport liquids and prevent oil spills. They have multiple isolated compartments to avoid liquid sloshing and capsizing. The valve and pump systems precisely control loading and unloading, enabling the transfer of large quantities of oil at once. Modern materials prevent rust and corrosion, while safety sensors monitor gas concentrations in real time. These improvements reduce the risk of accidents, making maritime transport more reliable.
