Oil ships are vessels that transport crude oil, refined petroleum products, and petrochemicals from one port to another. They are specially designed to carry large volumes of fluid cargo safely and efficiently and are equipped with advanced navigation and safety systems. Oil ships are typically large in size and can range from small tankers to very large crude carriers. The design of oil ships has evolved over the years to increase safety and efficiency while reducing environmental impacts. Modern oil ships are also equipped with advanced technologies to monitor and control the loading and offloading of cargo.
