How do you convert crude oil tanker to product tanker?

To convert a crude oil tanker to a product tanker, the vessel must undergo modifications to its cargo handling systems and storage compartments. This includes installing additional segregated tanks to accommodate different refined products, enhancing the pumping and loading systems for compatibility with lighter products, and ensuring compliance with safety and environmental regulations. Additionally, the ship's cargo management and monitoring systems may need upgrades to handle the specific requirements of various petroleum products. Finally, thorough cleaning and decontamination of existing tanks are essential to prevent contamination of new cargo.
