Crude oil washing is a method of cleaning the storage tanks of oil tankers using crude oil as a solvent. When crude oil is shipped over long distances, layers of sediment separate from the oil and are deposited on the walls of the storage tank. In the past, this was removed using high-pressure seawater hoses, with the resulting contaminated water generally being pumped into the sea. By cleaning the storage tank walls with a high-pressure spray of crude oil, the sediments dissolve back into There have been more than 1,300 crude oil spills in the US alone. That means oil leaks occur about once every other day. When oil hits the environment, it can pollute water resources, crop lands, and the environment in other ways. That is in addition to the emissions that oil energy creates when it is consumed. Crude oil tankers play an important role in the global oil industry. Tanker ships are the finest means of transport for unrefined crude oil products in mass quantity. As tanker ships carry different grades of fuel oil in the same cargo tanks, it is important that the tanks are always washed before loading fresh cargo. If you work on a tanker ship or about to join one, it is important that you know everything about the crude oil washing operation on tanker ships. Crude oil washing has some disadvantages. The discharge time and port time is increased. Secondly, a slight loss of oil takes place due to vapourization, which however, is negligible. The advantages far outweigh the disadvantages. The monitoring of tank atmosphere before starting COW operations is vital to the safety of the operation. The oxygen content of the tank should be less than 8%, the IG line oxygen content should be less than 5% and the gas in the tank should never be anywhere near During the transportation of crude oil, the most difficult problem encountered is discharging of crude oil. There are some threats, advantages, disadvantages and opportunities during vessel’s crude oil washing operation to discharge its entire crude oil cargo. Under the light of this study, safety measures and auxiliary equipments was Crude oil in its raw state is of little or no value until we take it through the refining processes and transform it into various usable products.
