To provide: an oil tanker crude oil tank corrosion prevention process in which the corrosion of the bottom of oil tanker crude oil tank can be suppressed without changing the material of the tank; and a ship equipped with equipment to perform said corrosion prevention process.SOLUTION: Provided are: an oil tanker crude oil tank corrosion prevention process characterized in taking out the crude oil from a crude oil tank of an oil tanker, followed by injecting a liquid containing an antibacterial agent into the crude oil tank; and a ship equipped with equipment to perform said corrosion prevention process. For the corrosion prevention process, there are: a process in which an antibacterial agent is added to the residual liquid collected at the bottom of the tank and blowing to the tank; and a process in which an inert gas is filled in the tank, followed by spraying a liquid containing an antibacterial agent into the tank.SELECTED DRAWING: None
【課題】タンクの素材を変更することなく、油槽船原油タンク底部の腐食を抑制する油槽船原油タンクの防食方法および当該防食方法を行う装備を備えた船舶を提供する。【解決手段】油槽船の原油タンクから原油を取り出した後に、前記原油タンク内に抗菌剤を含有する液体を注入することを特徴とする油槽船原油タンクの防食方法および当該防食方法を行う装備を備えた船舶である。防食方法には、タンク底部に溜まった残留液体に抗菌剤を添加してタンク内に吹き付ける方法と、タンク内に不活性ガスを充填した後にタンク内に抗菌剤を含有する液体を噴霧する方法とがある。【選択図】なし
