Corrosion protection of metallic equipment of oil tankers



During the exploitation, corrosion leads to considerable corrosion destruction of the metal equipment of oil tankers.


Corrosion of metal equipment of cargo compartments of oil tankers

Particularly intensive corrosion of metal surfaces of the cargo compartments of oil tankers occurs when carrying crude oil with high sulfur content and light oil products (gasoline, kerosene, diesel fuel). Also, very significant corrosion of metal surfaces of the cargo compartments of oil tankers occurs under the influence of sea water used for washing tanks and ballast. Corrosion of metal surfaces cargo compartments of oil tankers is stimulated by oxygen dissolved in sea water and moist air which is in free area of tanks. Corrosion of metal equipment cargo compartments of oil tankers, as well as ballast tanks takes place at high rate: up to 9.0 mm per year or more.


Corrosive destruction of metal equipment of oil tankers

Corrosive destruction of metal equipment of oil tankers in the cargo and ballast compartments are manifested in the form of large ulcers, cavities that during the time become the through holes in the metal casing of the tanker through which transported crude oil or petroleum products flow out into the sea. Emissions of oil or petroleum products due to corrosive destruction of metal equipment of oil tankers, damage the environment, result in large losses that are associated with the material and financial costs of companies to eliminate the impacts of corrosion destructions of metal equipment of oil tankers.

Protection against corrosion of metallic equipment of oil tankers

The most common way to protect against corrosion of metal equipment in oil tankers in cargo and ballast tanks of oil-loading ships - it is coating the internal surfaces of tanks with various chemically resistant paints. A simple, effective, economical and environmentally beneficial way to protect against corrosion of metal equipment of tankers is a method of protecting metal with hydrocarbon and oil soluble corrosion inhibitors, which are to protect the metal from corrosion of oil tankers form resistant protective film on the metal equipment of oil tankers which is needed to be protected against corrosion.

Corrosion inhibitors for protection of the metal equipment of oil tankers

In the carriage of crude oil and light petrochemicals by oil-loading ships (tankers), as corrosion inhibitors to protect the metal equipment of oil tankers that can be successfully applied to provide protection against corrosion of metal surfaces cargo compartments and ballast tanks, it is necessary to use innovative multifunctional corrosion inhibitors. Multifunctional corrosion inhibitors provide a high degree of protection against corrosion of metallic equipment of oil tankers. Corrosion inhibitors to protect the metal equipment of oil tankers also have high washing and detergent-dispersing properties in relation to various deposits that forming in a metallic equipment of tankers and pipelines. The reagents will prevent the intense accumulation of deposits on metal surfaces of equipment of oil tankers, as well as contribute to their easier and faster removal during washing operations in the cargo and ballast tanks.
