Supercargo for Chemical Tanker Grade Change in UAE

A chemical tanker is defined as a tanker which carries liquid cargoes in bulk. There is a wide variety of
cargoes carries by these ships, not only chemical products but also commodities (vegetable oil, fats,
wine) and inorganic substances (sulfuric acids, phosphoric acid, and caustic soda).

About 30% of liquid trading cargoes (chemical and chemical products) are carried by chemical tankers.
Due to the remarkable growth of chemical industry, shipping industry carries more than 50,000 different
chemical substances. Accordingly the demand for more sophisticated and efficient chemical tankers
shall be increased too.
About Cargo Tank Coating
The chemical tanker is a very special type of ship due to the complexity and the particularity of the
cargo. So most of the times, much attention is given to the cargo tanks and to their ability to ensure the
quality and purity of the cargo throughout the voyage.
Cargo tank coating has two main roles, first to create a separation barrier to avoid direct contact
between the mild steel (tank construction) and the corrosive cargo substance. Secondly, it must have
smooth/slippery surface to provide easy tank cleaning operation.
Cargo tank coatings can be categorized into two main groups:
1.Inorganic coatings- zinc silicates and ethyl silicate types.

Generally, the life of this coating is proportional to the thickness of the coat. This coating is one-layer
coating, comprising of inorganic silicates pigmented with high percentage of zinc powder.

2.Organic coatings - epoxy and modified epoxy systems.

This type of coating consists an organic resin system, which form strong chemical bonds between the
resin molecules. Those types of coating have the ability to resist in more strong acids or alkalis than
inorganic coatings. And they tend to absorb significant quantities of cargo and contamination problems
can occurs

Coating Systems and Types

Numerous types of coating have been used for cargo tank service in sea trades. Some of these coating
have stopped to being used. And more reliable and flexible coating has been developed. Typical coating
system can be categorized as Zinc and Epoxy coating

Coatings are required for any cargo tank which constructed from mild steel. Most of BLT Chembulk
Group modern chemical fleet is SUS cargo tank. SUS are good materials for chemical tanks, because of
their ability to create a passive layer on their surface. This passive layer is mainly consisted by chromium
oxide,which is very resistant to corrosive environment.

However, in some environments like strong hot acids, chloride solutions and generally solutions which
contain halogens, the passive film can break down locally and new film formulation can be disrupted.
Generally, SUS is considered to be the ideal material of construction because it's non-corrosive and easy
to clean.
