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. Megane Marine
