Types of Chemical tankers at Sea
Chemical tankers are required to transport a wide range of different cargoes, and many tankers are designed to carry a large number of
segregated products simultaneously. The operation of chemical tankers differs from any other bulk liquid transportation operations, in
that on a single voyage a large number of cargoes with different properties, characteristics and inherent hazards may be carried.
Moreover, in port several products may be handled simultaneously at one berth, typically including different operations such as discharge and loading as well as tank cleaning. Even the less sophisticated chemical tankers are more complex to operate than oil tankers.

Transportation of bulk chemicals by sea not only requires specialist ships and equipment, but also specialist crew training, both
theoretical and practical, in order for those involved to understand the characteristics of the various chemicals and be aware of the
potential hazards involved in handling them. A particularly important aspect of this requirement is the provision of a data sheet, or
cargo information form, giving details specific to a substance, to be held on board whenever that substance is carried by the ship .
A modem chemical tanker is primarily designed to carry some of the several hundred hazardous products now covered by the IMO Bulk Chemical Codes. The following general types of chemical carriers have developed since the trade began:
Sophisticated parcel chemical tankers:
Typically up to 40,000 tonnes deadweight with multiple small cargo tanks - up to 54 - each with an individual pump and a dedicated pipeline, to carry small parcels of high grade chemicals. These ships have a significant proportion of the cargo tanks made with stainless steel, allowing maximum flexibility to carry cargoes that need their quality safeguarded.
Product / chemical tankers:
Of similar size to parcel tankers but with fewer cargo tanks, mostly of coated steel rather than stainless, and less sophisticated pump and line arrangements. Such ships carry the less difficult chemicals, and also trade extensively with clean oil products.
Specialised chemical carriers:
Small to medium sized ships, often on dedicated trades and usually carrying a single cargo such as an acid, molten sulphur, molten phosphorus, methanol, fruit juice, palm oil and wine. Cargo tanks are coated or stainless steel according to the trade.

Cuprous alloys for shipbuilding of seagoing chemical tankers
Copper and its alloys corrode in many cargoes and may contaminate them, e g styrene, phenol, vinyl chloride, aniline, ammonia solutions etc. Check your cargo against information . Particularly aggressive are the ammonia compounds; they cause inter -crystalline corrosion of cuprous alloys very rapidly. The object in question disintergrates very soon. ....
Use of magnesium and alluminium alloys as sacrificial anodes
Alloys of magnesium and aluminium should never be used in the cargo tank area, due to their poor corrosion resistance in such environments. .....
Introducing rubber lined tanks for the transport of phosphoric acid, waste acids and hydrochloric acid
In recent years a number of ships have been fitted with rubber lined tanks, for the transport of phosphoric acid, waste acids and hydrochloric acid. .....
Tools for shipboard maintenance
Although grit blasting and the use of mechanically powered tools are not normally considered to fall within the definition of hot work, both these operations should only be permitted under controlled conditions. ......
Sea transport of various liquid chemicals at sea
Chemical tankers primarily transport organic and inorganic chemicals as well as vegetable oils and fats. The total global volume of chemicals is estimated at approximately 60 million metric tonnes per year. In addition, the transportation of vegetable oils, alcohols, molasses and lubricating oils amounts to 40 - 45 million tonnes per year. .....
stainless steel as shipbuilding materials for chemical tankers
Iron, steel Mild steel and high tensile steel is, and will continue to be the most important material in the building of chemical tankers and their cargo tanks.Steel is attacked by only a few products, mainly acids and, of course ballast and washing water. Steel itself contaminates very few products, one of them being high purity caustic soda. .... ....
