What are types of ship used to carry chemicals in bulk as per IBC code ?

In general ships carrying chemicals in bulk are classed into three types:

1. ‘Type 1’ ship is a chemical tanker intended to transport Chapter 17 of the IBC Code products with very severe environmental and safety hazards which require maximum preventive measures to preclude an escape of such cargo.
2. ‘Type 2’ ship is a chemical tanker intended to transport Chapter 17 of the IBC Code products with appreciably severe environmental and safety hazards which require significant preventive measures to preclude an escape of such cargo.
3. ‘Type 3’ ship is a chemical tanker intended to transport Chapter 17 of the IBC Code products with sufficiently severe environmental and safety hazards which require a moderate degree of containment to increase survival capability in a damaged condition.

Note :

• Type 3 ships are similar to product tankers in that they have double hulls but have a greater subdivision requirement.
• Types 1 and 2 ships must have their cargo tanks located at specific distances inboard to reduce the possibility of impact load directly onto the cargo tank.
