What is a Type 3 Tanker?

Published in Tanker Vessels 2 mins read

A Type 3 tanker is a chemical tanker designed to transport Chapter 17 products that pose moderate environmental and safety hazards. These tankers require a moderate degree of containment to enhance their survival capability in the event of damage.

In simpler terms, a Type 3 tanker is specifically built to safely carry certain types of chemicals. These chemicals are hazardous enough to need special precautions, but not so dangerous that they require the most stringent containment measures. The design focuses on making the ship more resilient in accidents, helping to prevent leaks and spills.

Key Characteristics of a Type 3 Tanker:

  • Cargo: Transports Chapter 17 products as defined by the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (IBC Code).
  • Hazard Level: Carries chemicals with sufficiently severe environmental and safety hazards that require a moderate degree of containment.
  • Containment: Equipped with features to increase survivability in a damaged condition, minimizing the risk of pollution or harm.
  • Regulation: Subject to specific international regulations and standards to ensure safe operation and cargo handling.

Why is the "Type" designation important?

The "Type" designation (Type 1, Type 2, Type 3) is crucial in the design and operation of chemical tankers. It dictates the level of protection required, which directly influences the ship's construction, equipment, and operational procedures. The categorization is based on the potential hazards of the carried substances:

  • Type 1: Designed for the most dangerous chemicals, requiring maximum containment.
  • Type 2: Designed for chemicals with significant hazards, requiring a substantial degree of containment.
  • Type 3: Designed for chemicals with moderate hazards, requiring a moderate degree of containment.

Example Scenario:

Imagine a chemical company needs to transport a specific industrial solvent that is flammable and moderately toxic to aquatic life. A Type 3 tanker would be suitable because it provides sufficient containment to prevent leaks during normal operation and enhance survivability in the event of a collision or grounding, thereby minimizing environmental impact.

In conclusion, a Type 3 tanker is a specialized vessel designed to safely transport chemicals that present a moderate level of environmental and safety risk, featuring enhanced survivability measures to mitigate the consequences of accidents.
