Interpretation of GB/T 17872—2023 Standard

Background of Standard Formulation and Technological Evolution

GB/T 17872—2023 replaces the original GB/T 17872—2009, and mainly updates the ship type scale series for river-sea direct cargo ships. The core contents of this revision include:

• Changes to the scope of the standard (see Chapter 1)
• Addition of definitions of the terms “overall length” and “overall breadth” (see 3.1, 3.2)
• Redefinition of the concept of “river-sea direct cargo ship” (see 3.3)
• Introduction of the ship type numbering system (see Chapter 4)
• Addition of overall technical requirements (see Chapter 5)
• Update and expand the scale series parameters of river-sea direct bulk carriers, container ships and commercial car ro-ro ships

Comparison of main parameters and ship types

Standard implementation recommendations and application cases

Conclusion and Prospect

The release of GB/T 17872-2023 marks a new stage in the standardization of the ship type scale series of river-sea direct cargo ships. By optimizing technical requirements and expanding the ship type spectrum, the standard not only improves the scientific nature of ship design, but also provides strong support for the sustainable development of the shipping industry. In the future, it is recommended to further strengthen the publicity and implementation of the standard and promote the deep integration of ship design and operation in combination with intelligent technology.
