TS 8407

TS 8407 is a terminology standard for shipbuilding software applications concerned with principal ship dimensions. It brings together the terms and definitions used for the main dimensional quantities of a hull and for the non-dimensional coefficients derived from them, supporting consistent use of ship-form and hydrostatic data in computer-based systems.

Principal dimensions and derived coefficients

In ship engineering, principal dimensions are the fundamental geometric measures of a hull, such as length, breadth and depth. In computer programs, these values serve as core inputs for design calculations, hydrostatic assessment, performance studies and data exchange. The focus of this standard is the terminology and definition of those quantities, together with the dimensionless coefficients calculated from them. That helps prevent the same concept from being interpreted differently across software tools and technical databases.

Technical context for computer applications

In general technical practice, ship-related software processes not only raw dimensions but also derived hydrostatic quantities such as draft, displacement and form coefficients. Dimensionless coefficients are especially useful because they allow hull forms of different sizes to be compared on a common basis. Clear terminology therefore matters to design teams, software developers and technical data managers. TS 8407 serves as a vocabulary reference for this computer-oriented domain of ship dimensions and hull description.
