Establishes a method of representing the geometry of ship hull lines in numerical form, to allow the exchange of geometrical data between different systems of ship hull definition. The data formats to be used are specified in ISO 7838.
Abstract
Overview
ISO 7461:1984, "Shipbuilding - Shiplines - Numerical representation of elements of the hull geometry", defines a standardized method to represent ship hull lines in numerical form to enable reliable exchange of geometric data between different ship-definition systems. The standard adopts a plane chain curve as the baseline for shiplines; non‑planar lines are represented by their orthogonal projections. Data-format specifics for interchange are specified separately in ISO 7838.
Key topics and technical requirements
- Basis for lines: A plane chain curve is the standardized basis. Lines not lying in a single plane are described by projections on orthogonal planes.
- Interpolating functions: Ship hull lines are defined using a limited set of interpolating functions - straight lines and circular arcs - to ensure consistent geometry interpretation.
- Segment definition: A hull line is composed of (N − 1) segments, each either a straight line or a circular arc. The circular-arc angle is limited (angle
