What it is
A system placing the hull frames longitudinally rather than transversely, with widely spaced reinforcement. It resisted hull bending better over a great length and saved steel weight.
The first ship built to this system was the oil tanker Paul Paix (1908).
What it led to
- longer and cheaper tankers and bulk carriers
- the standard of 20th-century tank ships
- steel savings in the hull
