Heavy forge presses could shape standardised ship structure

Which parts of a warship could be made with heavy forge presses?

Plating, frames, and structural shapes are plausible, especially for standardised ships.

Plating, structural framing, and shaped pieces are plausible candidates for very heavy forge presses. The technique becomes more useful when ships are standardised. Repeated parts can justify the tooling and turn a powerful press into part of series construction rather than a one-off experiment.
