Tool For Rapid Generation Of Ship Hull Forms Used For Comparative Performance Analysis Of Various Ship Designs

Summary

This is an abstract from the session entitled "Digital Approaches in Nautical Archaeology", at the 2023 annual meeting of the Society for Historical Archaeology.

The hull of a ship at an archaeological site is almost always incomplete, so the resulting reconstructed hull lines inevitably include some uncertainties. These uncertainties contain the potential to improve the ship's theoretical performance. Hull definition based on analytically defined waterline curves allows easy generation and control of hull form variants. This paper focuses on creating different alternative hull forms in three steps. First, the parent hull form is generated by fitting the analytical model to the reconstructed hull lines. The second step involves defining the allowed hull changes. The third step is a multiobjective optimization of the problem in which the identified uncertainty ranges are used as constraints, while the ship's hydromechanics and navigation characteristics are used as objectives. The calculation of hydromechanical and seakeeping characteristics is based on low-fidelity models that are usually used in the initial stages of general ship design. The research contributes to the results of the project Numerical reconstruction in the archaeology of seafaring (NEREAS, IP-02-2020-3420) funded by the Croatian Science Foundation.
