Naval architecture applies fluid mechanics, structural engineering, and stability analysis to hull and structural design, increasingly including battery-hybrid and fully electric propulsion configurations for new-build and retrofit vessels. As a hard skill it requires hydrostatic and stability calculations, compliance with classification-society structural rules (DNV, Lloyd's Register, ABS), and integration of large battery systems into vessel layouts without compromising buoyancy, trim, or structural integrity. Practitioners apply this knowledge when locating battery packs to minimize center-of-gravity shift, preparing stability booklets for battery-powered vessels, and evaluating structural modifications required to carry the mass and volume of heavy marine energy-storage systems.
