About this book:

*Propulsion Systems and Marine Powertrains* provides a comprehensive technical guide to the selection, design, and integration of modern ship machinery. Moving beyond basic engine mechanics, the book explores the complex relationship between hull hydrodynamics, propulsor efficiency, and power distribution. It covers the full spectrum of contemporary technologies, from traditional internal combustion engines and gas turbines to cutting-edge electric architectures, fuel cells, and hybrid topologies. Detailed chapters delve into critical mechanical interfaces—including gearboxes, shaft alignment, and vibration control—while addressing the growing importance of noise management and cavitation mitigation in sensitive marine environments.

Designed for naval architects, marine engineers, and ship designers, this text emphasizes a holistic approach to vessel performance. It integrates rigorous engineering fundamentals with modern digital tools, such as Computational Fluid Dynamics (CFD) and digital twins, to help professionals optimize systems for specific mission profiles. Beyond technical specifications, the book provides actionable frameworks for navigating the shifting regulatory landscape—including IMO and EPA emissions standards—and offers robust financial models for lifecycle costing and risk assessment.

The final section translates theoretical principles into practice through specialized case studies across diverse vessel classes, including tankers, high-speed ferries, offshore support vessels, naval craft, and luxury yachts. By connecting machinery performance with environmental compliance and economic viability, *Propulsion Systems and Marine Powertrains* serves as an essential resource for developing the next generation of efficient, reliable, and sustainable maritime solutions.
