  This scoping review assesses the current use of simulation-based design
optimization (SBDO) in marine engineering, focusing on identifying research
trends, methodologies, and application areas. Analyzing 277 studies from Scopus
and Web of Science, the review finds that SBDO is predominantly applied to
optimizing marine vessel hulls, including both surface and underwater types,
and extends to key components like bows, sterns, propellers, and fins. It also
covers marine structures and renewable energy systems. A notable trend is the
preference for deterministic single-objective optimization methods, indicating
potential growth areas in multi-objective and stochastic approaches. The review
points out the necessity of integrating more comprehensive multidisciplinary
optimization methods to address the complex challenges in marine environments.
Despite the extensive application of SBDO in marine engineering, there remains
a need for enhancing the methodologies' efficiency and robustness. This review
offers a critical overview of SBDO's role in marine engineering and highlights
opportunities for future research to advance the field.
