  The design optimization of ship hull form based on hydrodynamics theory and
simulation-based design (SBD) technologies generally considers ship performance
and energy efficiency performance as the design objective, which plays an
important role in smart design and manufacturing of green ship. An optimal
design of sustainable energy system requires multidisciplinary tools to build
ships with the least resistance and energy consumption. Through a systematic
approach, this paper presents the research progress of energy-efficient design
of ship hull forms based on intelligent optimization techniques. We discuss
different methods involved in the optimization procedure, especially the latest
developments of intelligent optimization algorithms and surrogate models.
Moreover, current development trends and technical challenges of
multidisciplinary design optimization and surrogate-assisted evolutionary
algorithms for ship design are further analyzed. We explore the gaps and
potential future directions, so as to paving the way towards the design of the
next generation of more energy-efficient ship hull form.
