Ship Hull Parameter Optimization Based on OpTides
Overview of Ship General Design
As a core tool for water transportation and operations, the design quality of ships has a direct impact on navigation safety, transportation efficiency, and economic benefits. Therefore, ship general design is a complex and systematic engineering process aimed at ensuring ships meet functional requirements while achieving superior performance and cost-effectiveness.
Key Steps in Ship General Design
Wigley Hull Parametrization
In ship design, the selection of hull parameters has a critical impact on performance. Engineers often use standardized hull models for systematic study and optimization. The Wigley hull, proposed by British naval engineer Wigley, is a classical, idealized model with symmetrical and geometrically simple features.
Key Parameters
The formula defines the hull lines:
y = B/2 (1 - (2x/L)^2) (1 - (z/D)^2)
Adjusting these parameters enables rapid optimization of hull shape and performance under varying operational and environmental conditions.
OpTides-Based Hull Design Optimization
OpTides, developed by TurboTides, is an integrated software for fluid-structure design, simulation, and optimization, specifically designed for ship design and hydrodynamic analysis. It excels in modeling and optimizing Wigley-parameterized hulls with the following advantages:

The optimization process involves:
FFD Technique
Through iterative optimization, OpTides refines the hull shape until design goals are achieved, significantly improving design precision and efficiency.
Conclusion
Optimizing ship design, applying advanced technologies, and implementing scientific management are vital for enhancing vessel performance, advancing water transportation, and ensuring maritime safety. As technology evolves, TurboTides continues to drive innovation in ship design, empowering the industry with cutting-edge solutions.
