Simulation challenges in the marine and offshore engineering domain often involve large-scale flow fields, propulsion efficiency, structural vibration, and underwater noise constraints simultaneously. Compared with land-based equipment, the marine environment amplifies fluid-structure interaction and long-term corrosion-fatigue issues.
Industry Characteristics
- Significant interaction among hull, propeller, rudder system, and sea conditions
- Economics heavily depend on energy consumption and propulsion efficiency
- Both military and civil vessel programs place high importance on noise, stealth, and reliability
Core Analysis Content
- Hull resistance and flow field optimization
- Propeller cavitation, fluctuating pressure, and excitation analysis
- Shafting vibration and propulsion system coupled response
- Underwater radiated noise and habitability comfort assessment
Engineering Approach
It is recommended to first determine resistance and propulsion matching through overall hydrodynamic analysis, then build high-fidelity local models for the propeller and post-rudder flow to identify cavitation and pulsation sources. For high-end projects, structural response and acoustic issues should also be integrated into a unified verification chain.
Expected Outcomes
A mature marine simulation solution should simultaneously support three objectives—energy saving, propulsion stability, and noise control—rather than optimizing a single hydrodynamic metric in isolation.
