Stability Analysis of USV in Rough Sea Conditions

Project Overview :

Conducted stability and performance analysis for an Unmanned Surface Vehicle (USV) operating in rough sea conditions (Beaufort Scale 2) for a marine company in Singapore.

Key Contributions :

• Implemented overset mesh techniques for accurate wave-vessel interaction modeling

• Employed 6 Degrees of Freedom (6 DOF) analysis to capture complete vessel dynamics

• Simulated wave-current interactions under specified sea state conditions

• Analyzed stability metrics including roll, pitch, and heave responses

Outcome :

• Characterized USV dynamic behavior in specified sea conditions

• Generated quantitative stability performance data

• Provided validated simulation results for engineering evaluation

Tools : CRADLE CFD (scFLOW)
