A CAESES Case Study
MARIC (MARINE DESIGN & RESEARCH INSTITUTE OF CHINA), a leading Chinese maritime research organization and a new user of CAESES, set out to optimize the hull form of a baseline container vessel to reduce resistance at 18 and 27 knots. The challenge was to cut resistance while keeping Lpp, beam and draft fixed and limiting displacement change to +0.5%.
Using CAESES for automated deformation (free‑form deformation and Delta surface) and iterative design exploration, MARIC first applied a partially‑parametric approach and CFD (SHIPFLOW) to reduce wave resistance by 16% at 18 knots and 4% at 27 knots (total resistance down 1.5% and 0.6%). By switching to a fully‑parametric model in CAESES and exploring new stern features they achieved much larger gains—wave resistance reductions of 47% (18 kn) and 35% (27 kn) and total resistance reductions of 5.3% and 4.8%—delivering clear, measurable performance improvements.
