Environmental issues and rising fuel prices necessitate better energy efficiency in all sectors. Shipping industry is a stakeholder environmental issues. responsible for approximately 3% of global CO₂ emissions, 14-15% NO(X) 16% SO(X) emissions. Ship trim optimization has gained enormous momentum recent years being an effective operational measure to reduce analysis traditionally been done through tow-tank testing specific hullform. Computational techniques are increasingly popular ship...
