Abstract
The paper presents the parametric optimization of a double hull AFRAMAX tanker design, targeting reduced oil-outflow probability and increased cargo carrying capacity. The contradicting objectives of maximizing the cargo volume while at the same time minimum cargo area steel weight and mean oil outflow index are treated as part of a multi-objective decision making problem. A parametric geometrical ship model has been developed in NAPA®, while the structural model was created by POSEIDON®. The integration of the above software packages has been assigned to the modeFRONTIER® optimization software. The developed approach leads to an automated optimization procedure allowing an im proved feedback to the designer for the trade-off between the various design parameters, optimization criteria and decision-maker preferences. Obtained results suggest notable improvements in transport capacity and oil outflow performance of known well established yard designs.
