abstract = {The methodology and procedures are discussed on designing merchant ships to achieve fully-integrated and optimized hull-propulsion systems by using asymmetric aftbodies. Computational Fluid Dynamics (CFD) has been used to evaluate the powering performance through massive calculations with automatic deformation algorisms for the hull forms and the propeller blades. Comparative model tests of the designs to the optimized symmetric hull forms have been carried out to verify the efficiency gain. More than 6% improvement on the propulsive efficiency of an oil tanker has been measured during the model tests. Dedicated sea-trials show good agreement with the predicted performance from the test results.},

abstract = {This paper discusses a procedure to optimize ship hull forms for minimum required power and best wake field quality, based on CFD computations of the viscous flow. A flexible and effective definition of parametric hull form variations is used, based on interpolation between basis hull forms. All RANS computations were performed for full-scale Reynolds number. An initial optimization has been obtained neglecting the ship’s wave making. Clear Pareto fronts and trends in the solutions are obtained in a systematic variation study for the afterbody of a chemical tanker. In addition we performed a systematic variation using RANS free surface, to study the influence of wave making on the computed trends. As a result, a further decrease in the object functions could be obtained and another hull form appeared to be optimal.},
