摘要：
Trim optimization is an efficient method for ship energy saving and emission reduction. An optimized trim condition is beneficial for reducing the fuel consumption and operating cost in ship navigation. Based on sailing data of container ships, the resistance and self-propulsion model tests of an ultra large container ship in a certain displacement and speed range were carried out. The ship model tests in four trims under each displacement-speed condition were conducted to study the influence of the trim optimization on re- sistance and thrust efficiency. An optimal trim calculation program was developed based on the'displacement-trim-speed-delivered power'data mapping. The optimal trim and the corresponding forward and aft draft under specific displacement and speed condition were obtained by bilinear interpolation. The program can help guide the ship stowage adjustment conveniently and provide reference for practical engineering application. © 2022, Editorial Board of Journal of Ship Mechanics.
