Abstract


Trim optimization is one of the finest strategies to reduce fuel consumption. The trim merely has to be modified for changes in ballast or weight distribution and even both together. To ascertain how bollard pull forces affect trim optimization, which needs to be checked and considered, the study employs a tug hull model in its numerical simulation. However, high angles with tensions significantly change the trim angle, so tug trim needs to be adjusted to obtain the appropriate different trim measurements are used in the forward and stern to get the optimum trim. Nonetheless, the study aims to demonstrate the significant impact of bollard pull angles since bollard effects are noted when a combination of high tension and angle alters the trim and correction required in the selection the appropriate trim optimization.
