EFFECT OF SPACING AND FORM OF SKEG ON THE POWERING PERFORMANCE OF TWIN-SKEG SHIPS

Xiaomei Xu, Wei Jiang

Open publisher page 0 citations

Abstract

This paper deals with the resistance and self-propulsion tests on four models of a twin-skeg passenger ship. The effects of skeg spacing, skeg inclination and hull form are investigated. According to the authors, the model tests demonstrate the superiority of inward-turning propellers in powering performance. An induced pre-swirl to the propeller was confirmed by wake survey. The influence of hull form is small when the skeg spacing is equal to half the breadth of the ship and the skeg inclination is zero.
