Influence of main dimension ratio of ROPAX on ship resistance performance

  Objectives  This paper investigates the main dimensions of ROPAX ship in the aspect of energy saving and resistance reduction.

  Methods  By using ship model tests and numerical simulations, the effects of changes in the main dimension ratio of a ROPAX ship on its resistance performance are studied.

  Results  The results show that the maximum difference in effective power between different L/B schemes is only 150 W at lower speeds, increasing to 1 300 W at higher speeds, while the maximum difference in effective power between different B/T schemes is only 170 W at lower speeds, increasing to 300 W at higher speeds.

  Conclusions  This paper shows that increasing the L/B value can significantly reduce the model resistance and effective power of the ship, and there is no significant difference in effective power with different B/T values.
