### *Combinator Curves for Ship Propulsion Control*

The combinator curves for the ship propulsion control modes (constant revolution mode and constant pitch mode) are shown in Figure A5. Setting the sea margin as 15%, the corresponding main engine power in different propulsion control and electric generation modes is shown in Figure A6.

**Figure A5.** Combinator curve of different propulsion control modes. (**a**) Constant revolution mode, and (**b**) constant pitch mode.
