... near-zero speed was observed by the speed over ground display on the ship s bridge, target RPM (power) was applied to both shafts simultaneously. The objective of the acceleration test was to measure the time or acceleration to reach a certain speed (10 knots for this test) with or without the air...

.... The calculation results show that the ship operates at a speed of 10 knots to 11 knots, which can maintain a relatively high speed and profitable status, but also to achieve a lower level of CO 2 emissions from ships. However, this method of finding the best balance point of ship's speed and fuel consumption...
