Bow thruster system is a auxiliary aircraft for manouvering the ship when it
lean or will leave the dock, namely by utilizing the propeller rotation which
provides axial force/ transverse force on the bow of the ship.
The formulation of the problem of this research is what factors cause
disturbances to the bow thruster, what impacts are caused, and what efforts are
made to overcome the existing problems. The formulation is to be more selective,
tiered and in accordance with the meaning, the writer uses a qualitative descriptive
analysis method in which the researcher obtains the main data from interviews
and observations. And the author also uses the SHEL method, namely software,
hardware, environment, liveware.
Based on the results of this study it was concluded that the cause of the bow
thruster not working was the corrosion of the support pipe which caused the cable
to peel off, and the control system of the bow thruster auxiliary aircraft did not
work properly. The abnormal operation of the bow thruster has an impact on the
disruption of the ship’s manouvering process, efforts are made to avoid
operational problems with the bow thruster by replacing components that are
damaged/ not functioning properly with new components.
