Abstract

ABSTRACT Satria Aji Pangestu, (2023) NIT. 551811236921.T, “Analysis of the malfunction of the bow thruster during manouver on ship MV. Pulau Hoki”, program Diploma IV, Technical, Merchant Marine Polytechnic of Semarang, Supervisor I : Tonny Santiko,S.ST.,MSi.,M.mar.E and Supervisor II : Kresno Yuntoro,S.ST,M.M. 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.
