Construction of a Small-Scale Tugboat

Abstract

Support vessels for other ships emerged to provide specialized assistance in port logistics. Among these support vessels are tugboats. In this logistics, a tugboat that has an ineffective propulsive system will cause poor support, bringing losses to the sector's production chain. The problem addressed in the work aims precisely to present the construction process of tugboats as complex and dynamic, but at the same time allows to achieve very favorable results in terms of teamwork and the use of computer simulation in the process of projecting parts and components. This work presents the process of building a tugboat on a reduced scale, the elements mentioned here are valid for the construction of tugboats at any scale, which reaffirms the importance and topicality of the theme addressed. The procedures for the construction of the 2017 naumodel were described. Hull designed in DELFTship. The construction of the tug was made by cuts in welded 3mm aluminum sheets. The propellers designed using 3 software: NavCad, PropCad and SOLIDWORKS, cast through 3D molds printed on ABS molds. Magnification box designed, using parameters from NavCad results, in Autodesk Inventor, model 1:1.2. Axis and alignment of the motors carried out in order to reduce the maximum losses.Palavras chaves: rebocador, projeto mecânico.
