The Correlation of The Hull-Forms Parametric to The Ship’s Propulsion of Tugboats with Two Propulsion

Abstract

This paper aims to determinethe correlation of power propulsion to hull-forms parametric of twin-propulsion Tugboats. By using the regression method, an analysis of the technical data of existing tugboat is carried out, where the data is obtained by collecting dataon Tugboats that are registeredand operation as many as 381 tugboats. From the results of the analysiswascarried out, it was found that the relations model power propulsion to hull-forms parametric, thenthe model was validated by testing the existing tugboat to determine how many errors the relations model. Based on the results of the analysis carried out, power propulsion affectsthe hull forms parametric, where the increase in power propulsion will increase the value of the hull forms parametric in this case main dimension of the tugboat (L, B, D and T). The value of power propulsion to main dimension of tugboat has a different effect on each type of tugboat.
