Abstract (Croatian)

Kroz ovaj rad provedena je analiza utjecaja dvaju projektnih parametara (razmak uzdužnjaka i razmak okvira) na masu konstrukcije tankera s dvobokom s ciljem dobivanja optimalnog razmještaja uzdužno nosivih elemenata konstrukcije. Na temelju referentnog modela, izrađeno je dodatnih 16 varijanti pri čemu su korištene različite kombinacije razmaka okvira i razmaka uzdužnih elemenata. Kako bi se osigurala relevantnost usporedbe različitih varijanti, nužno je bilo dimenzionirati konstrukcijske elemente tako da svi kriteriji čvrstoće budu zadovoljeni. Dimenzioniranje elemenata konstrukcije provedeno je pomoću programa MARS klasifikacijskog društva BV, prema usuglašenim IACS Pravilima (H-CSR BC&OT) koja su stupila na snagu 01. srpnja 2015. godine. Dobiveni rezultati uspoređeni su s obzirom na postignutu masu konstrukcije, moment otpora i moment tromosti glavnog rebra te postignuti granični moment savijanja, na temelju čega su predloženi optimalni parametri konstrukcije. Ključne riječi: konceptualna faza višekriterijskog projektiranja, brodska konstrukcija, projektni parametri, razmak uzdužnjaka, razmak okvira,granični moment savijanja, tanker s dvobokom, harmonizirana IACS CSR Pravila

Abstract

Through this paper study analysis of influence of two design parameters (longitudinals spacing and web frame spacing) on construction mass of double hull oil tanker has been performed. Based on reference model, 16 additional variants have been made using different combinations of web frame spacing and spacing between longitudinals. To assure relevance of comparing the different variations, it was necessary to define the dimensions of construction elements so that all the strength criteria are met. Defining of the construction elements was conducted using software MARS, provided by classification society BV, in accordance to harmonized IACS Rules (H-CSR BC&OT) which came into force on first of July 2015. Obtained results have been compared by construction mass, section modulus, moment of intertia and ultimate bending moment of midship cross section. Based on that comparison, the optimal construction parameters were proposed. Key words: concept design procedure, ship construction, project parameters, spacing between longitudinals, web frame spacing, ultimate bending moment, double hull tanker, harmonized IACS CSR Rules
