Abstract

U ovom radu proveden je postupak projektiranja glavnog rebra tankera za prijevoz kemikalija,
te su analizirani utjecaji razmaka okvirnih rebara i razmaka uzdužnjaka na masu konstrukcije
trupa.
Na temelju referentnog modela predloženo je i izrađeno devet varijanti različitog razmaka
okvirnih rebara i uzdužnjaka. Prema uzdužnjacima pozicionirani su također uzdužni nosači
dvodna i dvoboka. Kod svih varijanti zadovoljeni su svi uvjeti lokalne i globalne čvrstoće s
obzirom na propisane kriterije klasifikacijskog društva. Dimenzioniranje uzdužnih
konstrukcijskih elemenata konstrukcije provedeno je programom MARS, klasifikacijskog
društva Bureau Veritas prema pravilima ˝Rules for the Clasiffication of Steel Ships˝. Dimenzije
poprečne konstrukcije preuzete su iz predloška te je provedena studija senzitivnosti masa
poprečnih elemenata ovisno o razmaku okvira.
Na kraju su uspoređene postignute mase konstrukcije svih varijanti te su dane preporuke vezano
za razmak okvira i razmak uzdužnjaka u cilju ostvarenja projekta minimalne mase.

Abstract (english)

Through this papper study structural design of midship section of chemical tanker has been
made, and the influence of longitudinals and web frame spacing on construction mass of
chemichal tanker was analyzed.
Based on reference model, nine models have been made using different combinations of
longitudinals and web frame spacing. Double hull girders and double side girders were
positined according to longitudinal spacing. In every variant all local and global strength criteria
were met regarding classification society criteria. Longitudional construction elements have
been designed using software MARS, provided by classification society Bureau Veritas, in
accordance with Rules for the Classification of Steel Ships.
Dimensions of transverse structure elements were taken from the template, and mass sensitivity
study was made depending on the web frame spacing. At the end, all variants were compared
to structural mass, and recommendations regarding the longitudinals and web frame spacing to
achieve minimum structural mass project were given.
