Abstract (Croatian)

Razvojem industrije jaružanja zadnjih nekoliko godina razvili su se složeni i sofisticirani brodovi – jaružala. Zbog svojih specifičnosti, ovi brodovi zahtijevaju poseban pristup osnivanju, projektiranju konstrukcije te kasnije i pri samoj eksploataciji. Cilj ovog rada je opisati strukturnu analizu usisnog jaružala sa skladištem kapaciteta 14000 m3. Proračunom su provjerena naprezanja i deformacije u primarnim konstrukcijskim elementima te naprezanja u uglovima velikih otvora. Motiv provođenja analize je želja za racionalnom raspodjelom materijala i smanjenjem težine samog broda. Uspjeh strukturne analize i ušteda na težini postignuti su suvremenim pristupom projektiranju.

Abstract

In recent years dredging industry has developed itself significantly, consequently developing sophisticated and powerful ships known as dredgers. The vessels are extremely specialized and require special attention for design, construction and operation. The purpose of this paper is to present the structural analysis of 14 000 m3 Trailing Suction Hopper Dredger. The calculations have been performed to analyze the stress and buckling behavior in the primary structure within the hopper region and to assess the stress concentration in way of the rounded corners of large openings. The aim was to achieve optimized structural scantlings especially in way of primary structure and large openings. Reduction of structural weight has been achieved due to the rational structural design procedure.
