Abstract (Croatian)

Cjevovodi predstavljaju efikasan način transporta ugljikovodika. Ovakav tip cjevovoda može biti čitavom svojom duljinom ili samo jednim dijelom instaliran na morsko dno. U ovom diplomskom radu razmatrana je podmorska dionica cjevovoda za transport nafte. Za položen podmorski cjevovod napravljene su analize u programskom paketu LS-DYNA, za dva različita profila morskog dna. Dobivenim rezultatima napravljena je procjena strukturnog integriteta prema pravilima Det Norske Veritasa. Prvi profil predstavlja zatečeno morsko dno na zadanoj ruti, a drugi profil je dobiven optimizacijom. Korekcija profila je napravljena s ciljem smanjenja troškova podmorskih radova. U radu je korišten pojednostavljen trokutasti oblik profila za testiranje navedenog optimizacijskog postupka . Rezultati testiranja prikazani su u Prilogu B.

Abstract

Pipelines represent an efficient way to transport hydrocarbons . This type of pipe can be installed on the seabed all over its length or only partially . This master thesis is about subsea section of the pipeline for oil transport . For laid submarine pipeline analysis was done in the software package LS - DYNA , for two different profile of the seabed . Calculation of the structural integrity was made using rules of Det Norske Veritas . The first profile is taken as existing state of the seabed at the given route , and the second profile is obtained by optimization . The correction profile is done to reduce the cost of the underwater work. In the thesis simplified triangular shape of the profile is used to test mentioned optimization procedure . Testing results are shown in Annex B.
