Abstract

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 (english)

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.
