Abstract

Unutar diplomskog rada provedena je statička analiza strukture fiksne rešetkaste platforme, i u slučaju operativnih vremenskih uvjeta i u ekstremnim vremenskim uvjetima. U razmatranje su uzeta opterećenja od vlastitih težina, opterećenja procesnog postrojenja, te okolišna opterećenja uključujući opterećenja uzrokovana vjetrom, valovima i morskom strujom. Formirane su kombinacije opterećenja koje uzrokuju najveća moguća naprezanja u elementima strukture. Hidrodinamičke sile morske struje i valova izračunate su korištenjem Morisonove jednadžbe. Analiza je provedena koristeći programski paket SESAM, temeljen na metodi konačnih elemenata, a po pravilima API Recommedned Practice for Planning, Designing and Constructing Fixed Offshore Platforms-Working Stress Design. Struktura je provjerena s obzirom na kriterij izvijanja i granicu tečenja koristeći API kod provjere unutar SESAM-ovg programa Framework.

Abstract (english)

Static analysis of fixed offshore platform's structure in both operational and storm environmental load conditions is considered within this diploma thesis. Dead loads, live loads and environmental loads including wind, current and wave are taken into considoration within analysis, forming load combinations which produce maximum stress levels on structure elements. Hydrodynamic forces including wave and current forces are calculated using Morison equation. Stress analysis was performed using SESAM software based on finite element method, and guided by API Recommedned Practice for Planning, Designing and Constructing Fixed Offshore Platforms-Working Stress Design. Structure capability was checked in regard of stability and yield criteria, by API code checks implemented within SESAM software module Framework.
