Abstract (Croatian)

FPSO brod usidren je na velikim dubinama te služi za crpljenje, rafiniranje, skladištenje i prekrcavanje nafte i plina. U ovom radu proveden je proračun matematičkog modela sidrene linije. Prvo je bilo potrebno proračunati dinamički odziv pučinskog plutajućeg proizvodnog objekta (eng. Floating Production Storage and Off-loading). Proračunat je odziv broda na pravilnim valovima za definirano stanja mora i to za različite gazove. Proračun je proveden u programskom paketu HydroSTAR (Bureau Veritas). Osim odziva broda na valovima proračunate su i sile dodatnog otpora. Amplitude odziva broda prikazane su pomoću prijenosnih funkcija. Nakon toga se pristupilo proračunu matematičkog modela sidrene linije preko dobivenih komponenata otpora i karakteristika sidrenih linija. Na samom kraju prikazani su dobiveni rezultati pomorstvenosti, pomaka platforme te geometrijske značajke sidrenog sustava.

Abstract

FPSO ship is anchored to great depths and is used for extraction, refinement process, storage and offloading oil and natural gas. This thesis deals with matematical model of mooring line. Firstly, dynamical response of FPSO was calculated. Structural response was calculated for linear waves, waves for defined sea conditions and all of that for different draughts. Calculation was done in Hydrostar (BV) programme package. Added resistance forces were calculated in addition to structural response. Structural response amplitudes were shown with transfer functions. Afterwards, the calculation of the mooring line mathematical model have begun with processed resistance components and the mooring line characteristics. Finally, seakeeping results, platform movement and mooring line characteristics were shown.
