20.500.12556/RUL-173330 VPLIV GLOBINE POD KOBILICO LADJE NA NJENE MANEVRSKE LASTNOSTI IMPACT OF UNDERKEEL CLEARANCE ON SHIP MANEUVERING CHARACTERISTICS Magistrska naloga »Vpliv globine pod kobilico ladje na njene manevrske lastnosti« je napisana z namenom eksperimentalnega raziskovanja in predstavitve vpliva globine pod kobilico na manevrske sposobnosti sodobnih ladij trgovske mornarice v globoki (referenčni) in plitki vodi. Magistrska naloga je razdeljena na dve sekciji in več podsekcij. V teoretičnem delu naloge so opisane vrste ladij, uporabljenih na simulatorju, ter tipi njihove propulzije. Pri propulziji ladij je posebna pozornost namenjena standardnemu pogonu z notranjim zgorevanjem ter na azipodnemu in Voith pogonu. Prikazane so tudi karakteristike različnih propelerjev in krmil, pri čemer je poudarek na velikosti krmila. Ladje, obravnavane in testirane na simulatorju, so potniška, kontejnerska in ladja za razsuti tovor. Nato sta teoretično obdelana globina pod kobilico ladje in tipi manevrskih preizkusov. Obrazložen je vpliv plitke vode oziroma pojasnjeno, kaj je UKC (globina pod kobilico) in zakaj je pomemben. Empirični del je osrednji del naloge, kjer so predstavljene izvedene simulacije. Simulacije za vse ladje so analizirane in primerjane za vsak tip preizkusa. Rezultati so prikazani kot primerjava manevrskih sposobnosti ladij pri posameznem UKC za vsak test. Manevrske sposobnosti ladje so odvisne od vrste ladje, velikosti krmila, hitrosti in globine pod kobilico. V praksi se je pokazalo, da na manevrske lastnosti plovil vpliva tudi obraščenost trupa. The master's thesis »Impact of underkeel clearance on a ship maneuvering characteristics« is written with the purpose of experimental study and presentation of the influence of under-keel clearance on the manoeuvring capabilities of modern merchant ships in both deep (reference) and shallow water conditions. The thesis is divided into two main sections and several subsections. In the theoretical part of the thesis, the types of ships used in the simulator and their propulsion systems are described. Particular attention is given to conventional internal combustion propulsion, as well as azipod and Voith propulsion systems. The characteristics of various propellers and rudders are also presented, with specific emphasis on rudder size. The ships analyzed and tested in the simulator include a passenger ship, a container ship, and a bulk carrier. Subsequently, the concepts of under-keel clearance and types of manoeuvring tests are discussed theoretically. The influence of shallow water is explained, along with the definition of under-keel clearance (UKC) and its importance. The empirical section represents the core of the thesis, where the conducted simulations are presented. Simulations were developed for all ship types and analyzed and compared for each type of manoeuvring test. The results are displayed as a comparison of the manoeuvrability of the ships at each UKC for the respective test. A ship’s manoeuvring capabilities depend on the ship type, rudder size, speed, and under-keel clearance. In practice, it has also been shown that hull fouling affects the vessel’s manoeuvrability. manevrske karakteristike manevrski preizkusi plitka voda trgovska mornarica potniška ladja kontejnerska ladja ladja za razsuti tovor globina pod kobilico simulator manoeuvring characteristics manoeuvring tests shallow water merchant navy passenger ship container ship bulk carrier under-keel clearance simulator true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-09-16 08:45:49 2025-09-16 08:45:53 2025-11-07 04:01:24 0000-00-00 00:00:00 2025 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 42063 249554691 15635.pdf 15635.pdf 1 038BA1534F45AF931F69889CD6C7F5E0 37e1acbc414b6090c78c3a3e7370d7d29528cf69f98850f5f1a22d18c32acc7b 9e77a3a8-92c8-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=217670 Fakulteta za pomorstvo in promet 0 0 0
