Abstract (Croatian)

Porinuće broda složen je događaj, a pogotovo kada su u pitanju netipični brodovi. Iz tog razloga brodogradilišta obavljaju proračune porinuća kako bi odredili brzine i ubrzanja broda, otplov broda, najveći gaz i drugo. Ti su proračuni pouzdani i praktički sva porinuća izvode se uspješno. U ovom radu prikazana je usporedba različitih metoda za procjenu porinuća broda. Tijekom nedavnog porinuća u brodogradilištu Uljanik na brodu su izvedena mjerenja pomoću preciznog diferencijalnog DGPS uređaja (DGPS), a učinjen je i video zapis. Prikupljeni podaci uspoređeni su s podacima proračuna brodogradilišta i teorijskim proračunom. Uočena odstupanja su analizirana i raspravljena.

Abstract

hip launching is a complex event, particularly when uncommon ship structures are in concern. Due to that, shipyards perform pre-launching calculations to determine ship’s speed, acceleration, traveling distance, maximum draft etc. These calculations are reliable and virtually all of the ship launchings are successful. Due to the same reason, they are rarely verified. An attempt is made here to compare different ship launching evaluation methods. Particular launching event, occurred in Uljanik shipyard, was recorded by high-precision differential GPS (DGPS) measuring device and a video camera. Obtained information were analyzed and compared with shipyard and theory based ship launching calculations. A margin for errors was detected and results discussed.
