Abstract (Croatian)

Proračun stabiliteta i plovnosti kod malih plovila značajno je drugačiji nego li kod velikih brodova trgovačke mornarice. Zbog manje duljine, značajno nižeg nadvođa i mnogih otvora u samome trupu, manji brodovi izloženiji su utjecajima velikih valova, jakog vjetra i jačih stanja mora. Posljedično, brodski registri mala plovila, s obzirom na njihova konstrukcijska obilježja (ovisno o duljini i namjeni broda te primarnom načinu pogona), kategoriziraju u četiri skupine odnosno zone plovidbe: A (Ocean), B (Offshore), C (Inshore) i D (Sheltered). Većina modernih softverskih paketa u sebi ima ugrađena spomenuta pravila. Međutim, već u samoj preliminarnoj fazi osnivanja projekta, poželjno je imati alat koji će projektantu omogućiti brzu kontrolu pojedinih projektnih ideja. U ovome radu nastojao sam navedena pravila sistematično i što jednostavnije iskodirati u svima dostupnom obliku - obliku tabličnog kalkulatora. Na taj način korisniku je omogućen uvid u čitav postupak, a sam ispis dobivenih rezultata pregledan je i fleksibilian s obzirom na zahtjeve korisnika.

Abstract

Stability and buoyancy assessment of small craft significantly differs from large merchant ship assessment. Because of smaller dimensions, significantly smaller freeboard and many hull openings, small boats are more exposed to waves, strong wind and heavy seas effects. Consiquently, according to their dimension, construction properties and prime propulsion, small boats are devided in four categories by the ISO Rules, as follows: A (Ocean), B (Offshore), C (Inshore) and D (Sheltered). Although most of modern software tools already have the Rules implemented by default, sometimes it is very useful, particularly in preliminary aproach, to have a tool that will help designer to evaluate new project ideas rapidly. In this thesis my goal was to sistematicaly and simply transform written rules into program form available to everyone – table calculator form. Thus calculator user is supplied with whole calculation procedure and also the print of acomplished results is descriptive and flexible according to user demands.
