Design Procedure And Mathematical Models In The Concept Design Of Tankers And Bulk Carriers

摘要

U radu su razvijene projektne procedure i matematički modeli za osnivanje trgovačkih brodova pune forme. Posebna je pozornost posvećena dvjema dominantnim skupinama ovakvih brodova: brodovima za prijevoz rasutih tereta i brodovima za prijevoz tekućih tereta (tankerima). Izložena projektna procedura je zajednička za obje skupine i može se primijeniti u postupku osnivanja broda različitim metodama: od najjednostavnijih metoda priručnim alatima do suvremenih složenih optimizacijskih metoda i postupaka. Prezentirani matematički model osnivanja broda se zasniva na dugogodišnjem projektantovom iskustvu. Iz više od 150 izvedenih projekata i više od 40 izgrađenih novogradnji u Brodogradilištu Brodosplit je selektiran veliki broj podataka o brodovima. Zasnovano na tim podacima su dane preporuke i za projektiranje koje su prikazane slikama i dijagramima. Izložena projektna procedura i matemački modeli su primijenjeni u višeatributnom programu za sintezu projekta razvijenom na Fakultetu strojarstva i brodogradnje u Zagrebu.%Paper presents design procedures and mathematical models applicable in initial design of merchant ships with high block coefficient. Special attention has been paid to two dominant ship's groups: tankers and bulk carriers. Presented design procedure is common for both groups and it can be applied using various application techniques: from the simplest handy methods to the most sophisticated optimization methods and techniques. Presented mathematical model includes optimization of main ship characteristics as well as optimization of commertial effects of newbuildings. Mathematical models are based on designer's long-time work experience. Large number of data has been derived from more than 150 executed designs and more than 40 ships built in Shipyard Brodosplit. Recommendations for execution of design are shown in number of pictures and diagrams. Presented design procedure and mathematical models have been applied in the multiattribute decision support optimization programme developed in Faculty of Mechanical Engineering and Naval Architecture, University of Zagreb.
