Abstract

Suhi dokovi su objekti u kojima se vrši remont ili gradnja broda. Za izgradnju ovog kapitalnog hidrotehničkog objekta potrebno je izvršiti analizu tla, ispitati utjecaj podzemnih voda te izraditi projektnu i izvedbenu dokumentaciju. Zastupljena su tri različita tipa suhog doka. Proces izgradnje odvija se na obalnom terenu ili na morskom dnu. Tijekom izgradnje koriste se mnogi elementi koji služe za ojačanje strukture, a materijal od kojeg se grade suhi dokovi armirani je beton. Tlocrt suhih dokova je pravokutnog, a poprečni presjek trapeznog ili pravokutnog oblika. Strukturu doka čine pod (kao najvažniji strukturni element), bočni zidovi, čeoni zid i vrata doka. Dno se u uzdužnom smjeru gradi sa blagim nagibom prema vratima kako bi se omogućilo lakše istjecanje vode tijekom isušivanja doka. Kako bi bili operativni, moraju imati uređaje koji služe za naplavljivanje i isušivanje, instaliran kompletan energetski sustav te sustav gradnje i opremanja. Sustav za naplavljivanje i isušivanje sastoji se od pumpne stanice, pumpi koje se koriste za različite svrhe, usisnih i odvodnih kanala te ventila. Vrata suhog doka razlikuju se dizajnom, konfiguracijom i načinom rada. Na odabir vrata koja su prikladna za određeni tip suhog doka utječu mnogi faktori. Dizalično-transportna oprema važan je dio opreme brodogradilišta zbog izgradnje brodova. Upotrebom dizalica koje imaju veći kapacitet i doseg, omogućuje se brža i efikasnija izgradnja. U ovom radu napravljen je pregled građevno-remontnih mjesta brodogradilišta s posebnim naglaskom na suhe dokove. Prikazan je cjelokupni proces osnivanja, izgradnje i opremanja suhog doka te pojednostavljena strukturna analiza betonsko-masivnog doka opterećenog tankerom za prijevoz kemikalija u izgradnji.

Abstract (english)

Graving drydocks are objects that are used for repair or construction of ships. In order to construct this kind of capital hydrotechnical facility it is necessary to perform soil analysis, to examine the impact of groundwater and make elaborate project and construction documentation. Graving drydocks are usually classified into three different types. Actual building process takes place in the coastal ground or on the seabed. During the construction many elements are used for structural reinforcement, and the material from which drydocks are made is reinforced concrete. The plan view is rectangular, and the cross section is trapezoidal or rectangular in appearance. The structure of drydocks consists of dock floor, side walls, front wall and door of the dock. The bottom in the longitudinal direction is built with a slight inclination towards the door to allow easier flow of water during the drying out of the dock. To be operational, drydocks are installed with flooding and drainage system, complete energy system and the devices for construction and outfitting of ships (vertical transport system). The system for flooding and drainage consists of a pumping station, the pumps that are used for different purposes, suction and drainage channels and valves. Drydock doors can vary due to different designs, configurations and modes of operation. The selection of the door which is suitable for a certain type of dock is influenced by many factors. Vertical transport equipment (namely cranes) are an important segment in the shipyard for the construction of ships. Using a crane, which has a greater capacity and reach, allows for a faster and more efficient construction. In this thesis an outline of ship repair and shipbuilding facilities is given with emphasis on graving drydocks. The whole process of drydock design, construction and outfitting is detailed along with a simplified structural analysis of heavy graving drydock loaded with chemical tanker being built.
