Analysis of Risks of Maritime Traffic in the Aquatic Region of Dubrovnik

Pomorski promet u dubrovačkom akvatoriju iz godine u godinu se povećava. Za ljetnih mjeseci dostiže vršno opterećenje i rizik neželjenog događaja (pomorske nezgode) postaje izgledan s mogućim teškim posljedicama. Analiza rizika dubrovačkog akvatorija obuhvaća putničku Luku Dubrovnik i njezino morsko područje i Staru gradsku luku sa sidrištem Lokrumom. U radu su naznačeni identifikacija rizika, učestalost i posljedice pomorskih nezgoda u ovom akvatoriju. Analizirana su dva sudara brodova za kružna putovanja koja su se dogodila na sidrištu Lokrum i s pomoću simulacije napravljen je scenarij manevriranja velikog broda za kružna putovanja u Gruškom zaljevu u otežanim uvjetima. Poradi povećanja sigurnosti plovidbe i manevriranja brodovlja ovim akvatorijem, potrebno je poduzeti više mjera koje se tiču regulacije i kontrole prometa, njegovih rasterećenja u vrsnim opterećenjima, uvođenja sustava nadzora sigurnosti plovidbe i organizacije prihvata brodovlja.Maritime traffic in the aquatic region of Dubrovnik is on the increase each year. During summer months it reaches its peak loads and the risk of marine accidents is imminent incurring possible hard consequences. The analysis of the risk of Dubrovnik aquatic area has comprised the passenger port of Dubrovnik and its marine area and the Old City port with lokrum anchorage. The paper has shown the identification of risks, incidence and the consequences in this aquatic area. Two collisions of cruising vessels which occurred at Lokrum anchorage have been analysed. The scheme of manoeuvering of a large cruising vessel in the Bay of Gruž in adverse conditions has been presented by means of simulation. In order to increase the safety of sailing and manoeuvering of vessels in this aquatic area, various measures of precautions concerning traffic regulation and traffic control must be taken. At the same time the decrease of peak loads should be considered and the introduction of the system of safety control of navigation and the organization of the acceptance of ships
