No full textOvaj rad analizira onečišćenje morskog okoliša koristeći podatke prikupljene putem europskog satelitskog sustava CleanSeaNet (CSN) u razdoblju od 2015. do 2022. godine. CSN omogućuje praćenje izlijevanja nafte i drugih zagađivača u europskim i susjednim morima te pruža ključne informacije za prevenciju i hitne reakcije na ekološke incidente. Analizirani su podaci o broju opažanja, vrstama onečišćenja, njihovoj geografskoj distribuciji i korištenim satelitskim tehnologijama, poput Sentinel-1 i Radarsat-2.
Rezultati pokazuju da najveći udio u onečišćenjima čine mineralna ulja, dok se ostali zagađivači i prirodni fenomeni razlikuju ovisno o godini. Uočene su značajne fluktuacije u broju opažanja, pri čemu je 2020. godina imala najveći broj zabilježenih slučajeva. Također, analiza ukazuje na važnost daljnjeg razvoja satelitskih tehnologija i jačanja međunarodne suradnje u borbi protiv morskog onečišćenja. Ovim istraživanjem potvrđena je ključna uloga satelitskog praćenja u očuvanju morskog okoliša te potreba za stalnim unaprjeđenjem sustava monitoringa.This paper analyzes marine pollution using data collected through the European satellite system CleanSeaNet (CSN) from 2015 to 2022.

Salvage contract
No full textOvaj diplomski rad bavi se ugovorom o spašavanju temeljem kojeg se obavljaju operacije spašavanja imovine na moru. Ugovor je pravni posao koji nastaje iz suglasnog očitovanja volja dviju ili više stranaka čiji je cilj uspostavljanje međusobnih odnosa i uređivanje postanka, prestanka i promjene tih odnosa. U okviru pomorskog prava spašavanje se definira kao svaka neophodna i korisna usluga i pomoć pružena osobama i imovini na moru koji se nađu u opasnosti. Prilikom sklapanja ugovora o spašavanju, zapovjednik broda, brodar ili vlasnik broda u opasnosti obvezuju se spašavatelju isplatiti određenu naknadu – nagradu za spašavanje koja je limitirana vrijednošću spašene imovine. Kako bi se nagrada realizirala uzima se u obzir davno utemeljeno načelo no cure - no pay, što u prijevodu znači da bez uspjeha nema ni nagrade za spašavanje.This thesis deals with the study of the contract on salvage of assets at sea. A contract is a legal transaction that results from the unanimous expression of the will of two or more parties, the goal of which is to establish mutual relations and regulate the origin, termination and change of those relations. Salvage from the aspect of maritime law defines any necessary and useful service and assistance provided to persons and property at sea who find themselves in danger. When entering into a salvage contract, the ship's captain, shipowner or ship owner agrees for a certain fee, which is regulated by the value of the salvaged items, to provide assistance in removing the ship, cargo and persons from danger. In order to realize the compensation, the English principle "no cure - no pay" is taken into account, in translation without success, there is no reward, and in case of unsuccessful removal of the object of the contract from danger, compensation is not obtained
