Container shipowners joint venture
No full textCilj ovog završnog rada je objasniti značaj i ulogu kontejnerskog brodarstva u međunarodnoj pomorskoj industriji. Brodari poslujući izdvojeno nisu mogli odgovoriti na zahtjeve ostalih sudionika u pomorstvu, pa se iz tih razloga rodila ideja o udruživanju i kooperaciji brodara. S protekom vremena kooperacije su se razvile, međutim došlo je do povećanja zahtjeva koji su stavljeni pred brodarske kompanije. U pomorskoj industriji niža cijena prijevoza i što bolja pokrivenost globalnih kontejnerskih servisa dva su osnovna elementa koja prijevoznik mora zadovoljiti kako bi bio profitabilan na tržištu. Udruženja brodara omogućuju brodarima zajedničko korištenje resursa kojima raspolažu.The objective of this undergraduate thesis is to explain the significance and role of container shipping in the international maritime industry. The ship owners, working alone, could not respond to the demands of other maritime participants, and for these reasons, the idea of association and cooperation of shipowners was born. Over time, collaborations have developed, but there has been an increase in the demand placed on shipping companies. In the shipping industry, low pricing and wide service coverage are two important elements that carriers must offer to make their business profitable. Shipping alliances enable carriers to share their resources

Application of artificial intelligence with emphasis on shipping and transport
No full textU ovome radu opisani su povijest i razvoj umjetne inteligencije, kao i sami pojam inteligencije, koje je potrebno razumjeti prije prelaska na pojašnjavanje primjene. U nastavku je pojašnjena primjena u različitim područjima, njene vrste odnosno oblici, tehnologije na kojima se temelji, te je odrađena usporedba prednosti i nedostataka umjetne inteligencije i strojnog učenja. Nakraju je definirana i objašnjena primjena u području pomorstva i prometa.
Umjetna inteligencija je sposobnost nekog uređaja da oponaša ljudske aktivnosti poput zaključivanja, učenja, planiranja i kreativnosti. Ona se svakoga dana sve više primjenjuje u našim životima, te nema sumnje kako će s njenim daljnjim razvojem primjene biti sve veće. Umjetna inteligencija se temelji na umjetnim neuronskim mrežama. Umjetne neuronske mreže imitiraju neuronsku mrežu ljudskog mozga te pomažu u razvijanju umjetne inteligencije pomoću algoritama strojnoga učenja. Strojno učenje omogućuje drugačije učenje odnosno ponašanje od onog koji mu je programirala neka ljudska osoba.
Primjene umjetne inteligencije su ogromne, od zdravstva odnosno medicine pa do proizvodnje, financija i obrazovanja. Rad je naviše fokusiran na primjene umjetne inteligencije unutar pomorskog i prometnog sektora. Neke od glavnih primjena za pomorstvo su planiranje putovanja, autonomni brodovi te planiranje otpreme kontejnera, dok su za promet tj. cestovni promet neke od glavnih primjena u području inteligentnih transportnih sustava poput detektiranja zagušenosti prometa, zaustavljanja nesreća te pametnog parkiranja.This paper describes the history and development of artificial intelligence, as well as the concept of intelligence itself, which must be understood before moving on to clarifying its application. The following explains the application in different areas, its types or forms, technologies on which it is based on, and a comparison of the advantages and disadvantages of artificial intelligence and machine learning is made. Finally, the application in the field of shipping and transport is defined and explained.
Artificial intelligence is the process of simulating the human brain using a computer system. It is applied more and more every day in our lives, and there is no doubt that with its further development, its applications will increase. Artificial intelligence is based on artificial neural networks. Artificial neural networks imitate the neural network of the human brain and help develop artificial intelligence using machine learning algorithms. Machine learning enables different learning or behavior from the one programmed by a human person.
The applications of artificial intelligence are massive, from health and medicine to production, finance and education. This paper is focused on the applications of artificial intelligence within the maritime and transport sectors. Some of the main applications for shipping are travel planning, autonomous ships and container shipping planning, while for transport, more precisely road transport, some of the main applications are in the field of intelligent transport systems such as detecting traffic congestion, stopping accidents and smart parking
Oil pollution clean-up of different types of coasts and maintenance/storage of pollution removal equipment
No full textLjudsko djelovanje od samih početaka ostavlja tragove u okolišu. Iako su ti tragovi
ponekad pozitivni događaju se i situacije u kojima su izrazito negativni. Onečišćenje
morskog okoliša pomoću tvari koje su opasne po život biljnog i životinjskog svijeta, ali
i po ljudsko zdravlje jedno je od negativnih utjecaja. Uljna onečišćenja mogu se
susresti vrlo često i ne predstavljaju samo posljedicu velikih havarija, već mogu
nastati i tijekom svakodnevnog rukovanja brodovima ili platformama. Doticaj okoliša i
živog svijeta s uljnim onečišćenjem može biti poguban. Upravo iz tog razloga
razvijene su različite metode čišćenja uljnog onečišćenja te različita sredstva i
oprema kojom je isto još učinkovitije, a posljedice manje. Osim toga, vrlo je važno
spomenuti i propise pomoću kojih se uvjetuje implementacija i određenih oblika
opreme na brodove te na obalno područje, a čija je primarna svrha prevencija
nastanka onečišćenja te djelovanje u smjeru očuvanja okoliša.Human activity has left traces in the environment since the very beginning. Although
these traces are sometimes positive, there are also situations where they are
extremely negative. Pollution of the marine environment by substances that are
dangerous to the life of plant and animal life, but also to human health, is one of the
negative impacts. Oil pollution can be encountered very often and is not only a
consequence of major accidents, but can also occur during the daily handling of
ships or platforms. The contact of the environment and the living world with oil
pollution can be fatal. It is precisely for this reason that different methods of cleaning
oil pollution have been developed, as well as different means and equipment that
make it even more effective and have less consequences. In addition, it is very
important to mention the regulations that condition the implementation of certain
types of equipment on ships and in the coastal area, and whose primary purpose is
to prevent pollution and act in the direction of environmental protection
