The impact of multicultural crews on maritime safety
No full textAktualiziranje teme rada rezultat je suvremenih trendova u pomorstvu koje karakterizira globalizacija pomorskog tržišta rada i formiranje multikulturalnih posada. Multikulturalna posada ima svoje specifičnosti koje iziskuju razvijanje kompetencija vezanih uz uvažavanje i razumijevanje drugih kultura. Nedostatnost razvijene multikulturalne svijesti i multikulturalnog razumijevanja može rezultirati međusobnim nerazumijevanjem članova posada, lošom komunikacijom i posljedično stvaranjem nepovoljnih radnih okolnosti, povećanjem sigurnosnih rizika i u krajnjem slučaju do nesreća i incidenata na brodu. Uz teorijske odrednice kulture te isticanje razlika između zapadne i istočne kulture te utjecaja globalizacije na kulturu pojedinog naroda, utjecaj multikulturalnih posada na pomorsku sigurnost u radu se promatrao kroz različite aspekte, kao što su kulturološki čimbenici, komunikacija, dominantnost muškaraca, izobrazba i sustav upravljanja, motivacija i stavovi prema sigurnosti te organizacijski čimbenici povezani sa pomorskom sigurnosti. U radu se zastupa stajalište da razumijevanje različitih kultura i poboljšanje jezičnih vještina, posebice znanja engleskog jezika za pomorce rezultira povećanjem pomorske sigurnosti.The actualization of the topic of work is the result of modern trends in maritime affairs characterized by the globalization of the maritime labor market and the formation of multicultural crews. The multicultural crew has its own specifics that require the development of competencies related to respect and understanding of other cultures. Lack of developed multicultural awareness and multicultural understanding can result in misunderstandings between crew members, poor communication and consequently the creation of unfavorable working conditions, increased safety risks and ultimately accidents and incidents on board. In addition to theoretical determinants of culture and highlighting the differences between Western and Eastern culture and the impact of globalization on the culture of individual peoples, the impact of multicultural crews on maritime safety at work was observed through various aspects such as cultural factors, communication, male dominance, training and management. motivation and attitudes towards safety and organizational factors related to maritime safety. The paper proves that understanding different cultures and improving language skills, especially English language skills for seafarers results in increased maritime safety

U zadnja dva desetljeća postalo je iznimno važno smanjiti utjecaj prometa na okoliš, a to se moze postići konciznim planiranjem urbanih područja, uzimajući u obzir sve sudionike u prometu, kako pasivne tako i aktivne, imajući na umu krajnji cilj – povećanje kvalitete života uz smanjenje negativnog utjecaja.The purpose of this master thesis is to answer research questions aimed at finding a way to reduce the harmful emissions of discharge gases emitted into the atmosphere every day, while causing long-lasting consequences on health and the environment. In the last two decades it has become extremely important to reduce the impact of traffic on the environment, and this can be achieved by concise planning of urban areas, taking into account all road users, both passive and active, bearing in mind the ultimate goal – to increase the quality of life while reducing the negative impact
The process of creating an electronic device from designing to emc testing
No full textIspitivanje sukladnosti uređaja prema propisima odgovornih tijela za određeno tržište ključan je korak prije plasiranja uređaja krajnjem korisniku. Kako bi se potreba za ponovnim redizajnom i ispitivanjem izbjegla, preporučuje se prilikom svakog dizajniranja novog uređaja pratiti preporuke struke i prije krajnjeg testiranja sukladnosti obaviti testiranje u vlastitom laboratoriju. Osim sukladnosti sa zakonom ispitivanje pred sukladnosti uređaja može pridonijeti i kvaliteti krajnjeg proizvoda. U ovom radu prikazani su postupak dizajniranja pločice, izrade pločice i testiranje vođenih i zračenih smetnji krajnjeg uređaja.Testing the electromagnetic compliance of the device according to the regulations of the competent authorities for a particular market is an important step before marketing the device to the end user. To avoid the need to redesign and test a device, it is recommended that when developing a new device, the recommendations of the professional community be followed and laboratory testing be performed prior to final compliance testing. In addition to regulatory compliance, preliminary product compliance testing can also contribute to the quality of the final product. This paper presents the process of developing the board, manufacturing the board, and testing the conducted and radiated interference of the final device
The ecological impact of marinas on the marine environment
No full textNautički turizam je dio međunarodne turističke djelatnosti koja u svijetu bilježi najveći i najbrži rast. On se sastoji od luka nautičkog turizma u čiju podvrstu spada marina. Marina je posebna vrsta luke nautičkog turizma koja pruža usluge veza, smještaja plovila te ostale dodatne sadržaje i usluge. Jedan od negativnih utjecaja na okoliš je izgradnja marina, lukobrana i dodatnih sadržaja. Problem stvara izgradnja luka nautičkog turizma na krivim mjestima što dovodi do raznih onečišćenja. Uz to javljaju se i onečišćenja mora s brodova. Nafta, ispuštanje balasta, ulje i elementi u tragovima uništavaju organizme i negativno utječu na morsku floru i faunu. Mjere sprječavanja onečišćenja očituju se konvencijama, propisima i standardima. Uz navedeno, prikazuje se i održivi razvoj nautičkog turizma Hrvatske.Nautical tourism is part of the international tourism industry, which is experiencing the largest and fastest growth in the world. It consists of the ports of nautical tourism, of which a subtype is the marina. A marina is a special type of port for nautical tourism that provides moorings, boat accommodations and other additional facilities and services. One of the negative impacts on the environment is the construction of marinas, breakwaters and additional facilities. The problem arises from the construction of marinas for nautical tourism in the wrong places, resulting in various types of pollution. In addition, there is a marine pollution from the ships also. Oil, ballast discharge, oil and trace elements destroy organisms and negatively affect marine flora and fauna. Pollution prevention measures are laid down in conventions, regulations and standards. In addition, the sustainable development of nautical tourism in Croatia is presented
The importance of the port system on the competitiveness of the traffic routes
No full textKao posljedica sve veće globalizacije i porasta stanovništva javlja se sve veća potreba za prijevoznim uslugama. Prijevozne usluge formiraju se prema trenutnom tržištu i trenutnom odnosu ponude i potražnje. Potrebe i zahtjevi za uslugom postaju sve veći dok su mogućnosti pojedinog prometnog pravca ograničene. Luka kao bitna karika u prometu općenito ovisi o stalnim promjenama na tržištu, no da bi osigurala svoj položaj na tržištu i suprotstavila se konkurenciji mora biti u korak s trenutnom potražnjom te svojom ponudom zadovoljiti zahtjeve korisnika. Stoga su potrebna stalna ulaganja u razvoj i unaprjeđenje kako infrastrukture tako i same usluge. Kvalitetnijom uslugom stječe konkurentniji položaj na tržištu, a time doprinosi i konkurentnosti pojedinog prometnog pravca.As a result of increasing globalization and population growth, there is an increasing need for transport services. Transport services are formed according to the current market and the current relationship between supply and demand. The needs and requirements for the service are getting bigger, while the possibilities of a particular traffic route are limited. The port, as an important link in traffic, generally depends on constant changes in the market, but in order to secure it's position on the market and oppose the competition, it must keep up with current demand and satisfy user requirements with it's offer. Therefore, constant investments are needed in the development and improvement of both the infrastructure and the service itself. With a higher quality service, it gains a more competitive position on the market, thereby contributing to the competitiveness of a particular traffic route

No full textGlavna tema ovoga rada je prirodni ukapljeni plin koji se koristi kao gorivo na
brodovima. U radu je objašnjen njegov sastav (fizička i kemijska svojstva), opasnosti i
prednosti plina te način na koji se sve on skladišti. Navode se i načini kako se plin
ukapljuje i prevozi. U prvom dijelu rada vraćamo se malo u prošlost nastanka prvih
brodova koji su prevozili i koristili ukapljeni plin. Također navodi se sastav plina, kako se
on ponaša u prirodi i koje su mu prednosti a koji nedostaci. Objašnjeni su načini rukovanja
plinom te postupci koje treba obaviti prilikom direktnog kontakta ljudskog tijela sa plinom.
U daljnjem tekstu pojašnjeno koji su uređaji potrebni na brodu da bi on mogao ploviti na
plin, neke njihove značajke i alarmi. Razradilo se i mali odlomak o pogonskim uređajima
koji rade na plin. Također se govori i o tankovima u kojima se on skladišti, njihove
karakteristike i oblici. Naposljetku naveden je pravilnik koji objašnjava što je sve potrebno
da bi brod prevozio plin i koristio ga kao gorivo.The main topic of this paper is liquefied natural gas used as ships fuel . The paper
explains its composition (physical and chemical properties), the dangers and advantages of
gas, and the way it is stored. The way which gas is liquefied and transported are also listed.
In the first part of the paper, we are going back into the past of the creation of the first
ships that transported and used liquefied gas. It's also stated the composition of the gas,
how it behave nature and what are its advantages and disadvantages. Also the ways of how
you are handling gas and the procedures when the human body comes into direct contact
with gas are explained. In the following text, it is explained which devices are needed on
ship using gas as fuel, some of their features and alarms. A small section on propulsion
devices that run on gas was also elaborated. It is also discussed about the gas stored tank,
their characteristics and forms. At the end, there is a regulation that explains what is
needed for a ship to transport gas and use it as fuel
The influence of the fuel change-over method on the main engine operation
No full textU ovom radu provedeno je istraživanje o tome kako brzina tj. vremenski interval prebacivanja goriva utječe na specifičnu potrošnju goriva, viskozitet goriva, temperaturu goriva i ostale praćene parametre motora. Svi podaci su prikupljeni analitički i grafički, te je sustav, nad kojim se izvršavalo ispitivanje, opisan.
Analizom podataka dobio se uvid u veličine i ponašanje mjernih parametara. Konačni rezultati ispitivanja pokazuju da se gorivo može brže promijeniti ručno nego automatskim načinom prebacivanja. Također se saznalo da je ručno prebacivanje puno zahtjevnije, te da je potrebno više znanja i opreza kod takvog prebacivanja.This paper represents the research conducted about how the fuel oil change-over method has effect on specific fuel oil consumption, viscosity of fuel, fuel temperature and main engine parameters. All data has been presented analytically and graphically, and the system, on which the test was performed, has been described.
By analysis of collected data insight was provided into the magnitude and behavior of measured parameters. Final results of the test show that fuel can be changed over faster manually than automatically. It is also showed that manual fuel change over is more demanding, and it takes more knowledge and caution
Autonomous unmanned ships
No full textAutonomni brodovi, odnosno “pametni brodovi”, jesu brodovi budućnosti. Osmišljeni su kako bi mogli ploviti bez posade, što bi donijelo mnoge prednosti, poput smanjena ljudskih havarija, smanjena troškova i ostale prednosti. Na autonomnim brodovima radili su razni projekti poput MUNINA i AWAA projekta, budući da je danas tehnologija jako dostupna te se smatra da će korištenje umjetne inteligencije i senzora doprinijeti cjelokupnom razvoju brodarstva. Komunikacija autonomnih brodova odvijala bi se putem satelita, kao što su Inmarsat i Iridium te putem zemaljskih komunikacija u koje ubrajamo VHF radio, MF/HF radio i 4G/5G mrežu. Kako bi autonomni brodovi postali dio naše svakodnevice, njihova automatizacija mora biti prilagođena pravnim regulativama i normama. Iako su autonomni brodovi zamišljeni kao brodovi bez posade, njima će upravljati operateri putem kontrolnog centra.Autonomous ships or “smart ships”, are the ships of the future. They are designed to be able to sail without a crew, which would bring many advantages, such as reduced human damage, reduced costs and other advantages. Several projects such as the MUNIN and AWAA project have been worked on autonomous ships, since technology is very available today and it's believed that the use of artificial intelligence and sensors will contribute to overall development of shipping. The communication of autonomous ships would take place through satellites, such as Inmarsat and Iridium, and through terrestrial communications, which include VHF radio, MF/HF radio and 4G/5G network. In order for autonomous ships to become part of our everyday life must be adapted to legal regulations and norms. Although autonomous ships are envisioned as unmanned ships, they will be controlled by operators from the control center
Responsibility of the carrier for the damage to the goods
No full textU ovom se radu analizira i opisuje odgovornost prijevoznika za štete na teretu. U prvom dijelu rada opisuju se osnovni pojmovi, obilježja i značajke koje su bitne kako bi se pomorski prijevoz mogao ostvariti. Pažnja je usmjerena na ugovor o prijevozu stvari morem, te su njegovi dijelovi detaljno obrađeni.
U drugom dijelu rada obrađuju se međunarodne konvencije, pravni dokumenti, njihova povijest te kako se i na koji način danas uređuju odgovornosti prijevoznika za štete. U nastavku rad je usmjeren na odgovornost prijevoznika. Postavljaju se osnovna pitanja poput: što je šteta, kakva je odgovornost prijevoznika u odnosu na vrstu štete, kakve su posebnosti odgovornosti prijevoznika za štete na teretu u slučaju postojanja takozvanih iznimnih slučajeva u kojima prijevoznik neće odgovarati osim ako nije postupao bezobzirno. Na temelju rada zaključuje se neizmjerna važnost pomorskog prijevoza kao i potrebe donošenja nove konvencije koja će ga regulirati.This paper describes the responsibility of the carrier for damages to the cargo. The first part of the paper describes the basic concepts and characteristics that are essential in order for the transport to be realized. Attention is focused on the contract of carriage of goods by sea and the parts of it are dissected. The second part of the paper describes conventions, legal documents, their history and the way they regulate the carrier's responsibility for damages on the cargo today. In the further continuation of the work the focus is on the responsibility of the carrier. Several basic questions are asked and answered: What is damage, what is the responsibility of the carrier in relation to the type of damage, what are the unique characteristics of the responsibility that the carrier has when an exceptional case happens. The main conclusion of the paper is the significant importance of maritime transport and the needs of creating a new convention which is going to regulate it
Marine spatial planning in Croatia – legal and technical aspects
No full textThe introduction of marine spatial planning (hereafter: MSP) for Croatia is essential, considering the coastline length and the increasing usurpation of coastal and marine space. MSP is more than a process that regulates the activities on the sea. It is an analytical approach to the setup of human activities in the marine area. As a maritime country, Croatia has ratified the Protocol on Integrated Coastal Zone Management and undertook the obligations of the Barcelona Convention. However, an appropriate document has not yet been made that would enable quality management of marine space. MSP and its onshore version contribute to the establishment and development of various activities, taking into account environmental, natural, economic, and sociological criteria. MSP is a continuation of spatial planning of the mainland area and must undoubtedly consider the more expansive coastal environment and the activities there. One of the tools in marine area mapping is the Geographic Information System (GIS), which has proven to be a very high quality and effective tool, especially in decision-making processes.
The authors analyze the existing legal framework for marine spatial planning. Particular emphasis is placed on the obligations facing the Republic of Croatia to implement marine spatial planning. Given that the paper seeks to determine the advantages of MSP implementation using modern tools in marine area mapping, the authors in the third part discuss the benefits of using GIS as an acceptable tool in mapping marine space and provide recommendations for further actions
