Action Plan for HNS Pullution Preparedness and Response
No full textOnečišćenje mora s brodova i zaštita morskog okoliša aktualna su svjetska tematika i problematika. Štetne tvari koje su najzastupljenije u pomorskom prometu, predstavljaju ozbiljnu prijetnju i odgovornosti ukoliko se ne skladište i ako se njima ne rukuje na propisan način. Međunarodna konvencija o sprječavanju onečišćenja mora s brodova (MARPOL) i Međunarodna konvencija o zaštiti ljudskih života na moru (SOLAS) predstavljaju temelj kojima se određuju pravila, odredbe i postupci rukovanja štetnim tvarima. Pored konvencija, postoje i akcijski planovi čija je svrha upravo izrada planova reagiranja na onečišćenje s podjelom odgovornosti, kao i detaljnih opisa svih metoda i postupaka intervencije, te naravno sredstva i opreme, sukladno vrsti i tipu štetne tvari. S obzirom na navedeno i istraženo cilj rada je ukazati na važnost pripravnosti i brze reakcije kod nesreća koje uključuju štetne tvari, a u cilju smanjenja onečišćenja morskog okoliša s brodova.Marine pollution from ships and the protection of the marine environment are current world issues and problems. Harmful substances, which are most prevalent in maritime transport, pose a serious threat and liability if not stored and handled in the prescribed manner. The MARPOL and SOLAS Conventions are basis for the determination of the rules, regulations and procedures for the handling of harmful substances. In addition to the convention, there are action plans whose purpose is to develop pollution response plans with shared responsibility, as well as detailed descriptions of all methods and procedures of intervention, of course means and equipment, the appropriate type and type of harmful substances. Considering the stated and researched goal of the work, the importance of preparedness and quick reaction in case of accidents involving harmful substances was pointed out, in order to reduce the pollution of the marine environment from ships
Fibonacci sequence
No full textOd početka ljudske povijesti primijećena je pojava matematike i povezanost brojeva sa stvaranjem svega što okružuje ljudsko biće. Uska povezanost matematike i prirode oduvijek je postojala i prije nego što su je ljudi počeli istraživati. Razvoj čovječanstva uvelike je utjecao i na sam razvoj matematike kao znanosti. Brojevni sustavi i numeriranje dolazi u kasnijoj povijesti s potrebom kompleksnije matematičke komunikacije. Pojavom brojevnih sustava dolazi potreba za jasnijim pisanjem i razumijevanjem sustava. Fibonaccijevi brojevi i sustav jedni su od tih sustava koji su opisani u ovom radu. Izvedene formule potječu od svojstava Fibonaccijevih brojeva i služe za lakše računanje unutar samog sustava. Cilj ovog rada je ponajprije upoznavanje sa Fibonaccijevim brojevima i nizom, kao i opisivanje zanimljivih pojava tih brojeva u prirodi i povijesti.From the beginning of human history, the appearance of mathematics and the connection of numbers with the creation of everything that surrounds a human being has been noticed. The close connection between mathematics and nature has always existed even before humans began to explore it. The development of mankind has greatly influenced the very development of mathematics as a science. Number systems and numbering come in later history with the need for more complex mathematical communication. With the appearance of number systems comes the need for clearer writing and understanding of said systems. Fibonacci numbers and its system are one of those systems described in this paper. The derived formulas are formed from the properties of Fibonacci numbers and serve to facilitate computations within the system itself. The aim of this paper is primarily to get acquainted with Fibonacci numbers and series, as well as to describe interesting phenomena of these numbers in nature and history
Overwiew of incidents connected with life saving equipment handling
No full textOprema za spašavanje je jedan od najznačajnijih segmenata za zaštitu ljudskih života na moru. Zato je Međunarodna pomorska organizacija (engl. International Maritime Organization - IMO) donijela propise u Međunarodnoj konvenciji za zaštitu ljudskih života na moru (engl. Safety of Life at Sea - SOLAS) i pravilniku o sredstvima za spašavanje (engl. Life-Saving Appliances – LSA CODE). Na taj način standardizirana je oprema za spašavanje i uređaji za rukovanje tom opremom. Unatoč stalnom razvoju propisa i opreme prilikom rukovanja uređajima za dizanje i spuštanje opreme dolazi do nezgoda koje često uzrokuju smrtno stradavanje i teške ozljede članova posada brodova. U radu se daje kratak prikaz međunarodnih propisa i pregled službeno analiziranih pomorskih nesreća koje su se dogodile pri rukovanju sredstvima za spašavanje.Safety equipment is one of the most important segments for the protection of human lives at sea. The International Maritime Organization (IMO) has enacted regulations according to the International Convention for the Safety of Life at Sea (SOLAS) and the Life-Saving Appliances (LSA CODE) which enables the standardization of the life-saving appliances and devices for their handling and operation. Despite the constant development of regulations and equipment, accidents occur during the operation of lifting and lowering the equipment which often causes fatalities and serious injuries to crew members. This paper gives a brief overview of international regulations and officially analyzed maritime accidents that occurred during the handling of the safety equipment
Marine diesel engine fuel oil system
No full textU završnom radu se objašnjava sustav goriva brodskih dizelskih motora. Za porivne sustave broda kao pogonsko gorivo sluţe tekuća i u novije vrijeme plinovita goriva. Tekuća goriva mogu biti preraĎevine nafte ili se mogu dobiti na umjetan način iz krutih goriva ili organskih tvari. Plinovita goriva mogu biti prirodna, kao npr. zemni plin, a dobivaju se i preradom sirove nafte način. Za pogon porivnih i pomoćnih strojeva još uvijek su najvaţnija i najčešća u primjeni tekuća goriva. Razvijanjem pomorstva i brodskih motora dolazi do veće potraţnje za brodskim gorivom. Za pogon, veliki brodski dizelski motori najčešće upotrebljavaju teška brodska goriva iz razloga što su jeftinija od dizelskih goriva. Sustav goriva na brodu se sastoji od različitih podsustava koji su meĎusobno povezani. Osnovni cilj brodskog sustava goriva je pripremiti i osigurati dovoljnu količinu goriva. Brodski sustav se sastoji od ustava ukrcaja i transfera goriva, sustava skladištenja goriva, sustava pročišćivanja goriva te sustava dobave i ubrizgavanja goriva.The final paper explains the fuel system of marine diesel engines. Liquid and, more recently, gaseous fuels are used as propulsion fuel for ship propulsion systems. Liquid fuels can be petroleum products or can be obtained artificially from solid fuels or organic substances. Gaseous fuels can be natural, such as natural gas, and are also obtained artificially. With the development of maritime and marine engines, there is a greater demand for marine fuel Liquid fuels are still the most important and most common in the application of propulsion and auxiliary machines. Large marine diesel engines most often use heavy fuels for propulsion because they are cheaper than diesel fuels. The fuel system on board consists of different subsystems that are interconnected. The main goal of a marine fuel system is to prepare and provide a sufficient amount of fuel. The ship's system consists of the constitution of loading and transfer of fuel, the constitution of fuel storage, the constitution of fuel purification and the system of fuel supply and injection
Risks of hydrogen sulfide poisoning on board
No full textOtrovi su tvari koje mogu uzrokovati privremeno ili trajno oštećenje ako se unesu ili resorbiraju u tijelo u dovoljnoj količini. Trovanja mogu biti akutna (trovanja koja nastaju naglo), ili kronična (nastaju postupno, tijekom dužeg unošenja otrova u organizam). Otrovi na brodu mogu biti otrovi koji se svakodnevno koriste, otrovi koji mogu nastati u brodskim pogonima tijekom radnih postupaka, odnosno brodskih tereta. U ovom radu analizirano je otrovanje sumporovodikom (H2S), plin kojeg često nailazimo na brodovima. Ukoliko je čovjek izložen velikim koncentracijama sumporovodika, može doći do ozbiljnih posljedica za zdravlje, pa čak i smrt. Plin ima jaki miris pokvarenih jaja čak i kada mu je koncentracija niska, pa ga je vrlo lako prepoznati u ranom izlaganju, no ne smijemo ga zanemariti. U radu je opisan plin sumporovodik, njegova svojstva, mjesta na kojima se može naći i mjere zaštite kojih se treba pridržavati pri rukovanju sa ovim plinom, te mjere prevencije koje treba znati dođe li do kontakta.Toxins are substances that can cause temporary or permanent damage if ingested or resorbed in sufficient quantities. Poisoning can be acute (poisoning that occurs suddenly), or chronic (occurring gradually, during prolonged intake of toxins into the body). Toxins on board can be poisons that are used in daily basis, poisons that can be generated in ship’s facilities during work procedures, in ship’s cargo.
In this work, we analyze hydrogen sulfide (H₂S) poisoning, a gas often encountered on ships. If a person is exposed to an excessive amount of this harmful gas, it can have serious consequences for health and even death. The gas has a pronounced smell of rotten eggs even when its concentration is low, so it is very easy to recognize in early exposure, but we must not neglect it in any way. This work describes how to identify hydrogen sulfide, places and procedures to follow when handling this gas, and prevention measures to know if contact occurs
Importance of mathematics in marine engineers education
No full textPomorstvo i pomorske djelatnosti obavljaju se na više od tri četvrtine površine svijeta te su jedna od većih industrija današnjice. Od samih početaka brodostrojarstvo i matematika su povezane znanosti. Upotreba i održavanje brodova, te strojeva i sustava na njima, doveli su do velike ovisnosti o matematičkim načelima ili modelima. Međutim, ti modeli teško dolaze u obliku „čiste“ matematike, već su ugrađeni u znanosti koje se, opet, razvijaju zbog matematike. Ovaj rad je imao za cilj istražiti korisnost matematike u obrazovanju brodostrojara. U radu se raspravlja o različitim znanostima tj. predmetima u kojima se brodostrojari susreću s uporabom i primjenom matematike. U radu se također identificiraju posebne vrste ili područja matematike koje brodostrojari koriste kako bi savladali gradivo te se adekvatno obrazovali.Maritime and maritime activities are performed on more than three-quarters of the world’s surface and they are one of the biggest industries of today. From the very beginning, maritime engineering and mathematics have been related sciences. The use and maintenance of ships, machinery and systems on them, led to a greater dependence on mathematical principles or models. However, these models hardly come in the form of “pure” mathematics, but are already embedded in sciences that, in turn, are evolving because of mathematics. This paper aimed to explore the importance of mathematics in the education of maritime engineers. The paper discusses various sciences, i.e. subjects in which ship engineers encounter the use and application of mathematics. The paper also identifies special types or areas of mathematics that ship engineers use to master the material and be adequately educated
The impact of Sars-cov-2 virus and Covid-19 disease on the mental health of seafarers
No full textMentalno zdravlje pomoraca čest je predmet rasprava. I bez pojave pandemije i bolesti Covid-19, pomorci su bili izloženi prekomjernom stresu i raznim situacijama koje su narušavale njihovo mentalno zdravlje. Prekomjerni boravak na moru uzrokuje stres kod pomoraca, jer su udaljeni od kopna i svakodnevnog života, nedostaju im obitelj i prijatelji, nemaju dovoljno vremena za privatne slobodne aktivnosti i odmor, a često su izloženi i različitim opasnostima. Cilj rada je istražiti kako je pandemija virusa Covid-19 utjecala na mentalno zdravlje pomoraca. Istraživanje je pokazalo kako se pandemija negativno odrazila na mentalno zdravlje pomoraca te da postoji potreba za većom kontrolom mentalnog zdravlja i pružanja pomoći pomorcima kojima je to potrebno.The mental health of seafarers is a frequent subject of debate. And without the onset of the Covid-19 pandemic and disease, seafarers were exposed to excessive stress and various situations that impaired their mental health. Excessive stay at sea causes stress for seafarers, because they are far from the mainland and everyday life, they lack family and friends, they do not have enough time for private leisure activities and rest, and they are often exposed to various dangers. The aim of this paper is to investigate how the Covid-19 virus pandemic affected the mental health of seafarers. Research has shown that the pandemic has had a negative impact on the mental health of seafarers and that there is a need for greater control of mental health and the provision of assistance to seafarers in need

Cilj je rada analizirati temeljne odrednice i sadašnje stanje morskog putničkog prometa u Republici Hrvatskoj i međuodnos tog prometa s morskim putničkim lukama te utvrditi strategije razvoja morskog putničkog prometa u Republici Hrvatskoj u bližoj budućnosti. U radu se analiziraju obalni linijski putnički promet, putnički promet za kružna putovanja, kao i brodovi kojima se obavljaju te vrste prijevoza putnika. Također se analizira odnos morskog putničkog prometa s morskim putničkim lukama. Naglašava se i povezanost morskog putničkog prometa i turizma. Daje se pregled i glavnih nalaza te posebnih ciljeva i mjera donesenih u Strategiji prometnog razvoja Republike Hrvatske (2017. – 2030.). Za dugoročan razvoj morskog putničkog prometa treba modernizirati i proširiti morske putničke luke, modernizirati flotu putničkih brodova te poboljšati povezanost lokalnog i pomorskog javnog prijevoza s ciljem olakšavanja putovanja putnicima.The subject of this paper is maritime passenger traffic in the Republic of Croatia. This is a special type of passenger transport that involves the organized transport of passengers and goods by sea on special ships. The aim of this paper is to analyze the basic determinants and the current state of maritime passenger traffic in the Republic of Croatia and the relationship of this traffic with sea passenger ports and to determine strategies for the development of maritime passenger traffic in the Republic of Croatia in the near future. The paper analyzes coastal liner passenger traffic, cruise passenger traffic, as well as ships that perform these types of passenger transport. The relationship of sea passenger traffic with sea passenger ports is also analyzed. The connection between sea passenger traffic and tourism is also emphasized. In this paper is also given an overview of the main findings and specific goals and measures adopted in the Transport Development Strategy of the Republic of Croatia (2017 - 2030). For the long-term development of maritime passenger traffic it is necessary to modernize and expand sea passenger ports, modernize the fleet of passenger ships and improve the connection of local and maritime public transport in order to facilitate travel for passengers
The importance of determining place of shelter in the protection or the marine environment
No full textU ovome završnom radu definira se i objašnjava pojam mjesta zakloništa za brodove u nevolji te važnost određivanja mjesta zakloništa za morski okoliš. Zbog utjecaja suvremene pomorske plovidbe na morski okoliš, posebno onog negativnog uslijed pomorskih nesreća, u drugoj polovici dvadesetog stoljeća usvojene su različite međunarodne konvencije te brojni drugi međunarodni propisi (direktive, reolucije) koji su u nacionalno zakonodavstvo implementirani zakonima i podzakonskim propisima. Svi su ti propisi doneseni kako bi preventivno ili represivno djelovali na sudionike u pomorskom prometu s ciljem smanjivanja negativnog učinka na morski okoliš. U radu se posebno prikazuje pristup međunarodne zajednice, Europske unije i Republike Hrvatske u rješavanju problematike mjesta zakloništa.This final paper defines and explains the concept of a place of refuge for ships in distress and the importance of determining a shelter location for the marine environment. Due to the impact of modern maritime navigation on the marine environment, particularly the one negative due to maritime accidents, different international conventions and many other international regulations (directives, recursions) implemented in national law by subordinate legislation were adopted in the second half of the twentieth century. All these regulations have been adopted to act preventively or repressively on participants in maritime transport with a view to reducing the negative impact on the marine environment. This paper deals with the approach of the international community, the European Union and the Republic of Croatia in solving the problem of places of refug
