The technology of transhipment, stowage, and securing cargo units on Ro-Ro ships
No full textNaslov ovog završnog rada je „Tehnologija prekrcaja, slaganje i učvršćivanje jedinica tereta na RO-RO brodovima.“ U radu je objašnjen povijesni razvoj RO-RO brodova, njihove karakteristike, kao i osnovna svojstva opreme za ukrcaj i prekrcaj jedinica tereta. Jedna od glavnih značajki svakog RO-RO broda su brodske rampe, jer se sav teret dovozi i odvozi upravo preko njih. Iz tog razloga bitno je naglasiti njihove osnovne karakteristike, ali i razvoj u budućnosti kako bi se poboljšala funkcionalnost RO-RO brodova. Jedinice tereta se mogu slagati na tri različita načina, što je detaljnije objašnjeno u samom radu. Prilikom slaganja i učvršćivanja tereta, od velike je važnosti poznavati osnove stabilnosti kako se ne bi ugrozila sigurnost ne samo tereta, već i cijelog broda. Pri završetku rada dan je primjer razvoja RO-RO brodova u Rapskoj plovidbi d.d.This thesis, titled “The technology of transhipment, stowage, and securing cargo units on Ro-Ro ships“ looks into the historical development of the Ro-Ro vessel, theirs characteristics, and basic features of equipment used in loading and transhipment of cargo units. One of the main features of every Ro-Ro ship are ship pumps, as these pumps are used for loading and unloading all cargo. It is important to emphasize not only the key characteristics of these ships but look into possibilities of further development as well, as to improve their overall functionality in the future. Cargo units can be stowed in three different ways, described more in details in this thesis. Understanding basic stability principles is of key importance during stowing and securing cargo, as to ensure the safety of not only the cargo, but the entire ship, as well. The development of a Ro-Ro ship owned by Rapska plovidba Ltd. is taken as an example at the end of the thesis
Wärtsilä 50DF engine UNIC C3 automation system
No full textSustavi nadzora i upravljanja za Wärtsilä motore razvili su se od 1970-ih, od vanjskog nadzora i alarmnih sustava do ugrađenog sustava upravljanja motorom. Oko 2002. godine stariji sustavi automatizacije postali su sve zahtjevniji za održavanje i nepodesni za daljnji razvoj. Stoga je donesena odluka o razvoju generičke platforme UNIC koja se danas upotrebljava na svim novoizgrađenim 4-taktnim motorima tvrtke Wärtsilä.
Razvojem sustava UNIC (eng. UNIfied Controls), prilagođenog Wärtsilä 50DF motorima, predstavljen je modularni i distribuirani, ugrađeni sustav nadzora i upravljanja motorom, cjelovit sustav upravljanja s izuzetnim mogućnostima prilagodbe i nadogradnje. Mogućnost nadogradnje upravljačkog sustava UNIC osigurava pouzdan, učinkovit rad i globalnu podršku za pomorske i kopnene energetske instalacije te donosi niz prednosti, uključujući poboljšanu dostupnost, efikasnost i produljeni životni ciklus motora te bolju podršku.
Daljnji razvoj i primjena sustava UNIC imati će sve važniju ulogu u budućnosti.Monitoring and control systems for Wärtsilä engines have evolved since the 1970s, from external monitoring and alarm systems to a built-in engine control system. Around 2002, older automation systems became increasingly demanding to maintain and unsuitable for further development. Therefore, the decision was taken to develop the generic UNIC platform, which is now used on all newly built 4-stroke Wärtsilä engines.
With the development of the UNIC (UNIfied Controls) system, used at Wärtsilä 50DF engines, Wärtsilä has presented a modular and distributed, built-in engine monitoring and control system, a complete control system with exceptional customization and upgrade capabilities. The ability to further upgrade the UNIC control system ensures reliable, efficient operation and global support for maritime and terrestrial energy installations and brings a number of advantages, including improved accessibility, efficiency and extended lifecycle of engines as well as better support.
Further development and implementation of UNIC control system will play an increasingly important role in the future
Pravni okvir odgovornosti brodara za smrt i tjelesne ozljede člana posade u angloameričkom pomorskom zakonodavstvu
No full textRazmatrajući pravno uređenje odgovornosti brodara za štetu zbog smrti i tjelesne ozljede člana posade u raznim nacionalnim zakonodavstvima, može se konstatirati kako se one temelje na potpuno različitim pravnim tradicijama, no zajednička im je crta da se status pomoraca regulirao odvojeno od statusa djelatnika na kopnu. Hrvatski pomorci plove na hrvatskim brodovima upisanim u hrvatske upisnike brodova i na brodovima pod zastavama drugih država, stoga dijele sudbinu s više od dva i pol milijuna pomoraca iz osamdesetak pomorskih država na svim svjetskim morima. Naravno, potrebno je istaknuti kako za sve te pomorce nisu važni samo propisi države njihova državljanstva ili prebivališta, nego i pravo države zastave broda, države luka u koje će brod uplovljavati te države u kojima je sjedište brodara. S obzirom na to da će u brojnim slučajevima ove države pripadati upravo angloameričkom pravnom krugu, u sudskim postupcima za naknadu štete pomorcima često će se primjenjivati njihovi pravni propisi. U ovom radu prikazana su neka od važnijih pravnih rješenja njihovih vodećih zakonodavstava.With regard to the legal regulation of the shipowner’s civil liability for damage caused by the death and personal injury of a crew member in various national legislations, although they are based on different legal traditions, their common feature is that the status of seafarers in most of these countries is regulated separately from the status of transport workers and other professions on land. Croatian seafarers sail on Croatian ships registered in the national register of ships, as well as on ships under the flags of other countries, sharing thus the fate of more than two and a half million seafarers from more than eighty maritime countries in all seas and oceans of the world. It is necessary to emphasise that for all these seafarers, the important legal framework is provided not only by the regulations of the State of their citizenship or their residence, but also by the law of the flag State of the ship, the port State where the ship enters, and the State where the shipowner is based. Having in mind that these countries in many cases belong to the Anglo-American legal area, causing the application of their legal regulations in court proceedings for compensation of damage to seafarers of all nationalities, including Croatian nationality, the paper presents some of the most important legal solutions of common law systems
Dynamic Smart Numbering of Modular Cargo Containers
No full textIn this paper, the authors identify the existence of container imbalance that occurs in different types of ports, depending on the type of inbound and outbound cargo they serve. The authors further analyze international trade realities and maritime companies’ requirements and identified inefficiencies. A comprehensive review of the relevant container regulations and identification standards is performed. Based on their findings, a paradigm change is proposed in the form of a modular container solution that uses disruptive digital technologies to ensure dynamic container identification (numbering) that can be exploited to overcome such inefficiencies. The technical requirements for coupling and decoupling operations are identified, along with detailed analysis of the requirements for embedded electronic components. Considering the strict container data exchange rules, the required changes in global container tracking systems are identified and explained. Coupling, decoupling, and serial number assignment procedures are proposed along with analysis of the measured lead times. Modularization and dynamic smart numbering are identified as viable disruptive technologies to address the global container imbalance. The authors contribute to the existing research on maritime transport sustainability by proposing a modular container solution, exploiting disruptive digital technologies, and clearly defining the prerequisites for the global introduction of the solution as a part of the digital transformation portfolio of involved stakeholders managing global container movements

No full textU ukupnoj greški položaja određenog satelitskim navigacijskim sustavima atmosfera sudjeluje s greškama uzrokovanim slojevima ionosfere i troposfere. Troposfera se smatra neutralnim medijem zbog istog učinka na faze signala vala nosioca i signala informacije. Greška položaja uzrokovana troposferskim djelovanjem (zajedničkog naziva troposfersko kašnjenje) mora se procijeniti prilikom određivanja položaja ili naknadno odrediti upotrebom vanjskih troposferskih popravaka. Najvažniji elementi koji uzrokuju troposfersko kašnjenje jesu atmosferski plinovi, tlak, temperatura te količina vode u atmosferi. Učinak troposferskog kašnjenja odvojeno se promatra u zenitnom smjeru te u nagibnom smjeru dolaznog satelitskog navigacijskog signala. Dodatno, troposfersko kašnjenje može se promatrati i s obzirom na atmosferske uzroke pri čemu se odvojeno promatraju hidrostatski (suhi) i nehidrostatski (mokri) uzroci. Kretanje troposferskog kašnjenja pokazuje dnevne, sezonske i godišnje zakonitosti. Na tim spoznajama razvijen je niz modela popravaka troposferskog kašnjenja različitog pristupa: samo u zenitnom smjeru po suhim i/ili mokrim uzrocima, odvojena funkcija mapiranja za nagibne smjerove po suhim i/ili mokrim uzrocima ili zajednički cjeloviti model. U disertaciji je predložen model temeljen na Saastamoinenovu modelu zenitnog troposferskog kašnjenja. Model je razvijen na temelju položajnih zapisa satelitskog navigacijskog sustava GLONASS te odgovarajućih meteoroloških ulaznih podataka unutar jedne godine s trima lokacijama. Predloženi model definira troposfersko odstupanje odvojeno za svaku položajnu os. Rezultati pokazuju da je predloženim modelom ostvarena statistička ravnoteža položajnih odstupanja GLONASS-a u funkciji zenitne komponente troposferskog kašnjenja. Provedenog verifikacija (na trima lokacijama u Republici Hrvatskoj unutar dvogodišnjeg razdoblja) pokazuje da predloženi model smanjuje zenitnu komponentu troposferskog kašnjenja čime poboljšava točnost položaja. Time je potvrđena prikladnost upotrebe predloženog modela na promatranom području te na širim područjima sličnog klimatskog profila. Vrednovanju predloženog modela pristupilo se s obzirom na početna ograničenja, polučene rezultate točnosti te na ostvarene spoznaje o troposferskoj dinamici promatranog područja. Uputilo se na potencijal praktične i znanstvene primjene ukupnih rezultata istraživanja. Prilagodljivost predloženog modela, uz istovremeno smanjivanje početnih ograničenja, predstavlja osnovu za buduća istraživanja troposferskog kašnjenja.In the overall position error determined by the satellite navigation systems, the atmosphere participates with errors caused by the ionosphere and troposphere layers. The troposphere is considered to be a neutral medium due to the same effect on the carrier phase and information signal phase. The position error caused by tropospheric effect (commonly called tropospheric delay) must be assessed while determining the position or subsequently determined using external tropospheric corrections. The most important elements that cause tropospheric delay are atmospheric gases, pressure, temperature and the amount of water in the atmosphere. The effect of tropospheric delay is observed separately in the zenith direction and in the slant direction of the incoming satellite navigation signal. Additionally, tropospheric delay can also be observed with regard to atmospheric causes, with hydrostatic (dry) and non-hydrostatic (wet) causes being observed separately. The movement of tropospheric delays shows daily, seasonal and annual regularities. Based on these findings, a number of tropospheric delay models of different approaches have been developed in the zenith direction only for dry and / or wet causes, a separate mapping function for slant directions for dry and / or wet causes, or a common overall model. In the dissertation, a model based on the Saastamoinen model of zenith tropospheric delay has been proposed. The model was developed based on the position records of the GLONASS satellite navigation system and appropriate meteorological input records within one year with three locations. The proposed model defines the tropospheric deviation separately for each position coordinate. The results show that the statistical equilibrium of positional GLONASS deviations in a function of the zenith component of the tropospheric delay has been achieved by the proposed model. The verification carried out (at three locations in the Republic of Croatia within a two-year period) shows that the proposed model reduces the zenith component of the tropospheric delay and thus improves the accuracy of the position. This confirmed the suitability of using the proposed model in the observed area and in wider areas of similar climate profile. The evaluation of the proposed model has been approached in the view of the initial limitations, the obtained accuracy results and the realized knowledge about the tropospheric dynamics of the observed area. The potential of practical and scientific application of the overall research results has been pointed out. The adaptability of the proposed model while reducing initial restrictions represents the basis for future tropospheric delay researches
Assesment of justification of the activities establishment in the coastal areas
No full textU obalnom prostoru odvijaju se gospodarske aktivnosti specifičnih interesa i prostornih potreba. Donošenje odluke o uspostavi djelatnosti u obalnom prostoru kompleksan je proces u kojem je potrebno razmotriti niz sukobljenih čimbenika. Osnovni cilj istraživanja je predložiti model za procjenu opravdanosti uspostave djelatnosti u obalnim područjima. Razvijenim modelom povezuju se svi čimbenici koji utječu na resurse obalnog, odnosno morskog područja. Analiza tih veza omogućuje definiranje kriterija i potkriterija za donošenje odluke o smještaju gospodarske djelatnosti u prostoru. Za uspostavu gospodarskih djelatnosti u obalnom području od ključne je važnosti izbor namjene prostora. Stoga je nužan metodološki pristup koji će osigurati razumnu razinu objektivnosti za izbor namjene prostora prije nego što odluka o uspostavi gospodarske djelatnosti uđe u politički proces. Za donošenja odluke o uspostavi djelatnosti u obalnom prostoru primijenjena je metoda višekriterijske analize, analitički hijerarhijski proces (AHP). Razmatrajući specifične interese odvijanja gospodarskih djelatnosti u obalnom području vidljivo je da neke gospodarske djelatnosti mogu lako koegzistirati u istom obalnom području, dok su neke nespojive s većinom drugih morskih namjena te u većoj ili manjoj mjeri, imaju ograničavajući utjecaj na druge djelatnosti. Za učinkovito upravljanju obalnim područjem treba u fokus staviti informacije o konfliktima između gospodarskih djelatnosti. Procjena mjere konfliktnosti gospodarskih djelatnosti u obalnom području predstavljena je matricom konfliktnosti. U cilju provjere modela provedeno je istraživanje anketnim upitnikom. Ekspertnom procjenom vrjednovani su kriteriji i potkriteriji za donošenje odluke o smještaju gospodarske djelatnosti u prostoru. Izabrani stručnjaci raspolažu odgovarajućim stručnim obrazovanjem, znanjem, vještinom i/ili iskustvom za procjenu koja se provodi. Kriteriji i potkriteriji kojima se procjenjivala opravdanost uspostave djelatnosti u obalnim područjima međusobno su uspoređeni u parovima, s ciljem određivanja težina, odnosno važnosti svakog od njih. Gospodarske djelatnosti ocjenjene su kroz utvrđivanje prioriteta, odnosno u kojoj mjeri zadovoljavaju svaki od definiranih kriterija i potkriterija. Intenziteti preferencija svakog sudionika istraživanja uneseni su u računalni program Expert Choice. Na osnovi individualnih ocjena stručnjaka, dobivena je sintetizirana prosudba što je rezultiralo donošenjem odluke o smještaju najprihvatljivije djelatnosti. Izabrano područje za testiranje modela je prostor uvale Žurkovo. Razvijena su tri scenarija: Scenarij 1 ˗ smještaj komunalne luke, Scenarij 2 ˗ smještaj luke nautičkog turizma ˗ marine te Scenarij 3 ˗ smještaj morskog zabavno-rekreacijskog centra i određena namjena korištenjem predložene metodologije. Najutjecajniji čimbenici prikazani su analizom osjetljivosti. Analizom osjetljivosti utvrđeno je u kojoj mjeri se najutjecajniji čimbenici odražavaju na ukupne prioritete alternativa. S obzirom na dobivene rezultate višekriterijske ocjene, planiranje uspostave djelatnosti važan je preduvjet za dugoročno i održivo odvijanje obalnih aktivnosti nekog prostora. Model predstavlja potporu donosiocima odluke pri planiranju dodjeljivanja obalnog prostora na korištenje te utvrđuje opravdanost smještaja gospodarske djelatnosti.The coastal zone is the site of various economic activities of specific interests and spatial needs. Making a decision to establish economic activities in the coastal area is a complex process in which a number of conflicting factors need to be considered. The main goal of the research is to propose a model that would assess the justification of establishing activities in coastal areas. The model developed connects all the factors that affect the resources of coastal and marine areas. The analysis of these connections enables the definition of criteria and sub-criteria for deciding on the location of a given economic activity in space. In order to establish economic activities in the coastal area, the key importance is to establish choice of area use. Therefore, a methodological approach is needed to ensure a reasonable level of objectivity to choose the purpose of economic activities of area before enetering the political process. The method of multicriteria analysis, analytical hierarchical process (AHP), was applied in making decisions on the establishment of activities in the coastal area. Considering the specific interests of economic activities in the coastal area, it is clear that some economic activities can easily coexist in the same coastal area, while some are incompatible with other marine activities, and have more or less a limiting effect on it. In order to stress effective coastal zone management, the focus should be on gathered information about conflicts between economic activities. The assessment of the measure by economic activities conflict in the coastal area is presented by the conflict matrix. In order to verify the model, a survey with a questionnaire was conducted. The criteria and sub-criteria for deciding on the location of an economic activity in area were evaluated by expert assessment. The selected experts have the professional education, knowledge, skills and/or experience that is appropriate for the assessment carried out. Criteria and sub-criteria that assessed the justification for the establishment of activities in coastal areas were mutually compared in pairs, with the aim of determining the weight, namely the importance of each of them. Economic activities are assessed through the determination of priorities, namely, the extent to which they meet each of the defined criteria and sub-criteria. The preference intensities of each study participant were entered into the Expert Choice computer program. Based on the individual assessments of experts, a synthesized judgment was obtained, which resulted in a decision on the location of the most acceptable activity. The area chosen for model testing is the area of Žurkovo Bay. Three scenarios have been developed: Scenario 1 ˗ establishment of a communal port, Scenario 2 ˗ establishment of a nautical tourism port ˗ marina, and Scenario 3 ˗ establishment of a sea entertainment and recreation centre, so the purpose is determined by using the proposed methodology. The most influential factors are presented by Sensitivity Analysis, which identified the extent to which the most influential factors are reflected in the overall priorities of the alternatives. Given the obtained results of the multi-criteria evaluation, planning the establishment of activities is an important prerequisite for long-term and sustainable development of coastal activities in an area. The model represents support to decision makers in planning the allocation of coastal space for use and determines the justification of the location of economic activity

Supply chain managment : Royal Caribbean Group
No full textUpravljanje logistikom kod brodovima na kružnim putovanjimaje za svako putovanje, logistika krstarenja "iza kulisa" proteže se dalje od usklađenosti i doslovce dopire do svakog kutka ovih ogromnih plovila...i do regija u kojima posluju, do ljudi koje zapošljavaju i korisnika usluga kojima služe. Sve, od ulaznog i izlaznog upravljanja opskrbom do distribucije gotovih proizvoda do procesa slijetanja, mora biti precizno orkestrirano i upravljano na najneometaniji mogući način. Istražujemo koje su distribucijski oslonci Royal Caribbean Group-e i kako ona upravlja svojim resursima. Problematika svakog broda na kružnim putovanjima je najviše u tome kako regulative predstavljaju prepreku u svakodnevnom životu i s time se nastoji uskladiti sa drugim zemljama, zajedno sa rasporedama plovidbe i putnicima. U ovom radu istražujemo Royal Caribbean Group kako se oporavlja od takvih prepreka postavljenih radi nedavnoh COVID-19 i nastavlja sa daljnim radom.Logistics management in cruise companies is for every trip, cruise logistics "behind the scenes" extends beyond compliance and literally reaches every corner of these huge vessels...and to the regions in which they operate, to the people they employ and the users of the services they serve. Everything from inbound and outbound supply management to distribution of finished goods to the landing process must be precisely orchestrated and managed in the most seamless manner possible. We are investigating what are the distribution pillars of a kucer company and how it manages its resources. The problem of every cruise company is mainly that the regulations represent an obstacle in everyday life, and with that they try to harmonize with other countries, together with sailing schedules and passengers. In this paper, we explore how the Royal Caribbean Group is recovering from such obstacles posed by the recent COVID-19 and moving forward
Properties and oil analysis in the transformer industry
No full textTransformatorska ulja osiguravaju pouzdan rad transformatora tijekom njegovog
životnog vijeka. Glavna uloga ulja u transformatorima je da služe kao medij za hlađenje i kao
izolacijski materijal. Kao najčešće upotrebljavana ulja koriste se mineralna ulja zbog iznimno
dobrih električnih i toplinskih svojstava te cijene. U novije vrijeme sve se više upotrebljavaju i
esterska ulja zbog visoke otpornosti na temperaturu i biorazgradivosti.
Visoki sadržaj vlage u izolacijskim materijalima može prouzrokovati značajne štete u
radu transformatora. Da bi se izbjegli štetni utjecaji vlage, transformator je potrebno osušiti i
smanjiti mu sadržaj vlage ispod 1%. Jedna od najučinkovitijih metoda sušenja koja se danas
koristi je sušenje kerozinskim parama. Princip sušenja se temelji na iskorištenju topline
kondenzacije kerozina.
Da bi se ulje moglo koristiti u transformatoru mora zadovoljiti različita svojstva. Glavna
svojstava transformatorskog ulja su: svojstva bitna za hlađenje (viskoznost, točka stiništa),
svojstva bitna za izolaciju (BDV, sadržaj vode), DGA. Prije upotrebe transformatorsko ulje je
potrebno obraditi kako bi se sadržaj nečistoća, vode i plinova doveo u odgovarajuće granice.
Nakon obrade ulje mora imati sadržaj vode 60 kV.
Redovno ispitivanje fizikalno-kemijskih i dielektričnih svojstava ulja od iznimne je
važnosti na životni vijek transformatora. Ispitivanja transformatorskog ulja provode se prije
puštanja u pogon te u različitim periodima eksploatacije. Najčešće se ispituje sadržaj vode u
ulju, probojni napon te kromatografska analiza plinova u ulju. Pomoću navedenih ispitivanja
dobiva se jasna slika stanja transformatora.Transformer oil ensure the reliable operation of the transformer during its lifetime. The
main purpose of oil in transformer: as a cooling media and an insulating material. The most
commonly used oils are mineral oil due to their good electrical and thermal properties and price.
Nowadays, ester oil are increasingly used due to their high temperature resistance and
biodegradability.
High moisture content in insulating materials can cause significant damage to the
transformer. In order to avoid the harmful effects of moisture, the transformer must be dried
and the moisture content reduced below 1%. One of the most effective drying methods used
today is vapor phase drying. The drying principle is based on the use of solvent condensation
heat.
In order for the oil to be used in a transformer, it must fulfill various properties. The
main properties of the transformer oil are: properties essential for cooling ( viscosity, pour
point), properties essential for insulation (BDV, water content), DGA. Before use, the
transformer oil must be treated. After the treatment, the oil must have a water content < 10 ppm,
gases 60 kV.
Regular tests of the physico-chemical and dielectric properties of the oil is important for
the lifetime of the transformer. The transformer oil tests are carried out before commissioning
and in different periods of exploitation. The water content in the oil, the breakdown voltage and
the chromatographic analysis of the gases in the oil are most often tested. With the help of the
mentioned tests, a clear picture of the state of the transformer is obtained
