A key element in ensuring the safety of the port of Świnoujście against oil spills is to ensure combat units are properly equipped with oil spill collecting equipment, and that they have the ability to effectively use the existing resources. All of this should be properly reflected in the port’s contingency plans. It is also important to develop tactics for oil spill combat action that take into account both local conditions and worst case scenarios with parallel checking of these scenarios during the exercise and the table-top exercises. The use of computer simulation to forecast oil spill behaviour allows for better arrangement and more efficient use of resources and the optimum development of antipollution action and tactics. The specific location of the Świnoujście harbour, its breakwaters shape, and that shipping traffic is allowed only on the approaching waterway, may lead one to the conclusion that the port of Świnoujście is completely safe from any possible petroleum pollution after a ships’ collision and the antipollution action should focus only on maximising the protection of the coast. To verify this assumption, simulations of an oil spill spreading after a vessels’ collision were carried out. The purpose of the simulations was to determine the most unfavourable weather conditions which would lead to the port of Świnoujście being polluted, and to define the best tactics for conducting oil spill combat actions under such conditions. The simulations clearly indicated that, with a particular combination of weather conditions, pollution could occur inside the port. It could result in vessel traffic suspension and huge financial losses. Simulations were conducted using the PISCES II oil spill simulator.

The high volume transported by ro-ro vessels has not come without a price. Accidents and incidents related to design – lack of bulkheads, instability, problems with cargo access doors, stowage, securing cargo and lifesaving appliances – are growing along with the size of the vessels themselves. One particular and recurrent problem is the degree of these giant box-like high riding vessels exposed to wind. Recently the effect of a tramontana – a fierce, sudden and short term regional wind – in the Port of Koper was to detach a moored ship, causing an accident. This paper will present a study of that accident, and through simulations and modelling determine an improvement that will allow berthing perpendicular to the stern ramp to function more securely.

Cruise ships arriving in the port of Koper carry approximately 1000 to 3000 passengers and crew members. Such a concentration of people presents a high degree of risk in the event of a major disaster, because it is difficult to control, due to limited space, the dynamics of people in the event of a general panic, the presence of large amounts of fuel, proximity of the city center and other vessels and cargo at the port. To avoid the possibility of hazard events, a good safety assessment must be done prior to a ship’s arrival. One of the methodologies for systematically assessing the risk is a Formal Safety Assessment, a tool for determing and evaluating the risk of potential hazards at a cruise ship terminal. This paper discusses the diverse aspects of safety analysis.

Maritime surveillance from space is useful for many applications, such as fisheries control, maritime border control and maritime security. A new generation of satellite-borne Synthetic Aperture Radars is able to provide resolutions of down to 1 meter. In the case of maritime targets, however, their motions lead to blurring in the SAR images, so these high resolutions cannot be attained. Scientific research into how to surmount the existing limits on the use of high-resolution images for maritime surveillance would be of great utility. In this context, high resolution SAR data were collected from ships that have been fitted with motion sensors in order to understand vessel motion impact on detection and recognition capability.

The technological contributions to the reduction of piracy not only involve implementations of recent technological advances, but, importantly, the dissemination of the education required to apply current and future technologies, particularly in those states in the regions where piracy is rampant. To this end, the EU’s MARSIC project, with the stated aim of enhancing security and safety in the Gulf of Aden and the western Indian Ocean through ‘..information sharing and capacity building, (and) highlighting regional coop-eration’ (Marsic 1st monitoring report, 2010) has recently been inaugurated. The Faculty of Maritime Studies and Transport of the University of Ljubljana, and the Maritime University of Szczecin, as partners in this pro-ject, will bring to bear both the most advanced technological applications to maritime affairs of satellite im-agery, simulation, and risk assessment, and guarantee their utility through the transfer of knowledge. In Yem-en and Djibouti, maritime stations will be established, personnel trained, and a sustainable level of expertise eventually left in place. Interest in such projects has also been expressed by maritime experts in Tanzania and Kenya. The advantage this approach has over other donor-supported solutions begins with regional involve-ment and an inclusive approach, its ultimate success to a large degree dependant on factors external to the project such as financial incentives for the nations of the region to protect European and Far East Asian ship-ping. The project is closely coordinated with a parallel EU-funded project executed by European Commis-sion’s Joint Research Centre (JRC) on maritime surveillance technologies application in the region.

The efforts to maintain the relatively safe status of maritime transport are required, but unfortunately these efforts necessarily go beyond technological improvements to measures necessitated by intentional operational polluters. Science in this aspect is relegated to a defensive position, its direction dictated by environmental crime. The old practices of dumping ship-generated waste and pumping out cargo residues apparently will continue until a mean of identifying perpetrators is established and publicized. We hope that satellite technology can play an important complementary and supporting role in detecting and deterring such pollution. When an early-warning message can be delivered to responsible authorities (mainly coast guards) in real time, satellites can effectively support the possibility of identifying the polluting ship and thus open the way to prosecution of the offenders. This paper is about advances in polluter identification methodology beginning with the analysis of SAR images. Because cases in which a freshly released slick is detected are rare, an acquired image usually depicts a slick that is already weathered, with a currents-and-wind-distorted slick footprint and either no ships or too many ships in the vicinity. If AIS (Automatic Identification System) information is available or can be retrieved through an archive, in most cases the operator is still faces the problem that many ships passed the designated area, or that the slick is outside AIS range, effectively preventing any possibility of identification. Another problem related to polluter tracking is the availability of metocean ancillary data. Highly accurate wind and currents data are necessary for successful backtracking of the slick towards likely polluters and the origin of the spill. Wind and currents data therefore must be validated; for instance, by reading headings from anchored ships or analyzing the differences between integrated courses and headings of ships passing through the area under investigation. Drift caused by external forces for a certain vessel may be further validated through the use of a ship handling simulator.

Wymagane zabiegi mające na celu utrzymanie bezpiecznego statusu transportu morskiego muszą wykraczać poza ramy ulepszania środków technicznych, niezbędnych do wykrycia działań sprawców zanieczyszczeń na morzu. Nauka w tym aspekcie nie jest w pełni wykorzystana, a postępowanie w sprawie zdarzeń na morzu traktowane jest jako przestępstwa przeciwko środowisku. Dotychczasowe praktyki dumpingu odpadów wytwarzanych przez statki i wyrzucania pozostałości ładunków trwać będą najprawdopodobniej do momentu ustalenia i ujawnienia sprawców. Autorzy mają nadzieję, że technologia satelitarna będzie odgrywać ważną rolę w zakresie wykrywania i powstrzymywania zanieczyszczenia akwenów. Kiedy wiadomość wczesnego ostrzegania może być dostarczona do odpowiednich organów (głównie służby ochrony wybrzeża) w czasie rzeczywistym, satelity mogą skutecznie wspierać identyfikowanie zanieczyszczającego statku, a tym samym ułatwić ściganie przestępców. Niniejszy artykuł opisuje postępy w rozwoju metodologii identyfikacji sprawców zanieczyszczeń, począwszy od analizy obrazów SAR. Przypadki wykrycia świeżych wycieków są rzadkie - uzyskany obraz zwykle przedstawia wyciek, który jest już wyblakły, prądy morskie i wiatr zniekształcają pozostawiony ślad, w pobliżu jest wiele statków lub nie ma żadnego - i nawet gdy informacje z AIS (Automatyczny System Identyfikacji) są dostępne lub też mogą być pobrane z archiwum, to nadal w większości przypadków operator staje przed problemem uniemożliwiającym identyfikację. Inną trudnością, związaną z wyznaczeniem trasy statku zanieczyszczającego, jest dostępność dodatkowych danych. Bardzo dokładne dane o wiatrach i prądach są niezbędne dla skutecznego wyśledzenia potencjalnych trucicieli i źródeł wycieku. Informacje te muszą być potwierdzone, na przykład poprzez odczytanie kursów z zakotwiczonych jednostek lub analizy różnicy między zintegrowanym kursem i pozycją statków przepływających przez obszar objęty dochodzeniem. Dryf spowodowany przez siły zewnętrzne na określony statek może być potwierdzony za pomocą symulatora obsługi danej jednostki.
