Opis:
The ocean is a formation that has a volume and consists of a surface layer of water, a column, and a bottom. Visualization of the sea on a digital map is important to support the acceleration of marine spatial planning (MSP), which is generally two-dimensional on a flat plane. A marine cadastre is defined as an instrument used in managing spatial boundaries, which describes, visualizes, and realizes legally defined boundaries as well as rights, restrictions, and responsibilities related to activities in the marine environment. Therefore, visualization in 3D will open a wider perspective than conventional maps. The 3D marine cadastral system was built using the Penanjung Bay pilot project and the QGIS2ThreeJS plugin with JavaScript. The results obtained can provide a 3D visualization of the position and boundaries for each component of the marine cadastre in Penanjung Bay with a broader picture of the sea spatial layout in the region.

Opis:
Ship traffic is one of the factors that is presented in almost all of the existing grounding models, and is considered as one of the affecting factors on the likelihood of grounding accident. This effect in grounding accident is mostly accepted by the experts as a common sense or simply by just generalizing the ship‐ship collision cases to grounding accidents. There is no available research on the actual causal link between the ship traffic and grounding accident in the literature. In this paper, authors have utilized the statistical analysis on historical grounding accident data in the Gulf of Finland between the years 1989 and 2010 and the AIS data of the same area in year 2010, as the source of ship traffic data, to investigate the possible existence of any correlation between the ship traffic and the grounding accident. The results show that for the studied area (Gulf of Finland) there is no correlation between the traffic density and the grounding accident. However, the possibility of the existence of minor relation between the traffic distribution and grounding accident is shown by the result. This finding, however, needs further investigation for more clarification.

Opis:
Exhaust gases from engines of seagoing ships are the serious problem for environment. That is why the discussion in the matter is very important. One of means to minimise harmful substances emission to earth atmosphere is application of „ecological fuel" — natural gas or nuclear energy for ship propulsion. Natural gas is commonly used in onshore applications but is rarely applied in marine propulsion. Heavy Fuel Oil is the basic brand of fuel used onboard ofseagoing ships. Other kinds of fuel e.g. Diesel Oil or gas Oil are used on smaller ships with limited sailing range. The nuclear energy, due to high costs is used only on few types of warships and some icebreakers. A real means for minimising harmful substances in exhaust gases from ships engines is replacement of Heavy Fuel Oil by Natural gas. Nowadays, heavy oil is commonly used due to technical and logistic abilities and conservative attitude of ship owners. The necessity of improvement in the field of environment protection inclines towards wide application of Natural gas as marine fuel. Application power-plant novel type would break the traditionalism in the shipbuilding and the introduction novel generation ofshipping drives.

Opis:
For several years, marine tourism market has been experiencing a renaissance and is one of the fastest growing segment of the tourist economy. Strong competition on the marine carriers market forced them to seek out innovative products, and in the wake of that, their specialization, as well. At the same time, there has been a tendency to change a model of resting from passive lying in the Sun on aboard of the ships for an active participation in theme and profiled marine voyages. That caters to various customers’ needs and preferences. Owners of cruise vessels outdo each other in inventing the original theme offers for specific groups defined within: religious faiths, musical tastes, sport hobbies, health needs, or sexual orientation and many others. In both, polish and foreign literature, there is a noticeable lack, when it comes to a scientific approach to this phenomenon. In this light, it seems reasonable to take this topic of the research. The main aim of this article is an estimation of tenders in terms of theme cruises offered by marine carriers and making their generic classification. The research was realized using a method of desk research, a critical and comparative analysis of available literature, offers of marine tourist carriers, and also other scientific reports. Moreover, the author shows a list of criteria that could be implemented in the statistical researches of demand on theme cruises.

Opis:
Automatic Identification System (AIS) data is used for monitoring the movements of vessels live movements through instant transmission of vessel information while, at the same time, historical AIS data is used for marine traffic analysis by researchers. There are several methods and computer programs developed for the analysis of marine traffic by the use of AIS data. Combining the intersection algorithm proposed by Antonio (1992) and distance calculation method, this study develops a method to analyse vessel distribution on a selected cross sectional line (SCS) in the Northern Aegean Sea. As a complementary to the new methods proposed, a desktop application is developed in C# programming language to visualize the vessel distribution on the SCS line. SQL server is used for AIS data storage and analysis. The study is conducted over 7-day AIS data, specifically 2.382.469 rows and 42.884.442 data in total, belonging to the Northern Aegean Sea marine traffic. As a result, the mapping of the movements of different types of vessels in the Northern Aegean Sea is effectively performed and Frequency-Distance, Draught-Distance, SOG-Distance, SOG-COG distributions on the SCS line are successfully analysed by the new method introduced.

Opis:
Difficulty of sailing is quite subjective matter. It depends on various factors. Using Marine Traffic Simulation System (MTSS) developed by Osaka University this challenging subject is discussed. In this system realistic traffic flow including collision avoidance manoeuvres can be reproduced in a given area. Simulation is done for southward of Tokyo Bay, Strait of Singapore and off‐Shanghai area changing traffic volume from 5 or 50 to 150 or 200% of the present volume. As a result, strong proportional relation between near‐miss ratio and traffic density per hour per sailed area is found, independent on traffic volume, area size and configuration. The quantitative evaluation index of the difficulty of sailing, here called risk rate of the area is defined using thus defined traffic density and near‐miss ratio.

Opis:
The development of coastal infrastructure and related maritime transport necessitatesthe intensification of vessel traffic monitoring. Navigation systems used in this research are traditionally based on the information transmitted by radio waves. Marine traffic safety requires constant supervision carried out by dedicated systems, the operation of which may be limitedby difficult environmental conditions. The possibilities of supporting navigation systems with underwater observation systems are explored here. The research was carried out using an underwater measurement system. Local disturbances of the hydroacoustic and hydrodynamic field from the moving vessels were analysed. The potential for identifying a moving vessel, for example for offshore infrastructure security purposes, is demonstrated.

Opis:
Protecting and preserving the environment and marine resources is a constant concern of countries. The seas and oceans face increasing threats to their flora and fauna from pollution, both from land and sea sources. Overexploitation of marine resources and overfishing pose serious threats to biodiversity and the balance of marine ecosystems. Especially for countries that rely on fisheries resources to feed their populations in closed or semi-closed seas. It is unusual to highlight overfishing by ships, as coastal states' resources do not allow for effective safety controls and as a result, there are a number of severely depleted fisheries worldwide. It is therefore vital that conservation and management measures for straddling fish stocks and highly migratory fish stocks continue and increase, as it is a resource that has transcended many national jurisdictions. According to the priorities of the current research project, which include alignment and adaptation to the regulations of the Saudi marine environment, the research group of the current marine ecosystem project tries to analyze the variables contained in maritime transport and shipping and to measure the impact of these variables on the marine ecosystem, by focusing on four national priority areas: 1) reliable and long-term seafood supply; 2) thriving coastal ecosystems; 3) sustainable coastal development; and 4) risk resilience in coastal communities. Prioritizing coastal issues and gathering desired outcomes from.
