Opis:
The Baltic Sea area has already been intensively used by variety of maritime economic sectors such as marine transport, fishing, tourism, extraction of sand and gravel and oil and gas exploitation. This is also an area of relatively intense military penetration. In addition, this is a place of various other investments, e.g. coastal technical infrastructure (port and transhipment terminals constructions, as well as technical measures of the shoreline defence against transgression of the sea), electrical energy transmission systems (high voltage cables plus large scale electrodes) and natural gas transmission huge pipelines. Over the next decades, the use of the Baltic Sea will expand rapidly, particularly due to constructions of new coastal and offshore wind farms, electrical energy transfer network, further intensification of various forms of shipping, development and construction of new ports and terminals and installing new oil extraction platforms. Some of these activities influences natural spatial distribution of physical properties of the sea space (such as acoustic field, magnetic field, salinity distribution etc.) as well as disturb different natural processes (such as natural coastal dynamics, sedimentation, migration patterns of mobile species etc). In order to present this problem, most important existing activities as well as the most recent large-scale constructions in the Baltic Sea are selected and presented in this study (with emphasis on the Polish Exclusive Economic Zone). Moreover most likely disturbances of natural distributions of physical properties of marine space are analyzed in light of the impact on the environment

Opis:
Shiporigin operational discharges of oil mainly include the discharge of bilge water from motor rooms, fuel oil sludge and oily ballast water from fuel tanks. Also, various tankers can illegally discharge of tank-washing residues. Accidental discharges can appear when ship collide or come in distress at sea (e.g. engine breakdown, fire, explosion, pipeline breaks). There is necessity of continuous inspection of marine shipping routes, especially in environmentally sensitive areas (e.g. whole Baltic Sea). If protection against oil pollution is considered - the coastal nations of the North Sea are formed in the Bonn Agreement, whereas coastal nations of the Baltic Sea are formed in the HELCOM convention. Both organizations carrying out the international aerial surveillances and manage international oil-combat systems. Unfortunately, air surveillance can operate mainly in good weather, good visibility and in daylight. The surface of the whole world is observed independently on the time of day and weather by antennas of Synthetic Aperture Radars (SAR) of dozen military satellites with resolution of several meters. Some civil satellites equipped with SAR, supply every few days a set of signals which in ground-based centres are transformed to image of a define area of the sea surface. In these images, the shapes of places, which can be interpreted as polluted by an oil film, are shown. The system is introduced after EU directive and managed by European Maritime Safety Agency (EMSA). EMSA has developed the CleanSeaNet service - a satellite based monitoring system for marine oil spill detection. Advantages and limitations of the SAR-methods are discussed in this study. Physical, meteorological and hydrological as well as organizational conditions for effective use of this system are considered.

Opis:
The fast development of marine transport causes a lot of environmental concerns connected with possible accidents of ships transporting hazardous cargoes as well as oil pollution coming from an exploitation of engine rooms. Moreover, a significant problem is connected with a ballast water handling. The use of ballast water is necessary for the safe movement of large ships. Namely, in maritime transport a ship unloading causes a reduction in its draft - it is a cause of lower steering or even completely prevents the safe movement of the ship. Therefore, in place of the discharged freight the ballast water is collected (often just during the unloading). This water is pumped out from a ship at the site of re-loading. However, this implies the risk of transportation of living organisms over large distances, which (if at the point of discharge of ballast water will find suitable conditions) can become invasive species. Because of the risks involved in carriage of these organisms, the International Maritime Organization (IMO) has developed rigorous standards for permissible amounts of organisms in the discharged ballast water. A number of methods of biological neutralization of ballast water, that meet the requirements of the IMO, have been developed. The topic of this paper is to review currently used methods of neutralization of ballast water. We consider clearing of ballast water from point of view of physics, especially by using electromagnetic radiation and ultrasonic waves.

A sea voyage can be divided into three parts with varying degrees of risk: • from the berth at the port of departure to the pilot disembarkation point • from the pilot disembarkation to another pilot embarkation point near the port of call/destination • from the pilot embarkation point to the berth Results of statistical research into ship accidents at sea point to an increased number of incidents and accidents, including groundings, especially in restricted areas. Such areas are often narrow and have limited depths, while their short straight sections require frequent course alterations, often in varying hydrometeorological conditions. Due to all these factors, the voyage has to be carefully planned and all watchkeeping officers have to be well prepared to conduct the ship safely. The article presents the objectives, scope, legal basis and stages in the process of voyage planning. The compliance with the outlined principles will reduce the level of risk in maritime transport.

Opis:
The Baltic Sea belongs to a global system of protected area and has a status of Particularly Sensitive Sea Area (PSSA) which results in a mechanism for strict control on International shipping activities within designated areas through the UN International Maritime Organization (IMO). Countries can declare such areas, and then establish rules for their protection. Additionaly almost the entire Polish coastline has been notified to the European Natura 2000 sites. Inside coastal NATURA 2000 areas some places are covered by increased protection because of belonging to a system of coastal and marine Baltic Sea Protected Areas (HELCOM BSPA). On the other hand intensive shiping in the vicinity of the Polish coast, high population density in the coast, tourism as well as coastal and marine industry necessitate special attention in relation to environment protection. Therefore, inter alia, novel techniques for the surveillance of purity of coast and coastal water are desirable. In the case of large spill - existing combating system provides only partly reducing ofamount of oil entering the sea environment. Elimination ofa greatest number of small oil spillages or discharges is possible, if well developed techniques and organization systems is used. The paper presents pre-project assumptions for small multifunctional ship designed for inshore activity — especially for port inspections and service, as well as for removal of floating and submerged rubbish and combating small oil spillages. We have analyzed possibility to achieve expected exploitive features of the ship using present knowledge for construction of small ship hulls applying principles of engine and navigational equipment steeringfor choosing the best route and for optimization the water surface cleaning-works as well as to minimize the energy consumption. We expect, that this ship - owing to main designations thanks to modern technical equipment and sophisticated software -will also fulfill conditions as an educational or as a training vessel.

Opis:
The escalating maritime transport as well as offshore crude oil exploitation and pipeline transportation leads to the increase of feasibility of the discharge of petroleum substances to the sea environment events. Therefore, it is necessary to rapidly detect of oil pollution to minimize the extent of contamination in the seawater. The aim of this study is to discuss the assumptions of the optical methods using for detection of oil pollution in the seawater. We consider the different approaches of oil-in-water detection using spectral active and passive techniques with emphasis on fluorescence techniques. The intensive development of scientific apparatus and methods in light spectroscopy leads to build various airborne or underwater specialized devices (UV-, IR-scanners, fluorosensors), which allows to detect oil pollution in relatively large areas of the sea. The possibility of measurements of oil pollution in the seawater is particularly important for monitoring, especially in very difficult weather conditions and highly waved sea surface. Such possibilities should be given by devices for in-situ measurements based on time-resolved fluorescence. Such measurements allow obtaining the significant information about presence of oil in really short time. As we show in this study, the wide-range development of fluorescence techniques opens the diagnostic opportunity not only for detection of the oil-in-water content but also for identification the type of oil directly in seawater or even determination of the source of oil pollution.

To determine a time between subordinated vessels leaving the intersection a convolution operation has been used. The main factor disturbing the traffic stream of subordinated units is speed reduction on the intersection area. To model times needed to speed changes a normal distribution has been used.
Niniejszy artykuł dotyczy zaburzonego ruchu statków, przechodzących przez skrzyżowanie dróg wodnych. Do wyznaczenia czasu pomiędzy jednostkami podporządkowanymi, opuszczającymi skrzyżowanie wykorzystano operację splotu. Głównym czynnikiem zaburzającym strumień ruchu jednostek podporządkowanych jest ograniczenie prędkości na obszarze skrzyżowania. Do modelowania niezbędnych czasów, w których następują zmiany prędkości, wykorzystano rozkład normalny.

Opis:
Growing intensity of marine transport results in the increase of the amount of oil pollution released into the sea water. The presence of oil in the sea, which is thought to have come from accidental spills or tanker disaster, is connected mainly with the daily operation of marine engines. Pollution from ships engines, can reach the sea water masses together with ballast or bilge water as the result of human error or a failure of marine equipment. This paper is focused on a comparison of the optical properties of marine waters and oil substances. These include the spectra of absorption coefficient, spectra of scattering coefficient and scattering phase-function (for different wavelength) which describes an angular distribution of scattered light intensity in the sea water. The light scattering phase function depends on the water constituents like mineral suspensions, zooplankton and phytoplankton cells, gas bubbles or so-called yellow substances as well as oil droplets of water pollution. Detection of oil substances in the sea can be effective when it is done remotely, from ships, buoys, inshore or offshore towers, the decks of aircraft or satellites. The knowledge of the listed above properties of natural (clean) seawater is necessary, because they determine the field of light coming out from the sea and allow interpret images of sea surface from point of view of crude oil and the petroleum products detection. In this study we also discuss optical contrast of oil residuals in the sea in various sea regions.

Opis:
Ship engines emit noxious gases (SO2, NOx, and VOC) and particulate matter (PM), mostly black carbon. Since 1990, the International Maritime Organization (IMO) regulations gradually restricted the level of emission of NOx, which since 2016 have to be lower than 2-3.4 g/kWh, depending on engine power. SO2 emission reduction has begun since 2010 and now the content of sulphur in marine fuels is limited to 3.5%. At the same time, the Sulphur Emission Control Areas (SECA) has been established, at which the sulphur content in fuel cannot be higher than 0.1%. Since 2020, only a fuel of 0.5% sulphur can be used at all cruising areas outside SECA. It should be noted that due to lack of efficient technology, IMO still has not issued regulations regarding the PM emission by ships. The paper discusses various electrostatic techniques used for the reduction of PM emission in Diesel engine exhausts. Electrostatic scrubber systems, using seawater, allow removal of PM from exhausts with high efficiency and simultaneously SO2 gas. Electrostatic agglomerators allow increasing submicron and nanoparticles by coagulation of those particles to the larger ones, which could be removed by conventional techniques.

The paper introduces the process of safe ship control in collision situations using a differential game model with m participants. The basic model of process includes non-linear state equations and non-linear, time-varying constraints of the state variables as well as the quality game control index in the forms of game integral payment and final payment. As an approximated model of the manoeuvring process, a model of a multi-step matrix game in the form of a dual linear programming problem has been adopted here. The Game Control (gc) computer program has been designed in Matlab/Simulink software in order to determine the own ship safe trajectory. The considerations have been illustrated with computer simulation examples using the gc program for determining safe own ship trajectory in real navigation situations when passing commonly-encountered ships.

This paper describes an application of the dynamic programming method to determine the safety of one’s own ship trajectory during encounter of other ships. A dynamic model of the process, with kinematic constraints of state and determined by a three-layer artificial neural network has been used for the development of control procedures. Non-linear activation functions in the first and second layers may be characterised by a tangent curve while the output layer is of a sigmoidal nature. The Neural Network Toolbox of the Matlab software has been used to model the network. The learning process used an algorithm of backward propagation of the error with an adaptively selected learning step. The considerations have been illustrated through an example implemented in a computer simulation using the algorithm for the determination of the safe ship trajectory in situations of encounter of multiple ships, recorded on the ship’s radar screen in real navigational situation in the Kattegat Strait.

Opis:
World transport faces a serious challenge, which involves the detrimental impact of its activity on the environment. Marine transport is a significant link in the worldwide transport system, which provides the free flow of diversified cargoes and offers competitive prices compared to other modes of transport for the carriage of goods. Seaports enabling waterborne transport have a major impact on the economic, social and natural environment. Port managing authorities show growing awareness of the negative influence of port units on the surrounding environment. Concurrently, environmentally friendly measures are implemented in line with the principles of sustainable development. The article aim is to present the characteristics of the green ports concept in response to ports struggle with environmental problems.

Opis:
In recent years, oil spill accidents have become increasingly frequent due to the development of marine transportation and massive oil exploitation. At present, satellite remote sensing is the principal method used to monitor oil spills. Extracting the locations and extent of oil spill spots accurately in remote sensing images reaps significant benefits in terms of risk assessment and clean-up work. Nowadays the method of edge detection combined with threshold segmenta- tion (EDCTS) to extract oil information is becoming increasingly popular. However, the current method has some limitations in terms of accurately extracting oil spills in synthetic aperture radar (SAR) images, where heterogeneous background noise exists. In this study, we propose an adaptive mechanism based on Otsu method, which applies region growing combined with both edge detection and threshold segmentation (RGEDOM) to extract oil spills. Remote sensing images from the Bohai Sea on June 11, 2011 and the Gulf of Dalian on July 17, 2010 are utilized to validate the accuracy of our algorithm and the reliability of extraction results. In addition, results according to EDCTS are used as a comparator to further explore validity. The comparison with results according to EDCTS using the same dataset demonstrates that the proposed self-adapting algorithm is more robust and boasts high-accuracy. The accuracy computing by the adaptive algorithm is significantly improved compared with EDCTS and threshold method.

Opis:
The paper presents the European Union’s approach to promote the advantages of short sea shipping as efficient and sustainable alternative solution to the global issues of road congestion. European Commission has made Short Sea Shipping one of the major priorities for European transport and maritime industries have made it one of their key areas for development. Short Sea Shipping plays an important role in reaching the objectives of the European Transport Policy, as it can help curb the forecasted substantial increase in heavy goods vehicle traffic, rebalance the modal shares and bypass land bottlenecks. In the paper are presented the advantages of Short Sea Shipping and the measures adopted by the European Union in order to better promote the use of this mode. Short Sea Shipping needs to be developed within an integrated and participatory approach, with the reliable involvement of stakeholders from the entire sector in order to fulfil its economic, commercial, social and environmental role.
