Opis:
The section of the paper on simulation studies presents the application of fractional calculus to describe the dynamics of pneumatic systems. In the construction of mathematical models of the analysed dynamic systems, the Riemann-Liouville definition of differ-integral of non-integer order was used. For the analysed model, transfer function of integer and non-integer order was determined. Functions describing characteristics in time and frequency domains were determined, whereas the characteristics of the analysed systems were obtained by means of computer simulation. MATLAB were used for the simulation research. The section of the paper on laboratory research presents the results of the laboratory tests of the injection system of the internal combustion engine with special attention to the verification of simulated tests of selected pneumatic systems described with the use of fractional calculus.

Opis:
It is well known that Weather Routing is one of the effective ship operation methods to reduce fuel consumption and many studies have been conducted to develop the effective calculation methods. However, most studies were performed focusing on the ocean going ships, and there were few studies made for coastal ships. The authors propose a minimum fuel route calculation method for coastal ships that use the precise forecasted environmental data and the propulsion performance data of the ship on actual seas. In the proposed method, we use the Dijkstra’s algorithm to calculate an optimum minimum fuel route suitable for coastal ships. Simulation study was carried out to evaluate the effectiveness of the proposed method using two coastal ships. As the result of study, the authors confirmed that the proposed calculation method is effective for fuel consumption reduction and is applicable for the operation of coastal merchant ships.

Opis:
Power from renewable sources would play a key role in the future of electricity .The wind energy is one of the goal of EU's commitment, which want to develop offshore wind potential [1], [2]. Lubrication of wind turbines is very important for maintenance [3] . The purpose of this paper is to present some considerations about monitoring oiling system. This system monitors kinematic data in real time. The importance of monitoring real data with this system help us to simulate lubrication for various types of wind turbine reducers in order to choose the optimal form of the lubrication system and for good maintenance.

Opis:
A smart solution for assessing the consequences of pollution on the coast, on flora and fauna but also by accounting for the total costs of the equipment used in the response to pollution is a system for assessing, coordinating and simulating the risk situation with the help of a mathematical model implemented on a simulator. The mathematical model for the simulation of the event of pollution is the latest generation and take into account all the meteorological factors of the sea and air, as well as all the physico-chemical parameters of the substances involved (dispersion, surface tension). The simulator is used for the realistic modeling of a crisis situation and it is useful for both marine officers and emergency situation officials. The simulator will be used as an educational instrument enabling the interactive study of the different emergency situations. In this paper we present the simulation of incident and the creation of response resources. The scenario incident is for KAPTAN M cruise ship that left the tourist port of TOMIS Constanta, Romania, having on board 20 passengers and a number of 15 crew members, and which collided with the oil ship EVIA Oil FIVE, having on board the quantity of 4200 MT crude oil. As a result of the collision, the passenger ship suffered a breach (water hole), on the starboard board, breach by which the ship began to ambarce sea water and in the car compartment a fire was produced. Containment and recovery of an oil spill during the exercise will be simulated through activation and control of response resources. The resources involved in the operations are divided into: platforms, equipment and personnel. The results of simulation is the list of response resources specified in the scenario together with their parameters, which can be exported into a text file. With this simulation tools you can efficiently appreciate the cost of resources in due time, avoiding material and human damage.

Opis:
The increasing sizes of ships and lack of functionality of the existing solutions determine the interest in rebuilding the already existing solutions. Simulation models allow to analyse the possible modernisation variants taking into account the variability of elementary parameters. The article presents analysis results for the Przemyslowy Canal in Szczecin with respect to navigation safety and regulating traffic regulations in the Przemyslowy Canal taking into consideration the interests of all subjects involved. The paper applies real-time simulation methods based on manoeuvring simulators. After a thorough analysis that took into account the safety of navigation, further possibilities of development have been determined. Study results are aimed at designing new solutions in case of modernization of the Przemyslowy Canal in Szczecin.

Opis:
Real time ship manoeuvring simulations are a valuable source of information in the detailed design phase of nautical studies. The feedback of pilots, which is not available for fast time simulations that are carried out by a computerized autopilot, is an important asset in the evaluation of the feasibility of ship manoeuvres. However, real time simulations are significantly more expensive in that realistic 3D visuals are needed so that the pilot can immerse himself in a sailing environment. Modelling and generating such 3D views is time consuming and requires expensive hardware and special skills. Real time simulations that offer only a 2D bird’s eye view for the execution of manoeuvres by pilots, can sometimes be used as a cheaper and faster alternative. This paper presents a case study that evaluates the nautical access to two harbours and discusses some of the advantages and disadvantages of a real time bird’s eye view setup.

Forces Exerted on Ships
Opis:
Ship maneuvering in restricted waters of harbor basins and navigation channels had been the main concern in recent years due to sudden increase of ship’s size. When the ship enters a navigation channel the lateral boundary of the channel exerts a transverse force and turning moment on the ship hull. These forces are so important in the analysis of safety of ship navigation in the channels. Ship model test in the towing tank is a reliable method to evaluate these forces. Therefore systematic model tests are held for modeling of the forces exerted on the tanker ship and dhow model traveling alongside a vertical wall. A database of the interaction forces is developed and the specific hydrodynamic effects related to the phenomena are discussed. The results can be used for simulation of ship maneuvering and assessment of safety limits for navigation of ships alongside the quay walls and breakwaters.

Reconstructing a Marine Casualty: The Effectiveness of the Full-Mission Simulator as a Casualty Analysis Tool

Opis:
The primary purpose of a marine casualty investigation is to seek to establish the causal factors of the casualty with a view to learning the hard lessons and avoiding a repetition. The broad questions of an investigation: ""who?, what?, when?, where?, why?, and how?"", all help to uncover the facts. The investigation sequence will cover a diverse range of fact-finding activities, amongst which, as often the case, may be a requirement for “conducting specialised studies”. Following the fact-finding stage the typical investigation progresses to analysis of the facts, reaches conclusions and makes recommendations. Keeping an open mind, to avoid premature conclusions, requires the separation of the fact-finding and analysis phases. But the analysis may well help to identify missing pieces of evidence, or different lines of enquiry that may otherwise have gone undetected. As an effective reconstruction tool, a full-mission bridge simulator offers an opportunity to examine a broad spectrum of environmental conditions and vessel characteristics, as well as equipment failures, human factors and operating procedures. A casualty incident can be reconstructed in a real-time simulated environment, to aid more detailed analysis. Within the usual confines of the legal process, comprehension of nautical ‘black magic’ is greatly simplified for non-mariners, by seeing the simulated casualty incident unfold, in real-time or in selected short-time segments.
