Opis:
Maritime transportation is the essence of international economy. Today, around ninety percent of world trade happens by maritime transportation via 50,000 merchant ships. These ships transport various types of cargo and manned by over a million mariners around the world. Majority of these ships are propelled by marine diesel engines, hereafter referred to as main engine, due to its reliability and fuel efficiency. Yet numerous accidents take place due to failure of main engine at sea, the main cause of this being inappropriate maintenance plan. To arrive at an optimal maintenance plan, it is necessary to assess the reliability of the main engine. At present the main engine on board vessels have a Planned Maintenance System (PMS), designed by the ship management companies, considering, advise of the engine manufacturers and/or ship’s chief engineers and masters. Following PMS amounts to carrying out maintenance of a main engine components at specified running hours, without taking into consideration the assessment of the health of the component/s in question. Furthermore, shipping companies have a limited technical ability to record the data properly and use them effectively. In this study, relevant data collected from various sources are analysed to identify the most appropriate failure model representing specific component. The data collected, and model developed will be very useful to assess the reliability of the marine engines and to plan the maintenance activities on-board the ship. This could lead to a decrease in the failure of marine engine, ultimately contributing to the reduction of accidents in the shipping industry.

Opis:
Today huge capacity sea-going vessels are propelled by mega high-powered marine diesel engines, referred to as Main Engine. Turbocharging system is an integral part of large marine diesel engine plant, contributing to their safety, reliability, and efficiency. Defects in the turbocharging system could result in higher fuel consumption, erratic running of the Main Engine, and in the worst scenario may result in the stoppage of the Main Engine at sea. An inefficient turbocharging system may also cause major damage to turbochargers, resulting in undesirable accidents out at sea. To avoid such undesirable accidents and ensure smooth operations of the Main Engine, it is required to address this concern. The aim of this research is to study the turbocharging system for a large Main Engine using a Kongsberg engine simulator. Various malfunction of the Turbocharging system is considered, relevant data is collected and analysed. Moreover, a Fault Tree Analysis, (FTA) is considered to identify the top undesirable event which is the failure of the Main Engine. Based on the results of this study, various steps are suggested to avoid failure of the Main Engine due to the defective turbocharging system.

Opis:
This article shows the importance of the diagnostic improvement methods of marine engines to boost the economy and safety of operation of marine cargo ships. The need to implement effective diagnostic methods is justified by presenting statistical data of marine diesel engines failure and the cost of their operation. Based on the own research has been proven, for the chosen example, that indicator diagrams and analysis of indicated parameters have limited utility in the diagnosis of damages of marine engine, although this is a method commonly used in operational practice. To achieve greater diagnostic effectiveness, when, based on indicator diagrams, are calculated and then the characteristics of heat release is analyzed - net of heat release characteristics and the intensity of the heat release, it was demonstrated. This procedure is particularly effective in the diagnosis of damage of injection system components marine diesel engine.

Opis:
The ship technical failures contribution in overall number of navigational accidents are significantly smaller than those caused by human factor but in safety analysis they cannot be neglected. The paper presents methodology of modeling the technical failures of ships with respect of most important ship systems such as main engine, power generators and steering gear. The repair time is also taken into account. The data for simulation was obtained from analysis of ships statistical data of polish owners. The model could be used mostly in assessment with projecting phase of ship appliances, simulating owner’s economical analysis or generating random events in marine simulators.
