Analiza technologii on-shore power supply

OnShore Power Supply (OPS), czyli tzw. „zasilanie lądowe”, umożliwia statkom otrzymywanie energii elektrycznej z lokalnej sieci. Korzystając z tej alternatywy, zanieczyszczenie środowiska jest zmniejszone, ponieważ pokładowy generator diesla może zostać wyłączony. Technologia ta, jest wykorzystywana od wielu lat, lecz dopiero teraz zdobywa uznanie. W artykule dokonano analizy OPS. W części teoretycznej przedstawiono czym jest ta technologia i jaka jest budowa urządzeń zasilania lądowego. W części badawczej wykorzystano studium przypadku oraz analizę SWOT, która pozwoliła na wyróżnienie mocnych i słabych stron opisywanej technologii.

OnShore Power Supply (OPS), i.e. "shore power" enables ships to receive electricity from the local grid. By using this alternative, pollution is reduced as the on-board diesel generator can be turned off. This technology has been used for many years, but is only now gaining recognition. The article analyzes OPS. The theoretical part presents what this technology is and what is the construction of shore power devices. In the research part, a case study and SWOT analysis were used, which allowed to distinguish the strengths and weaknesses of the described technology.

The investment policy applied by seaport authorities has a great impact on the state of the natural environment in coastal regions. Unfortunately, in many cases, their environmental efforts are limited to the issues which are defined by the applicable legal regulations determined by International Maritime Organization, the Organization of United Nations and the European Commission etc. However, in recent years we can observe significant improvement in this area, especially in the seaports of Northern Europe. They often decide on highly capital-intensive pro-ecological investments allowing to reduce the level of pollution emitted from cruise ships during their handling in ports, such as e. g. the opportunity of connecting vessels to the shore-side energy supply systems. Various solutions in this area are currently used in the world. The ports in Northern Europe are currently the leaders in this area. The use of such solutions is cost-intensive, but it significantly reduces the level of pollution emitted by ships into the environment, and the level of noise and vibration caused by engines. This paper aims to assess the seaports' involvement in Northern Europe in the preparation of seaport infrastructure enabling cruise ships to be connected to the onshore power supply systems. The article contains the results of surveys conducted with the use of two methods to adjust the research technique to the respondents’ needs, i.e. CASI (Computer-Assisted Self Interviewing) and EMS (Electronic Mail Survey). The empirical research was conducted among the seaports in Northern Europe. The results of the survey may be of interest to seaport authorities and cruise ship owners.
