Opis:
Wind energy is one of the most environmentally friendly energy industries. Wind power is used in more than 70 countries of the world to produce electricity. Wind power plants generate more than 1% of the world’s electricity. Wind energy is considered to be one of the most popular renewable energy sources. In countries where this energy is already widely used, the environmental conditions substantially improve. To increase the efficiency of wind power plants and work reliability, and also to solve other problems, it is necessary to carry out climate research on wind energy and collect information on the distribution of wind energy depending on wind speed profiles, etc.

Opis:
Wind is such an element of sea environment, from which it is relatively easy to obtain energy. Wind parameters over both seas and oceans are more favorable than those on land (due to variability of landform features). Moreover, also sea wind turbines exercise comparatively smaller negative effect on people than on land. Therefore, sea wind farms are ahead of us, as further development of wind energy. The article presents basic parameters of wind turbines, possible installations on sea bed, as well as future designs of large floating sea farms. The article presents also an example of design analyses of wind turbine, using computational fluid dynamics (CFD).

Opis:
Almost every voyage culminates in a manoeuvre to berth the ship safely along a quay or wharf. During this phase a ship is affected by a number of factors, one of them being wind. This paper seeks to understand how wind affect a ship in regards of power consumption during berthing. A field study was conducted on a car passenger ferry, where every approach in one harbour was logged and analysed over a period of four months. The goal was to provide greater knowledge about energy usage and the study presents several interesting findings. It is estimated that power consumption is stable when the median wind speed is less than 4 m/s. Stronger winds have a significant effect on power consumption, e.g 17 m/s gives an 106,31% increase from calm conditions. Furthermore there is not discovered any correlation between consumption and wind direction in this study.

Opis:
W ostatnich latach energetyka wiatrowa jest najszybciej rozwijającą się gałęzią energetyki. Turbiny wiatrowe są źródłami energii o najwyższej dyspozycyjności. Aby utrzymać wysokie wskaźniki dyspozycyjności niezbędne jest stosowanie systemów monitorowania i diagnostyki. Proces ten jest przyspieszany przez aktywną politykę firm ubezpieczeniowych. Artykuł przedstawia system MDS Wind, który jest nowoczesnym systemem monitorowania i diagnostyki turbin wiatrowych. W pierwszej części scharakteryzowano turbinę wiatrową jako obiekt monitorowania. W kolejnej części opisano strukturę systemu MDS Wind, a następnie przedstawiono algorytmy oprogramowania. Przedstawiono przykładowe estymaty sygnałów drganiowych wyznaczonych przez system wraz z przykładami ich zastosowania do monitorowania turbiny wiatrowej. W ostatniej części opisano bogate możliwości interfejsu użytkownika. System MDS Wind uzyskał w czerwcu 2005 certyfikację Allianz Zentrum Fuer Technik.

Opis:
The following paper presents a methodology of wind turbines selection with a axis of rotation based on measurements of wind conditions specific for the wind power sector. Basic properties and characteristics used in the wind power sector, as well as a proper measurement campaign along with determining the necessary instrumentation and the methodology of its use, are the basic parameters that determine the decision of wind farm investment. The main goal of those activities is to gather the accurate meteorological data in sufficient amount using a measurement tower situated at a possible future location of a wind farm. This method is used to identify the direction, speed, gust and energy of the wind. Measurements were made in northern Poland using a measurement system based on a 80-meter-high telescopic mast. The system was equipped with instrumentation necessary to measure and record the basic wind parameters, and was made by the Windhunter Serwis Ltd. Company headquartered in Koszalin. The reliability of measurements was verified using the statistical methods based on the Weitbull’s distribution and the windrose. Thus, the energy potential of the raw air stream was determined with a possible future use in a wind farm sitting.

Opis:
All ships experience an air and wind resistance while under way of sea, and they may experience adverse effects on wind while manoeuvring in harbours and limited waterways. The wind resistance is proportional to relative wind speed squared, wind direction and the projected windage area of the ship. The paper describes the effect of wind pressure into the ship’s superstructures and houses on ship manoeuvrability, in the range of the wind speed, for the ship which is with the large windage area. The above is one of the recommended information to be included in the ship’s manoeuvring booklet, as per IMO Resolution A.601(15). In sea practice, the manoeuvring characteristics in wind, as wind forces and moments, course-keeping limitation, and drifting under wind influence are fare from these estimated. The results obtained during the several years of practice in ship’s exploitation are included in this paper.

Opis:
The average daily values of wind speed and wind gust speed in the years 2001–2018 in Siedlce were analyzed. In the study area, the frequency of individual wind directions was determined and, according to criteria set by the Government Centre for Security, the frequency of hazards from damaging wind gusts was evaluated. The following wind gusts were considered: >20 m/s, 25 m/s and 35 m/s. It was found that, in the Siedlce area, the prevailing wind direction was west-south-westerly (WSW), and the average annual wind speed in the long-term study period was 2.99 m/s. March, April and May were the months when the highest speeds of maximum wind gusts (>35 m/s) were recorded. Extreme wind gusts the speed of which poses a hazard to the environment, national economy as well as human life and health, occurred in both the cold and warm seasons of the year.

Opis:
This article indicates the development trends in the construction of offshore wind turbines worldwide, and the characteristics of existing and planned ships for wind turbine installation and maintenance; it presents an approach to design ports with their future operations in mind. Problem: The safety of navigation in port waterways is the basic restrictions for the construction of harbors (terminals) to handle ships used for the construction of OWT and for increasing their size. Navigational risk is a criterion of navigational safety assessment that allows its accurate estimation in port waterways. Method: The article presents the method for dimensioning port waterways for ships serving offshore sea wind turbine transport and construction. Furthermore, a method for determining the navigational risk of jack-up vessels navigating in port waterway areas is presented. Results: The authors have determined conditions for safe operation of these ships in restricted areas and defined the basic condition of navigational safety. The presented method of navigational risk analysis refers to the departure of a loaded ship carrying offshore wind turbine components in the presently designed port terminal in Świnoujście for handling offshore wind farm projects. Conclusion: These are universal methods that can be applied to the design of ports serving vessels that install offshore wind turbines in various types of waters.
