“…In the frequency range (0-200 Hz) of the spectrum in the healthy machine ( Figure 5(a)), one can see that the frequency components at show that a great number of eccentricity harmonics appeared in Figure 5(b). The magnitudes of eccentricity harmonics are also increased and the frequency component at 3 1 + can also be observed with the faulty bearing due to the fault-related eccentricity according to (18) and (19) (with = of = 0). The fault characteristic frequency at 1 + is visible and the other fault-related component at 1 + + can also be noticed in the faulty spectrum ( Figure 5(b)).…”

“…When a localized defective bearing runs at a constant speed, a periodic impact between rolling elements and the raceway is produced [6,13]. The existence of such impulsive forces gives rise to an increase in the vibration level [18,19]. The characteristic frequencies of these vibrations rely on fault location, bearing geometry, and operating speed [20,21].…”

Bearing faults are the most frequent faults of induction motors. The current spectrum analysis is an easy and popular method for the monitoring and detection of bearing faults. After a presentation of the existing fault models, this paper illustrates an analytical approach to evaluate the effects of the slot harmonics on the stator current in an induction motor with bearing fault. Simple and clear theoretical analysis results in some new current characteristic frequencies. Experimental tests with artificial bearing outer raceway fault are carried out by measuring stator current signals. The experimental results by spectral analysis of the stator current agree well with the theoretical inference.

“…Regardless of the chosen generator type, all subassemblies in the generator setup are expected to remain in their normal working conditions with their components monitored, where necessary. For the shaft and gearbox, vibrations and temperatures are important parameters to monitor [14]. However, for some marine energy generation systems, which are submerged into the sea, temperatures are almost always fixed by the cooling surrounding seawater and hence cannot be used as a sole feature for determining their working conditions.…”

E nergy is very important to the world as a driver of the modern society. According to estimations done by the International Energy Agency (IEA), the total global energy consumption is about 17 500 TW·h/yr [1]. In the past, fossil fuels like coal, oil and natural gas supplied the biggest part of this global consumption, and they were far larger than those of the renewable energy sources as Fig. 1 shows for 1973 [2]. In 2011, the production of renewable energy and global energy consumption increased, even though renewable energy was still much smaller than fossil fuels as Fig. 1 shows. [2].There are several sources of renewable energy such as hydro, wind, solar, biofuel, and marine energy. However, since 71% of the earth's surface is covered by sea, marine energy is a meaningful resource for consideration, especially when faced with an ever-growing energy demand. Marine energy includes: offshore wind energy, wave, tidal, tidal current, thermal, and salinity gradient energy. Fig. 2 is an illustration of the potential of the six marine energy types [3]. The total marine energy that could be harnessed is estimated at around 100 000 TW·h/yr [1], [3] which far exceeds all of the present human needs around the world. This makes it important to understand the marine energy generation systems and the monitoring and control issues, which are discussed in this article. Marine Energy Systems OverviewMarine energy generation systems differ primarily in the ways the energy is captured and then converted into electrical energy. Most other building blocks in the generation systems remain nearly the same after being transformed into the electrical form. Hence, attention should be directed at the mechanisms needed for converting marine energy into electrical energy. The different technologies are discussed as follows. Offshore Wind EnergyOffshore wind turbines are either fixed to the sea or float at the surface. Fixed wind turbines are anchored to the seabed to improve structural stability. However, they are difficult to operate as the increase of the distance from the shore where the wind is more abundant. Therefore, floating wind turbines mounted on pontoons have been developed. The pontoons must be attached to the sea bed by long steel cables. This floating wind turbine technology is still undergoing tests to determine its practicality as the systems are typically located in deep water. Beside their anchoring differences, both types of offshore wind generation systems share the same operating principle, the turbine blades are rotated by the wind. Energy from the blades is then passed along the rotating axis Fig. 1. Distribution of global energy supplies in 1973 and 2011 [2]. Fig. 2. Relative potentials of different marine energy sources.

Expanded ship automatization levels prompt better usefulness and security, and also decreased expenses and team numbers. Incorporated into the introduction is as of late authorized impetus observing framework for quick watch vessels, dispersed fire and flooding assurance framework, send direction arrangement of a profound flexibility little vessel, maritime programmed degaussing structures, coordinated minimal effort mine countermeasures framework and organized hydrographic study and route framework for inland conduits. Vitality is essential to the world as a driver of the present day society. As per estimations were done by the International Energy Agency (IEA), the aggregate worldwide vitality utilization is around 17500 TW h/yr. Before petroleum derivatives like coal, oil and flammable gas provided the most significant piece of this global usage, and they were far more significant than those of the sustainable power sources. In 2011, the creation of viable power source and worldwide vitality utilization expanded, despite the fact that sustainable power source was still substantially littler than petroleum derivatives. There are a few wellsprings of a viable power source, for example, hydro, wind, sunlight based, biofuel, and marine vitality. Be that as it may, since 71% of the world's surface is secured via ocean, marine vitality is a significant asset for thought, particularly when confronted with a perpetually developing vitality request. Aquatic dynamism incorporates seaward wind vitality, wave, tidal, tidal ebb and flows, warm, and saltiness slope vitality.
