Page 22-25: Traditional solutions for generating electricity from the tides, where tidal turbines are installed on the seabed, require high-end offshore installation vessels and do not allow for easy access for maintenance. The BlueTEC's platform has a different approach. It is a permanently moored platform which generates renewable electricity from tidal currents by holding a tidal turbine underneath!
Page 14-17: Renewable energy is ‘hot’ these days. Marine energy can manifest itself in more shapes, including tidal and wave energy. These are more specific to a location but their potential can be surprising. The European Marine Energy Centre (EMEC) in the UK is a test centre for tidal and wave energy devices operating in an interesting area with wave and tidal potential. Hydro International interviews Mr Neil Kermode, managing director of EMEC.
Page 31-33: Inertial Navigation Systems (INSs) are a great help in applications where either position stability is of great importance or where bridging (small) positioning gaps is a requirement. To understand INS imagine you are standing blindfolded in the centre of a long hallway. Start walking, you may proceed quickly at first, covering ground with confidence. Eventually, however, you begin to lose your sense of alignment. This ability to successfully navigate when denied a visual frame of reference, represents our own basic human form of inertial navigation.
Page 18-21: The rapid growth of interest in tidal energy has highlighted the role of current profilers, able to measure the speed and direction of currents with increased accuracy in some of the harshest marine environments in the world. While the turbines produce the power, current profiling technology plays an important role in maximising the efficiency of this promising area of renewable energy.
