Processing of the Data Obtained with the Advanced Doppler Velocymeter

Abstract:

We present data obtained after a 2 years period of monitoring the wave’s parameters in an off-shore location. We have used the location of a working petroleum platform situated at: N44⁰31’, E29⁰34’ at 50 km from land and 80 km NE from Constanta Harbor, in the Romanian Black Sea waters. We describe monitoring systems used.and their solution. The Advanced Doppler Velocymeter (ADV) for parameters of marine waves is based on Doppler effect and it is composed of a transmitter at a frequency of 10 MHz and of 3 receivers which are equidistant from 1200. Data storage on the HDD PC, with the possibility of take-over and normal review (ASCII file). We can get the values of the speed and current division marine tide amplitude and direction of the wave at each measurement, the number of measurements, date, hour, minute and second of measurement, as well as other parameters, both as numeric values and a graph having abscissa registration number. This monitoring, which comprises the period of one year including, reveals an amplitude an annual average of the wave of h_med=1.53 m, obtained by taking maximum envelope appeared in a measurement range of 120 seconds. We compare these off-shore values with the coastal ones and we conclude that the wave’s energetic off-shore potential is unexpectedly bigger that in the coastal region.
