## Measurement system
The measurement system installed at blyth comprises three main elements: (i) measurement of the turbine structural loading (not public available) , (ii) measurement of the sea-state, and (iii) measurement of wind conditions at an onshore meteorological mast close to the turbine. The instrumentation comprising each of these sub-systems is described briefly below. Sea state climate: The wave and current climate is recorded using instruments mounted both above and below water level. A Saab WaveRadar unit is mounted on the turbine walkway to measure the instantaneous water level at the turbine base, including time-history profiles of passing waves. Simultaneously, instruments mounted on the sea bed approximately 40m from the foundation record statistics describing the wave climate and the current profile. These instruments include a wave and tide recorder (Coastal Leasing Microspec) and an acoustic doppler current profiler (Nortek ADCP). Wind measurements: Wind conditions are measured using anemometers and wind vanes mounted on an onshore meteorological mast and on the turbine nacelle. Although the meteorological mast for the project would be ideally located offshore, close to the monitored turbine, the large cost of such an installation was beyond the budget of the OWTES project. The mast has therefore been positioned on the coast, approximately 1km from the southern turbine. The mast features anemometers at heights of 10m, 20m, 30m and 40m above ground level and instruments to measure atmospheric pressure, temperature and precipitation. Measurement programme: The turbine structural loads, the sea-state at the turbine base and the wind characteristics are recorded simultaneously using a Garrad Hassan T-MON measurement system. This well-proven, robust system is well suited to offshore applications. Analogue-to-digital converters are distributed around the turbine structure and send data via a fibre-optic link to an onshore control room. Here, the collection and recording of data is controlled by a central computer which has a modem connection to allow remote interrogation. The measurement period began in November 2001 and will continue to November 2002. During this period, every sensor on the turbine is being sampled at 20Hz and data collected in two formats: ‘summary’ datasets and ‘campaign’ datasets. Summary datasets consist of the basic statistics of each channel, measured every ten minutes, comprising the minimum, maximum, mean and standard deviation of each signal. Campaign datasets store time-history data from each measured channel and will be recorded in order to establish the dynamic behaviour, fatigue load spectra and extreme loads experienced by the turbine. The recording of campaign datasets is triggered automatically by the central computer when pre-defined trigger conditions are met. A database of campaign datasets is currently being compiled for a range of ‘normal’ conditions, covering variations in mean water level, mean wind speed and significant wave height. Campaign datasets are also being used to record extreme wave loading events. Summary datasets are being used for a number of purposes, one of which is to compile a database of wind and wave characteristics at the site.
