SCHOTTEL HYDRO has developed the SCHOTTEL Instream Turbine (SIT). Four SITs had been mounted on Sustainable Marine Energy’s floating surface platform PLAT-I, with a combined platform rated power of 280kW. The PLAT-I platform has been undergoing field performance testing in Scotland to determine the power performance of the individual turbines according to IEC62600- 200.
Time series as well as processed performance data shows a high spatial variation of the inflow across the platform and hence a high dependency on the flow speed measurement location. The turbines power performance is found to be in line with design predictions, whereas the thrust loads measured are lower than the predictions.
