SERG-Tidal is a tidal turbine prediction program developed at the University of Southampton is based on a blade element momentum (BEM) program for wind turbines initially developed in the late 1980’s at the university by Barnsley & Wellicome.
The new code developed has major enhancements specifically established to deal with the operation in water and other additions including improved interpolation, extrapolation for stall data and options for tip loss factor. The programme is modular and designed to allow blade optimisation studies to be performed. Full details of the program are given in a technical report and results discussed in the following paper:

The experimental validation data have also been used in collaboration with Garrad Hassan who are developing a tidal version of there popular commercial software GH-Bladed for analysis of wind turbines. The results from both our and Garrad Hassan’s simulations have been compared in:
