    Design and analysis tools for offshore wind turbines

    We have put a significant amount of effort into developing our competence and ability to model and analyse offshore wind turbines. One important activity is the development and improvement of design and analysis tools for bottom mounted (piled) and floating wind turbines. These include NIRWANA for bottom-mounted offshore wind turbines and SIMO/RIFLEX for floating turbines.

    Loading and flow investigation of tidal turbine

    Tidal Generation Limited (TGL) a wholly owned subsidiary of Rolls-Royce Plc has developed a tidal turbine and associated installation, deployment and maintenance methodologies. The turbine power-train comprises an axial flow, variable pitch, variable speed, three bladed rotor coupled to a gearbox and induction generator.

  • Testing tidal turbines in extreme combinations of waves and currents

    Testing tidal turbines in extreme combinations of waves and currents

    Tidal turbines operate in demanding environments, with wide variations in current speed and direction. These environmental conditions have led to structural weaknesses and failures in several tidal turbine installations. Knowledge of dynamic loads and insight into the hydrodynamic functioning of turbines are decisive factors affecting stable, long-term operation.

    Numerical model tools for floating wind turbines

    MARINTEK has been working for many years on long-term offshore wind-power research projects. As part of NOWITECH’s research programme, we have developed a design software package (WINDOPT) for the optimisation of SPAR-type floating wind-turbines. This tool is used to optimise the design of SPAR buoys and their mooring systems.
