ScottishPower Renewables is looking for a low cost, standalone, battery powered vibration monitoring and logging device for offshore wind turbine sub-structures, covering the period between foundation installation and full turbine commissioning. Selected solution provider(s) may have the opportunity to present their solution to ScottishPower Renewables. It is also possible that further activities may be undertaken, such as a benchmarking trial on an operational wind farm alongside existing, permanent structural monitoring instrumentation, with the potential for volume deployment across the ScottishPower Renewables construction pipeline and reuse across successive projects. This is not guaranteed and will be solely at the discretion of ScottishPower Renewables.
