WINSPEC will study the feasibility and specification of a marine operated, low frequency modulated ultrasonic 'pulse-echo' method for monitoring the structure and condition of the layered foundations of offshore wind turbines. Numerical modelling and some laboratory testing will be undertaken to evaluate the sensitivity and characteristics of the spectral response to differing layered model representations of the foundation structure with various condition 'defects' built in. This work will provide experimental and modeled analyses to support a feasibility assessment of the 'pulse-echo' approach, where possible, identifying characteristic acoustic patterns (or signatures) that relate to varying the material properties of the layers and structure of the layered sequence, such as thickness and density and the introduction of inter-layer water. This work will be supported by E.ON Technologies (Ratcliffe) Ltd. who are responsible the maintenance of many of the UK's offshore wind farms such as Robin Rigg in the Solway Firth. These wind farms are national assets; for example Robin Rigg provides 180 MW of power to the National Grid (enough energy for over 100, 000 households). This method could form the basis for a safe, low power technology for deployment on underwater unmanned vehicles for inspecting the inner structure and condition of offshore wind turbine foundations. In so doing, WINSPEC would stimulate a shift towards improved asset inspection technologies supporting preventative interventions maintaining wind farm operation at higher generating capacities.

WINSPEC将研究海上操作、低频调制的超声波“脉冲回波”方法的可行性和规格，以监测海上风力涡轮机层状地基的结构和状况。将进行数值模拟和一些实验室测试，以评估不同分层模型表示的具有不同条件的缺陷的基础结构的光谱响应的敏感性和特性。这项工作将提供实验和模拟分析，以支持“脉冲-回波”方法的可行性评估，在可能的情况下，确定与改变地层的材料属性和分层层序的结构有关的特征声学模式(或特征)，如厚度和密度以及层间水的引入。这项工作将由E.ON Technologies(Ratcliffe)Ltd.提供支持，该公司负责英国许多海上风力发电场的维护，例如Solway Firth的Robin Rigg。这些风电场是国家资产；例如，Robin Rigg为国家电网提供180兆瓦的电力(足够100,000多户家庭使用)。该方法为水下无人潜水器检测海上风力机基础内部结构和状态的安全、低功耗技术奠定了基础。通过这样做，WINSPEC将刺激向改进的资产检查技术的转变，以支持预防性干预，保持风力发电场在更高发电能力下的运营。
