高价值资产（即船舶、海上平台、加工工业中的管道）上的污垢形成是一个严重的问题，会对环境和结构的操作造成破坏。工业中常见的结垢机理是水垢的存款、海洋生物的沉降和生长。这是评估这些资产的使用寿命和安全性的一个重要因素。大量的资金用于移除和预防方法，以保持资产的有效运行。这些方法中的大多数是有毒的，并且与这些技术相关的环境问题已经导致对去除污垢的替代方法的研究。提出了一种利用大功率超声波进行非侵入式除垢的方法。声空化现象与污垢去除过程中结构发生的离面位移有关。这是一种节省成本和时间的方法，更重要的是，这是一种环境可持续的污垢去除方法。此外，本文介绍了在布鲁内尔创新中心在这一领域进行的研究。通过合作研究项目，该技术已开发用于各种工业应用的不同污垢类型。已经建立了一种方法来选择传感器和硬件。实验和仿真结果证明了该技术的有效性。
Fouling formation on high value assets i.e. ships, offshore platforms, pipelines in the processing industry is a significant problem causing destruction to the environment and operations of the structure. Common fouling mechanisms in industry are deposit of scales, settlement and growth of marine organisms. It is an important factor, in order to assess the service lifetime and safety of these assets. Large sums of money are spent for removal and preventative methods to maintain efficient operation of the asset. Most of these methods are toxic and the environmental concerns associated with these techniques has led to studies on alternative methods to remove fouling. This paper proposes a non-invasive method of removing fouling using high power ultrasound. The acoustic cavitation phenomenon is related with the out-of-the-plane displacement occurring in structures for the fouling removal process. This is a cost and time effective method and more importantly, an environmentally sustainable method of fouling removal. Furthermore, this paper presents the research carried out at the Brunel Innovation Centre in this field. Through collaborative research projects, this technology has been developed for different fouling types specific to various industrial applications. A methodology has been established for the selection of the transducers and the hardware. The techniques effectiveness has been proven through experimental and simulation results.
