ATTACH – Acoustic Tagging Technologies Applied to Cables and subsea Hardware

ATTACH（应用于电缆和海底硬件的声学标记技术）项目是海底资产定位技术（SALT）有限公司，Precision Acoustics Ltd.和伯明翰大学进行可行性研究，以确定标记电缆和管道等高价值海底能源资产的遥感声学方法。人们通常不理解，寻找资产可能需要大量的时间和金钱，因为电缆或管道可能由于洋流而被掩埋或移动，该资产然后可以变得对声纳系统不可见。因此，任何追踪资产而不必挖掘的方法都将大大降低成本。该项目的目的是设计漂浮在资产上方的合成声纳目标，并且使用声纳系统比资产本身更容易检测。人们可以想象，如果能够在几百米的范围内看到一串这样的目标（就像夜间开车时的猫眼），将大大提高这类资产的可探测性。

The ATTACH (Acoustic Tagging Technologies Applied to Cables and subsea Hardware) project is a three-waycollaboration between Subsea Asset Location Technologies (SALT) Ltd., Precision Acoustics Ltd. and theUniversity of Birmingham to carry out a feasibility study to identify remote-sensing, acoustical methods oflabelling high-value subsea energy assets, such as cables and pipelines.It is not generally appreciated that finding an asset might take a significant amount of time and money as thecable, or pipeline, might have been buried or moved as a result of ocean currents, the asset may then becomeinvisible to a sonar system. Thus any method of tracking the asset without having to excavate it woulddramatically reduce costs. The aim of this project is to design synthetic sonar targets that float above the assetand are significantly easier to detect using a sonar system then the asset itself. One can imagine that beingable to see a string of such targets over a range of a few hundreds of metres (likened to cat’s-eyes whilstdriving at night) would dramatically increase the detectability of such assets.
