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.
