Summary:
With the presence of more and more pipelines and cables in the coastal waters, the need to determine the exact location increases. This extended abstract will focus on sub-bottom detections of cables and pipelines using single channel shallow seismic data and describes the automated contact detection of SILAS. Vital information with regards to cables is the depth of burial of cables and pipelines. A changing bathymetry can create free span of cables, which could lead to potential dangers of an interrupted power or communication grid. If the location and depth is known, risks can be mitigated before mayor problems arise. Methods using an active signal on pipeline or the cable may detect this properly, but result in a shutdown of the cable for the time of monitoring. A passive method to detect these cables and pipelines is sub bottom profiling and will be discussed in this extended abstract.
