Object detection Cables, pipelines and boulders Deliverables • Depth of burial surveys • Cable and pipeline mapping • Location of objects within the sea bed A combination of the Stema EBP system and the Silas Software Suite enables the user to perform high resolution object detection surveys. The Silas Object detection module then allows an automated contact recognition, identifying objects such as cables, pipelines and boulders. These objects can be detected with a success rate of 75% and higher both for objects and cables. The contact recognition consists of the automated determination of two quantifi able parameters which enable a more objective classifi cation of detected contacts. Besides the object contacts themselves, the sub-bottom data also shows the sub-bottom structures, including the cable trenches. The latest development of the Silas Software Suite provides the possibility to import multiple data sets for cross correlation and mapping of the objects in X, Y and Z coordinates. Example of Silas sections with detected cable (left) and detected pipelines (right). Topview of detected pipeline with multibeam overlay and cross-section of the same pipeline which clearly depicts depth of burial. Key features • Automated contact detection • Correlation with other data (MB, SSS, Magneto) • More objective classifi cation of detected contacts Cross-section of typical export cable, which can be detected sub-bottom with Silas cable detection.
