Sonsub Survey BP Azerbaijan DWG East Manifold Six Shooter Bathymetry Survey

PatchTestSub-contracted through NetSurvey to provide Sonsub Survey with specialist multibeam personnel onboard the MV Citadel for the BP Azerbaijan DWG East Manifold Six Shooter Bathymetry Survey project. The scope of work consisted of a detailed high-resolution bathymetry survey, required to identify any seabed features, such as obstacles or debris, prior to the installation of the Six Shooter drilling rig and subsequent development activities. A work-class Innovator ROV was fitted with a Reson 7125-ROV2 multibeam system, together with a Doppler Velocity Log for integration into the vessel’s USBL system. Working water depths were in excess of 200m, with a requirement for 20cm resolution DTMs, delivered together with snippets backscatter mosaics. The QINSy software package was used for initial data acquisition and processing, with the Fledermaus suite used for cleaning, surface generation, and visualization. ArcGIS was utilised for generating final deliverables, which had to be compliant with BP’s SSDM GIS Geodatabase.
