We offer surveys involving geotechnical data acquisition, environmental data acquisition, data processing, Suitable designed Seabed mapping system Charting and reporting.
Bathymetric Data Acquisition
Quasar Subsea has a long track record of collecting bathymetric data, using the latest Multi-Beam Echo Sounders (MBES), whether it be ROV-based or over-the-side pole-based systems. Offshore applications such as trenching (pre-cut, pre-lay, post-lay and intermediate surveys), dredging (pre, post and real-time surveys), sonar/acoustic pipeline inspection, site surveys, or any requirement for a map of the seabed, can be supported with a suitably designed mapping system.
Geotechnical Data Investigation
We offer ground truthing of geophysical data in the form of Cone Penetration Testing (CPT), Vibrocore, Gravity/Piston core, box core and grab sampling. Geotechnical acquisition is offered as an integrated or independent service to suit our clients’ needs.
Environmental Data Acquisition
Environmental data acquisition services comprise; stills camera / video and seabed sampling to meet our client’s environmental baseline and habitat assessment requirements.
Data Processing, Charting and Reporting
Supporting all elements of data acquisition both during seabed mapping and route surveys, we offer data processing, charting and reporting of the acquired data. We provide clients with the tools and personnel needed to perform data processing, either onboard the vessel or using the Quasar office facilities.
We use the Eiva NaviSuite, Sonarwiz, Qinsy QPS, and Qimera together with supplementary tools such as ArcGIS, QGIS and CAD-based charting, all to industry standards. We can provide USBL and DVL positioning post-processing, powerful INS post-processing and automated multi-beam echo sounder data cleaning, all tools which increase the quality of data and increase efficiency to save valuable time.
