Route Surveys

iSURVEY utilise multibeam echosounder (MBE), side scan sonar (SSS) and sub bottom profiler (SBP) systems to carry out route surveys prior to cable and pipeline laying operations, or subsea construction projects.

Side Scan Sonar Data Acquisition


iSURVEY provides services to acquire high quality Side Scan Sonar (SSS) data. SSS data is used to provide highly detailed imagery of the seabed and potential debris. iSURVEY can provide either ROV, pole-mounted or more traditional towed SSS systems. For towed systems, iSURVEY can provide the client with all the equipment and solutions needed, including winch system, depth sensor, vessel positioning and optionally USBL positioning of the SSS fish.

iSURVEY uses industry standard system and processing tools, and are able to deliver data in most known formats, depending on customers requirement.

Typical uses include debris survey, customer seafloor classifications and bathymetric data based on return signal.

Sub-Bottom Profiler Data Acquisition

iSURVEY provides services to gather and provide high quality sub-bottom profiler (SBP) data, using pole mounted or towed sensors. Sub-bottom profilers use low frequency acoustics to penetrate into the seafloor. iSURVEY is able to deliver data acquired with sub-bottom profilers to customers in most known formats.

Typical uses include detecting top layer thickness, pipe/cable detection, buried objects and customer geological and geophysical analysis.

Data Processing, Charting and Reporting

Supporting all elements of data acquisition both during seabed mapping and route surveys, iSURVEY offers data processing, charting and reporting of the acquired data. We provide customers with the tools and personnel needed to perform data processing, either on-board the vessel or using iSURVEY office facilities.

iSURVEY uses the full Eiva NaviSuite, together with supplementary tools such as GIS 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.
