Hydrographic Surveys
Hydrographic Surveys
Precision Engineers & Surveyors delivers high-accuracy hydrographic surveys in accordance with IHO C-13 Manual on Hydrography and IHO S-44 Survey Order standards. Our services include Multibeam Echo Sounder (MBES), Single Beam Echo Sounder (SBES), Side Scan Sonar (SSS), Sub-Bottom Profiling, and Magnetometer Surveys, providing reliable bathymetric, seabed, and subsurface data for dredging, navigation, port development, and offshore engineering projects.
Key Services
- Multibeam Echo Sounder (MBES) Surveys PEAS conducts high-resolution Multibeam bathymetric surveys in accordance with IHO C-13 and IHO S-44 Survey Order requirements, providing full-seafloor coverage and accurate depth measurements. Our MBES surveys support dredging control, navigational safety, seabed modeling, and detailed marine engineering design.
- Single Beam Echo Sounder (SBES) Surveys To measure water depths along defined survey lines for channel monitoring, volume calculations, reconnaissance surveys, and routine hydrographic assessments. SBES surveys provide cost-effective and reliable depth information where full seabed coverage is not required.
- Side Scan Sonar (SSS) Surveys To image and characterize the seabed surface for identification of objects, obstructions, debris, and seabed features. SSS surveys are used for pre- and post-dredging assessments, hazard detection, pipeline and cable route surveys, and marine infrastructure planning.
- Sub-Bottom Profiling Surveys To investigate subsurface sediment layers and shallow geological structures beneath the seabed. Sub-bottom profiling supports dredging design, sediment thickness evaluation, and assessment of seabed conditions for coastal and offshore engineering projects.
- Magnetometer Surveys To detect and locate ferrous metallic objects buried on or beneath the seabed, including wrecks, anchors, and unexploded ordnance. Magnetometer surveys help reduce construction risks and enhance safety for dredging and marine development activities.
- Dam and Reservoir Surveys Inspecting dam structures and reservoirs to assess sedimentation, water storage, and safety.
