Hydrographic Surveys
Hydrographic surveys form the foundation of marine mapping and are conducted in line with International Hydrographic Organization (IHO) standards. At Accurate Survey, we deploy advanced systems to capture accurate seabed data for navigation, engineering, and design applications. Our Hydrographic Services Include:- Mapping water depths and underwater topography with high-resolution 3D imaging.
- Seafloor charting using Side Scan Sonar (SSS) to create detailed images.
- Below seabed profiling with sub-bottom profilers to analyze sediment layers and subsurface geology.
- Detection of natural and man-made features such as debris, shipwrecks, unexploded ordnance (UXO), subsea structures, and coral reefs.
- Pre- and post-engineering surveys for marine infrastructure.
- Pipeline and cable route investigations.
- Dredging support for ports, harbors, and coastal infrastructure development.
Bathymetric Surveys
As a specialized branch of hydrography, bathymetric surveys focus exclusively on water depth and seabed topography. Using Differential GPS/GNSS positioning systems, we deliver precision mapping that supports dredging, harbor expansion, and nearshore development projects. Capabilities Include:- Singlebeam and Multibeam Echo Sounder (SBES/MBES) surveys for accurate depth measurements.
- Beach profiling to assess shoreline dynamics.
- Tidal observations to support coastal engineering.
- Seabed sampling for material characterization.
Geophysical Surveys
Our geophysical surveys deliver detailed subsurface and seabed characterization, supporting both engineering design and construction. By combining advanced sonar systems with expert interpretation, we provide insights into soil conditions, sediment structures, and buried features. Applications:
- Pipeline and cable route assessments.
- Trenching and dredging operations.
- Port development planning.
- Side Scan Sonar surveys and mosaicking for high-resolution imagery.
- Edgetech 4125 Series Side Scan Sonar (SSS) for detailed seafloor imagery.
- Sub-bottom Profiling Systems (SBP) to visualize sediment and rock layers beneath the seabed.
- Geometrics G-882 Marine Magnetometer to detect ferrous objects and support archaeological or safety investigations.
Oceanographic Measurements
Understanding oceanographic conditions is vital for offshore operations, construction safety, and long-term coastal management. We offer a range of services that measure and analyze hydrodynamic forces. Our Capabilities Include:- Acoustic Doppler Current Profiler (ADCP) and current meter observations to study flow patterns.
- Tide gauges for precise tidal data monitoring.
These measurements are integral to offshore wind farms, port developments, and marine infrastructure projects.
Nearshore Geotechnical Investigations
Marine construction demands accurate knowledge of soil and rock conditions beneath the seabed. Our nearshore geotechnical surveys deliver essential data for the design, engineering, and installation of coastal and offshore structures. Services Include:- Barge-mounted rigs for shallow water drilling.

FAQ
A marine survey is a detailed inspection and assessment of ships, offshore structures, or water bodies to gather data on seabed conditions, water depth, environmental factors, and structural integrity. It is essential for safe navigation, coastal engineering, and offshore project planning.
Hydrographic surveys cover a broad range of water body studies, including depth measurement, seafloor mapping, and navigation safety. Bathymetric surveys are a specialized subset of hydrography focused specifically on measuring water depth and mapping the underwater terrain.
Geophysical surveys provide information about the seabed and subsurface, helping engineers and planners assess soil and rock conditions, plan dredging operations, and safely install pipelines, cables, and other offshore structures.
We use advanced technologies such as Side Scan Sonar (SSS), Multibeam and Singlebeam Echo Sounders (MBES/SBES), Differential GPS/GNSS, and sub-bottom profilers to collect accurate data on water depths, seabed topography, and subsurface structures.
Oceanographic surveys measure currents, tides, and other hydrodynamic factors that affect offshore and coastal projects. This data helps engineers design structures that withstand environmental forces and ensures safe marine operations.
Nearshore geotechnical surveys involve sampling and analyzing soil and rock conditions in shallow waters. These investigations provide critical information for the design, engineering, and installation of coastal and offshore infrastructure.
Marine surveys are crucial for shipping, port development, dredging, offshore oil and gas, renewable energy projects, subsea cable installations, and coastal engineering projects.
The frequency depends on project type, regulatory requirements, and environmental conditions. For infrastructure planning or safety compliance, surveys may be required before construction, periodically during operations, and after major events.
