Project detail
Every construction site needs to be surveyed before every use, so the Ground Penetrating Radar method is a good way to do that.
A Bathymetry & Debris Survey is a survey of underwater terrain and debris that may be present in bodies of water. This is usually done using special equipment such as a sonar, echo sounder and side-scanning sonar to map the depth and shape of the underwater environment. Survey results can then be used to identify potential hazards or debris that could pose a risk to navigation or other activities.
The most common type of Bathymetry & Debris Survey is the continuous topo-bathymetry survey with a point density of 10-20 points per square meter, accurate to 10 cm underwater and 5 cm above water. This type of survey can provide detailed information about the shape and depth of the ocean floor, as well as any debris or obstructions that may be present.
Like what PT Explora Prima did at the Jetty area of PT Wasco Engineering Indonesia last December. In the Bathymetry & Debris Work, PT Explora Prima involved geophysicists, surveyors and survey engineers. In addition to providing detailed information about the seabed such as updating water depth maps around PT Wasco Engineering Indonesia jetties, the Bathymetry & Debris Survey also helps identify potential hazards or debris that could pose a risk to navigation or other activities.
Process The bathymetry and debris survey methodology consists of a Multi Beam Echo Sounder (MBES), and a Side Scan Sonar (SSS) Sensor to determine water depth, seafloor contours, seafloor features, and debris identification. Vessel positioning and heading are supplied by Trimble BX992 DGPS with Marine Star Correction. Tidal observations during the survey were recorded by the Hobo Water Level Data Logger.
The work data that has been done includes the process of interpreting, checking, and compiling in a final report to show and find these hazards and debris, enabling more informed decisions about the best way to proceed with activities in the area.
Overall, the Bathymetry & Debris Survey is an important survey activity to understand and manage the risks associated with activities in the surrounding water bodies. They provide detailed information about the ocean floor and any potential hazards or obstructions that may be present.

Frequently Asked Questions
We regularly partner with clients across multiple demanding sectors, providing specialized survey support for Oil & Gas, Maritime and Hydrographic operations, Shipyards, Mining sites, Civil Infrastructure, and Plantations.
To ensure high precision and reliable deliverables, we utilize industry-standard instruments such as High-Definition 3D Laser Scanners, Hydrographic Echosounders, and UAV LiDAR systems, combined with advanced data processing software like Leica Infinity.
Timelines vary depending on the site location, area scale, and specific scope of work. While routine land or hydrographic surveys can be completed in a matter of days, more complex or large-scale projects require a structured timeline that we outline prior to mobilization.
We provide comprehensive, client-ready digital deliverables customized to your engineering and operational needs—ranging from 2D CAD layouts and 3D point cloud models to bathymetric charts and detailed technical reports.
Yes, we are. Backed by certified survey personnel, robust field equipment, and our certified ISO 9001:2015 quality management systems, we are fully prepared to execute both large-scale onshore and offshore assignments.
