Our Story

        PT Geosans Global Solution is a company specializing in engineering-quality marine and land geospatial data. This means the company provides spatial data (location-based data and positions on the Earth's surface) for both marine and land areas. This data is used for engineering, project planning, and decision-making purposes in various industrial sectors, particularly:

  • Offshore energy projects, such as oil and gas and renewable energy (wind farms, tidal energy).
  • Subsea telecommunications cables.
  • Ports and coastal infrastructure.
  • Renewable energy developments, such as offshore wind or solar marine platforms.

Our Mission

Deliver engineering quality survey data and complete solutions that reduce project risk

Innovate continuously by adopting appropriate sensors and automating processing workflows

Operate to the highest standards of quality, health, safety, and environmental performance to protect people and ecosystems

Build long term partnerships with clients and supply chain partners through transparency and technical excellence

Our Methods

Multibeam Bathymetry for high resolution seabed mapping, digital elevation model production, and backscatter mosaics; Side scan sonar for seabed imagery and object detection; Sub bottom profiling for shallow stratigraphic imaging and geohazard identification; Magnetics and gravity surveys for detection of buried ferrous objects and unexploded ordnance screening; Rig & vessel positioning services including barge management and positioning support for rig moves and mooring layouts; Metocean monitoring using CTD casts, tide gauges, current meters, and wave sensors for design and installation planning; Dredging monitoring and as laid surveys to verify dredge depth and project progress.

Ultra High Resolution Seismic 48 Channels

Equipped With Airgun

The reflections from the subsurface are assumed to lie directly below the sail line that the seismic vessel traverses – hence the name 2D. The processing of the data is, by nature of the method, less sophisticated than that employed for 3D surveys. 2D lines are typically acquired several kilometer apart, on a broad grid of lines, over a large area.

Singlebeam & Multibeam Bathymetric Surveys

Bathymetry Solution

Sonar projector requires continuously producing acoustic pulses with appropriate precision, control, and repetition with the same character. The projector used is made of piezo-electric ceramic material, a material that can change if imposed voltage. Echosounders use some fatherly voltage causes the piezo-electric projector oscillates, emitting a wave of press with a certain frequency characteristics into the water.

Side Scan Sonar

Seabed Scan Imagery

It was only in the early 1960's that Dr. Harold Edgerton (an electrical engineering professor at the Massachusetts Institute of Technology) started to adapt his techniques on high-speed flash photography to acoustics, having concluded that photography was not best suited to the murky conditions underwater By sending 'flashes' of acoustic energy into the water and recording the echoes, Edgerton (who later worked with famous French underwater explorer Jacques Cousteau), developed a towed side-looking sonar that could create a continuous image of the seafloor.

Core Capabilities

  • Produces high-resolution seafloor topographic maps (Digital Elevation Models/DEMs).
  • Applications: submarine pipeline design, cable routing, sediment analysis, and navigational safety.
  • A tool used to create images of the seabed using acoustic waves.
  • The result is backscatter mosaics, which show the texture and characteristics of the seabed surface (rocks, sand, sunken objects).
  • Used for obstacle detection, wreck investigation, or project area inspection.
  • Technology for mapping subsurface layers.
  • Useful for understanding geological structures and stratigraphy, which are essential for analyzing the foundations of marine structures, pipelines, and submarine cables.
  • Surveys to measure Earth's magnetic field anomalies caused by ferromagnetic minerals beneath the surface.
  • Applications: Detection of buried metal objects, UXO (unexploded ordnance) surveys, and geological mapping.
  • Global Navigation Satellite Systems (such as GPS, GLONASS, and Galileo) are used for highly precise positioning during surveys.
  • They ensure the spatial accuracy of geosurvey data, particularly in vessel positioning and data alignment operations.
  • All survey results are processed and presented in CAD (Computer-Aided Design) and GIS (Geographic Information System) formats.
  • This allows for spatial visualization, data analysis, and the creation of engineering maps and interactive 3D models.
