Ven-Tech Subsea offers a full suite of Unmanned Surface Vessels (USV) services designed for smarter, safer, and more efficient marine operations. Whether you’re conducting detailed hydrographic surveys, monitoring environmental conditions, inspecting submerged infrastructure, or operating in hazardous environments—our USV fleet delivers precision results with zero onboard risk.
From shallow inland waterways to deep offshore zones, our autonomous platforms reduce human exposure, cut operational costs, and deliver high-resolution, real-time data that accelerates decision-making.
Ven-Tech’s Unmanned Surface Vessels (USV) are ideal for:
Hydrographic surveys (multibeam/single beam)
Sub-bottom profiling & seabed stratigraphy
Environmental & oceanographic data collection
Cable & pipeline route tracking
Asset surveillance & perimeter patrols
Oil spill & slick detection
Harbor, port, and dredge surveys
UXO detection & debris mapping
Long-range offshore missions
Hydrographical Survey Services involve the precise measurement and mapping of underwater topography, water depth, and seabed features to support safe navigation, infrastructure planning, and marine construction.
Geophysical Survey Services involve the use of advanced sonar and sensor technologies to detect, map, and analyze subsurface conditions, sediment layers, and buried objects for engineering, environmental, and construction applications.
Geotechnical Survey Services involve the sampling and analysis of seabed and subsurface materials using tools like vibrocorers, CPT, and grab samplers to assess soil strength, composition, and stability for engineering and marine infrastructure design.
USVs equipped with high-resolution multibeam echosounders and RTK GNSS systems perform autonomous hydrographic surveys to map coastal, inland, and offshore water bodies with exceptional precision. Ideal for shallow, hazardous, or restricted zones, these platforms deliver safe, high-density data collection without requiring onboard personnel.
Unmanned Surface Vessels outfitted with side scan sonar, magnetometers, and sub-bottom profilers provide advanced geophysical profiling for subsurface analysis. These surveys detect buried structures, pipelines, UXO, and sediment stratification layers with minimal environmental disturbance — supporting pipeline routing, dredging, and environmental assessments.
USV platforms integrate automated sensors for NTU, pH, dissolved oxygen, chlorophyll, and temperature to conduct real-time water quality monitoring. Combined with water sampling systems and telemetry, they support environmental compliance, baseline monitoring, and effluent plume tracking in both regulated and remote environments.
Our USV fleet supports pipeline inspections, bridge pier assessments, and other submerged asset evaluations using forward-looking sonar, 4K cameras, and positioning systems. These missions are ideal for initial screening, low-visibility locations, and environments where diver entry or vessel-based survey is restricted or hazardous.
