AUV/USV Surveys

Subsea services

We deploy autonomous underwater vehicles (AUVs), uncrewed surface vessels (USVs), and crane-launched small boats for rapid seabed mapping and infrastructure inspection. Our vessel-agnostic approach ensures high-accuracy survey data with minimal mobilization requirements.

Autonomous Coverage from Harbour to Deepwater

Our AUV and USV survey services deliver high-resolution hydrographic and geophysical data with greater endurance, lower risk, and access to environments that conventional crewed vessels cannot safely or economically reach. Autonomous Underwater Vehicles fly close to the seabed — maintaining stable, precisely navigated flight paths that capture dense multibeam bathymetry, backscatter, sub-bottom, and optical imagery at resolutions that surface vessels at operational depth simply cannot match.

From deepwater field inspection campaigns to nearshore infrastructure monitoring and reservoir bathymetric surveys, our autonomous survey capability gives clients the spatial intelligence they need — with fewer people offshore and more confidence in every dataset delivered.Shape

How We Execute AUV/USV Surveys

AUV Pipeline & Corridor Surveys

Our AUVs are configured with multibeam echo sounders, side-scan sonar, sub-bottom profilers, high-definition cameras, and environmental sensors to fly low and precisely over pipelines, cables, and seabed corridors — capturing centimetre-scale resolution data across the full width of every survey pass. Multi-stage mission architectures are designed and executed sequentially — from broad reconnaissance sweeps and detailed pipeline inspection passes to targeted debris field identification and seabed change detection runs

Compact USV Deployment

We deploy compact, highly capable USVs integrated with precision GNSS/INS navigation and multibeam echo sounders into shallow, constrained, and environmentally sensitive areas where crewed vessels cannot safely or economically operate. Our USVs execute autonomous line-following acquisition missions that collect IHO-compliant bathymetry, acoustic backscatter, and surface data across the full survey area without the operational constraints, personnel exposure, or day-rate economics that crewed operations carry.

INS, DVL & Acoustic Positioning

Advanced navigation suites combining inertial navigation systems (INS), GNSS, Doppler Velocity Logs (DVL), and acoustic positioning aids maintain precise track spacing and sensor altitude throughout every mission — even in strong tidal currents, complex bathymetry, and GPS-degraded environments where lesser systems lose positional integrity. Integrated collision-avoidance systems operate continuously, ensuring safe, uninterrupted data acquisition across congested routes and structurally complex survey areas.

MultiSensor Data Fusion

Acquisition parameters, timing, and spatial referencing are standardised across all AUV and USV platforms from the outset, ensuring that bathymetry, imagery, sub-bottom, and magnetics datasets can be seamlessly merged into a single, consistent geospatial framework. Parallelised processing pipelines and automated QC workflows are applied immediately upon data ingest — delivering validated Digital Terrain Models (DTMs), acoustic mosaics.

What We Deliver: Autonomous Survey Intelligence

High Density Bathymetry & Imagery in Challenging Areas

Fully processed multibeam and side scan products from AUV and USV platforms, providing seamless coverage across deepwater fields, nearshore approaches, ports, and confined waterways that are difficult for conventional vessels. These datasets meet or exceed IHO and project specific specifications for depth accuracy and seafloor resolution.

Pipeline, Cable & Seabed Change Products

Route scale products that map pipeline and cable position, spans, exposure, debris, and seabed morphology, along with repeat survey change detection outputs for integrity and scour monitoring. Results are structured to feed directly into pipeline inspection software, burial assessments, and stability analyses.

Contact, Debris & UXO Target Catalogues

Contact reports and anomaly lists derived from high resolution side scan and, where fitted, magnetometer data, identifying debris, boulders, and potential UXO targets along corridors and around infrastructure. Each contact is supplied with position, dimensions, classification, and representative imagery or sonar snippets.

GIS, Modelling & Digital Twin Ready Survey Data

All AUV/USV outputs—DTMs, mosaics, contact layers, track lines, and quality layers—are delivered in standard GIS and modelling formats for direct ingestion into engineering, environmental, and digital twin platforms. This ensures autonomous survey data becomes an integral part of project design, operations, and long term asset management rather than a standalone dataset.
