Underwater ROV & Submerged Asset Intelligence

Our enterprise ROV fleet operates to depths of 500 metres, covering the vast majority of infrastructure inspection requirements including wharf piles, dam walls, intake structures, pipelines, outfalls, seawalls, and offshore jacket structures. The ROVs are equipped with 4K cameras, powerful LED lighting (30,000+ lumens), multibeam sonar, and manipulator arms for close inspection and measurement. For assets in turbid or zero-visibility conditions, sonar provides complete structural mapping regardless of water clarity.

ROV inspection typically delivers 50-70% cost savings compared to commercial dive teams for equivalent asset coverage. Commercial dive operations require a minimum team of 4-6 personnel (divers, standby diver, supervisor, tender), hyperbaric equipment, medical support, and extensive WHS documentation. ROV operations require 2-3 personnel with significantly lower mobilisation costs, no weather standby charges for surface conditions, and no depth-related time limitations. The ROV can operate continuously for 8+ hours without fatigue or decompression requirements.

For visual inspection, condition assessment, and measurement tasks, ROVs replace divers in approximately 90% of scenarios. ROVs provide superior documentation (4K video, sonar mapping, photogrammetry), longer bottom time, greater depth capability, and zero personnel risk. Tasks that still require divers include physical intervention work (bolt torquing, anode replacement, marine growth removal) and some confined underwater spaces with complex access geometry. We assess each project individually and recommend the safest, most cost-effective approach.

We inspect wharf piles (timber, steel, concrete), dam walls and spillways, pipeline crossings and outfalls, intake and outlet structures, seawalls and revetments, bridge piers and abutments, culvert inverts, stormwater infrastructure, ship hulls, mooring systems, jetty structures, and offshore jacket structures. Our ROVs also perform bathymetric surveys for sediment mapping, scour assessment, and capacity calculations. All underwater data integrates with aerial and ground data into a unified above-and-below-waterline digital twin.

In turbid or zero-visibility conditions, our ROVs switch from optical cameras to multibeam sonar, which provides complete structural mapping regardless of water clarity. Sonar creates detailed 3D point clouds of submerged structures, identifying deformation, missing members, marine growth thickness, and scour profiles. In partial visibility, we combine sonar with close-range LED-illuminated video for comprehensive documentation. This means inspections proceed regardless of weather, tidal conditions, or water quality.

Yes. This is our core differentiator. We deploy aerial drones (above-waterline structures, decks, approaches) and underwater ROVs (piles, seabed, submerged components) in a single mobilisation, eliminating the need to coordinate separate providers with different schedules, standards, and data formats. All data is processed into a single unified digital twin that provides complete above-and-below-waterline asset intelligence. One provider, one mobilisation, one integrated deliverable.

Standard deliverables include 4K inspection video with depth and position overlay, high-resolution still imagery, multibeam sonar point clouds, bathymetric survey data, marine growth assessment, cathodic protection readings (where applicable), and a structured condition report with defect classification and severity ratings. For repeat inspections, automated change detection identifies deterioration between survey cycles. All data is georeferenced and accessible via our browser-based 3D platform without software installation.

Inspection frequency depends on asset type, material, environmental exposure, and regulatory requirements. Timber wharf piles in marine environments typically require annual inspection due to marine borer activity. Steel structures in seawater require 2-3 year cycles for corrosion monitoring. Concrete structures in freshwater may operate on 3-5 year cycles. Dam safety regulations typically mandate annual visual inspection with detailed engineering inspection every 5 years. We work with you to define the optimal cycle based on your specific risk profile and compliance obligations.
