Survey, inspection and conservation — delivered by machine

Five kinds of work, all carried out by unmanned platforms that keep people off the water and out of it.

Bathymetric Survey

Knowing the true shape of the bed under a water body is the foundation of almost every decision made about it — storage capacity, dredging volumes, navigability, sedimentation rate. We run survey lines with sonar-equipped unmanned catamarans and deliver processed depth models rather than raw logs.

Reservoir and dam capacity surveys
Canal and irrigation channel profiling
River and estuary bed mapping
Port, harbour and jetty approach surveys
Pre- and post-dredge volume comparison

Underwater Inspection

Submerged infrastructure fails out of sight. Our inspection-class ROV puts HD video on dam walls, hulls, piers and jetty piles without scheduling a dive team, which means inspection can happen on the asset’s schedule instead of the diver’s.

Dam wall and spillway inspection
Ship hull and propeller survey
Bridge pier and abutment checks
Jetty pile and quay wall condition surveys
Post-incident and pre-monsoon assessments

Water Quality Monitoring

A single sample tells you about one point on one day. Unmanned platforms make sampling repeatable and affordable enough to build an actual time series across a whole water body, which is what reveals a trend.

Multi-point in-situ sensor runs
Spatial water quality mapping
Repeat monitoring campaigns
Reservoir and lake health baselines
Research-grade data collection for institutions

Water Conservation

Most Indian reservoirs hold less than their design capacity because of silt nobody has measured recently. Quantifying that loss is the first step to doing anything about it, and it is work our conservation programme exists to carry out.

Siltation and sedimentation studies
Live storage capacity reassessment
Desilting prioritisation support
Catchment impact assessment
Long-term capacity trend monitoring

Green Passenger Mobility

The same engineering that makes an unmanned vessel efficient makes a passenger craft cleaner. Our green mobility work brings electric propulsion to inland passenger routes, tourism operators and backwater transport.

Solar-electric passenger craft
Low-noise tourism and heritage-lake operation
Zero-emission inland transport routes
Reduced operating cost per passenger-km
Custom craft for operators and authorities

Questions

What teams usually ask first

How long does a reservoir survey take?

It depends on surface area, the line spacing the accuracy target demands, and access. A small reservoir can be a single day on the water; a large one is planned in stages. We give an estimate in the survey plan before mobilising so there are no surprises on cost or schedule.

Can you survey while the reservoir stays in service?

Yes. An unmanned surface vessel does not require the water body to be drawn down or taken out of service, which is one of the main reasons authorities choose this method over conventional survey.

What formats do you deliver data in?

Processed depth models, contours and cross-sections, supplied in the GIS or CAD formats your team already works in, together with a method and coverage report.

Do you handle the regulatory permissions?

We advise on what is required and support the application, but permission to operate on a given water body normally rests with the asset owner or the relevant authority. We agree who is doing what before the project starts.

Have a water body that needs looking at?

Tell us the site and the question you need answered. We will tell you which platform and payload we would bring, and what it would cost.
