A nation’s security extends beyond what is we see. It is shaped by the people who protect it, the capabilities we build, and the preparedness to meet challenges across every domain.

This Indian Air Force Day, we salute the air warriors who defend our skies with courage, discipline and an unwavering commitment to the nation.

As India continues to strengthen its capabilities across land, air, sea and the underwater domain, the larger purpose remains the same: a stronger, more secure nation.

Today, we honour those who serve and safeguard our country.

Jai Hind. 🇮🇳

Knowing a reservoir’s depth is not the same as knowing its storage capacity.

A reservoir’s capacity depends on the shape and contours of its bed, not just the water level or depth at a particular point. Over time, sediment carried by rivers settles on the reservoir bed, gradually changing its profile and reducing the volume of water it can store. This process, known as sedimentation, can make a reservoir’s actual capacity differ significantly from its original design.

The scale of the issue is reflected in the Central Water Commission’s 2024 Compendium on Sedimentation of Reservoirs in India. Across 439 reservoirs for which usable survey data were available, the average loss in gross storage due to siltation was calculated at 19.24%.

This is where bathymetric surveys become important. By mapping the underwater contours and depth of a reservoir, they help establish its current bed profile and estimate its storage capacity. Repeated surveys can then reveal how that profile changes over time, providing valuable information for water-resource planning and reservoir management.

Coratia’s Navya autonomous surface vessel conducts hydrographic and bathymetric surveys using integrated positioning technologies, including GPS, USBL and DVL. This enables detailed reservoir mapping and supports comparisons across successive surveys.

Because managing a reservoir effectively requires more than knowing how much water it holds today. It requires understanding how its capacity is changing over time.

Seeing beneath the surface is only part of the equation. Understanding what lies beyond it is what makes underwater inspection effective.

Underwater environments present unique demands on inspection technology. Limited visibility can affect visual assessment, while the absence of GPS signals underwater makes accurate positioning and navigation more complex. This is why reliable inspection often depends on multiple technologies working together.

Cameras capture visual details, sonar helps map underwater surroundings, and positioning systems track a vehicle’s location. Together, they provide a more complete picture of submerged infrastructure.

At Coratia, underwater robotics brings these capabilities together to support inspection in challenging underwater environments. The focus extends beyond capturing footage to gathering meaningful data that can inform assessment, monitoring and maintenance decisions.

Because understanding the underwater world takes more than just a view. It takes the right technology to interpret it.

Some of the biggest changes begin with a simple belief, that a better tomorrow can be built.

On Gandhi Jayanti, we remember Mahatma Gandhi and a legacy rooted in truth, courage, simplicity and the conviction to turn belief into action.

𝗔𝘁 𝗖𝗼𝗿𝗮𝘁𝗶𝗮, that spirit resonates with our own journey of building indigenous technology for challenges that are often hidden from view. From exploring what lies beneath our waters to developing robotics for critical infrastructure, we continue to believe in questioning what is possible, building for India and moving forward with purpose.

Because progress is not only about going further. It is also about having the courage to explore what lies beyond the visible.

Wishing everyone a meaningful Gandhi Jayanti.

What does defence-grade mean when you’re inspecting a dam, pipeline or port?

It means the technology has already been tested where failure is not an option.

Coratia’s Jalasimha UWROV achieved TRL-9, the highest level of technology readiness, before being inducted by the Indian Navy under a ₹66 crore iDEX contract.

But the value of that validation goes beyond defence.

The same capabilities that enable underwater operations in challenging conditions can support civilian and industrial inspection, helping organisations inspect infrastructure with greater reliability, precision and efficiency.

From bridges and pipelines to reservoirs and ports, Coratia is taking proven underwater robotics from defence applications to the infrastructure that keeps industries running.

Defence-grade should not mean defence-only.

Strengthening India’s Offshore Energy Infrastructure

India’s offshore energy infrastructure is entering an important phase of renewal and modernisation.

ONGC is undertaking major Pipeline Replacement Projects across its Western Offshore fields. This includes approximately 285 km of subsea pipeline under PRP-9 across Mumbai High, Neelam-Heera, Bassein and satellite fields, along with extensive topside modifications across offshore platforms.

As India continues to strengthen the resilience and efficiency of its offshore energy assets, inspection and integrity assessment become equally important, helping operators understand asset condition, prioritise interventions and plan maintenance with greater precision.

This is where subsea robotics can play a critical role.

ROVs enable detailed, repeatable inspection of underwater infrastructure, including free-span measurement, burial-depth assessment, corrosion mapping and ultrasonic thickness measurement. ONGC’s own subsea pipeline scopes include ROV-based integrity inspection alongside installation and rehabilitation activities.

At Coratia, our offshore service capabilities span platform and subsea infrastructure inspection, pipeline integrity assessment, corrosion and structural health monitoring, and ultrasonic thickness measurement.

Our experience includes offshore and industrial inspection work in India, including with IOCL at Paradip, as well as an invitation to Brunei Darussalam to demonstrate integrated robotic systems for subsea inspection of offshore energy infrastructure.

As India invests in the next generation of offshore infrastructure, building the capability to inspect, monitor and maintain these assets domestically will be an important part of strengthening the entire ecosystem.

The technology to inspect India’s offshore assets should be built in India, for India’s offshore needs.

This World Water Monitoring Day, let’s look beneath the surface.

For a country with a vast coastline, monitoring our waters is about much more than measuring what happens at the surface.

India’s coastal waters are home to critical infrastructure, ports, harbours, pipelines and underwater assets. Their condition can change over time - through corrosion, marine growth, sedimentation, structural wear and changing underwater conditions.

Regular inspection helps us understand these changes early, build reliable data and make better decisions about the infrastructure and environments that depend on our waters.

But much of this remains difficult to access, particularly in deep, low-visibility or hazardous underwater environments.

This is where underwater robotics can make a difference.

At Coratia, we are building robotic systems that enable underwater environments and infrastructure to be inspected, mapped and monitored with greater visibility and precision - reducing the dependence on human divers in challenging conditions.

Because India’s relationship with water is not only about what happens on the surface.
It is also about understanding what lies beneath it.

This World Water Monitoring Day, the message is simple:

Monitor. Inspect. Understand. Protect.

Engineering is where ideas take shape, challenges become solutions, and vision is turned into something that can serve the world.

On Vishwakarma Puja, we celebrate the engineers, innovators, technicians and skilled hands whose work strengthens the foundations of what we build — from machines and infrastructure to the technologies that will define India’s future.

Every breakthrough begins with the people who have the skill, persistence and imagination to build it.

Here’s to those who keep building, improving and creating — and to a stronger, more self-reliant India.

Wishing everyone a very Happy Vishwakarma Puja.

A vehicle descends into the water and returns with what it was designed to find. That is the outcome people see.

What remains unseen is the engineering precision that makes that outcome possible - the systems, decisions and countless details that must work together flawlessly, often in an environment where there is no room for error.

The seal that held at depth.
The thruster that responded.
The positioning that knew exactly where the vehicle was.
The code that made the right decision hundreds of metres below, with no one there to intervene.

Every one of those was an engineering problem. And usually, one that had to be solved more than once.

Underwater engineering is unforgiving. There is no partial credit and no quick correction. The environment either accepts your design or exposes it.

That is the standard our engineers work to every day-testing, rebuilding and refining until almost right becomes right.

To the team at Coratia, and to every engineer in India building what the country can rely on - thank you.

Happy Engineers’ Day.
