Modern military and police diving teams operate in some of the most challenging environments imaginable. For decades, Port and Harbour clearance missions have relied on diver experience, tactile searches, and traditional sonar systems. While effective, these methods can be time-consuming, physically demanding, and inherently hazardous. Today, however, technology is reshaping the way underwater clearance operations are conducted. At the forefront of this transformation is Blueprint Subsea’s Artemis IRIS, a helmet-mounted sonar imaging system designed to give divers the ability to effectively “see” in blackwater conditions.

 

The Challenge of Port and Harbour Clearance

Ports and harbours are often congested, cluttered, and characterised by poor visibility, strong currents, submerged infrastructure, and an ever-present risk of encountering potential threats. Whether conducting explosive ordnance disposal (EOD), force protection, counter-narcotics inspections, underwater infrastructure security, or search and recovery operations, divers are frequently required to make critical decisions in conditions where vision alone is severely limited.

 

In a traditional clearance operation, divers may spend considerable time conducting methodical search patterns, repeatedly sweeping the same area to ensure no potential threat has been missed. Every additional minute underwater increases diver fatigue, oxygen consumption, exposure to hazards, and mission cost. The operational challenge is not simply finding an object. It is quickly determining whether a contact represents a genuine threat, benign debris, or an item requiring further investigation. The faster a diver can make this distinction, the more efficient and effective the mission becomes.

 

Seeing Beyond Visibility

The Artemis IRIS changes this paradigm by placing real-time sonar imagery directly within the diver’s field of view. Rather than relying solely on touch, intuition, or handheld displays, divers receive ultra-high-resolution sonar imagery via a binocular helmet-mounted display. The system combines high-definition visualisation with dual-frequency sonar technology, enabling users to transition seamlessly between wide-area scanning and close-range target identification.

 

For operators, this means greater confidence underwater. Potential objects of interest can be identified from a distance and approached with a clearer understanding of what lies ahead. Instead of searching blind, divers gain real-time situational awareness that supports faster and more informed decision-making.

This shift is particularly valuable during harbour clearance missions, where threats may be concealed beneath structures, attached to vessel hulls, or obscured by suspended sediment and marine growth.

 

Enhancing Safety Through Situational Awareness

One of the most significant benefits of Artemis IRIS is its contribution to diver safety. Underwater operations are often conducted under significant cognitive load. Divers must simultaneously track navigation, maintain communications, monitor life-support equipment, scan for hazards, and execute mission tasks. By presenting sonar imagery directly in front of the diver’s eyes, Artemis IRIS reduces the need to continuously transition between searching, navigating, and consulting separate display systems. The result is lower cognitive workload and improved focus during high-pressure operations.

 

For EOD teams, this enhanced awareness can be particularly valuable. Divers can better assess suspicious contacts before approaching them, maintaining greater standoff distances and reducing unnecessary exposure to potential hazards.

 

Faster Decisions, Faster Clearances

Efficiency is increasingly becoming a critical measure of operational success. Ports, naval bases, and critical maritime infrastructure often require rapid clearance to minimise disruption while maintaining security.

 

The Artemis IRIS enables divers to spend less time searching and more time classifying and resolving threats. By reducing uncertainty, teams can accelerate clearance operations without sacrificing thoroughness. This capability becomes even more powerful when integrated within the broader Artemis ecosystem. Blueprint Subsea’s Artemis range combines navigation, sonar imaging, positioning, and situational awareness tools that collectively support mission planning, execution, and post-mission analysis. This means faster location of evidence, improved hull inspections for contraband detection, and more effective search and recovery operations.

 

Supporting the Future Diver

Artemis IRIS effectively acts as a force multiplier. Less-experienced operators gain access to the same underwater visual information that would traditionally require years of experience to interpret through touch and intuition alone. Experienced divers benefit from faster target recognition and more efficient mission execution.

 

This evolution mirrors broader defence trends where technology is increasingly augmenting human decision-making rather than replacing it. Just as modern soldiers leverage enhanced sensors and digital situational awareness on land, divers are now gaining access to comparable capabilities beneath the surface.

 

The Future of Underwater Security Operations

As global maritime security requirements continue to grow, so too does the need for technologies that deliver safer, faster, and more effective underwater operations. Port and harbour clearance will remain a critical mission for military, police, and security agencies. The complexity of these environments is unlikely to decrease. What is changing is the technology available to those tasked with protecting them.

 

Blueprint Subsea’s Artemis IRIS represents a significant step forward in underwater operational capability. By enabling divers to navigate, identify, and assess contacts in conditions where visibility is effectively non-existent, it is redefining how clearance operations are conducted. Beyond providing better sonar imagery, IRIS delivers something far more valuable: confidence. Confidence to make decisions faster, confidence to operate more safely, and confidence that critical underwater threats can be located and assessed before they become operational risks.

 

For military and police dive teams tasked with keeping ports, harbours, and critical maritime infrastructure secure, that capability is rapidly becoming a mission-essential advantage.
