Cockleshell Sea Mine Defence System
Know the threat before it becomes the incident.
The Cockleshell Sea Mine Defence System provides rapid subsea threat assessments for ports, harbours and critical maritime infrastructure.
We survey, analyse and identify underwater risks including sea mines, subsea sabotage, underwater drones, cables and infrastructure vulnerabilities.
Our team then delivers a clear, practical action plan with prioritised recommendations that can be initiated immediately.
Assess. Recommend. Protect.
Because protecting our ports starts beneath the waves.

Velter Cockleshell™ Sea Mine Defence System
Protecting Harbours, Shipping Lanes, and Lives
The Velter Cockleshell Subsea System is a next-generation, modular underwater defence platform designed to detect, prevent, and neutralise sea mine threats before they can cause catastrophic damage.
Inspired by the legacy of the Operation Frankton, Cockleshell brings modern AI, autonomous systems, and scalable deployment to one of the oldest and most dangerous threats in maritime warfare — sea mines.
The Growing Threat of Sea Mines
Sea mines remain one of the most cost-effective and disruptive weapons used in modern conflict and terrorism.
A single deployed mine can:
-
Block critical ports and shipping routes
-
Destroy high-value vessels
-
Trigger mass casualties
-
Disrupt global trade and energy supply
Strategic locations such as the English Channel, along with ports including Portsmouth Naval Base and Port of Southampton, are particularly vulnerable due to their economic and military importance.
