Underwater drones seek and destroy mines
Peter Mallett, Staff Writer — A new Remote Mine-hunting and Disposal System (RMDS) may soon make jobs safer and easier for Royal Canadian Navy (RCN) dive teams. Kraken Robotics, a marine technology company based in St. John’s, Nfld., has been awarded a $50-million contract to produce an RMDS system for the Department of National Defence (DND). The underwater drone technology is intended to help the Canadian Armed Forces support Naval Mine Countermeasures operations with allies and in United Nations peace operations. “RMDS would dramatically enhance readiness and survivability in mine-threat environments while reducing the risk of potentially losing ships and lives to a sea mine,” said Lieutenant-Commander (LCdr) George MacLean of the RCN is Directorate of Naval Requirements office and RMDS Project Director. The RMDS system includes the ability to detect, identify and adequately dispose of a sea-mine threat from a safe distance using Autonomous and Remote Operated Vehicle (ROV) technology to depths of 200m. Since Canadian warships regularly deploy overseas to locations where mine threats are high, the technology is a potential game-changer for deployed vessels. LCdr MacLean believes RMDS will greatly enhance safety for Canadian and allied ships currently deployed and supporting such missions as Operation Reassurance in Eastern Europe. How it works The RMDS system consists of two classes of Autonomous Underwater Vehicles (AUVs). A Lightweight AUV is designed for long-range deep water at depths of 100-200 metres. It has a long-life battery, making them capable of covering larger areas and can be launched from a ship’s crane or the shore. Meanwhile, the Operator Portable AUVs, equipped with Kraken’s AquaPix synthetic aperture sonar, is designed for shallow water operations at shallower depths of 10-100 metres. The system may be deployed by as few as two operators from a ship, a small boat or from the shore. When a mine is identified and determined that it needs disposal, a second ROV, the Sea Fox Mine Disposal System, is deployed to dispose of the mine at a safe distance...
