The Unexploded Ordnance (UXO) risk mitigation solutions expert UXOcontrol and it’s exclusive partner EORCA UK formally launch HYDRA©, (patent pending). The worlds first “Low-Yield” solution for the disposal of live UXOs. This unique technique is really a game changer to protect sea life and the environment against the destructive effect of a “High-Order” detonation. 

It is known and well documented that when attempting a “Low-Order” technique, the outcome cannot be guaranteed and a “High-Order” Detonation could at worst-case result. It is therefore necessary when planning a “Low-Order” to ensure that all the mitigation measures for a potential High-Order Detonation are in place. With the use of HYDRA© due to the specific design and material of the internal liner and multiple reciprocating high-pressure targeted hyper liquid-jets, there will be absolutely no possibility of a “High-Order” Detonation. The Target will be rendered safe and neutralized following the Disruption and Disintegration of the explosive filling and any mechanical fusing / electrical components by the high-pressure liquid jets. This system removes the need for a bubble curtain vessel and reduces environmental harm greatly. 

UXOcontrol delivers high quality EOD services and has quick response teams, permits and assets ready to serve our clients globally on short notice and to offer all three recognised disposal techniques.

High-Order – specific and intended placement of the Cobra or Barracuda Bomb & Mine Disposal System (110mm Variant 1.5 to 5Kg Net Explosive Quantity NEQ), accredited with over 1750 Live UXO Disposals since 2009 without incident or failure, by remote means. Deliberately generate a plasma jet or a blast-fragmentation event (as determined by the EOD Operator on-site) in very close proximity to and targeting the known, vulnerable components of the UXO, which will result in the explosive filling of the UXO detonating and producing a High-Order outcome. Probability / Success of intended outcome = 100% and guaranteed. Post-Detonation activity requirement at As-Left survey is minimal consisting of confirmation of the expected High-Order result, measurement of the blast-crater at the seat of the explosion, recovery of small pieces of shrapnel / non-explosive metallic arisings. Issue Explosive Free Certificate on completion and close-Out Target. 

Low-Order – specific and intended placement of the Cobra or Barracuda Bomb & Mine Disposal System (30mm Variant, Shaped-Charge or Ballistic-Disc (as determined by EOD Operator on-site), 30-80grms NEQ), accredited with 10 Live-Firing Trial shots since 2009 without incident) by remote means. Deliberately penetrate the casing of the UXO at a specific entry point and introduce a small “clinical” plasma jet into the main explosive filling. The intention is to excite the explosive molecules within the main filling and hopefully generate enough pressure within and eventually “burst“ the UXO casing, producing a “Deflagration” (disruption / break-up of the main filling). Probability / Success of intended Low-Order outcome approx. 80-90%, but cannot be guaranteed.

Issue Explosive Free Certificate on completion and close-out Target. All recovered explosive material has to be wet-stored onboard and eventually disposed of post De-Mob at a registered Disposal Facility. 

Low-Yield – specific and intended placement of multiple Barracuda Bomb & Mine Disposal System (110mm HYDRA© Variants 0.75Kg NEQ each), accredited with 10 Live UXO Disposals since 2015, without incident or failure, by remote means. Deliberately generate multiple reciprocating high-pressure, hyper liquid jets, simultaneously, in very close proximity to and targeting the known, vulnerable components and main explosive filling of the UXO. This will result in the disruption and disintegration of the same without the possibility of a “High-Order” outcome. Probability / Success of intended outcome = 100% guaranteed. Issue Explosive Free Certificate on completion and close-out Target. All recovered explosive material has to be wet-stored onboard and eventually disposed of post De-Mob at a registered Disposal Facility. 

Lt Cdr Adrian Dann, EORCA’s founder, commented: “During Low-Order disposals we have to plan for High-Order due to the industry accepted 10%-20% chance of a High-Order occurring. HYDRA is a Low-Yield technique that 100% guarantees that a High-Order will not occur. The HYDRA system was recently used and completed a safe disposal as planned for National Grid”. Lt Cdr Dann brings over 20 years’ UXO experience in the Offshore Industry and 26 years’ active service in the Royal Navy as a Maritime Mine Warfare and Mine Clearance Diving, EOD specialist and is UXOcontrol’s EOD Superintendent. 

N-Sea CEO, Arno van Poppel commented: “Our exclusive agreement with EORCA UK has been a great success during 2020. HYDRA is another technical solution that reduces cost, risk and environmental impact for our clients”. 

Den Ouden CEO, Jeroen den Ouden commented “UXOcontrol has built an enviable track record of UXO survey, identification and disposal, offering its one-of-a-kind service. This new Low-Yield techniques adds to our suite of tools for safely dealing with UXO.”

UXOcontrol combines the expertise and experience of its two parent companies. N-Sea, a leading survey and IRM subsea solutions provider, delivers effective and cost-efficient subsea support services to asset operators and tier one contractors within the energy industry, whilst BODAC (part of the Den Ouden Group), a leading UXO risk mitigation company, is certified in Historical research, archaeology, UXO surveying, identification and neutralising explosives in land and marine environment.
