UXOcontrol is now wholly owned by the N-Sea Group and continues to support the offshore industry through the delivery of UXO Risk Management. This includes the development of practical strategies for dealing with Explosive Remnants of War (ERW) and CBRNe (Chemicals, Biological, Radiological, Nuclear and Explosives) on land and underwater.

We have extensive experience with landfall and marine Unexploded Ordnance (UXO) Surveys, Investigation, Clearance and Explosive Engineering. Our experts have first-hand experience in varying international locations, working closely with our clients and collaborative partners which includes commercial entities, international organisations, local authorities, Humanitarian Mine Action agencies or through supporting national military operations and activities.

We can deliver the total UXO risk mitigation package in the marine environment, by utilising our 9-phase framework strategy, which brings your project management risks under control, delivered by our passionate, competent and qualified staff, using the latest technology for the delivery of quality UXO services. N-Sea is committed to continual improvement, technical innovation and new technologies, ensuring compliance with industry best-practice, national legal frameworks, licensing and explosive safety standards.

We are expert in understanding the requirements of reporting and evaluation in Explosive Ordnance (EO) risk management in order to deliver an UXO clearance certification, based on managing risks as low as reasonably practicable (ALARP).



The vessel 4-Winds is a modern offshore support vessel built in 2012. The 4-Winds has a proven track record when it comes to safe and efficient offshore operations. With her length of 60.25 metres, 14.95 metres beam and a draught of 5 metres, she is the ideal vessel to execute survey and other subsea tasks in the North Sea.

Disposal System

UXOcontrol operates COBRA Mine Disposal Systems, a non-electric firing system with a wireless ignition. This system is developed and manufactured by ECS Special Projects Ltd. and provides a safe, reliable, and cost-effective solution for the neutralisation or disposal of explosive ordnance.


With UXOcontrol’s next-generation MagSense system, you’re leaving nothing to chance. It’s a solution that takes unexploded ordnance (UXO) survey technology to the next level. MagSense delivers unprecedented accuracy, greater efficiency, and enhanced safety in the detection of UXO.
