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.

Triton ROV

The Triton XLX’s are a well-established and proven performer in shallow and deep-water operations. These ROV systems offer a comprehensive combination of thrust, payload, through frame lift and sensor interface.

Noordhoek Pathfinder

The Noordhoek Pathfinder is standard equipped as UXO clearance vessel. This means mobilised with self-launching Dual MAG wing for a wide span route survey and WROV with applicable UXO Inspection tools, vessel mounted USBL, multibeam, sub-bottom profiler as standard.

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 ERW and CBRNe on land and underwater.

In June 2016 both N-Sea Group (N-Sea) and Den Ouden Groep (Den Ouden) founded a 50/50 joint venture (JV), joining forces with the aim to ‘jointly market and execute UXO Survey, Identification and Disposal projects in the Netherlands, Germany, Belgium, Scandinavia and the Baltic States’. Since then, both companies have executed numerous projects together, and have extended activities to the UK and Ireland, and beyond.

After a successful period of the JV, both N-Sea and Den Ouden evaluated the merged activities and have determined that ownership and control should reflect the business expansion, thus taking the changing market and customer perspectives needs and expectations into consideration. Subsequently, N-Sea now wholly own and manage UXOcontrol.
