Extensive areas of the UK and northern European coastline were heavily mined during World War 1 and World War 2 by both the British and German navies. Unexploded Ordnance (UXO) left over from these periods can pose a potential threat to the construction and operation of coastal and offshore projects. Ultrabeam offers a range of integrated geophysical services tailored to the efficient detection and location of seabed UXO.

We offer survey techniques to detect both ferrous and non-ferrous ordnance in a range of water depths. Multiple sensors are deployed simultaneously to detect objects lying at or buried just beneath the seabed and equipment spreads are optimised to provide the widest seabed footprint practically achievable for each survey line.

A combination of high frequency side scan sonar, multiple magnetometers, acousic seabed imager and electromagnetic techniques are all available along with survey advice or referral to a specialist unexploded ordnance risk management consultant.
