PanGeo Subsea has recently been awarded its 20th unexploded ordnance UXO survey.
The North Sea offshore wind farm project will consist of a UXO survey covering an area of some 18km2 for export cables, inter-array cables and offshore platforms.
PanGeo’s sub bottom imager (SBI) will again be used as the sub-seabed depth of investigation is only to a maximum of around 6 metres.
According to PanGeo Subsea, the SBI has ability to reduce the amount of potential targets identified in earlier magnetometer surveys by up to 75%. In turn, this reduces the amount of actual targets which are subject to subsequent physical investigation, the company noted.
