Unexploded Ordnance (UXO) are explosive weapons
(bombs, shells, grenades, land mines, naval mines, cluster munition, etc.) that
did not explode when they were employed and still pose a risk of detonation. In
Danish waters, more than 40.000 UXO still exist from 2nd World War.
These pose a risk for example to offshore installations of wind farms.
There is increasing focus on UXO detection and
clearance for offshore and coastal construction works, and there is a large
potential for optimization on methodologies for marine UXO detection.
Geophysical inversion of magnetic data collected at
Racebank offshore wind farm in the North Sea with the purpose of predicting the
size and burial depth of indivual UXO. If being successful, the results of this
project will be used by DONG Energy in future wind farm areas and for a fully
funded 3-years PhD position.

and 2nd World War that were found and disposed on Racebank in 2015-16
and on Gode Wind in 2014.
