Project

Location

Greater Copenhagen area

Introduction

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.


Project

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.


Data

(1)  Dense magnetic anomaly data from Racebank offshore wind farm situated off the Norfolk coast in UK east coast and Gode Wind offshore wind farm in the German Bight (Data provided by DONG Energy; Simon Hviid).

(2)  Inspection reports from 41 large items of high explosives from 1st and 2nd World War that were found and disposed on Racebank in 2015-16 and on Gode Wind in 2014.

(3)  Detailed bathymetric Multi Beam Echo Sounder data

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
