Noka Offshore GmbH is currently constructing a
submarine HVDC-cable between Germany and Norway.
These construction efforts are part of the 516 kilometre
long NordLink power network which crosses German,
Danish and Norwegian waters. Before the cable can
be placed, it is imperative to survey the seabed for
unexploaded ordnance (UXO). Noka Offshore has granted
a part of these surveys to the joint combination BODAC/
N-Sea. Between the North-German city of Büsum and
the Danish-German border the seabed has been scanned
with multibeam echo sonar (MBES), side-scan sonar (SSS),
magnetometer and gradiometer equipment. BODAC
analysed the data of these scans to provide a clear picture
of unexploaded ordnance still present in the seabed. When
necessary BODAC removed dangerous objects along the
sea-corridor.
In order to increase the storage and handling capacity
of the Koole Terminals in the port of Rotterdam, it was
decided to realise an additional quay. In order to safely
create the quay, it is necessary to first inspect the area for
the presence of unexploded ordnance (UXO). This work has
been executed by BODAC. Based on historical research
of the area, it was determined that aerial bombs could
be found up to 7 meters below sealevel at the terminal
location. Using our own sophisticated equipment BODAC
was able to detect anomalies up to 11 meters below
ground level and ensure future safety at the construction
site. Our specialized equipment made it possible to survey
the area with minimal excavation work. This way the
client is ensured that he can start construction of the new
quay as fast and safe as possible.
