The Kriegers Flak BC (Boulder Clearance) project concerns the boulder removal operations at predefined footprints for the subsequent jack-up barge operations for the WTG installation at the Danish Kriegers Flak OWF.
This wind farm of 72 locations, developed, designed, built, and operated by Vattenfall, is located in the Baltic Sea area. Specifically, the DKF site is situated in the eastern part of Danish territorial waters and the Danish Exclusive Economic Zone, directly next to the maritime border with Germany and Sweden. The closest distance to the Danish coastline (island of Møn) ranges between ca. 13 km and 39 km.
The presence of surface boulders at the Danish Kriegers Flak site was widespread throughout. This would pose several potential hazards to jack up vessel operations and subsequently a boulder mitigation strategy was required.
Vattenfall had awarded Asso a contract for the execution of boulder clearance works. The scope of works was performed by TSV Aethra and MSV Astrea, as per the below split.
