Project description
The Gravity Base Structure (GBS) c/w Meteorological Mast was installed in the Eastern Development Area in Summer 2014 for Moray East OWF.
The integrity of the mast lattice structure was compromised during installation and as a result, requires to be decommissioned at the earliest feasible opportunity. Given the weight, size (33.5m x 32.5m x 16.0m) and position of the structure, a full assessment was required to determine the options for decommissioning. Considerable stakeholder engagement was required to identify suitable reception facilities and enabling assets to transport the structure.
