The company was formed as a joint venture between Bladt Industries and EEW at the factory established by TAG Energy Solutions.
The factory was used briefly in the late 2000s by Tees Alliance Group for a prematurely terminated contract to manufacture oil rig substructures.
[1][2] In 2008 the shipyard reopened under Tees Alliance Group (TAG) to construct the foundation structure of an oil rig 'SeaDragon 1', initially to be leased to Pemex (Mexico).
[8] In late 2014 Bladt Industries (Denmark) and EEW (Germany) acquired the assets of Tees Alliance Group Corporate, and formed a joint venture Offshore Structures (Britain) Limited to reuse the TAG Energy facility at Billigham.
[9][10] An initial contract was obtained in Jan 2015 for transition pieces for the Burbo Bank Extension offshore wind farm.
