DEME has its own in-house site investigation company, G-tec, which can deliver the full package of geoscience services to both the renewables industry and the oil & gas sector. G-tec is specialised in offshore geotechnical and geological site investigations, geophysical marine and environmental surveys and deep-sea engineering services. 

In 2018 G-tec celebrated its 25th anniversary. In the same year, the company was active at several offshore wind farm sites, performing the site investigation for the SeaMade wind farm in Belgium and in France, it carried out the geotechnical studies for the 496 MW offshore wind project at Iles d’Yeu et de Noirmoutier with its multi-purpose drilling vessel ‘Omalius’. Additionally, G-tec performed site investigations for the Neart na Gaoithe Offshore Wind Farm, which will be located off the Fife coast in Scotland. G-tec also performed a geotechnical campaign and carried out studies along the Belgian coast deploying DEME Offshore’s jack-up vessel ‘Vagant’.
