In 2013 our parent company GD Energy Services SAU acquired NDSL, a specialist UK decommissioning company. This was soon re-branded GDES UK and has since enjoyed continued success in winning new business in the UK and Europe. The acquisition of GDES UK signalled a long term business commitment to the United Kingdom and intention to build our service offering and expand operations, relying on local staff and resources with high added value for our customers in the UK.
