Danish water-and-environment engineering and software group based in Hørsholm, maker of the MIKE modelling software, with more than 60 years in the field. It has a registered Lisbon branch, and in December 2025 Portugal’s environment agency bought a DHI coastal-modelling licence for €115,000.
DHI has a registered branch in Lisbon, DHI Water & Environment – Sucursal em Portugal (NIF 980205905), at Rua Castilho 14-C, registered for hydraulic engineering. Its best-documented Portuguese customer is the state: on 1 December 2025 TED published the award by the Agência Portuguesa do Ambiente (APA), Portugal’s environment agency, of a software licence for coastal hydrodynamic modelling to DHI A/S, worth €115,000 (TED 795018-2025).
The licence is for DHI’s MIKE modelling suite, which is widely used by water authorities and coastal engineers to simulate floods, waves, currents and sediment movement. DHI A/S, headquartered in Hørsholm north of Copenhagen, employs 345 people in Denmark according to the Danish company register and works with the UN Environment Programme through the UNEP-DHI Centre on Water and Environment.
Portugal faces coastal erosion, drought and pressure on its water supply, and public agencies are buying the modelling tools to plan for them. Specialist Nordic engineering software companies such as DHI can win these contracts directly from Denmark, and a local branch helps them follow up with consulting work.
