Engineering and design

BHDT focuses on engineering as one of its main competences.
The basis of our engineering work is our customers’ specifications, which include process engineering fundamentals on the one hand, and basic design specifications on the other.

By providing tailor-made solutions, BHDT supports our customer in optimising their design. Compliance with design codes and local regulations is the basis of our engineering activities. We use state-of-the-art software tools specifically for that purpose.
