De Vries Group STI Engineering

STI Engineering has worked in a wide variety of markets since it was formed in 1979, from combustion gas installations, coffee machines and loading equipment to hot stoves and blast furnaces. This broad yet highly specialised knowledge has undoubtedly strengthened the innovative capacity of the De Vries Group since the company joined in 2002.

STI combines state-of-the-art 3D-engineering tools with common sense and a sharp eye for client wishes to the smallest detail. It is an authoritative drawing and consultancy bureau for the shipbuilding and yachting industry, with pipe work systems being a particular specialty. Covering every aspect of the chain from specifications, system schematics and 3D models to drawings, pipe spools and Material Take Off, STI also provides technical consultancy services to various industries.
