LOHMANN Engineering
Design, calculation, and contract manufacturing – from a single point of contact with real project experience and a global network.
WHO ARE WE?
I am Marian Lohmann – a mechanical engineer, International Welding Engineer, and trained industrial mechanic who welded himself before starting to calculate. This combination of practical foundation and academic depth is no coincidence. It is the core of everything I do.
My path led from tool to drawing, from drawing to project, from project to responsibility for millions. As the overall project manager, I realized the world's first commercial project of a new environmental technology on an industrial scale – in Iceland, with a contract volume of 42 million euros, around 600 tons of steel construction, 12 kilometers of pipelines, and 30 pressure vessels. A facility of this kind had never existed anywhere in the world before. No reference project, no blueprint, no predecessor.
Pressure vessels that we have designed and calculated are currently in use in power plants around the world – including a hydrogen tank with a wall thickness of 50 mm and an internal pressure of 40 bar. About 350 tons of pipe supports from us bear loads in a nuclear power plant in Turkey. I am not just an office engineer – I actively work on-site and know the difference between theory and reality from personal experience.
What additionally sets me apart from a traditional office is my network: I collaborate with top-notch engineers and manufacturing partners in Egypt, Ukraine, India, and Vietnam – bringing together the best minds for each project, regardless of where they are in the world.
If you are looking for a partner who truly understands your project and does not shy away from responsibility – then you are in the right place.
