We manufacture high-value, prefabricated modules from demanding wet units for shipbuilding to complex modules for industrial and construction projects. With full in-house capability, we deliver factory-finished modules that fit precisely, install quickly, and cut on-site time and risk.

Module manufacturing requires a mix of engineering precision, craftsmanship and logistics. At Hermann’s we combine all three:

  • Precise 3D engineering and model-based design to guarantee interfaces and tolerances.
  • Controlled factory pre-assembly and full test assembly so units arrive ready to install.
  • Specialist wet-unit expertise for marine projects (shipbuilding, offshore) plus other demanding applications.

Our approach guarantees consistent quality, reliable delivery and cost efficiency, even on the most complex projects. Hermann’s has a skilled design department and in-house, high-quality manufacturing capabilities, allowing us to deliver precisely what our customers want.

Refined work steps ensure a high-quality and repeatable module

Reference: Pre-Assembled Wet Units For an Efficient Refit Project in Spain

The refit project of Norwegian Cruise Line’s Epic in Cadiz required a fast and high-quality solution for renewing the vessel’s wet areas. Hermann’s met this need by delivering pre-designed wet units ready for installation on board. The modules were manufactured in Raisio and shipped in flatpack form directly to the site.
