Built by the People Who Designed It

01

German engineering

“Calculated for your vessel. Not adjusted from a catalog.” Every rudder starts from your vessel’s data: hull form, operating profile, classification.

02

Flow simulation

“We simulate before we cut steel.” CFD analysis of the water flow around hull, propeller and rudder validates every design; model tests with renowned ship model institutes confirmed 5.3% savings for the combination rudder.

03

Our own production

“Not outsourced. Under our roof.” GME, our wholly-owned factory: CNC milling, lathe turning, robotic welding, sandblasting, coating, in-process inspection – 80 specialists working to our standards.

04

Delivery on schedule

“We control production, so we keep your date.” Direct coordination between engineering and factory, just-in-time logistics to your shipyard.

BEHIND THE SCENES

Inside Our Factory

Engineering expertise

Engineering first.

Every MM-Offshore rudder begins on the screens of our German engineers – CAD design, hydrodynamic calculation, CFD flow simulation – before a single plate is cut.

TECHNOLOGY

Precision Manufacturing

Every manufacturing step is performed in-house using advanced equipment and strict quality standards to ensure precision, consistency, and reliable delivery.

EXPANSION

A new factory is rising.

Starting beginning of 2027

Entrance gate of the new production facility under construction

A new production facility of around 29,000 is under construction - more capacity, more technology, same control.
