Your propeller.
Engineered to outperform.
Proven to create value.
Renewed to last.
Less fuel or more speed - you choose.
From new-build design to remanufacture, Mencast connects intelligent engineering, advanced manufacturing and verification in one continuous lifecycle.
Meridian: 15% less fuel,
or 5% more speed.
That "better" has a name. The Meridian propeller and rudder cut the power your vessel needs, so you spend that saving as fuel at your everyday cruise, or as speed at full power - same hull, same engine, same gearbox. You choose which matters.

One Digital Model,
Carried Through Every Stage.
Three connected centres - intelligent design, distributed manufacturing and remanufacturing, and independent verification - share one validated digital model that flows unbroken from concept to a certified, traceable asset. Here's what each one does.
01Intelligent Design
AI-assisted design and CADCAM explore thousands of candidate geometries and rank them across the full range of operating conditions. The winning design leaves this centre as a fully validated digital model - and is offered as design-as-a-service.
- ✓AI-assisted design & CADCAM
- ✓Hydrodynamic & structural refinement
- ✓Efficiency & cavitation optimisation
- ✓Remote management
02Manufacturing & Remanufacturing
The same model flows to a distributed platform of autonomous cells that both build new components and restore worn ones - additive layer by layer, post-processed by robot, and measured throughout. One platform, whether the part is new or renewed.
- ✓Hybrid additive manufacturing & remanufacturing
- ✓Robotic post-processing & finishing
- ✓Digital metrology & inspection
- ✓Closed-loop intelligent monitoring
03Verification & Certification
Every component is checked back against its digital model and independently certified - producing the as-built proof, the Digital Product Passport and the sustainability metrics that travel with the asset for the rest of its life.
- ✓Model-based verification & certification
- ✓Digital Product Passport
- ✓Fuel-saving & carbon metrics
- ✓Verification, validation & trust
Where Digitalisation Proves Its Value.
A verified asset doesn't leave the digital model behind. Its Digital Product Passport goes into service with it, and the thread keeps running - now proving its value across the asset's working life.
Monitor
In service, the asset stays connected. Its Digital Product Passport and live performance data drive predictive, preventive maintenance - so wear is anticipated, not discovered.
Scan
On return, advanced scanning diagnoses its exact condition against the original digital model - inspection, measurement and a repair strategy planned digitally before any work begins.
Restore
Hybrid additive remanufacturing restores worn components to their intended geometry and performance - material added only where needed, surfaces re-profiled, the result logged back to the passport. The asset re-enters service renewed, not replaced.
Renewed, not replaced - every cycle measured: asset life extended, waste and carbon reduced.
Proof You Can Verify.
Nearly half a century designing, manufacturing and remanufacturing propellers, rudders and running gear for the world's fleets.
Among the first additively manufactured marine propellers certified by Lloyd's Register and qualified by ABS - results your own class surveyor can check against the as-built record.
