Marine Propeller Blade Inspection
A precise inspection workflow for marine propeller blades, built for shipyards, OEMs, and repair facilities that depend on accurate, consistent, and ISO-484 compliant measurement.
We manufacture a fully automated measurement system for propellers and impellers from product to analyzing.
Consistency You Can Trust
How We Can Help
During the grinding and fairing stage, technicians shape the propeller blade to its intended hydrodynamic profile. Small deviations in twist, camber, pitch, or overall geometry can emerge at this point, and even slight inaccuracies can reduce propulsion efficiency and raise fuel consumption. By inspecting the blade during machining and blade finishing, we identify these deviations early, allowing precise corrective work and minimizing the risk of downstream rework or scrapped components.
Use Cases
Repair & Refurbishment
Compare reworked blades against reference models to ensure alignment and pitch consistency. High-precision data ensures refurbished components meet OEM standards while maximizing energy output.
New Blade Production
Measure and verify blade geometry at each production stage to ensure structural integrity and aerodynamic performance.
Supplier Validation
Verify components received from external vendors before assembly to reduce downtime and guarantee quality across the supply chain.
GigaScan has partnered with TrueProp to bring unparalleled precision and efficiency to blade inspection and reporting. TrueProp’s automated ISO-484 evaluation eliminates the complexities of manual measurement; accounting for station geometry, hub alignment, and tolerance classification while generating fully compliant, traceable reports instantly. By integrating TrueProp, GigaScan empowers manufacturers and repair yards to deliver consistent, high-quality inspections, increase throughput, and confidently demonstrate compliance to customers and classification societies.
What We Deliver
We deliver precise surface accuracy, repeatable measurement, and fully traceable digital records through a streamlined, automated inspection flow. Each scan captures complete surface coverage across pitch, leading and trailing edges, and camber, while calibrated motion paths ensure consistent, repeatable results without manual variation. Every inspection is documented in a structured digital ISO-484 report (using TrueProp) that supports quality control, compliance needs, and clear assurance for manufacturers and their customers.
The Inspection Workflow
Step 01
The blade is positioned in the GigaScan lightbox for precise optical measurement and high-resolution data capture accuracy.
Step 02
GigaScan's high-resolution camera sensors capture images from a variety of angles and generate a detailed point cloud.
Step 03
During manufacturing, GigaScan can generate a color plot showing exactly where further grinding and fairing is required.
Step 04
After manufacturing is completed, an ISO-484 report is generated via the TrueProp software, ensuring accuracy.
Step 05
Finally, engineers and stakeholders can analyze the ISO-484 report and decide the next steps with confidence.
Precision builds trust. Our GigaScan inspection system helps marine manufacturers deliver consistent quality, confident performance, and verified accuracy. Blade after blade.
