Thruster Dynamometer Test Stand
NAIAD thrusters are rigorously tested under full load on our unique Dynamometer Test Stand. Before delivery each thruster is cycled in continuously reversing rotation against a propeller shaft load to dynamically test the performance of the bearings, seals, and hydraulic motor in a full load controlled real world test. NAIAD Thruster output, performance and quality are proven before launch!

 
Integrated Hydraulic System Test Apparatus  
NAIAD Integrated Hydraulic Systems are custom-configured to exactly suit a vessel’s unique array of hydraulically operated devices. Bringing a unique group of hydraulic consumers together can cause uninteded peculiarities. That’s why NAIAD’s in-house full system test capability utilizing our unique 285 HP Variable Speed Hydraulic Load-Sensing Test Apparatus is so special. 

Introduced in 2001, the full system IHS Test Apparatus definitively ensures that the system’s original design engineers, under measurable factory test conditions, solve any undesirable hydraulic anomalies such as “cross talk” among the various combinations of hydraulic consumers. This avoids wasteful post-installation troubleshooting by field service personnel operating under pressure and time constraints. The actual deliverable stabilizer, thruster, windlass, capstan, water pump, deck crane and all hydraulic consumers and components including main pumps contained in NAIAD IHS are tested together under real-world load conditions exactly as they will function in service. NAIAD’s system wide, Factory Acceptance Testing procedures raise the industry standard for proven and reliable IHS performance.

Stabilizer Roll Simulation Test Platforms
Every NAIAD stabilizer is factory tested as a full system on one of four Variable Frequency Roll Simulation Test Platforms. In addition to calibrating and optimizing controller settings to suit the vessel application, the entire system is hydraulically powered and fully operated. This pre-delivery functional test ensures absolute compatibility, harmonization and proven performance among all system components.
 
While time and labor intensive, our Factory Acceptance Testing ensures our customer’s actual deliverable system has met or exceeded all specifications and our demanding quality standards. Customers are invited to attend the FAT of their system.

Research & Development
In addition to full-scale field tests, NAIAD thruster propellers and stabilizer fins have been evaluated and optimized in a Hydrodynamic Research and Test Facility by professional hydrodynamists. Our cavitation tunnel testing, combined with our highly refined and adapted MDI Group capability in Computational Fluid Dynamics, yields highly reliable data and ensures optimum underwater design configurations.
