Condition monitoring of propulsion systems
Thrusters and other essential propulsion machinery must be monitored continuously to ensure early detection of deteriorating condition. With 24/7 monitoring, operators can take timely action to prevent catastrophic failures and plan overhauls at the earliest possible stage.
Integrated thruster monitoring
The Intellinova online vibration and oil monitoring solution includes an interface to the thruster controller, enabling correlation between measured vibration and operating parameters such as:
- Power
- Steering angle
- Blade pitch position
- Speed log
Reliable condition evaluation under varying running states
The vibration monitoring system uses HD condition monitoring technology and smart algorithms to handle varying running conditions. This enables dependable trending of vibration levels across all machine components, including bearings and gears.
Sensors for complete thruster monitoring
DuoTech accelerometers are installed on the electric motor bearing housings and on the upper housing of the thruster gearbox. An oil condition monitoring center with contamination (ISO/Nas class), water content, and oil quality sensor continuously measures gearbox lubrication oil for anomalies.

Set up to measure thruster mechanical condition most optimally, the Intellinova condition monitoring system offers a strong combination of techniques and signal optimization functions; our patented SPM HD technology for advanced bearing and gear condition monitoring at ultra-low rotational speeds, down to 0.1 rpm. Commonly used vibration analysis techniques like velocity, acceleration, and HD ENV, FFT spectrum, time domain and phase analysis, Pseudo tach, time-synchronous averaging, and HD Order Tracking form a unique package of tools included in our thruster condition monitoring solution to maximize pre-warning times of mechanical failures.
The following problems can be detected:
- Rolling element bearing damages
- Gear wear and damage
- Imbalance in drive shaft and propeller
- Misalignment in shafts and gears
- Looseness
- Structural resonances
- Propeller blade damages, marine growth, erosion, and cavitation
- Rotor and shaft eccentricity
- Electrical motor problems; broken rotor bars, VFD faults
- Soft foot
Besides vibration condition monitoring, it is a common choice to include our online lubrication and hydraulic oil condition monitoring solution for thrusters to measure the contamination (particle counter) according to ISO or NAS class, water in oil detection, oil temperature, and oil quality.
Intellinova online vibration monitoring systems is your best and affordable choice and easy to retrofit.
