Condition monitoring for offshore vessels
Mission equipment like cranes, tensioners, and winches are fital for daily operations and should be monitored to avoid NPT.
Cranes, tensioners, windlasses, capstans, winches, etc., are only in use during operations, mooring, anchoring, and similar situations. If such equipment has rolling element bearings, there is a risk that those bearings can get damages at standstill because of vessel vibrations. Maintenance typically comprises only lubrication, oil changes, and certain minor inspections.
Patented technologies for ultra-low RPM applications
The Intellinova condition monitoring system measures the mechanical condition of deck and mission equipment in the most optimum way using a combination of techniques and signal optimization functions. Our patented SPM HD technology for advanced bearing and gear condition monitoring can measure at ultra-low revolutions – down to 0.1 rpm. Multi-parameter vibration techniques and functions as velocity, acceleration, 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 prewarning times of mechanical failures.
With Intellinova Parallel EN, shock pulses and vibration will be monitored seamlessly and warn operators instantly in case of excessive vibrations.
Two complementary technologies combined in one DuoTech accelerometer are installed on assigned positions and connected to the Intellinova data acquisition system.
The following problems can be detected:
- Rolling element bearing damages
- Gear wear and damage
- Imbalance
- Misalignment in shafts and gears
- Looseness
- Structural resonances
- Motor rotor and shaft eccentricity
- Electrical motor problems; broken rotor bars, VFD faults
- Soft foot
Online oil condition monitoring
Besides vibration condition monitoring, it is common to include our online lubrication and hydraulic oil condition monitoring solution to measure the contamination (particle counter) according to ISO or NAS class, water in oil detection, oil temperature, and oil quality.
