Shock pulse monitoring in marine and offshore

SPM is a patented technique that utilizes signals from rolling element bearings as the basis for efficient condition monitoring of machines, offering instant evaluation of bearing condition in an easily understood green-yellow-red color scheme, and is widely used on vessels and offshore installations where reliable bearing performance is essential.

The Shock Pulse Method is a widely accepted philosophy for condition monitoring of rolling bearings and machine maintenance, particularly valuable in marine and offshore environments where bearings in propulsion lines, thrusters, winches, cranes, pumps, and auxiliary systems are exposed to varying loads, high humidity, and demanding operating conditions. Early and accurate detection of bearing deterioration supports safe operation and effective maintenance planning both onboard and offshore.

SPM HD – High Definition Shock Pulse Method

High Definition shock pulse monitoring in a very broad RPM range, including ultra low-speed applications (0.1 - 20 000 RPM range).

Shock Pulse Method dBm/dBc

For over fifty years, the original Shock Pulse Method (SPM) has been very successfully used to obtain a fast, easy, and reliable diagnosis of the operating condition of rolling element bearings.

Shock Pulse Method LR/HR

The LR/HR method allows the precision analysis of oil film condition in the interface between the outer and inner races and contains calculation models for finding the optimal lubricant.
