Condition Based Maintenance Programme Results In £295,000 Cost Avoidance

GulfMark, a provider of marine transportation services, tasked PCMS Engineering with rolling out a (CBM) Condition Based Maintenance Programme throughout their modern fleet of offshore vessels with the goal of improving their maintenance strategy and reducing maintenance costs.

By implementing vibration and stresswave technologies throughout their fleet, GulfMark staff are able to utilise the data, analysis and technical readings to make critical maintenance decisions on key assets to optimise maintenance actions; ensuring maximum asset availability.

The Challenge

Monitoring support bearings within tunnel thrusters is a complex task due to the difficult-to-access location of the thruster bearings. PCMS Engineers utilised multiple CBM technologies to determine the asset condition and remaining life span, which is a key part of the PCMS service offering.

The Solution

By using vibration and stresswave technologies to determine transmitted vibration from the depths of the machine, PCMS Engineers were able to indicate activity relating to bearing deterioration.

The ability to detect minute levels of vibration within a signature is due to the distance from the point of deterioration, which is a key benefit of stresswave technology.

The correct application of technology enables Gulfmark to optimise its maintenance planning to avoid costly stoppages whilst offshore, and means that the exact fault location can be pinpointed avoiding a complete dismantling and overhaul.

The Results

PCMS Engineers detected deterioration in the first support bearing on the input shaft to the thruster, which required consistent monitoring over a period of time to determine the rate of deterioration.

The rate of change detected indicated that the bearing needed to be replaced. The bearing replacement and general inspection was completed during a port call with minimal interruption to the vessel’s operations, and upon inspection the poor condition of the input bearing was confirmed.
