Controlling Maintenance Costs

A condition-based monitoring program, devised for the marine industry by SKF, enables ship operators to control costs and avoid damaging equipment breakdown. One operator, Capital Ship Management Corp. (Capital), has been investigating condition monitoring strategies since 2006, in order to reduce the maintenance costs and minimise unexpected machinery and equipment breakdown. Together with SKF, Capital came up with an effective strategy by utilising a new handheld device, launched recently by SKF; the SKF Quick Collect.

The company has implemented the solution across a fleet of 30 vessels, with a plan to extend the

programme for the whole fleet of 56 vessels. SKF helped the company to determine which onboard

machines should be regularly monitored. SKF’s equipment supports ship operators such as Capital to improve the reliability of operations. Onboard engineers use the handheld device to collect vibration data from critical machinery including cargo pumps, engine room fans, compressors, purifiers and electric motors.

Dramatic reduction in costs

George Ioannidis, Technical Fleet Director at Capital says, “This portable vibration measuring instrument helps us to access quick and reliable results for immediate action and reduces the cost of repairs dramatically. Furthermore, the onboard engineers using this vibration device can now collect vibration data from all critical and non-critical machinery including cargo pumps, engine room fans, compressors, purifiers, electric motors etc, and present detailed vibrations reports to class surveyors during periodical machinery survey (CMS).”

The device is small, portable and offers a fast, convenient way to monitor the condition of critical

machinery. The quick, accurate vibration data analysis and its ease of use, makes it a powerful

diagnostic tool, not only for all chief engineers but also for office technical superintendents.

Untrained users

It provides vibration data in real time, allowing engineers to carry out maintenance and replace components immediately if required. The device collects velocity, acceleration enveloping and temperature data and connects with mobile apps such as QuickCollect and ProCollect, accessed via a tablet or smartphone.

It’s easy-to-understand interface means that even a untrained user can understand the principle of

operation and validate results of the vibration data measurements. The system can be customised for

different marine customers, depending on their specific needs.

Vibration data can be viewed in real-time through the app or downloaded and reviewed using Analysis

and Reporting Manager (ARM) software on any accessible PC. Data can also be uploaded to the

cloud, allowing SKF’s onshore vibration analysts to make a more detailed assessment and prepare

a report if needed.

“By giving operators access to data that helps them prioritize maintenance work, our solutions directly

support them in preventing unexpected failures and reducing operating costs,” Petros Petritis, SKF

Marine sales manager concludes.
