Michael Hastings and Jonathan Fox, B&K Vibro, detail how a typical condition monitoring and diagnostic solution can be enhanced using a data historian in the LNG industry.
T
he LNG industry is a good potential user of a data historian-based condition monitoring and analytics platform since there are so many machines being monitored, sometimes by several different systems. There are a number of processes in making LNG, but the specific areas where critical machines are monitored include the liquefaction process, the LNG storage and loading process, and power and utilities at the end of the process. B&K Vibro has been a proprietary condition monitoring solution system supplier for more than 23 years. During this time, up to six LNG plants have been monitored, which altogether provide 18% of the world’s LNG production capacity. There are many machines that have been monitored in these LNG plants, both balance of plant and critical. From the company’s experience, a historian-based condition
monitoring solution in the form of PI-based condition monitoring analytics has been proposed, which is relatively new to the LNG industry, but has proven to provide improved benefits.
The standalone proprietary monitoring system vs data historian-based solution
In the beginning, there were only standalone proprietary systems available for condition monitoring; however, with the development of a historian-based condition monitoring analytics solution, new and better monitoring opportunities have been opened up. For those plants that have installed a historian that is also capable of condition monitoring and analytics, chances are
