Gas turbines serve as the backbone of modern power generation, especially in aviation. These machines boast several advantages, such as light weight, compact size, and quick start-up. The rapid advancements in aviation technology have driven the development of modified gas turbines, which find applications in distributed energy, marine propulsion, pipeline boosting, and offshore platforms. Their effectiveness in these fields cannot be overstated.
Modified aircraft engines possess distinct characteristics that set them apart from traditional power systems:
Based on Proven Technology: They utilize mature aviation engines as their base for modification, ensuring reliability and performance.
Compact and Lightweight Design: These engines feature a smaller footprint and reduced weight, making them suitable for various applications.
Advanced Control Systems: Equipped with sophisticated electronic control systems, these engines achieve rapid start-up times and high levels of automation.
Cost-Effective Modification: The process of converting existing engines into modified versions incurs relatively low costs, making it attractive for operators.
The application of modified gas turbines signifies a shift towards more efficient energy solutions.
Despite the numerous advantages, modified gas turbines face challenges. Short operational intervals and high maintenance costs due to unplanned shutdowns remain significant concerns. To tackle these issues, Bently Nevada offers the 3500/44M module, a four-channel monitoring solution specifically designed for gas turbine vibration monitoring. This module integrates seamlessly into the 3500 framework and accepts inputs from accelerometers and velocity sensors. It triggers alarms when predefined thresholds are exceeded.
The 3500/44M module complies with recommendations from major manufacturers such as General Electric, Rolls-Royce, and Allison. When combined with Bently’s System 1 software, operators gain comprehensive insights into the condition of their equipment. This software facilitates condition monitoring, data analysis, optimization, and diagnostics of alarms and system events.
A notable case study involves a Norwegian oil company utilizing Bently’s 3500 monitoring framework, including the 44M module and System 1 software, on their offshore platform gas turbine units. Initially, the OEM recommended a 2200-hour maintenance interval. However, upon integrating Bently’s System 1, the client observed significant improvements in monitoring their equipment's performance.
Bently’s engineers frequently visited the site, fostering collaboration with the client. They appreciated the detailed data from System 1, particularly concerning critical measurements like combustion chamber noise. With these insights, the client evaluated the engine's operating condition and successfully extended the operational intervals, leading to increased productivity and reduced maintenance costs.
The client aimed to extend the downtime between maintenance from 2200 hours to 2933 hours. This adjustment resulted in fewer planned maintenance sessions annually. As the engine approached the maintenance cycle, the team assessed System 1 data, verifying its accuracy through internal inspections. The use of endoscopes to examine the internal coating and blades confirmed that Bently’s data accurately reflected the engine's condition.
Following these evaluations, the gas turbine was promptly returned to service. The increased focus on Bently’s vibration monitoring system yielded remarkable results. The client eventually achieved an unprecedented maintenance interval of 4400 hours, significantly exceeding their initial expectations. They estimated that this improvement would lead to nearly $30 million in annual revenue increases due to enhanced output and fewer maintenance shutdowns.
The application of Bently products in modified gas turbine condition monitoring demonstrates how innovative solutions can enhance operational efficiency and reliability. By leveraging advanced monitoring technologies, operators can optimize performance, extend maintenance intervals, and ultimately achieve significant cost savings.
