Turbine systems are integral components in a wide range of industrial applications, particularly in power generation, mechanical drive systems, and even in some manufacturing processes. In 2024, the steam turbine market size was valued at $23.61 bn while the combustion turbine market was valued at $23.96 bn globally.

This white paper by Munich Re F&C’s Ryan Wood, “Lube oil protection: Lube oil protection systems and common failure modes,” provides an overview of the various types of lube oil systems used in steam and combustion turbines, as well as their primary protection mechanisms. Without a consistent flow of lube oil, rotating machinery is at significant risk. Bearings can quickly overheat, leading to severe damage caused by metal-to-metal contact between the rotating shaft and the bearings.

Loss-of-lube-oil events often result in damaged bearings, thermally affected shafts, compromised seals, and even damage to both rotating and stationary turbine blades. These types of events occur frequently and can lead to significant property losses and business interruptions, representing substantial claims to the insurance market.

In many cases, loss-of-lube-oil events are preventable through proper testing and maintenance. Prioritizing the reliability and protection of lube oil systems is not only critical for operational efficiency but also for protecting plant assets and ensuring long-term financial stability.
