VM600Mk2 “one module does it all” concept explained

Like the VM600, the new VM600Mk2 system is designed as a centralised system, with a well-thought-out modular structure allowing smart function combinations that enable complex systems to be built from a minimum number of modules.

Safety integrity levels for overspeed detection system (ODS)

During normal operation, a turbine’s own speed control system regulates the rotational speed of the machine. However, in the event of a problem with the turbine and/or its control system, an overspeed detection system (ODS) provides an isolated layer of protection that will automatically and immediately initiate a shutdown of the machine should this become necessary. In this way, the ODS increases safety, making it easier to meet regulatory requirements, while reducing operating costs such as maintenance and insurance.

Key aspects to consider when selecting an overspeed detection system

According to the API standard 670 for Machinery Protection Systems, an electronic overspeed detection system (ODS) consists of speed sensors, power supplies, output relays, signal processing, and alarm/shutdown/integrity logic. Its function is to continuously measure shaft rotational speed and activate its output relays when an overspeed condition is detected.   API 670 defines multiple requirements […]

Overspeed detection system should always be an isolated layer of protection

An Overspeed Detection System (ODS) has one job and one job only – detect an overspeed event and initiate an emergency trip sequence.
