Triconex Trident safety system now with rotating machinery modules

Paul Boughton
Invensys Operations Management is releasing version 2.1.1 of its Triconex Trident safety system. This version benefits from two new input modules that enhance worker safety, reduce downtime and deliver more accurate trip analysis in power and turbomachinery applications, thereby helping customers to achieve safety excellence. One new module enables faster response to unsafe equipment conditions, while another optimises trip data analysis to prevent future upsets.
Alejandro Fung, director of safety systems product management at Invensys Operations Management, comments: "Protecting rotating equipment from damage is critical to our customers' operations, and the ability to provide highly accurate plant information helps determine the root cause of trips more effectively, as well as achieve safety excellence. Enhancements to the latest Trident system bring another level of safety to production assets. High reliability, high availability, predictive over-speed condition and high-resolution sequence-of-event information helps customers achieve better uptime and a better understanding of the critical indicators that lead to process shutdowns."
The faster response time of the latest Trident system is the result of an enhanced pulse input module that measures speed, rate-of-speed change and the rate of acceleration of rotating equipment in milliseconds. This enables faster prediction of over-speed conditions, which can otherwise jeopardise personnel, interrupt operations and damage equipment.
Optimised trip analysis is the result of a new high-resolution digital input module that monitors changes of state and sequence of events (SOE) and provides a timestamp resolution of one millisecond with an accuracy of one millisecond. Process trips generate valuable information about the conditions that caused the shutdown. Reviewing and analysing such data can be challenging and time-consuming, however, and having SOE data with a one millisecond resolution can be a significant aid in determining the root cause of the shutdown.
By safely maintaining maximum process uptime, Triconex safety systems can help meet and exceed production targets. The scalable Triconex Trident safety system is based on industry-proven triple modular redundant (TMR) technology that helps customers protect plant personnel and production assets, as well as achieve compliance with rigorous environmental standards by providing high system availability and reliability.
