Innovative split architecture saves time, space and costs while improving safety, operating ease and performance
The turbine is shipped as a pre-assembled, pre-wired, fully tested package. All turbine instrumentation is wired to the on-skid I/O boards during assembly at our plant. Vibration monitoring, computing, interfacing and networking systems are located in a separate control room. Very little on-site cabling is needed compared to traditional control setups where cabling expense can be $250,000 or more. With fewer external auxiliary skids and cables, plus improved enclosure ergonomics, maintainability and availability are also improved.
Safety and reliability are two more key advantages. The system has a network of redundant interconnected Mark VIeS dual controllers, certified for use in applications up to and including SIL3. All activities related to control and IO cards can be done close to the skid by one person instead of two. The skid-mounted panels are certified for use in potentially explosive atmosphere, while the I/O cards, power distribution and load power distribution are designed for maintenance without hot-work permits.
The robust Foundation Fieldbus system extends digital communication strengths to all plant devices, increasing availability of the entire operation and minimizing lost production time by proactively avoiding device failures that were common in the past. This enables condition-based maintenance on field instrumentation.
