Turbine control systems
Speed and load governing for steam, gas and hydro turbines and the equipment they drive.
- Electronic and electro-hydraulic governors
- Start-up, shutdown and synchronisation sequences
- Control loop tuning
Controls, instrumentation and diagnostics for critical machinery
We help your turbines, compressors, pumps, generators and motors run safely, efficiently and reliably, whatever the manufacturer. We do it through two complementary service lines:
Controls & instrumentation
Control, protection and instrumentation systems for turbomachinery.
Monitoring & diagnostics
Mechanical condition, performance and electrical parameters of your machines.
Line 1 · Controls & instrumentation
Turbomachinery controls and instrumentation
We design, upgrade and maintain the systems that control and protect your machines, from the field sensor to the control room.
Control system upgrades
We replace obsolete governors and panels before a lack of spares or know-how puts operations at risk.
- Obsolescence studies
- Specification, migration, FAT and SAT
- Reuse of existing instrumentation
Protection and safety systems
Overspeed protection, emergency shutdown and safety instrumented functions.
- Overspeed trip systems
- Functional safety (SIL) per IEC 61511
- Proof testing of trip systems
Compressor control
Anti-surge and capacity control to run close to the optimum point without putting the machine at risk.
- Anti-surge control
- Capacity control and load sharing
- Field surge testing
Field instrumentation
Selection, installation, calibration and maintenance of your machines’ instrumentation.
- Speed, pressure, temperature, position and flow
- Valves and actuators
- Calibration and loop troubleshooting
Integration and communications
We connect the machine’s control system to the rest of the plant reliably and securely.
- DCS and SCADA integration
- Industrial protocols: Modbus, Profibus, OPC UA
- Control system cybersecurity
Line 2 · Monitoring & diagnostics
Monitoring and diagnostics for critical machinery
We tell you what condition your machines are in, how well they perform and what is wrong with them, so you can act at the right time.
System implementation
Design, installation and commissioning of machinery monitoring and protection systems, whether new or upgrading existing ones.
- Engineering, specification and documentation
- Sensor, cabling and cabinet installation
- Configuration and alarms per API 670
Remote monitoring
Our analysts remotely review your machines’ vibration, temperature and process data and alert you when something changes.
- Secure remote connection to your system
- Alarms reviewed by a specialist
- Regular asset condition reports
Performance monitoring
We track the efficiency of thermal and hydraulic machines to detect degradation and quantify what it costs.
- Steam and gas turbines, compressors and pumps
- Hydro turbines and generating units
- Heat rate, efficiency and performance curves
Electrical signature analysis
We diagnose motors, generators and the driven machine from voltage and current signals, without stopping the equipment.
- Electrical (ESA) and motor current (MCSA) signature analysis
- Broken rotor bars, eccentricity and stator faults
- Supply quality and driven-load condition
Predictive maintenance
Route-based measurement programmes with portable instruments for machines that don’t need continuous monitoring.
- Vibration analysis
- Thermography and ultrasound
- Criticality analysis and measurement intervals
Machinery diagnostics
Field studies to find the cause of vibration, noise, overheating or recurring failures.
- Spectrum, waveform and orbit analysis
- Resonance studies and modal analysis
- Root cause failure analysis
Balancing and alignment
We correct the most common causes of vibration at your site, without dismantling the machine whenever possible.
- On-site dynamic balancing
- Laser shaft alignment
- Before-and-after verification measurements
Start-up and outage support
We support your team at the riskiest moments for the machine: start-ups, planned outages and overhauls.
- Start-up and shutdown transient recording
- Protection system verification
- Work planning based on machine condition
How we work
From the first assessment to continuous improvement
01
Assessment
We review your machines, their criticality and the state of their controls and instrumentation to decide where to act first.
02
Engineering
We define the technical solution, specify the equipment and prepare the project documentation.
03
Implementation
We install, configure and commission the systems, with testing and final documentation.
04
Support and improvement
We monitor, diagnose and support you throughout the machine’s service life.
Why Sentiec
Reliability engineering, close to your plant
We understand both the machine and the system that controls it. That is why we give you a clear diagnosis and a specific recommendation, not just data.
