Company Overview
Major gas turbine maintenance vendor and spare parts supplier, specializing in turbine technical maintenance needs and performance optimization. Oversees operation and maintenance (O&M) of over 60 turbines across multiple sites; relying on remote monitoring to determine when on-site maintenance is required.
Case Summary:
Industry: Power Generation
Challenge: Provide secure, centralized remote monitoring of turbine O&M data without allowing remote access to the process control network, DCS or turbines.
Solution: OPDS-100D data diode solution selected to transfer OPC DA tags one-way, from turbines to a centralized remote monitoring center.
Benefits: Turbine performance data is available remotely for centralized O&M monitoring, while the process control network and turbines are secured from external cyber threats.
Cybersecurity Challenge
The turbine maintenance service required structured and secure remote monitoring of 60+ turbines at multiple sites for analytics and optimization. However, direct internet access to the turbines would render them vulnerable to cyberattack. The company required a solution which would enable remote monitoring without allowing remote access to the turbines.
Requirements:
- Protect turbines from cyberattack
- Automate transfer of turbine maintenance data from multiple sites to centralized collection point
- Data transfer must be compatible with OPC DA
- Centralized monitoring data must be accessible via web-portal
Use Case | Before 
Solution
OPDS-100D data diode solution selected and deployed at each site to move OPC DA tags one-way, from turbines to remote monitoring web portal for operation and maintenance analytics. Data is collected from over 60 turbines across 9 physical sites, with one data diode at each site supporting all collection. From there the data is passed on to the remote monitoring center where the vendor can perform analytics and provide operation and maintenance recommendations to their customers.

Deployment
Owl Perimeter Defense Solution – 100D (OPDS-100D)
DIN rail compatible data diode solution for deterministic, one-way data transfer and effective network segmentation. Supports a wide range of data formats and transport layer protocols at up to 104 Mbps.
Results
- O&M data securely and automatically collected and transferred to a web-accessible centralized repository
- Systems securely connected via hardware-enforced data diode for one-way-only data transfer
- Data is available offsite for remote monitoring and analytics while the turbines are secured from external access
