Pain Points

• Extensive use of motors, valves, sensors, and control loops
• High reliability demands requiring full system redundancy
• Complex testing protocols (FAT, SAT, and communication validation)
• Critical need for diagnostics and visualization of operational conditions

TurkStream

Southstream Transport B.V. manages and maintains the TurkStream pipeline, which extends beneath the Black Sea from Anapa, Russia, to the village of Kıyıköy in Turkey, continuing onward to Europe. Following the completion of a compressor station in Russia, construction began on a reception terminal in Turkey designed to heat, analyze, and reduce the pressure of incoming gas before distribution to customers throughout Turkey and Europe. The client required a highly reliable and secure system that could be monitored remotely from their headquarters in the Netherlands.

The project centered on implementing an Integrated Control and Safety System (ICSS) for the reception terminal. This system encompasses Process Control System (PCS), Safeguarding System (SGS), and Fire and Gas System (FGS). ELCON was tasked with electrical design for PCS, SGS, and telecommunications, which included IT infrastructure, telephony, security, and Public Address General Alarm (PAGA) systems. Additionally, comprehensive documentation, programming for PCS and SGS, SCADA development, and full integration—including the control room, its backup, the compressor station, and the reception terminal—were delivered.

Using Siemens PCS 7 software and an Oil & Gas–specific Siemens library, the PCS and SGS programs were developed. To meet demanding reliability requirements, Siemens S7-400H redundant controllers were deployed. The SCADA system was developed on the WinCC Open Architecture platform, with IEC-104 protocol ensuring seamless communication between SCADA and controllers. Integration of various processing units within the reception terminal was also managed, coordinating with multiple global suppliers to ensure flawless interoperability.

Factory Acceptance Testing (FAT) was conducted using Siemens SIMIT simulation, allowing for early detection of issues and operator training. Site Acceptance Testing (SAT) followed, and ELCON provided on-site assistance during commissioning. The result is a state-of-the-art reception terminal with highly reliable, secure, and scalable control systems. The infrastructure supports minimized downtime, readily available spare parts, and is prepared for future expansion of gas distribution capacity, ensuring smooth and safe operations for years to come.
