TurkStream Landfall Facilities

TurkStream consists of the Anapa Landfall Facility, the offshore pipelines and the Kiyikoy Receiving Terminal.

930 kilometers

length of gas pipelines

South Stream Transport B.V. designed and constructed TurkSteam. The company now operates the pipeline system.

The Landfall Facilities connect the offshore section of the pipeline to the onshore gas network. The facility in Turkey is called the Receiving Terminal. This facility also includes offices, control buildings, workshops and warehouses.

Kiyikoy Receiving Terminal

Anapa Landfall Facility

The TurkStream Receiving Terminal distributes the gas to two onshore pipelines. Onshore 1 was built by BOTAŞ and connects to the Turkish gas grid.

Onshore 2 was built by Türk Akım Gaz Taşıma A.Ş., a joint venture between Gazprom and BOTAŞ. This pipeline is directed to the Turkish-Bulgarian border, where it connects to the Bulgarian gas grid.

Russkaya Compressor Station

In Russia, gas first enters the “Russkaya” compressor station. Before the natural gas is transferred to the pipelines, measurements are taken to confirm the contracted flow rate, quality, system pressure and temperature. Although technically not a part of TurkStream, Russkaya is a vital element of the system.

Anapa Landfall Facility

The Landfall Facility in Russia is situated near the city of Anapa on the Black Sea coast. It has a footprint of approximately 7.5 hectares. The facility monitors the pressure, temperature, volume and composition of gas from the Russkaya compressor station. From this point, the gas is distributed between the two offshore lines heading towards Turkey.

Construction of TurkStream’s Landfall Facility near Anapa began in 2014. During construction, the project involved over 5,600 people, 1,200 machine units and dozens of subcontractors.

  • Safety Valves

    There are a number of safety valves at both Landfall Facilities. The majority are shutdown valves, which can immediately interrupt the flow of gas into or out of the pipelines. All valves were designed and produced especially for TurkStream.

  • Water Bath Heaters

    As the heat of natural gas decreases with its pressure when it travels a long distance, it needs to be reheated to the required temperature before it flows to connecting landlines.

  • Metering and monitoring equipment

    The gas streams are checked for quality and then subjected to official measurement via the metering systems.

  • Venting stacks

    The high-integrity pressure protection system (HIPPS) protects the low- pressure side of the terminal from high pressure in the event of an emergency.


    If a malfunction occurs during operation, different sections of the Receiving Terminal can be isolated. Any natural gas still in the system is discharged from two vent stacks. Venting is also performed each year as part of routine maintenance.

Сontrol Centres

The TurkStream system is operated from Turkey and Russia.

The control system network is connected to the sensors and valve controls at both Landfall Facilities by cable and satellite, allowing operators to monitor flow remotely and operate valves at the push of a button.

TurkStream’s operating team of skilled specialists provides 24-hour supervision, 365 days a year.


Kiyikoy’s Receiving Terminal can process 6.5 million cubic meters of natural gas per hour. Inbound natural gas is purified to remove foreign substances and then measured for quality, flow rate, pressure and temperature.


There are isolation and emergency shut-off valves for the pipelines and sensors to monitor pressure and temperature at both facilities.


The fire and gas alarm system consists of sensors which can detect hydrocarbon gas, flame, smoke and any variations in temperature.

The pipelines are inspected externally and internally every few years.

Internal inspection is carried out by the Smart Pipeline Inspection Gauges (PIGs) every few years to identify any corrosion, mechanical defects, or slips. There are PIG launchers and traps at the Landfall Facilities in Russia and Turkey to launch and catch these PIGs. Sent from the PIG launchers in Russia, these smart PIGs will flow with the natural gas along the pipeline and reach the traps in Turkey.

External inspection is carried out on survey ships by remotely operated vehicles (ROVs) operating under water.

50 years

minimal design lifetime of a pipeline

Due to the importance placed on safety and quality during the design and construction of the pipeline, TurkStream is not expected to need any repairs during its 50-year operating lifespan.
