Prigorodnoye Production Complex is the production complex of the Sakhalin-2 project located in the Korsakovsky urban district of the Sakhalin Region on the banks of Aniva Bay. It includes the first Russian plant for the production of liquefied natural gas (LNG), an oil shipment terminal (OET) and the Prigorodnoye port.

Liquefied Natural Gas (LNG) Plant
The liquefied natural gas plant (LNG plant) is the first such plant in Russia to open up new gas export markets for the country.
History
- The launch ceremony for the LNG plant took place in February 2009. The ceremony was opened by Russian President Dmitry Medvedev . Among the guests of honor at the ceremony were also attended by Japanese Prime Minister Taro Aso , British Prince Andrew , Duke of York, Minister of Economy of the Kingdom of the Netherlands , other high-ranking statesmen from Russia and partner countries for the project.
- The first batch of Russian liquefied natural gas was delivered in March 2009 to Japan.
Design
- two LNG storage tanks with a capacity of 100,000 m³ each;
- LNG loading berth;
- two LNG production lines with a capacity of 4.8 million tons of LNG per year each;
- two spherical tanks for storing refrigerant ( propane and ethane ) of 1600 m³ each (maximum capacity);
- a liquid heat transfer system for supplying heat to various technological consumers;
- five gas turbine generators with a total capacity of approximately 129 MW of electricity;
- auxiliary systems, including instrumentation pneumatic supply station and nitrogen station; as well as diesel fuel systems;
- treatment facilities for the treatment of wastewater and carbon-containing water. Water treatment meets the highest international standards.
Functions
The LNG plant is designed to receive, prepare, process and liquefy natural gas.
Technology
For the cold climatic conditions of Sakhalin Island, a special gas liquefaction technology has been developed based on the use of mixed double refrigerant DMR (Double mixed refrigerant). Shell is the licensor of this technology. This sophisticated technology has been adapted to the conditions of cold Sakhalin winters to ensure maximum performance (air cooling of the refrigerant is applied). Gas turbines of the Frame7 type manufactured by General Electric Co. were used as power drives for the compressors of the main technological refrigeration cycle.
Natural gas cools to a temperature of minus 160 ° C and turns into a liquid state, with a decrease in volume of more than 600 times. This allows you to transport LNG in special gas tankers to regasification terminals of customers.
About 13.8 billion m³ of gas is supplied to the plant annually, mainly from the Lunskoye field . Two parallel production lines carry out the preparation, processing and liquefaction of gas. The following settings are valid for each production line:
- acid gas removal plants;
- gas drying plants on molecular sieves ;
- activated carbon removal plants;
- fractionation plants for the production of refrigerant and stable condensate;
- gas liquefaction plant.
After liquefaction, the gas enters for storage in two isothermal tanks with a volume of 100 thousand m³. The tanks are a double-walled structure with a height of 37 m and a diameter of 67 m. LNG is stored in tanks until the approach of gas tankers.
The plant's capacity is 9.6 million tons of LNG per year.
Oil Shipment Terminal
After the tanker approaches, oil shipment begins.
The oil shipping terminal consists of oil storage tanks, a shipping pipeline and a remote berthing device (VPU) for loading tankers. The terminal is located on the east side of the LNG plant.
Oil storage tanks are vertical cylindrical steel tanks with a “floating” roof with a fire-resistant seal. The diameter of the tanks is 93 m, the height is 18 m. The capacity of each tank is 95.4 thousand m³.
From reservoirs, oil enters the runway through an underwater pipeline. The runway serves as a single-point mooring device and is located at a distance of 4.5 km from the coast. VPU can accept oil tankers with a capacity from 40 thousand m³ to 150 thousand m³.
Operations are managed at the site of the oil shipment terminal from the control center located on the territory of the LNG plant. Automatic control systems ensure stable and safe operation of facilities.
Upgrade
An important event for the Prigorodnoye production complex in August 2016 was the achievement of a high result: more than 11 million man-hours of work without injuries with disability in eight years. The countdown has been going on since August 2008, that is, from the period preceding the start of LNG production. The quality management system of the Prigorodnoye production complex is successfully maintained at the international quality standard ISO 9001.
In 2016, Sakhalin Energy set a new record for LNG production - the daily production volume exceeded the previous record level (recorded in March 2012). In addition, a record LNG production per week was achieved: more than 255 thousand tons of LNG. Previously, maximum weekly production did not exceed 250 thousand tons, the previous record level was recorded in February 2014.
This was made possible thanks to modifications of the main cryogenic heat exchangers of the LNG plant during overhauls in 2015 and 2016, which made it possible to increase their productivity. The high reliability of the gas production and transportation system (from the Lunskoye field through the OPF / NKS No. 1 and NKS No. 2 to the LNG plant) and the high performance of oil production facilities have increased the throughput of the system and, as a result, produce more LNG.

Prigorodnoye Port is Russia's first seaport built specifically for servicing ships carrying liquefied natural gas (LNG) and oil tankers.
History
- The port was named Prigorodnoye in September 2007 from the name of the former village in the south of Sakhalin Island, which was located 13 km south of the city of Korsakov .
- The seaport was opened for foreign vessels by order of the Russian government in May 2008.
- To promote the activities of Sakhalin Energy , a closed joint-stock company Port Prigorodnoye was established in the Prigorodnoye seaport, which is a joint venture on a parity basis between Sakhalin Energy and Sovcomflot .
