The Sakhalin-2 () project is an oil and gas development in Sakhalin, Russia. It includes development of the Piltun-Astokhskoye oil field and the Lunskoye natural gas field offshore Sakhalin Island in the Okhotsk Sea, and associated infrastructure onshore. The project is managed and operated by Sakhalin Energy.
Sakhalin-2 includes the first liquefied natural gas plant in Russia. The development is situated in areas previously little touched by human activity, causing various groups to criticize the development activities and the impact they have on the local environment.
The decision to proceed with the gas project investment was made in 2003. The expected budget increased dramatically by 2005–2006. The pipeline portion of the gas project was heavily criticized due to environmental issues. Legal proceeding on perceived violation of the Russian environmental regulations were initiated.
In the result, The Russian government ordered to terminate the project in September 2006. Under legal and political pressure, the consortium was forced to sell a majority stake to Gazprom. On 21 December, Gazprom took control over a 50%-plus-one-share stake in the project by signing an agreement with Royal Dutch Shell. Russian President Vladimir Putin attended the signing ceremony in Moscow and indicated that environmental issues had been resolved.
The LNG plant was inaugurated on 18 February 2009. The first cargo was loaded to the LNG carrier Grand Aniva at the end of March 2009.
After the Russian invasion of Ukraine in February 2022, Shell said that it would exit Sakhalin-2 and other ventures in Russia. On 30 June 2022, Russian President Vladimir Putin signed a decree ordering the transfer of the Sakhalin-2 project to a new domestic operator. Foreign investors will be required to apply to retain their existing shares in the new Russian company within a month. The Russian government will then decide whether to allow foreign shareholders to keep their stake. If they are rejected, the government will sell the foreign shareholder’s stake and keep the proceeds in the shareholder’s special account. In April 2023, the Russian government approved the sale of Shell's 27.5% stake to Novatek for RUB 94.8 billion. At the same time, Novatek secured the consent of President Putin so that Shell could withdraw these funds from Russia.
As marine insurance policies come up for renewal, the Japanese government has asked non-life insurance companies to offer war coverage to LNG shippers in Russian waters.Yuka Obayashi, Shri Navaratnam, and Muralikumar Anantharaman.

Sakhalin-II has been exempted from sanctions by the UK and US governments until 28 June 2024.
Sakhalin-2 project includes:
The LNG plant includes:
The LNG plant production capacity is 9.6 million tons of LNG per year. The consortium is examining the possibility of adding another train. A special gas liquefaction process was developed by Shell for use in cold climates such as Sakhalin, based on the use of a double mixed refrigerant.
The LNG plant has two LNG double-walled, storage tanks with a capacity of each. LNG is exported via an jetty in Aniva Bay. The jetty is fitted with four arms – two loading arms, one dual purpose arm and one vapour return arm. The upper deck is designed for a road bed and electric cables. The lower deck is used for the LNG pipeline, communication lines and a footpath. LNG is pumped from the storage tanks into the parallel loading lines which are brought to the LNG jetty. At the jetty head, the pipelines are connected with the jetty's four loading arms. The water depth at the tail of the jetty is .
Technical features
The two fields contain an estimated of crude oil and 500 billion cubic meters (18 trillion cubic feet) of natural gas; 9.6 million tonnes of liquefied natural gas per year and about of oil will be produced. The total project cost until 2014 was originally estimated by Royal Dutch Shell to be between US$9 and $11 billion. However, the costs turned out to be substantially underestimated and in July 2005 Shell revised the estimate upwards to $20 billion.
Piltun-Astokhskoye-A platform
The Molikpaq drilling and oil production platform (Piltun-Astokhskoye-A platform) is an ice-resistant structure, originally built to explore for oil in the Canadian Beaufort Sea. It had been mothballed in 1990, and was installed in the Astokh area of the Piltun-Astokhskoye field, offshore, in September 1998. The Molikpaq has production capacity of of oil and 1.7 million cubic meters of associated gas. [4]
Lunskoye-A platform
The Lunskoye field platform was installed in June 2006 at the Lunskoye gas field offshore. It has production capacity over 50 million cubic meters of natural gas, around of peak liquids (associated water and condensate), and of oil. Lunskoye Platform (LUN-A) www.sakhalinenergy.ru
Piltun-Astokhskoye-B platform
The PA-B platform was installed in July 2007 in the Piltun area of the Piltun-Astokhskoye oil field, offshore. The PA-B has production capacity of of oil and 2.8 million cubic meters of associated gas. PA-B Platform www.sakhalinenergy.ru
Onshore processing facility
The onshore processing facility is located in the north-east of Sakhalin Island, inland in Nogliki. It is designed to process natural gas, condensate, and oil from the Lunskoye and the Piltun-Astokhskoye fields prior to pipeline transportation to the oil export terminal and the liquefied natural gas plant in Aniva Bay in the south of Sakhalin Island. Onshore Processing Facility www.sakhalinenergy.ru
TransSakhalin pipelines
The TransSakhalin pipeline system is designed for transportation of hydrocarbons from the Piltun-Astokhskoye and Lunskoye fields in the North of Sakhalin Island to the onshore processing facility in the Nogliki district and to the LNG plant and the oil export terminal in Aniva Bay. Onshore Pipeline www.sakhalinenergy.ru
Oil export terminal
The oil export terminal is located in Aniva Bay to the east of the LNG plant. It includes the export pipeline and the tanker loading unit, where oil-loading to tankers is performed. Oil Export Terminal www.sakhalinenergy.ru
LNG plant
The Sakhalin-2 LNG plant is the first of its kind in Russia. It is located in Prigorodnoye in Aniva Bay, east of Korsakov. Construction of the LNG plant was carried out by OAO Nipigaspererabothka (Nipigas) and the KhimEnergo consortium, together with two Japanese companies Chiyoda Corporation and Toyo Engineering Corporation. The plant has been designed to prevent major loss of containment in the event of an earthquake and to ensure the structural integrity of critical elements such as emergency shut down valves and the control room of the plant.

Consortium
The projects is owned and operated by Sakhalin Energy. Shareholders of Sakhalin Energy are:
Meanwhile, environmental organizations contend that Sakhalin II had "chronically and substantially violated EBRD's environmental policy".
The consortium applied for nearly a billion dollars in financing from the public export credit agencies of the United States and the United Kingdom, but in early March 2008 these applications were withdrawn due to the drawn-out and uncertain decision-making process] by these banks.
In June 2008 Sakhalin Energy signed Russia's largest project finance deal, securing a loan of US$5.3 billion from the Japan Bank for International Cooperation and a consortium of international banks. Japan Bank for International Cooperation provided $3.7 billion of the funds.
In October 2009 Sakhalin Energy secured an additional $1.4 billion in project financing, bringing the total Phase 2 project financing up to $6.7 billion. The additional debt was provided by a consortium of international commercial banks and insured by Nippon Export and Investment Insurance (NEXI), an Export Credit Agency owned by the Japanese government.
The environmental and social concerns came to a head at the end of November 2005 when the chief executive of WWF, Robert Napier, said that it would have a "negative impact on Sakhalin's people and environment". The WWF asserted that Sakhalin-2 threatens marine life as well as potentially damaging the local communities in the region. Sakhalin Energy responded to the WWF's assertion by saying that the project meets lenders' policies and that environmental and social issues have been met.
In September 2006, Sakhalin Energy briefly suspended construction work on its pipelines. Oleg Mitvol, the deputy chief of the Russian Federal Service for Natural Resources, had announced in early August 2006 that, according to his data, Sakhalin Energy failed to take all actions required to eliminate the danger of the mud flow.
For more than 20 years of operation Sakhalin Energy exercises industrial environmental control of its assets to ensure the compliance with legislation on environmental protection, to observe established environmental regulations, and to provide the rational use of natural resources and fulfilment of the plans for minimising the environmental impact.
The company exercises industrial environmental control in the following areas: – air emissions; – water use and discharge; – waste management. The company has developed and implements the Air Emissions and Energy Management Standard, Water Use Standard and Waste Management Standard. For more details see Sustainable Development Report
In 2006, the International Union for Conservation of Nature set up the Western Gray Whale Advisory Panel (WGWAP). Its members are marine scientists who give independent advice to Sakhalin Energy about managing any potential risks to the Gray whale.
The Far Eastern Regional Hydrometeorological Research Institute is involved in regular monitoring of the western gray whales near the oil and gas developments on the Sakhalin Shelf.
In December 2008, Sakhalin Energy won the Environmental Project of the Year award. The company's protection of the western gray whale population was recognised in the Environmental Efficiency of Economics category. The award was presented by Yuri Trutnev, the Russian Federation's Natural Resources Minister.
The population assessment in 2008 resulted in an estimate of 130 individuals in the western population. No new reproductive females were recorded in 2010, resulting in a minimum of 26 reproductive females being observed since 1995.
Multiple seismic surveys were conducted near Sakhalin in 2010, carried out separately by Rosneft, Sakhalin Energy and Gazprom. The surveys conducted by Sakhalin Energy and Rosneft apparently had corresponding monitoring and mitigation plans. The monitoring data, including acoustic and visual information on whale distribution and behavior, is yet to be analyzed. Two of those seismic surveys occurred later in the year when more gray whales were present and temporally overlapped. Critically endangered North Pacific right whales are also present in the region.Shipulin 2012 А давайте я вам китов покажу, а? . LiveJournal. retrieved on 9 June 2014
Sakhalin Energy in cooperation with Sakhalin-1 operator implementsthe integrated monitoring programme near the north-eastern coast of Sakhalin Island. It shows that the distribution of whales in feeding areas did not vary significantly during the whole period of the study; the number of individuals in the aggregation is increasing, and its reproduction rate is stable. A study was conducted to research the composition, distribution and variability of the communities of gray whale food organisms.
Dredging of Aniva Bay was completed in 2005. In 2005 the salmon harvest was recorded as an all-time high of more than 134,000 tonnes. In 2007 this record was overturned with a salmon catch of 144,181 tonnes.
Sakhalin Energy paid compensation of $110,000 to the Russian Federation to cover potential fish impacts from the Sakhalin-2 project. This compensation was paid regardless of whether any impact was recorded on the fishing industry or not. Part of these funds was used to set up thriving salmon hatcheries on Sakhalin Island.
In 2007, the company started a programme to identify the taimen (a rare protected species of salmon) habitats in the river systems along the pipeline to ensure that production activity will not put the existence of this species at risk.
At the first stage, the distribution and the number of young taimen in several rivers were studied. In 2011, a new phase was launched under the programme, based on the basin-oriented approach to the study of ichthyofauna, including the Sakhalin taimen.
In 2017, ichthyological studies were carried out in the Val River basin. In the course of the work, 29 stations were completed in the main channel, eight — in the tributaries of the river, and two — in the adjoining lakes. In total, 19 species of fish from nine families were identified in the Val River, watercourses and reservoirs in its basin. The family of salmonids was represented by the largest number of species: all four species of the Pacific salmon (genus Oncorhynchus) reproducing in the rivers of Sakhalin, three species of the Arctic salmon of the genus Salvelinus, and the Sakhalin taimen. The family of cyprinids was represented by four species; the remaining families were represented by one species each.
Nevertheless, these concerns were doubted. While preparing for work execution and during the construction, Sakhalin Energy conducted baseline studies and operational monitoring of all crossing areas of water bodies. For the operations phase, a comprehensive observation programme was developed to monitor the most environmentally significant and hydrographically complex water bodies, which allows the company to monitor any changes, to identify critical areas, to develop and take timely corrective measures.
In 2017, the monitoring of hydrological and hydrochemical characteristics and condition of bottom sediments was implemented at 24 water bodies crossed by the pipelines, as well as in the area of potential impact from OPF at the Vatung River, and in the area of the Prigorodnoye production complex at the Mereya River and the Goluboy Brook. In the course of work under the special programme, at the request of oversight bodies, a study was conducted of the Nabil River (with a nameless tributary) and the Nayba River, whose under-river crossings were performed using the horizontal directional drilling (HDD) method.
Monitoring was performed during three hydrological seasons: spring floods, summer low water and autumn high water. Sampling was carried out at two cross sections — the upstream baseline (with no impact from the company's infrastructure assets) and downstream monitoring sections. On most investigated river-crossing sites (from the upstream to the downstream cross sections) no significant horizontal or vertical deformations of river beds were found. The crossings are in satisfactory condition, and no damage to utility lines was found.
In 2017 the River Ecosystems Monitoring did not reveal surface water contamination with oil products. All measurement values were insignificant and in line with MAC standards.
