Located in the Russian Far East near Japan, Sakhalin Island is one of the world's largest oil and gas fields, with an expected lifespan of 50 years and anticipated investments of more than US$100 billion over the next 20 years.
When the Sakhalin II Project began, it was the largest single foreign direct investment project in Russia, with a total investment estimated at US$20 billion (up from originally estimated US$10 billion).
The Sakhalin LNG production facility consists of two tanks, each with an annual liquefaction capacity of 4.8 million tones, making it the largest in the world. However, the natural gas reserves of Sakhalin Island are located in areas frozen for up to 10 months a year. Therefore, the LNG tanks were constructed on the southernmost tip of the island to insure a warm water port for annual export.
To transport this massive reserve of natural gas across the island to the LNG tanks, a pipeline was constructed. Wagners was contracted and responsible for supplying 75,000 m³ of high specification classified sand as pipeline backfill. In all, delivery of the high specification classified sand included 24 locations on the pipeline by either road or rail transportation.
