Sakhalin II Project
Sakhalin Energy Investment Company is the operator of the Sakhalin II project under a Production Sharing Agreement with the Russian Federation. The company was formed in 1994 to develop the Piltun-Astokhskoye oil field and the Lunskoye gas field in the Sea of Okhotsk offshore Sakhalin Island in the Russian Far East.The Sakhalin II project’s main export is Liquified natural gas (LNG).
The Sakhalin II project called for a solution provider that was able to design, install and configure a real time database solution for use within the Sakhalin II project’s distributed landscape; where some assets providing production data are +600km away.
We have successfully installed 14x OPCDA Interfaces configured for hot failover and collecting data for more than 90000 tags. Virtually limitless (by disk only) buffering capability was installed on the interface nodes. A monitoring package based on PI Processbook was provided to simplify the monitoring process of system operations by the System custodian \ Super users of the system.
