Lunskoye Platform (LUN-A)
Located 15 km off the north eastern coast of Sakhalin Island, in a water depth of 48 m, LUN-A is a drilling and production platform with minimum processing facilities. Oil/condensate and gas separation including gas treatment for transport to the LNG plant is done onshore at the onshore processing facility. This platform produces the majority of the gas for the LNG plant.
Platform Statistics
Design
- Four legged concrete gravity base substructure (CGBS) that was engineered and constructed in Vostochniy port by Aker Kvaerner Technology AS and Quattrogemini OY. PA-B CGBS was installed in June 2005.
- Fully integrated deck construction built separately in South Korea, Samsung Heavy Industries construction yard. The topsides were installed in August 2006 on the pre-installed CGBS by float over technique.
The platform includes drilling and gas/hydrocarbon liquids/water separation facilities, storage for chemicals and a living quarters module. Process, utility equipment and living quarters are separated and located in different areas to maximise safety. The main working areas are enclosed, temperature controlled and ventilated with local winter protection for equipment located in the open. The living quarters have a capacity for 90 permanent and an additional 36 temporary staff.
Production capacity
- Gas approximately 1,800 mln scf/d (52 mln m3/d).
- Condensate about 50,000 b/d (8,000 m3/d).
The LUN-A platform is designed for year-round operation in harsh climatic conditions and is built to withstand rough seas, severe ice and high seismic activity.
The LUN-A was successfully brought on stream in January 2008 by introducing gas to the onshore processing facility.
