The Lena spar is a truss spar structure moored in deepwater, supporting topsides facilities for hydrocarbon processing. Subsea wells are connected via flowlines and risers to the platform. The facility performs primary separation of oil, gas, and water, with oil stabilized for export via pipeline. Gas is compressed and exported through subsea gas pipelines, with a portion used for fuel gas. Produced water is treated prior to discharge. The platform includes gas compression systems, separation trains, and water handling units. Power is generated onboard using gas turbines. The spar design provides stability in deepwater and supports dry-tree wells as well as subsea tie-backs. Control systems enable remote monitoring of subsea infrastructure. Export pipelines connect to regional Gulf of Mexico networks, ensuring integration with onshore facilities.
