Molikpaq was converted from a Canadian Beaufort Sea mobile arctic caisson and enlarged with a 15-metre steel spacer for the deeper Sakhalin location. Its steel caisson rests on a prepared seabed foundation containing approximately 350,000 tonnes of sand ballast. The drilling template was expanded to 32 well conductors. A documented operating stock at the end of 2019 comprised 17 oil-production wells, seven water-injection wells and one drill-cuttings reinjection well. The platform contains drilling and well-intervention equipment, production and test manifolds, multiphase separation, oil conditioning, associated-gas handling, produced-water facilities and water-injection systems. Twelve seawater-supply wells installed within the sand core support platform water requirements. Year-round production became possible after additional power-generation and process modules were installed for Sakhalin-2 Phase 2. Permanent systems also include metering, chemical injection, process control, emergency shutdown, fire-and-gas detection, firewater, flare and relief equipment, telecommunications, cranes, helideck and heated accommodation. Processed oil and associated gas leave through two approximately 17.5-kilometre, 14-inch offshore pipelines to the Sakhalin coast and onward to the Onshore Processing Facility. From there, separated oil and gas enter the parallel Trans-Sakhalin pipeline system running south to Prigorodnoye. Crude is stored at the Prigorodnoye Oil Export Terminal and transferred through its offshore tanker-loading unit; gas continues to the Prigorodnoye LNG plant. Molikpaq itself has no permanent hydrocarbon storage or tanker-loading function under the year-round pipeline-export configuration.
